The use of Postman

1. Interface test related library table

CREATE TABLE `t_emp`  (
  `id` int NOT NULL AUTO_INCREMENT,
  `name` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL,
  `salary` double NOT NULL,
  `age` int NOT NULL.PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 15 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of t_emp
-- ----------------------------
INSERT INTO `t_emp` VALUES (2.'Yang Fujun'.9000.19);
INSERT INTO `t_emp` VALUES (8.'Wang Heng Jie'.12000.21);
INSERT INTO `t_emp` VALUES (12.'Deng Zhengwu'.20000.22);
INSERT INTO `t_emp` VALUES (13.'The Lord of Zhou'.18000.23);
INSERT INTO `t_emp` VALUES (14.'Wu Hongxu'.2000.23);

Copy the code

2. Controller layer of POatman test interface meets RestFul style

@RestController
@RequestMapping("tEmp")
public class TEmpController {
    /**
     * 服务对象
     */
    @Resource
    private TEmpService tEmpService;

    /** ** *@paramTEmp Filter criteria *@paramPageRequest page object *@returnQuery result */
    @GetMapping
    public ResponseEntity<Page<TEmp>> queryByPage(TEmp tEmp, PageRequest pageRequest) {
        return ResponseEntity.ok(this.tEmpService.queryByPage(tEmp, pageRequest));
    }

    /** * Query single data ** by primary key@param* id primary key@returnSingle data */
    @GetMapping("{id}")
    public ResponseEntity<TEmp> queryById(@PathVariable("id") Integer id) {
        return ResponseEntity.ok(this.tEmpService.queryById(id));
    }

    /** * Add data **@paramTEmp entity *@returnNew result */
    @PostMapping
    public ResponseEntity<TEmp> add(TEmp tEmp) {
        return ResponseEntity.ok(this.tEmpService.insert(tEmp));
    }

    /** * edit data **@paramTEmp entity *@returnEdit the result */
    @PutMapping
    public ResponseEntity<TEmp> edit(TEmp tEmp) {
        return ResponseEntity.ok(this.tEmpService.update(tEmp));
    }

    /** * delete data **@param* id primary key@returnCheck whether the deletion succeeded */
    @DeleteMapping
    public ResponseEntity<Boolean> deleteById(Integer id) {
        return ResponseEntity.ok(this.tEmpService.deleteById(id)); }}Copy the code

3. Get interface test

• Run the id=8 command to query Wang Hengjie

4. Configure the port environment

• All of our requests so far are port 8080, so you can set up the environment directly

• Click Add Environment

• Add the environment

• Add environment name

• Click on the key environment to add it

• Set the basic access path to http://localhost:8080

• use{{baseUrl}}Use the configured environment variables

5. Realize the deletion function

• Copying an interface

• Delete zhou Xuanjun where id=13

• Delete using postman

  /** * Query single data ** by primary key@param* id primary key@returnSingle data */
    @GetMapping("{id}")
    public ResponseEntity<TEmp> queryById(@PathVariable("id") Integer id) {
        return ResponseEntity.ok(this.tEmpService.queryById(id));
    }


Copy the code

• After successful deletion

• Console print statement

6. Add functions

/** * Add data **@paramTEmp entity *@returnNew result */
    @PostMapping
    public ResponseEntity<TEmp> add(TEmp tEmp) {
        return ResponseEntity.ok(this.tEmpService.insert(tEmp));
    }
Copy the code

• Add employees

• After successful addition

7. Realize the function of uploading files

• Console statement

 @PostMapping("/file")
    public void savePhoto(MultipartFile photo) {
        log.debug("File name" + photo.getOriginalFilename());
        log.debug("File size" + photo.getSize());
        log.debug("File Type" + photo.getContentType());
    }
Copy the code

• Select form-Data for the test interface

• Console result after successful test

8. Implement modification test

• Modify the data before Liu Jianping

• Control layer

/** * edit data **@paramTEmp entity *@returnEdit the result */
    @PutMapping
    public ResponseEntity<TEmp> edit(@RequestBody TEmp tEmp) {
        return ResponseEntity.ok(this.tEmpService.update(tEmp));
    }
Copy the code

• Select Put=> click Body=> Click RAW => Select JSON

• Result after modification
