## **实例：简单测试** ##

### **测试代码** ###

**controller**

package com.example.controller;
    
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class HelloController {
    
        @GetMapping("/advice")
        public String test() {
            int i = 1 / 0;
            return "test success";
        }
    }

### 测试 ###

访问：[http://localhost:8080/advice][http_localhost_8080_advice]

前端结果：

{
        "message": "全局异常处理/ by zero"
    }

后端结果：

2021-08-18 00:39:20.240 ERROR 31064 --- [nio-8080-exec-1] c.example.config.GlobalExceptionAdvice   : / by zero
    
    java.lang.ArithmeticException: / by zero
    	at com.example.controller.HelloController.test(HelloController.java:11) ~[classes/:na]
    	...

## **实例：项目实战** ##

### **测试代码** ###

**Controller**

package com.example.business.controller;
    
    import com.example.business.entity.User;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    @RequestMapping("user")
    public class UserController {
    
        @GetMapping("fault")
        public void fault() {
            int i = 1 / 0;
        }
    
    }

### 测试 ###

postman访问：[http://localhost:8080/user/fault][http_localhost_8080_user_fault]

postman结果
