springboot springmvc抛出全局异常的解决方法

springboot中抛出异常，springboot自带的是springmvc框架，这个就不多说了。

springmvc统一异常解决方法这里要说明的是。只是结合了springboot的使用而已。直接上代码，有效有用的才是ok。

1.定义异常捕获

package com.example.rest.error;

import org.springframework.http.httpstatus;
import org.springframework.web.bind.annotation.exceptionhandler;
import org.springframework.web.bind.annotation.responsestatus;
import org.springframework.web.bind.annotation.restcontrolleradvice;
import org.springframework.web.servlet.nohandlerfoundexception;

import javax.validation.constraintviolationexception;

/**
 *
 * @author ming 定义全局异常处理
 * @restcontrolleradvice 是@controlleradvice 与@responsebody 的组合注解
 */
@restcontrolleradvice 
public class globalcontrollerexceptionhandler {

 @exceptionhandler(value = { constraintviolationexception.class })
 @responsestatus(httpstatus.bad_request)
 public apierrorresponse constraintviolationexception(constraintviolationexception ex) {
  return new apierrorresponse(500, 5001, ex.getmessage());
 }
 
 @exceptionhandler(value = { illegalargumentexception.class })
 @responsestatus(httpstatus.bad_request)
 public apierrorresponse illegalargumentexception(illegalargumentexception ex) {
  return new apierrorresponse(501, 5002, ex.getmessage());
 }

 @exceptionhandler(value = { nohandlerfoundexception.class })
 @responsestatus(httpstatus.not_found)
 public apierrorresponse nohandlerfoundexception(exception ex) {
  return new apierrorresponse(404, 4041, ex.getmessage());
 }

 
 @exceptionhandler(value = { exception.class })
 @responsestatus(httpstatus.internal_server_error)
 public apierrorresponse unknownexception(exception ex) {
  return new apierrorresponse(500, 5002, ex.getmessage());
 }
}

2.定义一个返回对象

package com.example.rest.error;

/**
 * @author ming
 */
public class apierrorresponse {

 private int status;
 private int code;
 private string message;

 public apierrorresponse(int status, int code, string message) {
  this.status = status;
  this.code = code;
  this.message = message;
 }

 public int getstatus() {
  return status;
 }

 public int getcode() {
  return code;
 }

 public string getmessage() {
  return message;
 }

 @override
 public string tostring() {
  return "apierrorresponse{" +
    "status=" + status +
    ", code=" + code +
    ", message=" + message +
    '}';
 }
}

3.定义一个启动application

package com.example;

import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
import org.springframework.web.servlet.config.annotation.enablewebmvc;

@springbootapplication
@enablewebmvc 
public class springbootexceptionhandlingapplication {

 public static void main(string[] args) {
  springapplication.run(springbootexceptionhandlingapplication.class, args);
 }
}

4.最后一个测试类

package com.example.rest.controller;

import org.springframework.http.mediatype;
import org.springframework.util.assert;
import org.springframework.web.bind.annotation.getmapping;
import org.springframework.web.bind.annotation.restcontroller;

import javax.validation.constraintviolationexception;
import java.util.collections;

/**
 * @author ming
 */
@restcontroller
public class testcontroller {

 @getmapping(value = "/test", produces = mediatype.application_json_value)
 public void test(long id) {
  assert.notnull(id,"id不能为空!");
  throw new constraintviolationexception("error", collections.emptyset());
 }
}

注意application.properties这个文件的配置

spring.mvc.throw-exception-if-no-handler-found=true 

ok，springboot中解决springmvc异常抛出就可以这样解决了。
