HandlerExceptionResolver全局异常配置类捕捉不到异常
老师你好,我的全局异常配置类无法捕捉异常,当出现异常时直接就抛出来了,不知道是什么原因,怀疑是spring-servlet.xml配置有问题:
<!-- 启动注解驱动的spring mvc 功能 -->
<mvc:annotation-driven/>
<!-- 启动包扫描功能 -->
<context:component-scan base-package="com.mmall.controller"/>
<context:component-scan base-package="com.mmall.service"/>
<!--<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>-->
<bean class="com.mmall.common.SpringExceptionResolver"/>
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
<bean id="jsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
SpringExceptionResolver:
@Slf4j
public class SpringExceptionResolver implements HandlerExceptionResolver {
public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object object, Exception exception) {
String url = httpServletRequest.getRequestURL().toString();
ModelAndView modelAndView;
String defaultErrorMsg = "System Error";
if (url.endsWith(".json")) {
if (exception instanceof PermissionException) {
JsonData jsonData = JsonData.fail(exception.getMessage());
modelAndView = new ModelAndView("jsonView", jsonData.toMap());
} else {
log.error("unknown json Exception,url:",url,exception);
JsonData jsonData = JsonData.fail(defaultErrorMsg);
modelAndView = new ModelAndView("jsonView", jsonData.toMap());
}
} else if (url.endsWith(".page")) {
log.error("unknown page Exception,url:",url,exception);
JsonData jsonData = JsonData.fail(defaultErrorMsg);
modelAndView = new ModelAndView("exception", jsonData.toMap());
} else {
log.error("unknown Exception,url:",url,exception);
JsonData jsonData = JsonData.fail(defaultErrorMsg);
modelAndView = new ModelAndView("jsonView", jsonData.toMap());
}
return modelAndView;
}
}
