Java Web 实用返回结果封装

使用示例

/**

* @Description:

**/
@RestController
@CrossOrigin
@RequestMapping("baofu")
public class ConfigDemoController {

@Autowired
private BaoFooConfig baoFooConfig;

@GetMapping("success")
public Result<String> success() {
return Result.success("success !");
}

@GetMapping("bulid")
public Result<String> bulid() {
return Result.build(ResultEnum.WAIT);
}

@GetMapping("error")
public Result<String> error() {
return Result.success("error !");
}
}

效果

{"code":"0000","msg":"成功","data":"success !"}

{"code":"1111","msg":"正在处理结果","data":null}

{"code":"9999","msg":"error !","data":null}

Result

public class Result<T> {

/**
* 错误码
*/
private String code;

/**
* 提示信息
*/
private String msg;

/**
* 具体的内容
*/
private T data;

/**
* 成功时候的调用
* @param <T>
* @return
*/
public static <T> Result<T> success(T data) {
return new Result<>(data);
}

/**
* 根据返回的状态对象， 构建返回结果
* @param resultEnum
* @param <T>
* @return
*/
public static <T> Result<T> build(ResultEnum resultEnum) {
return new Result<>(resultEnum);
}

/**
* 失败的调用
* @param codeMsg
* @param <T>
* @return
*/
public static <T> Result<T> error(String codeMsg) {
return new Result<>(codeMsg);
}

private Result(T data) {
this.code = ResultEnum.SUCCESS.getCode();
this.msg = ResultEnum.SUCCESS.getMsg();
this.data = data;
}

private Result(String msg) {
this.code = ResultEnum.ERROR.getCode();
this.data = null;
this.msg = msg;
}

private Result(ResultEnum resultEnum) {
this.code = resultEnum.getCode();
this.msg = resultEnum.getMsg();
}
}

ResultEnum

public enum ResultEnum {

SUCCESS("0000", "成功"),
ERROR("9999", "失败"),

WAIT("1111", "正在处理结果");

private String code;

private String msg;

ResultEnum(String code, String msg) {
this.code = code;
this.msg = msg;
}

public String getCode() {
return code;
}

public String getMsg() {
return msg;
}
}
