无法通过混合XML和JavaConfig加载Spring MVC应用程序(Unable to load Spring MVC Application with Mixing of XML and JavaConfig)
我有一个旧的应用程序，它是基于xml的配置的SPRING MVC应用程序。 由于某些原因，我将它修改为具有XML和Java配置的Spring MVC应用程序。 我在下面提到了两个链接
https://www.mkyong.com/spring/spring-mixing-xml-and-javaconfig/
用spring混合xml和java配置
但它不工作，我想我失去了一些东西。 请通过下面的代码： -

Please advice. Here i don't want to change to complete java configuration.I have an old application which is SPRING MVC application with xml based configuration. Due to some reasons i have modified it as Spring MVC application with XML and Java Configuration. I referred below two links
https://www.mkyong.com/spring/spring-mixing-xml-and-javaconfig/
Mixing xml and java config with spring
But it is not working , i guess i am missing something. Please go through the below code:-

mvc-context.xml应该由调度器servlet加载而不是由根应用程序上下文加载。 将其从AppConfig导入资源中删除。 这条路
根本应用程序上下文（在您的情况下为AppConfig）将由AnnotationConfigWebApplicationContext加载 servlet应用程序上下文mvc-context将由调度程序servlet加载你的web.xml应该是这样的。 app-ctx.xml和mvc-context.xml，如果它们在webapp下不使用classpath，如果它们在资源下使用classpath前缀
<web-app> <context-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support. AnnotationConfigWebApplicationContext </param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>package to .AppConfig</param-value> </context-param> <listener> <listener-class>org.springframework.web.context. ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet. DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>mvc-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>mvc-context.xml should be loaded by the disptacher servlet not by the root application context. remove it from AppConfig import resource. This way
the root application context , which is in your case AppConfig , will be loaded by AnnotationConfigWebApplicationContext servlet application context, mvc-context, will be loaded by the dispatcher servletyour web.xml should be something like this. app-ctx.xml and mvc-context.xml if they are under webapp don't use classpath, if they are under resources use classpath prefix
<web-app> <context-param> <param-name>contextClass</param-name> <param-value> org.springframework.web.context.support. AnnotationConfigWebApplicationContext </param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>package to .AppConfig</param-value> </context-param> <listener> <listener-class>org.springframework.web.context. ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet. DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>mvc-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>更多推荐
