spring - 如何将detectHandlerMethodsInAncestorContexts设置为true？

在spring-webmvc中，AbstractHandlerMethodMapping.java中有一个参数detectHandlerMethodsInAncestorContexts。

其默认值为false。如何设置为真？

最佳答案

只需显式创建RequestMappingHandlerMapping bean并将此值设置为true

@Bean
public RequestMappingHandlerMapping requestMappingHandlerMapping() {
    RequestMappingHandlerMapping requestMappingHandlerMapping = new RequestMappingHandlerMapping();
    requestMappingHandlerMapping.setDetectHandlerMethodsInAncestorContexts(true);
    return requestMappingHandlerMapping;
}
