此文章僅供新手參考或老手溫習
一、建立maven web專案，這裡就不多講了.
二、新增pom檔案資訊
<properties> <spring.version>4.3.10.RELEASE</spring.version> <commons-lang.version>2.6</commons-lang.version> <commons-logging.version>1.2</commons-logging.version> <mybatis.version>3.4.5</mybatis.version> <mybatis-spring.version>1.3.1</mybatis-spring.version> <mysql.version>5.1.10</mysql.version> <druid.version>1.0.14</druid.version> <log4j.vresion>1.2.17</log4j.vresion> <jstl.version>1.2</jstl.version> <jsp-api.version>2.2</jsp-api.version> <servlet-api.version>3.1.0</servlet-api.version> <aspectjweaver.version>1.8.13</aspectjweaver.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</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-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>${commons-lang.version}</version> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>${commons-logging.version}</version> </dependency> <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> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.vresion}</version> <!-- <type>bundle</type> --> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${servlet-api.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>${aspectjweaver.version}</version> </dependency> <dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.5</version> </dependency> </dependencies>
三、新增web.xml檔案資訊
<filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
四、springmvc.xml
<context:annotation-config /> <context:component-scan base-package="com.ssm.controller" /> <mvc:annotation-driven /> <mvc:default-servlet-handler/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean>
五、spring-dao.xml
<!-- 資料庫連線池 -->
<!-- 載入配置檔案 -->
<context:property-placeholder location="classpath:config/database.properties"/>
<!-- 資料庫連線池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="maxActive" value="10" />
<property name="minIdle" value="5" />
</bean>
<!-- 讓spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 資料庫連線池 -->
<property name="dataSource" ref="dataSource" />
<!-- 載入mybatis的全域性配置檔案 -->
<!-- <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /> -->
<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>
</bean>
<!-- 自動掃描 將Mapper介面生成代理注入到Spring -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.mapper" />
<!-- <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> -->
</bean>六、spring-service.xml
<context:component-scan base-package="com.ssm.service" />
<!-- 事務管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 資料來源 -->
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 傳播行為 -->
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="create*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
</tx:attributes>
</tx:advice>
<!-- 切面 -->
<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* com.ssm.service.*.*(..))" />
</aop:config>七、database.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root八、Java程式碼部分
1.PageController
@Controller
public class PageController {
@RequestMapping("/")
public String index() {
return "index";
}
}2.UserController
@Controller
@RequestMapping("/users")
public class UsersController {
@Autowired
private UserService userServie;
@RequestMapping("/toAddUser")
public String toAddUser() {
return "addUser";
}
@RequestMapping("/toUpdateUser/{uid}")
public String toUpdateUser(@PathVariable("uid")Integer uid,Map<String,Object> map) {
if(uid != null) {
try {
Users users = userServie.findOne(uid);
map.put("user", users);
} catch (Exception e) {
e.printStackTrace();
}
}
return "updateUser";
}
@RequestMapping("/userinfo")
public String user(Map<String, Object> map) {
List<Users> findAll = userServie.findAll();
map.put("userList", findAll);
return "userinfo";
}
@RequestMapping("/addUser")
@ResponseBody
public String addUser(Users users) {
if(users != null) {
try {
userServie.addUsers(users);
return "success";
} catch (Exception e) {
e.printStackTrace();
return "error";
}
}else {
return "not null";
}
}
@RequestMapping("/updateUser")
@ResponseBody
public String updateUser(Users users) {
if(users != null) {
try {
userServie.updateUsers(users);
return "success";
} catch (Exception e) {
e.printStackTrace();
return "error";
}
}else {
return "not null";
}
}
@RequestMapping("/deleteUser/{uid}")
@ResponseBody
public String deleteUser(@PathVariable("uid")Integer uid) {
if(uid != null) {
try {
userServie.deleteUsers(uid);
return "success";
} catch (Exception e) {
e.printStackTrace();
return "error";
}
}else {
return "not null";
}
}
}3.實體類
public class Users {
private Integer uid;
private String name;
private String username;
private String password;
private String gender;
private Integer age;
private Date createdate;
private Date lastlogindate;
private Integer locked;
get set.......
}4.service和mapper就不貼出來了（mybatis逆向工程就可以直接搞定mapper和pojo）
九、JSP部分
1.userinfo.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<style type="text/css">

margin:0 auto;
width:1000px;
height:300px;
background:#000;
}
td,th{
background:#FFF;
}
</style>
</head>
<body>
<h2>Show User</h2>
<hr>
<table border="0" cellspacing="1">
<tr>
<!-- <th>uid</th> -->
<th>name</th>

<!-- <th>password</th> -->
<th>gender</th>

<th>操作</th>
</tr>
<c:forEach items="${userList }" var="user">
<tr>
<%-- <td>${user.uid}</td> --%>
<td>${user.name}</td>
<td><a href="javascript:void(0);" onclick="updateUser('${user.uid}');">${user.username}</a></td>
<%-- <td>${user.password}</td> --%>

<td>${user.locked}</td>
<td><a href="javascript:void(0);" onclick="deleteUser('${user.uid}','${user.username}');">刪除</a></td>
</tr>
</c:forEach>
</table>
<script type="text/javascript" src="${pageContext.request.contextPath }/js/jquery.min.js"></script>
<script type="text/javascript">
function updateUser(uid){
window.location.href="${pageContext.request.contextPath}/users/toUpdateUser/"+uid;
}
function deleteUser(uid,username){
if(confirm("確定要刪除 "+username+" ?")){
$.post("${pageContext.request.contextPath}/users/deleteUser/"+uid,function(data){
if(data = 'success'){
window.location.href="${pageContext.request.contextPath}/users/userinfo";
}else{
alert(data);
}
});
}
}
</script>
</body>
</html>2.其他JSP頁面就只是畫頁面而已就不貼了
十、最後完整的專案結構
