测试工具 Postman使用实例

Postman使用实例

实体类Emp

package com.example.springboot_postman.pojo;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

import javax.persistence.*;

import java.io.Serializable;

/**

* @Author moon

* @Date 2023/10/2 18:29

* @Description

*/

@Entity

@Table(name = "t_emp")

@Data

@AllArgsConstructor

@NoArgsConstructor

@JsonIgnoreProperties(value = { "hibernateLazyInitializer"})

public class Emp implements Serializable {

@Id

@GeneratedValue(strategy = GenerationType.IDENTITY)

@Column(name = "emp_id")

private int id;

@Column(name = "emp_name")

private String name;

@Column(name = "age")

private int age;

@Column(name = "gender")

private String gender;

@Column(name = "email")

private String email;

}

JPA接口EmpDao

package com.example.springboot_postman.dao;

import com.example.springboot_postman.pojo.Emp;

import org.springframework.data.jpa.repository.JpaRepository;

/**

* @Author moon

* @Date 2023/10/2 18:43

* @Description

*/

public interface EmpDao extends JpaRepository {

}

1. 分页查询

EmpService:

public Page queryByPage(Integer page, Integer size) {

Pageable pageable = PageRequest.of(page, size,Sort.by(Sort.Direction.DESC, "id"));

return empDao.findAll(pageable);

}

EmpController

@RequestMapping("/getByPage")

public ResponseEntity> queryByPage(@RequestBody Map map) {

System.out.println(map.get("page") + map.get("size"));

return ResponseEntity.ok(this.EmpService.queryByPage(map.get("page"), map.get("size")));

}

2. 根据id查询

EmpService:

public Emp queryById(Integer id) {

Emp emp = new Emp();

emp.setId(id);

return empDao.getOne(emp.getId());

}

EmpController

@PostMapping

public ResponseEntity add(Emp Emp) {

return ResponseEntity.ok(this.EmpService.insert(Emp));

}

3. 增

EmpService

public Emp insert(Emp emp) {

empDao.save(emp);

return emp;

}

EmpController

@PostMapping

public ResponseEntity add(@RequestBody Emp Emp) {

System.out.println(Emp);

return ResponseEntity.ok(this.EmpService.insert(Emp));

}

4. 删

EmpService

public Boolean deleteById(Integer id) {

Emp emp = new Emp();

emp.setId(id);

empDao.deleteById(emp.getId());

return true;

}

EmpController

@DeleteMapping("{id}")

public ResponseEntity deleteById(@PathVariable Integer id) {

return ResponseEntity.ok(this.EmpService.deleteById(id));

}

5. 改

EmpService

public Emp update(Emp emp) {

empDao.save(emp);

return emp;

}

EmpController

@PutMapping

public ResponseEntity edit(@RequestBody Emp Emp) {

return ResponseEntity.ok(this.EmpService.update(Emp));

}

其中分页管理也可以这样写

@GetMapping

public ResponseEntity> queryByPage(@RequestBody Map map) {

return ResponseEntity.ok(this.EmpService.queryByPage(map.get("page"), map.get("size")));

}

GET请求这样传参数

package com.example.springboot_logback.web;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

@RestController

@RequestMapping("/test")

public class TestController {

// getLogger()的入参是当前类，否则输出日志的类名会是错误的

private final Logger logger = LoggerFactory.getLogger(TestController.class);

@RequestMapping(value = "/test", method = RequestMethod.GET)

public String logTest(String name, String age) {

System.out.println(name + ":" + age);

logger.info("logTest,name:{},age:{}", name, age);

return "success";

}

}

POST请求才用这个格式
