问题 I would like to use a custom NamespaceHandlerResolver when creating a spring application context from xml. The spring documentation only explains how to create custom NamespaceHandler. But I need to use a specifically initialized NamespaceHandlerResolver in order to get the NamespaceHandler s I need to use corretly initialized ( NamespaceHandler s are context dependent). So when creating an xml applicationcontext, how to set a custom NamespaceHandlerResolver ? 回答1: One needs to create an

I know that CXF builds on top of Spring. But I have no experience with Spring and I don't know how it works. I have also seen references to JAXWS in the cxf.xml but I don't know how it is related to either Spring or

问题 Ok I understand the fact that any web application context configured through DispatcherServlet inherits all the beans already defined in the root WebApplicationContext. Nevertheless i have configured some interceptors in my root ApplicationContext <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"> <property name="order" value="2"/> <property name="interceptors"> <list> <ref bean="statisticsInterceptor"/> <ref bean="sessionDiagnosticsInterceptor"/> ..

问题 I have created a spring MVC application. I'm working on spring security concepts. So I've created a context configuration file name webbsite-security.xml and I've given the same file location in the context configuration path. The application fails due to an exception stating that FILENOTFOUNDEXCEPTION(applicationContext.xml not found). Is it necessary that a file named applicationContext.xml should exits even though we use some other configuration files. 回答1: Why would you want to call it

问题 Normally enabling annotations in spring such as @Autowired is done by including this in the spring XML. <context:annotation-config/> Is there a way I can do this programmatically on the ApplicationContext (or implementation) before initialising it? 回答1: Simply using the AnnotationConfigApplicationContext class in the @Configuration class is sufficient. The java based container configuration doesn't depend on doing a component scan in any way. Its merely a different approach for the XML based

问题 Which of these ways is more proper for getting the instance of Application Initialise static field in Application.onCreate() and provide static access to it public class MyApplication extends Application { private static MyApplication sInstance; @Override public void onCreate() { super.onCreate(); sInstance = this; } public static MyApplication getInstance() { return MyApplication.sInstance; } } public class MyBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive

问题 We have a Spring application that is hosted on a shared tomcat instance . Sometimes we have to reload the spring application context but don't want to restart the Tomcat server, because other application's are hosted there as well. Is refreshing springs application context via ((ConfigurableApplicationContext)applicationContext).refresh(); considered bad practice ? What alternatives do I have? 回答1: A few issues that might arise - Firstly, refresh() should destroy all beans currently living in
