1、首先我这是maven项目，所以你要在pom.xml文件里面加上需要用到的jar配置：
<!-- spring事务,包含了@Transactional标注 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.0.3.RELEASE</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>0.2.9</version> </dependency> <!-- mysqljdbc驱动 ,这个是数据库连接池需要的--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.0.5</version> </dependency>
<!-- 事务：DataSourceTransactionManager --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>3.2.6.RELEASE</version> </dependency>
<!-- 事务aop:config --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.0.3.RELEASE</version> </dependency>
<!-- 事务SqlSessionFactoryBean --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.1</version> </dependency> <!-- 要使用到mybatis，必须要用mybatis这个包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.3</version> </dependency>
2、config.properties内容，也就是数据库链接信息
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://192.168.1.133:3306/salt?characterEncoding=utf-8 jdbc.user=root jdbc.password=root1234
3、Spring配置文件applicationContext.xml文件内容
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:config.properties" /> <!--指定spring注入层 --> <context:component-scan base-package="com.hskj" />
