SpringMVC 封装返回结果对象

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;
}
}

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);
result.setData(object);
return result;
}

}

public class ExceptionHandle{

@ExceptionHandler(value=Exception.class)

@ResponseBody

public Result handle(Exception e){

return ResultUtil.error(100,e.getMessage());

}

}

*继承RuntimeException事务自动回滚

public　class GirlException extends RuntimeException{

private Integer code;

public GirlException(Integer code,String message){
super(message);
this.code = code;
}

public Integer getCode() {
return code;
}

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