添加@ControllerAdvice后报错 Failed to invoke @ExceptionHandler method

Posted 2020-08-03 奋力的蜗牛MMD

首先。单独使用ControllerAdvice 无法正常工作。需要配合@EnableWebMvc 使用。

 

@ControllerAdvice

@EnableWebMvc

pulbic class ExceptionControllerAdvice{

 

　　@ExceptionHandler(NotFoundException.class)

　　@ResponseBody

　　public Map<String,Object> notFoundExc(NotFoundException exc,HttpServletRequest req){

　　.......

　　}

}

在启动之异常处理报错。

错误信息：

xx-servlet.xml中已经配置了messageconverter处理器了。

 

 <bean id="dyMessageConverter" class="com.dooioo.web.converter.DyMappingJacksonHttpMessageConverter"/>

 <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

 

        <!-- spring绑定时处理函数 -->

        <property name="webBindingInitializer">

            <bean class="com.dooioo.init.DefaultBindingInitializer"/>

        </property>

 

        <property name="messageConverters">

            <list>

                <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>

                <ref bean="dyMessageConverter"/>

            </list>

        </property>

        <property name="requireSession" value="false"/>

        <property name="order" value="0"/>

    </bean>

 

上网翻了一遍资料 没有结果。

最后发现和在xml中的顺序有关系。<mvc:annotation-driven/>。

org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter 适配器必须声明在<mvc:annotation-driven />之前，否则不能正常处理参数类型的转换 

 

到此问题解决。
