全局异常处理springmvc

一、实现HandlerExceptionResolver接口

/**
 * springmvc 全局异常处理
 */
@Slf4j
public class GlobalExceptionResolver implements HandlerExceptionResolver{
    @Override
    public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
        //1.一般写日志
        e.printStackTrace();
        log.info(String.format("服务报错了。%s", e.getMessage()));
        //2.短信或者邮件通知管理员
        System.out.println("发邮件或者短信");
        //3.
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("message","你的网络异常，请稍后");
        modelAndView.setViewName("error/exception");
        return modelAndView;
    }
}

二、springmvc.xml文件配置该bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                              http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/mvc
                           http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
                           http://code.alibabatech.com/schema/dubbo
                           http://code.alibabatech.com/schema/dubbo/dubbo.xsd
                              http://www.springframework.org/schema/context
                              http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 配置扫描包 -->
    <context:component-scan base-package="com.taotao.search.controller"></context:component-scan>
    <!--扫描配置文件-->
    <context:property-placeholder location="classpath:properties/*.properties"/>
    <!-- 配置注解驱动 -->
    <mvc:annotation-driven></mvc:annotation-driven>

    <!-- 配置视图解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

    <bean class="com.taotao.search.exception.GlobalExceptionResolver"/>
    <!--引入dubbo服务-->
    <dubbo:application name="taotao-search-web"/>
    <dubbo:registry protocol="zookeeper" address="192.168.1.123:2181"/>

    <dubbo:reference interface="com.taotao.search.service.SearchItemService" id="searchItemService" timeout="300000"/>


</beans>
