摘要：序本文主要聊一下如何在容器啟動(dòng)時(shí)，獲取有自定義注解的方法信息。主要用到這個(gè)方法通過(guò)這個(gè)就可以獲取具體的請(qǐng)求的方法，然后利用反射去判斷是否有標(biāo)注自己所需要的注解。啟動(dòng)時(shí)處理實(shí)現(xiàn)接口，在在中去處理這樣就大功告成了
序
本文主要聊一下如何在spring容器啟動(dòng)時(shí)，獲取有自定義注解的方法信息。
RequestMappingHandlerMappingspring-webmvc-4.3.10.RELEASE-sources.jar!/org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerMapping.java
public class RequestMappingHandlerMapping extends RequestMappingInfoHandlerMapping
implements MatchableHandlerMapping, EmbeddedValueResolverAware {
private boolean useSuffixPatternMatch = true;
private boolean useRegisteredSuffixPatternMatch = false;
private boolean useTrailingSlashMatch = true;
private ContentNegotiationManager contentNegotiationManager = new ContentNegotiationManager();
private StringValueResolver embeddedValueResolver;
private RequestMappingInfo.BuilderConfiguration config = new RequestMappingInfo.BuilderConfiguration();
//....
}
getHandlerMethods
spring-webmvc-4.3.10.RELEASE-sources.jar!/org/springframework/web/servlet/handler/AbstractHandlerMethodMapping.java
/**
* Return a (read-only) map with all mappings and HandlerMethod"s.
*/
public Map getHandlerMethods() {
this.mappingRegistry.acquireReadLock();
try {
return Collections.unmodifiableMap(this.mappingRegistry.getMappings());
}
finally {
this.mappingRegistry.releaseReadLock();
}
}
Map主要用到這個(gè)getHandlerMethods方法
