统一返回结果类

package net.sunofbeach.blog.response;

public class ResponseResult {
    private boolean success;
    private int code;
    private String message;
    private Object data;

    public ResponseResult(ResponseState responseState) {
        this.success = responseState.isSuccess();
        this.code = responseState.getCode();
        this.message = responseState.getMessage();
    }

    public static ResponseResult SUCCESS() {
        return new ResponseResult(ResponseState.SUCCESS);
    }

    public static ResponseResult SUCCESS(String message) {
        ResponseResult responseResult = new ResponseResult(ResponseState.SUCCESS);
        responseResult.setMessage(message);
        return responseResult;
    }

    public static ResponseResult FAILED() {
        return new ResponseResult(ResponseState.FAILED);
    }

    public boolean isSuccess() {
        return success;
    }

    public void setSuccess(boolean success) {
        this.success = success;
    }

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public Object getData() {
        return data;
    }

    public ResponseResult setData(Object data) {
        this.data = data;
        return this;
    }
}

状态列表枚举

package net.sunofbeach.blog.response;

public enum ResponseState {
    SUCCESS(true, 20000, "操作成功"),
    LOGIN_SUCCESS(true, 20001, "登录成功"),
    FAILED(false, 40000, "操作失败"),
    GET_RESOURCE_FAILED(false, 40001, "获取资源失败"),
    LOGIN_FAILED(false, 49999, "登录失败");

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

    private int code;
    private String message;
    private boolean success;

    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public boolean isSuccess() {
        return success;
    }

    public void setSuccess(boolean success) {
        this.success = success;
    }
}
