快速集成搭建SSM框架

1.添加maven依赖

7.测试

7.1.Controller

/**
* @author 陈梓平
* @date 2017/11/2.
*/
@RequestMapping
@RestController
public class TestController {
@Autowired
private TestService testService;

@GetMapping(value = "get")
public List<Test> get(){
return testService.get();
}

@GetMapping(value = "get2")
public String get2(){
return "qwhuidhdiuwhqiuw";
}
}

7.2.Service

/**
* @author 陈梓平
* @date 2017/11/2.
*/
public interface TestService {
List<Test> get();
}
/**
* @author 陈梓平
* @date 2017/11/2.
*/
@Service
public class TestServiceImpl implements TestService {

@Autowired
private TestMapper testMapper;

@Override
public List<Test> get() {
List<Test> tests = testMapper.queryTestInfo();
return tests;
}
}

7.3.mapper

/**
* @author 陈梓平
* @date 2017/11/2.
*/
public interface TestMapper {
List<Test> queryTestInfo();
}

7.4.entity

/**
* @author 陈梓平
* @date 2017/11/2.
*/
public class Test {
private int id;
private String name;

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

@Override
public String toString() {
return "Test{" +
"id=" + id +
", name='" + name + '\'' +
'}';
}
}

7.5.mybatis映射文件

<?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="com.chen.logic.mapper.TestMapper">

<select id="queryTestInfo" resultType="com.chen.logic.entity.Test">
SELECT * FROM test
</select>

</mapper>

8.配置Tomcat测试

9.运行测试
