springboot中运行时报错是如何跳转到错误页面：
package com.example.demo.exception; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ResponseBody; import java.util.HashMap; import java.util.Map; @ControllerAdvice //所有Controller运行都会进过这个
public class ExceptionHandler {
//如果报错执行这个方法
@org.springframework.web.bind.annotation.ExceptionHandler(RuntimeException.class)
@ResponseBody
public Map<String,Object> ExceptionHandler(){
Map<String,Object> map = new HashMap<>();
map.put("error：","500");
map.put("msg：","頁面報錯了，請稍後，在重試！！1");
return map;
}
}
