最近做了一个项目，需要使用Spring+mybatis+postgresql，下面记录一下整合步骤：
一、准备JAR包：
我使用的是maven，所以直接晒出pom.xml
<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>test.qunar.com</groupId>
<artifactId>web</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging> <name>web</name>
<url>http://maven.apache.org</url> <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties> <dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.7</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.3-1102-jdbc41</version>
</dependency>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
<version>8.0.9</version>
</dependency>
</dependencies>
</project>
二、编写Spring.xml
<?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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"
default-autowire="byName">
<context:property-placeholder location="classpath:jdbc.properties" />
<context:component-scan base-package="com.qunar.study"></context:component-scan>
<import resource="classpath:spring-mybatis.xml"/>
</beans>
三、边写Spring-mybatis.xml
<?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:beans="http://www.springframework.org/schema/beans"
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-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"
default-autowire="byName"> <!-- 引入属性文件 -->
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource"
destroy-method="close" autowire="no">
<property name="fairQueue" value="false" />
<property name="minIdle" value="1" />
<property name="maxIdle" value="5" />
<property name="maxActive" value="5" />
<property name="initialSize" value="1" />
<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="select 1" />
<property name="validationInterval" value="500000" /><!-- 5min -->
<property name="removeAbandoned" value="true" />
<property name="removeAbandonedTimeout" value="30" />
<property name="driverClassName" value="${ticket.database.driver}" />
<property name="url" value="${ticket.database.url}" />
<property name="username" value="${ticket.database.username}" />
<property name="password" value="${ticket.database.password}" />
</bean> <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis/mapper.xml" />
</bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.qunar.study.mapper" />
<property name="sqlSessionFactoryBeanName" value="sessionFactory" />
</bean> <!-- 事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
四、生成代码，这个可以参考上一篇文章：http://www.cnblogs.com/liqiu/p/3869294.html
五、写Service代码：
package com.qunar.study.service.impl;import com.qunar.study.entity.Users;
import com.qunar.study.mapper.UsersMapper;
import com.qunar.study.service.IUsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;@Service("usersService")
public class UsersService implements IUsersService { @Autowired
private UsersMapper usersMapper; public Users getUserById(Integer id) {
return usersMapper.selectByPrimaryKey(id);
}}
六、测试：
具体代码我就不贴出来了，可以直接下载：http://files.cnblogs.com/liqiu/webbak.zip
