测试代码运行
SysUserMapper.xml中写入sql
<select id="selectAll" resultMap="BaseResultMap">
select
<include refid="Base_Column_List" />
from sys_user
</select>
dao层的SysUserMapper添加selectAll
package com.example.springboot.dao;
import com.example.springboot.model.SysUser;
import java.util.List;
public interface SysUserMapper {
List<SysUser> selectAll();
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
int deleteByPrimaryKey(Long id);
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
int insert(SysUser record);
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
int insertSelective(SysUser record);
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
SysUser selectByPrimaryKey(Long id);
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
int updateByPrimaryKeySelective(SysUser record);
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table sys_user
*
* @mbggenerated
*/
int updateByPrimaryKey(SysUser record);
}
创建service，serviceImpl以及controller目录
SysUserService
package com.example.springboot.service;
import com.example.springboot.model.SysUser;
import java.util.List;
public interface SysUserService {
List<SysUser> findAll();
}
SysUserServiceImpl
package com.example.springboot.service.serviceImpl;
import com.example.springboot.dao.SysUserMapper;
import com.example.springboot.model.SysUser;
import com.example.springboot.service.SysUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class SysUserServiceImpl implements SysUserService {
@Autowired
private SysUserMapper sysUserMapper;
@Override
public List<SysUser> findAll() {
return sysUserMapper.selectAll();
}
}
SysUserController
package com.example.springboot.controller;
import com.example.springboot.service.SysUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("user")
public class SysUserController {
@Autowired
private SysUserService sysUserService;
@GetMapping(value="/findAll")
public Object findAll() {
return sysUserService.findAll();
}
}
然后启动，访问http://localhost:8080/user/findAll
接下来为了更好的测试，就用Swagger
集成Swagger
pom添加依赖
<!-- swagger -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.8.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.8.0</version>
</dependency>
在config目录下新建Swagger类
package com.example.springboot.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class Swagger {
@Bean
public Docket createRestApi(){
return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any()).build();
}
private ApiInfo apiInfo(){
return new ApiInfoBuilder()
.title("Kitty API Doc")
.description("This is a restful api document of Kitty.")
.version("1.0")
.build();
}
}
启动服务，访问http://localhost:8080/swagger-ui.html#/，出现下面页面，即集成Swagger成功
