< 一 > POM 配置文件 ( 如果出現 JAR 包 引入錯誤, 請自行下載 )
<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/maven-v4_0_0.xsd"
>
<!-- maven項目的基本信息 -->
<modelVersion
< 二 > 數據庫基本配置文件
jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf8&useSSL=true
jdbc.class=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.word=920619
< 三 > 配置 Mybatis ( mybatis.xml )
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd"
>
<configuration>
<settings>
<!-- 配置使用 JDBC 驅動獲取自增長主鍵 -->
<setting name="useGeneratedKeys" value="true"/>
<!-- 配置使用列別名替換列名, 默認為TRUE -->
<setting name="useColumnLabel" value="true"/>
<!-- 配置駝峰命名規則 -->
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>
</configuration>
< 四 > DAO 接口
package dao;
import java.util.List;
import java.util.Map;
import model.User;
public interface UserDao {
List<Map<String, Object>> selectAllUser();
Integer insertUser(User user);
}
< 五 > DAO 對應的 Mapper 配置文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd"
>
<mapper namespace="dao.UserDao">
<select id="selectAllUser" resultType="model.User">
SELECT * FROM user
</select>
<insert id="insertUser" parameterType="model.User" keyProperty="userId" >
INSERT INTO user ( user_name, user_sex )
VALUES ( #{userName}, #{userSex} )
</insert>
</mapper>
< 六 > 整合 SPRING + MYBATIS
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context/spring-context-4.1.xsd"

<!-- 加載數據路配置信息 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置 C3P0 數據源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="driverClass" value="${jdbc.class}"/>
<property name="user" value="${jdbc.user}"/>
<property name="password" value="${jdbc.word}"/>
<property name="maxPoolSize" value="30"/>
<property name="minPoolSize" value="10"/>
<property name="autoCommitOnClose" value="false"/>
<property name="checkoutTimeout" value="1000"/>
<property name="acquireIncrement" value="2"/>
</bean>
<!-- 配置 MYBATIS SQL SESSION 工廠 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis.xml"/>
<property name="typeAliasesPackage" value="model"/>
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>
<!-- 配置自動掃描的 DAO 包, 被動態實現註入到 IOC 容器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<property name="basePackage" value="dao"/>
</bean>
</beans>
< 七 > 測試 SPRING + MYBATIS 的整合
package test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import dao.UserDao;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml"})
public class Test01 {
@Autowired
private UserDao userDao;
@Test
public void test() {
System.out.println(userDao.selectAllUser());
}
}
< 八 > 配置 業務層 事務
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"
>
<!-- 配置自動掃描的包 -->
<context:component-scan base-package="service"></context:component-scan>
<!-- 配置事物管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 開啟事物註解配置 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
< 九 > service 例子 ( 接口和實現類 )
package service.inter;
import java.util.List;
import java.util.Map;
import model.User;
public interface UserService {
public List<Map<String, Object>> selectAllUser(User user);
}
package service.imple;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import dao.UserDao;
import model.User;
import service.inter.UserService;
@Service
public class UserImple implements UserService {
@Autowired
private UserDao userDao;
@Override
@Transactional //標誌為事物
public List<Map<String, Object>> selectAllUser(User user) {
userDao.insertUser(user);
// System.out.println(1 / 0);
return userDao.selectAllUser();
}
}
< 十 >測試 SERVICE 配置
package test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import model.User;
import service.inter.UserService;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml", "classpath:spring-service.xml"})
public class Test02 {
@Autowired
public UserService userService;
@Test
public void test(){
User user = new User();
user.setUserName("張崇超");
user.setUserSex(1);
System.out.println(userService.selectAllUser(user));
}
}
< 11 > 配置 SPRING MVC
