环境配置

1>先创建maven的quickstart项目;并且创建dao层,service层,controller层,po层,mapper,resources以及下面的配置文件(db.properties,log4j.properties,mybatis.xml,spring.xml).

2>配置pom.xml

​修改jdk版本;

​添加依赖:

​ junit版本改为4.12;spring-context;spring-test;spring-jdbc;spring-tx(事务);aspectjweaver(切面编程);c3p0(连接池);mybatis;mybatis-spring;mysql-connector-java(mysql驱动包);slf4j-log4j12,slf4j-api(日志打印);

​设置资源目录和插件

<build> <!-- Maven 项目:如果源代码(src/main/java)存在xml、properties、tld 等文件 Maven 默认不会自动编译该文件到输出目录,如果要编译源代码中xml properties tld 等文件 需要显式配置 resources 标签 --> <resources> <resource> <directory>src/main/resources</directory> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> <include>**/*.tld</include> </includes> <filtering>false</filtering> </resource> </resources> </build>

3>配置spring.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://.xxxx.po.User"> select user_id as userId,user_name as userName,user_pwd as userPwd from tb_user where user_id = #{userId} </select></mapper>

4>添加 UserService.java

@Servicepublic class UserService { @Autowired private UserDao userDao; public User queryUserByUserId(Integer userId){ return userDao.queryUserByUserId(userId); }}

5>添加 UserController.java

@Controllerpublic class UserController { // 注入userService @Resource private UserService userService; /** * 通过用户ID查询用户对象 * @param userId * @return */ public User queryUserByUserId(Integer userId) { User user = userService.queryUserByUserId(userId); return user; }}

执行测试

public class App { public static void main(String[] args) { // 加载Spring的配置 BeanFactory factory = new ClassPathXmlApplicationContext("spring.xml"); // 得到UserController对象 UserController userController = (UserController)factory.getBean("userController"); // 调用方法 User user = userController.queryUserByUserId(1);System.out.println(user.toString()); }}
