maven整合ssm框架

1、创建maven web工程

创建完成后，项目结构如下

 

2、项目配置文件

 在pom.xml中添加SSM框架相关jar包的依赖关系，pom.xml代码如下

<?xml version="1.0" encoding="UTF-8"?>

 3、测试

controller

@Controller
public class TestController {

    @Autowired
    public TestService testService;

    @GetMapping("/getNow")
    @ResponseBody
    public String test(){
        String now = testService.getNow();
        return now;
    }
}

service接口

public interface TestService {
    public String getNow();
}

service实现类

@Service
public class TestServiceImpl implements TestService {

    @Autowired
    public TestMapper testMapper;

    @Override
    public String getNow() {
        return testMapper.getNow();
    }
}

mapper接口

public interface TestMapper {

    public String getNow();

}

mapper.xml

<?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="cn.zhuangxp.dao.TestMapper">
    
    <select id="getNow" resultType="java.lang.String">
      select now()
    </select>


</mapper>

配置tomcat,启动项目，访问

http://localhost:8080/getNow
