我有以下配置:
<bean id="mongoDbMessageStore" class="org.springframework.integration.mongodb.store.MongoDbMessageStore">
<constructor-arg ref="mongoDbFactoryDefault"/>
</bean>
<!-- the queue capacity is unbounded as it uses a persistent store-->
<int:channel id="logEntryChannel">
<int:queue message-store="mongoDbMessageStore"/>
</int:channel>
<!-- the poller will process 10 messages every 6 seconds -->
<int:outbound-channel-adapter channel="logEntryChannel" ref="logEntryPostProcessorReceiver" method="handleMessage">
<int:poller max-messages-per-poll="10" fixed-rate="6000"/>
</int:outbound-channel-adapter>
并将消息处理程序定义为
@Override
public void handleMessage(Message<?> message) throws MessagingException {
Object payload = message.getPayload();
if (payload instanceof LogEntry) {
LogEntry logEntry = (LogEntry) payload;
String app = (String) message.getHeaders().get("app");
logger.info("LogEntry Received - " + app + " " …我使用以下代码注册了我的拦截器
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
...
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor( myInterceptor() );
}
...
}
这里是拦截器定义
public class MyInterceptorimplements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
// Check to see if the handling controller is annotated
for (Annotation annotation : Arrays.asList(handler.getClass().getDeclaredAnnotations())){
if (annotation instanceof MyAnnotation){
... do something
但是,handler.getClass().getDeclaredAnnotations()不会返回截获的Controller的类级别注释.
我只能得到方法级注释,这不是我想要的.
相同的拦截器适用于xml配置(使用Spring 3):
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<list>
<ref bean="myInterceptor"/>
</list>
</property>
</bean>
有没有办法在Spring 4中提供类级信息？
