统一异常处理

1.创建Result类

package com.markLuo.domain;
 
/**
* http请求返回的最外层对象
* Created by markLuo
* 2018-01-21 13:34
*/
public class Result<T> {
 
/** 错误码. */
private Integer code;
 
/** 提示信息. */
private String msg;
 
/** 具体的内容. */
private T data;
 
public Integer getCode() {
return code;
}
 
public void setCode(Integer code) {
this.code = code;
}
 
public String getMsg() {
return msg;
}
 
public void setMsg(String msg) {
this.msg = msg;
}
 
public T getData() {
return data;
}
 
public void setData(T data) {
this.data = data;
}
}

 

2.创建ResultUtil 

package com.markLuo.utils;

import com.markLuo.domain.Result;

/**
 * Created by  markLuo
 * 2018-01-21 13:39
 */
public class ResultUtil {

    public static Result success(Object object) {
        Result result = new Result();
        result.setCode(0);
        result.setMsg("成功");
        result.setData(object);
        return result;
    }

    public static Result success() {
        return success(null);
    }

    public static Result error(Integer code, String msg) {
        Result result = new Result();
        result.setCode(code);
        result.setMsg(msg);
        return result;
    }
}

 

3.使用
