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
