spring+Mybatis+通用mapper+分頁助手+restful風格的編寫使用案例
阿新 • • 發佈：2019-01-26
一、基本環境
IDE：Eclipse Java EE IDE for Web Developers Version: Neon Release (4.6.0)JDK：1.8
Mysql：mysql-5.6.24
maven：maven3.3.9
Tomcat：tomcat9
二、專案基本搭建
1、建立資料庫
首先建立一個測試資料庫mybatis,在該資料庫中建立一個數據表tb_user,建立語句如下：
2、建立maven的父專案CREATE TABLE `tb_user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `user_name` varchar(100) DEFAULT NULL COMMENT '使用者名稱', `password` varchar(100) DEFAULT NULL COMMENT '密碼', `name` varchar(100) DEFAULT NULL COMMENT '姓名', `age` int(10) DEFAULT NULL COMMENT '年齡', `sex` tinyint(1) DEFAULT NULL COMMENT '性別，1男性，2女性', `birthday` date DEFAULT NULL COMMENT '出生日期', `created` datetime DEFAULT NULL COMMENT '建立時間', `updated` datetime DEFAULT NULL COMMENT '更新時間', PRIMARY KEY (`id`), UNIQUE KEY `username` (`user_name`) ) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8
建立一個pom工程：kang-parent，其pom.xml內容如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.kang.parent</groupId> <artifactId>kang-parent</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>pom</packaging> <!-- 集中定義依賴版本號 --> <properties> <junit.version>4.10</junit.version> <spring.version>4.1.3.RELEASE</spring.version> <mybatis.version>3.2.8</mybatis.version> <mybatis.spring.version>1.2.2</mybatis.spring.version> <mybatis.paginator.version>1.2.15</mybatis.paginator.version> <mysql.version>5.1.32</mysql.version> <slf4j.version>1.6.4</slf4j.version> <jackson.version>2.4.2</jackson.version> <druid.version>1.0.9</druid.version> <httpclient.version>4.3.5</httpclient.version> <jstl.version>1.2</jstl.version> <servlet-api.version>2.5</servlet-api.version> <jsp-api.version>2.0</jsp-api.version> <joda-time.version>2.5</joda-time.version> <commons-lang3.version>3.3.2</commons-lang3.version> <commons-io.version>1.3.2</commons-io.version> </properties> <dependencyManagement> <dependencies> <!-- 單元測試 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis.spring.version}</version> </dependency> <!-- MySql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- Jackson Json處理工具包 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <!-- 連線池 --> <dependency> <groupId>com.jolbox</groupId> <artifactId>bonecp-spring</artifactId> <version>0.8.0.RELEASE</version> </dependency> <!-- httpclient --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>${httpclient.version}</version> </dependency> <!-- JSP相關 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servlet-api.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> <scope>provided</scope> </dependency> <!-- 時間操作元件 --> <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> <version>${joda-time.version}</version> </dependency> <!-- Apache工具元件 --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>${commons-lang3.version}</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>${commons-io.version}</version> </dependency> </dependencies> </dependencyManagement> <build> <finalName>${project.artifactId}</finalName> <plugins> <!-- 資原始檔拷貝外掛 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.7</version> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> <!-- java編譯外掛 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> <pluginManagement> <plugins> <!-- 配置Tomcat外掛 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> </plugin> </plugins> </pluginManagement> </build> </project>
3、建立子專案
建立一個war工程kang-usermanage，其pom.xml檔案內容如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.kang.parent</groupId> <artifactId>kang-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <groupId>com.kang.usermanage</groupId> <artifactId>kang-usermanage</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <!-- 單元測試 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>3.7.5</version> </dependency> <dependency> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> <version>0.9.1</version> </dependency> <!-- 通用Mapper --> <dependency> <groupId>com.github.abel533</groupId> <artifactId>mapper</artifactId> <version>2.3.4</version> </dependency> <!-- MySql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </dependency> <!-- Jackson Json處理工具包 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </dependency> <!-- 連線池 --> <dependency> <groupId>com.jolbox</groupId> <artifactId>bonecp-spring</artifactId> </dependency> <!-- JSP相關 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <scope>provided</scope> </dependency> <!-- Apache工具元件 --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> </dependency> </dependencies> <build> <!-- 配置外掛 --> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <url>http://localhost:8081/manager/text</url> <server>tomcat7</server> <port>8081</port> <path>/</path> <username>tomcat</username> <password>123456</password> </configuration> </plugin> </plugins> </build> </project>
三、配置檔案詳解
1、mysql的外部屬性檔案:jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/mybatis?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
jdbc.username=root
jdbc.password=root在這裡集成了分頁助手和通用mapper。注意，分頁助手的配置要放在通用mapper之前。

log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n1、通用頁面跳轉
package com.kang.mybatis.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
//通用的頁面跳轉Controller
@RequestMapping("page")
@Controller
public class PageController {
@RequestMapping(value = "{pageName}", method = RequestMethod.GET)
public String toPage(@PathVariable("pageName") String pageName) {
return pageName;
}
}2、封裝EasyUIResult
package com.kang.mybatis.bean;
import java.util.List;
public class EasyUIResult {
private Long total;
private List<?> rows;
public EasyUIResult() {
}
public EasyUIResult(Long total, List<?> rows) {
this.total = total;
this.rows = rows;
}
public Long getTotal() {
return total;
}
public void setTotal(Long total) {
this.total = total;
}
public List<?> getRows() {
return rows;
}
public void setRows(List<?> rows) {
this.rows = rows;
}
}3、編寫mapper介面，此介面繼承通用mapper
package com.kang.mybatis.mapper;
import com.github.abel533.mapper.Mapper;
import com.kang.mybatis.pojo.User;
public interface NewUserMapper extends Mapper<User>{
}4、新增pojo類
package com.kang.mybatis.pojo;
import java.util.Date;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Table(name = "tb_user")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
// 使用者名稱
private String userName;
// 密碼
private String password;
// 姓名
private String name;
// 年齡
private Integer age;
// 性別，1男性，2女性
private Integer sex;
// 出生日期
private Date birthday;
// 建立時間
private Date created;
// 更新時間
private Date updated;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getuserName() {
return userName;
}
public void setuserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public Integer getSex() {
return sex;
}
public void setSex(Integer sex) {
this.sex = sex;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public Date getCreated() {
return created;
}
public void setCreated(Date created) {
this.created = created;
}
public Date getUpdated() {
return updated;
}
public void setUpdated(Date updated) {
this.updated = updated;
}
@Override
public String toString() {
return "User [id=" + id + ", userName=" + userName + ", password=" + password + ", name=" + name
+ ", age=" + age + ", sex=" + sex + ", birthday=" + birthday + ", created=" + created
+ ", updated=" + updated + "]";
}
}5、編寫service方法
package com.kang.mybatis.service;
import java.util.Date;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.github.abel533.entity.Example;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.kang.mybatis.bean.EasyUIResult;
import com.kang.mybatis.mapper.NewUserMapper;
import com.kang.mybatis.pojo.User;
@Service
public class NewUserService {
@Autowired
private NewUserMapper newUserMapper;
public EasyUIResult queryUserList(Integer page, Integer rows) {
// 設定分頁引數
PageHelper.startPage(page, rows);
// 設定查詢條件
Example example = new Example(User.class);
example.setOrderByClause("created DESC"); // 設定排序條件
List<User> users = this.newUserMapper.selectByExample(example);
PageInfo<User> pageInfo = new PageInfo<User>(users);
return new EasyUIResult(pageInfo.getTotal(), pageInfo.getList());
}
public User queryUserById(Long id) {
return this.newUserMapper.selectByPrimaryKey(id);
}
public void saveUser(User user) {
user.setCreated(new Date());
user.setUpdated(new Date());
this.newUserMapper.insertSelective(user);
}
public void updateUser(User user) {
this.newUserMapper.updateByPrimaryKeySelective(user);
}
public void deleteUserById(Long id) {
this.newUserMapper.deleteByPrimaryKey(id);
}
}6、編寫controller方法
package com.kang.mybatis.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.kang.mybatis.bean.EasyUIResult;
import com.kang.mybatis.pojo.User;
import com.kang.mybatis.service.NewUserService;
@RequestMapping("user")
@Controller
public class UserController {
// @Autowired
// private UserService userService;
@Autowired
private NewUserService userService;
@RequestMapping(value = "list", method = RequestMethod.GET)
@ResponseBody
public EasyUIResult queryUserList(@RequestParam(value = "page", defaultValue = "1") Integer page,
@RequestParam(value = "rows", defaultValue = "5") Integer rows) {
return this.userService.queryUserList(page, rows);
}
//查詢資料
@RequestMapping(value="{userId}",method=RequestMethod.GET)
public ResponseEntity<User> quseryUserById(@PathVariable("userId") Long userId){
try {
User user=this.userService.queryUserById(userId);
if(null==user){
//返回404資源不存在
return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null);
}
//返回200，成功
//return ResponseEntity.status(HttpStatus.OK).body(user);
return ResponseEntity.ok(user);
} catch (Exception e) {
e.printStackTrace();
}
//查詢出錯，返回500
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(null);
}
//新增資料
@RequestMapping(method=RequestMethod.POST)
public ResponseEntity<Void> saveUser(User user){
try {
this.userService.saveUser(user);;
return ResponseEntity.status(HttpStatus.CREATED).build();
} catch (Exception e) {

}7、編寫對通用mapper的單元測試檔案
package com.kang.mabatis.test;
import static org.junit.Assert.fail;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import org.junit.Before;
import org.junit.Test;

public class NewUserMapperTest {
private NewUserMapper newUserMapper;
@Before
public void setUp() throws Exception {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
"classpath:spring/applicationContext*.xml");
this.newUserMapper = applicationContext.getBean(NewUserMapper.class);
}
@Test
public void testSelectOne() {
User record = new User();
// 設定查詢條件
record.setuserName("zhangsan");
record.setPassword("123456");
User user = this.newUserMapper.selectOne(record);
System.out.println(user);
}
@Test
public void testSelect() {
User record = new User();

}
}
@Test
public void testSelectCount() {
System.out.println(this.newUserMapper.selectCount(null));
}
@Test
public void testSelectByPrimaryKey() {
//注意selectByPrimaryKey的輸入引數必須是Long型，不能是string型別。new Long(1)

System.out.println(user);
}
@Test
public void testInsert() {

//record.setPassword("123456");
record.setSex(1);
record.setUpdated(new Date());
//使用所有的欄位作為插入語句的欄位
int count = this.newUserMapper.insert(record);
System.out.println(count);
System.out.println(record.getId());
}
@Test
public void testInsertSelective() {

//將不為null的欄位作為插入語句的欄位
int count = this.newUserMapper.insertSelective(record);
System.out.println(count);
System.out.println(record.getId());
}
@Test
public void testDelete() {
// this.newUserMapper.delete(null);
}
@Test
public void testDeleteByPrimaryKey() {
System.out.println(this.newUserMapper.deleteByPrimaryKey(9L));
}
@Test
public void testUpdateByPrimaryKey() {
fail("Not yet implemented");
}
@Test
public void testUpdateByPrimaryKeySelective() {
User record = new User();
record.setId(1L);
record.setAge(24);
this.newUserMapper.updateByPrimaryKeySelective(record);
}
@Test
public void testSelectCountByExample() {
fail("Not yet implemented");
}
@Test
public void testDeleteByExample() {
fail("Not yet implemented");
}
@Test
public void testSelectByExample() {
Example example = new Example(User.class);
List<Object> values = new ArrayList<Object>();
values.add(1L);
values.add(2L);
values.add(3L);
//批量查詢
//example.createCriteria().andIn("id", values);
//單個查詢
example.createCriteria().andEqualTo("id", 1L);
List<User> list = this.newUserMapper.selectByExample(example);
for (User user : list) {
System.out.println(user);
}
}
@Test
public void testUpdateByExampleSelective() {
fail("Not yet implemented");
}
@Test
public void testUpdateByExample() {
fail("Not yet implemented");
}
}五、專案測試
1、查詢所有資訊
資料庫內容如下：
在瀏覽器中輸入: http://127.0.0.1:8081/rest/page/users
得到頁面如下：前端頁面基於easyUI實現，資料按照更新時間排序。
2、restful的相關測試
(1)使用get獲取資料
(2)使用post提交資料
資料庫資料：
(3)使用put更新資料
資料庫資料：
（4）使用delete刪除資料
資料庫資料：
