一、代码如下
package com.zxguan; import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler; import javax.servlet.http.HttpServletRequest; /**
* @author zxguan
* @description
* @create 2018-01-29 10:38
*/
@ControllerAdvice
public class GlobalExceptionHandler { @ExceptionHandler(value = NullPointerException.class)
public void nullPointErrorHandler(HttpServletRequest req, Exception e) {
e.printStackTrace();
System.out.println("------------------------ NullPointerException --------------------------");
} @ExceptionHandler(value = Exception.class)
public void defaultErrorHandler(HttpServletRequest req, Exception e) {
e.printStackTrace();
System.out.println("------------------------ Exception --------------------------");
}
}
二、要点
1、@ControllerAdvice
1)basePackages:全局异常捕获包范围
2)basePackageClasses:扫描指定类所在包范围【通常使用一个标记类或接口,通过注解中basePackageClasses定义解析包范围】
