Spring Boot Web 自定义返回值（通用）

在项目下新建common.entity包，包中包含两个文件Result数据类，ResultCode接口文件

Result.class

@Data
@NoArgsConstructor
public class Result {

    private boolean success;
    private Integer code;
    private String message;
    private Object data;

    private Result(ResultCode code) {
        this.success = code.success;
        this.code = code.code;
        this.message = code.message;
    }

    public Result(ResultCode code,Object data) {
        this.success = code.success;
        this.code = code.code;
        this.message = code.message;
        this.data = data;
    }

    public Result(Integer code,String message,boolean success) {
        this.code = code;
        this.message = message;
        this.success = success;
    }

    public static Result SUCCESS(){
        return new Result(ResultCode.SUCCESS);
    }

    public static Result ERROR(){
        return new Result(ResultCode.SERVER_ERROR);
    }

    public static Result FAIL(){
        return new Result(ResultCode.FAIL);
    }
}

ResultCode

package com.ihrm.common.entity;

public enum ResultCode {

    /**
     * SUCCESS:成功
     * FAIL：失败
     */
    SUCCESS(true,10000,"操作成功！"),
    //---系统错误返回码-----
    FAIL(false,10001,"操作失败"),
    UNAUTHENTICATED(false,10002,"您还未登录"),
    UNAUTHORISE(false,10003,"权限不足"),
    SERVER_ERROR(false,99999,"抱歉，系统繁忙，请稍后重试！");


    boolean success;
    int code;
    String message;

    ResultCode(boolean success,int code, String message){
        this.success = success;
        this.code = code;
        this.message = message;
    }

    public boolean success() {
        return this.success;
    }

    public int code() {
        return this.code;
    }

    public String message() {
        return this.message;
    }

}

枚举中错误码、包括其他字段的命名，可以根据自己需求更改，这里面只是举例。

另外推荐一个IDEA的插件，NR Coding Style,在Marketplace中搜索p3c也可以。是阿里巴巴出的一个代码规范化的提示插件。
