这是我之前写的统一响应结果集：

public class ResponseResult {

    //状态码
    private int status;

    //消息
    private String message;

    //返回数据
    private Object data;

    public ResponseResult() {
    }

    public ResponseResult(int status, String message, Object data) {
        this.status = status;
        this.message = message;
        this.data = data;
    }

    //成功
    public static ResponseResult success(Object data){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_SUCCESS,"success",data);
    }

    public static ResponseResult success(String message){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_SUCCESS,message,null);
    }

    public static ResponseResult success(){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_SUCCESS,"success",null);
    }

    //失败
    public static ResponseResult fail(){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_FAIL,"fail",null);
    }

    public static ResponseResult fail(Object data){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_FAIL,"fail",data);
    }

    public static ResponseResult fail(String message){
        return new ResponseResult(ResponseStatusConstant.RESPONSE_STATUS_FAIL,message,null);
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getMessage() {
        return message;
    }

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

    public Object getData() {
        return data;
    }

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

常量定义：

public interface ResponseStatusConstant {

    /**
     * 响应状态码，1表示成功
     */
    public static final int RESPONSE_STATUS_SUCCESS=1;

    /**
     * 响应状态码，2表示成功
     */
    public static final int RESPONSE_STATUS_FAIL=2;

    /**
     * 响应状态码，3表示没有权限
     */
    public static final int RESPONSE_STATUS_NO_PERMISSION=3;


}

 

总之，一定要面向切面（AOP）的思想。
