SpringBoot项目ResponseEntity返回总结

ResponseEntity进行CRUD

这题是使用ResponseEntity进行返回值，不包含通用异常处理。

1、查询

@GetMapping("queryall")
    public ResponseEntity<List<Announceconsultsituation>> queryAll(){
        try {
            List<Announceconsultsituation> announceconsultsituations = announceconsultsituationService.queryList(new Announceconsultsituation());
            if(CollUtil.isEmpty(announceconsultsituations)){
                return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null);
            }
            return ResponseEntity.ok(announceconsultsituations);
        }catch (Exception e){
            e.printStackTrace();
        }
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }

@GetMapping("queryone")
    public ResponseEntity<List<Announceconsultsituation>> queryone(){
        try {
            Announceconsultsituation announceconsultsituation = announceconsultsituationService.queryOne(id);
            if(announceconsultsituation==null){
                return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null);
            }
            return ResponseEntity.ok(announceconsultsituation);
        }catch (Exception e){
            e.printStackTrace();
        }
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }

2、添加

@PostMapping("add")
    public ResponseEntity<Void> add(Announceconsultsituation announceconsultsituation){
        try {
            int count = announceconsultsituationService.add(announceconsultsituation);
            // 添加数据成功，返回201
            if(count == 1){
                return ResponseEntity.status(HttpStatus.CREATED).build();
            }
        }catch (Exception e){
            e.printStackTrace();
        }
        // 执行失败或者发生异常，返回500
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }

3、修改

@PutMapping("update")
    public ResponseEntity<Void> update(Announceconsultsituation announceconsultsituation){
        try {
            int count = announceconsultsituationService.update(announceconsultsituation);
            // 正常更新数据，返回204
            if(count == 1){
                return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
            }
        }catch (Exception e){
            e.printStackTrace();
        }
        // 执行失败或者发生异常，返回500
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }

4、删除

@DeleteMapping("del/{id}")
    public ResponseEntity<Void> delete(@PathVariable("id") Integer id){
        try {
            //参数没有或者格式错误，返回400
            if(id == null){
                return ResponseEntity.status(HttpStatus.BAD_REQUEST).build();
            }
            int count = announceconsultsituationService.delete(id);
            // 正常删除，返回204
            if(count == 1){
                return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
            }
        }catch (Exception e){
            e.printStackTrace();
        }
        // 执行失败或者发生异常，返回500
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }

自定义ResponeBean进行CRUD

自定义的ResponseBean

public class RespBean {
    private Integer status;
    private String msg;
    private Object obj;

    public static RespBean build() {
        return new RespBean();
    }

    public static RespBean ok(String msg) {
        return new RespBean(200, msg, null);
    }

    public static RespBean ok(String msg, Object obj) {
        return new RespBean(200, msg, obj);
    }

    public static RespBean error(String msg) {
        return new RespBean(500, msg, null);
    }

    public static RespBean error(String msg, Object obj) {
        return new RespBean(500, msg, obj);
    }

    private RespBean() {
    }

    private RespBean(Integer status, String msg, Object obj) {
        this.status = status;
        this.msg = msg;
        this.obj = obj;
    }

    public Integer getStatus() {
        return status;
    }

    public RespBean setStatus(Integer status) {
        this.status = status;
        return this;
    }

    public String getMsg() {
        return msg;
    }

    public RespBean setMsg(String msg) {
        this.msg = msg;
        return this;
    }

    public Object getObj() {
        return obj;
    }

    public RespBean setObj(Object obj) {
        this.obj = obj;
        return this;
    }
}

1、查询

@GetMapping("/")
	public List<JobLevel> getAllJobLevels() {
		return jobLevelService.getAllJobLevels();
}

2、增加

@PostMapping("/")
public RespBean addJobLevel(@RequestBody JobLevel jobLevel) {
	if (jobLevelService.addJobLevel(jobLevel) == 1) {
    	return RespBean.ok("添加成功!");
    }
    return RespBean.error("添加失败!");
}

3、更新

@PutMapping("/")
public RespBean updateJobLevelById(@RequestBody JobLevel jobLevel) {
	if (jobLevelService.updateJobLevelById(jobLevel) == 1) {
    	return RespBean.ok("更新成功!");
    }
    return RespBean.error("更新失败!");
}

4、删除

@DeleteMapping("/{id}")
public RespBean deleteJobLevelById(@PathVariable Integer id) {
	if (jobLevelService.deleteJobLevelById(id) == 1) {
    	return RespBean.ok("删除成功!");
    }
    return RespBean.error("删除失败!");
}
