problem arises



Having recently learned Maven and tried to re-compose the previous project (Springmvc+myabtis) into a MAVEN project, the MAVEN project recommended that the various resource files be placed in the Src/java/resources directory. So I naturally put Spring's config file (including Spring-mvc, Spring-mybatis and other configurations are written in a file) The Applicationcontext.xml file is also placed under the resources directory, and after the refactoring is complete, the Tomcat error is started:

Notice, in fact, the focus is a word, that is Could not open ServletContext resource [/web-inf/applicationcontext.xml], the exception is also very obvious, Filenotexception, unable to open the ServletContext resource file. Let's look at the configuration of Web. XML:

<?xml version= "1.0" encoding= "UTF-8"? ><web-app xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns= "Http://java.sun.com/xml/ns/javaee" xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee/http Java.sun.com/xml/ns/javaee/web-app_3_0.xsd "id=" webapp_id "version=" 3.0 "><display-name>xxybm</ Display-name><listener><listener-class>org.springframework.web.context.contextloaderlistener </listener-class></listener><servlet><servlet-name>springMvc</servlet-name>< servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class><init-param>< param-name>contextconfiglocation</param-name><param-value>classpath:applicationcontext.xml</ param-value></init-param><load-on-startup>2</load-on-startup></servlet>< Servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/app/*</url-pattern ></servlet-mapping><filtEr><filter-name>securityfilter</filter-name><filter-class>net.zhsz.util.logincheckfilter </filter-class></filter><filter-mapping><filter-name>securityfilter</filter-name ><url-pattern>*.jsp</url-pattern></filter-mapping><filter-mapping><filter-name >SecurityFilter</filter-name><url-pattern>/app/*</url-pattern></filter-mapping>< Session-config><session-timeout>30</session-timeout></session-config><error-page> <exception-type>java.lang.Exception</exception-type><location>/500.html</location>< /error-page></web-app>

Because my spring configuration file-- Applicationcontext.xml is placed in the Web-inf root directory, in the project run is normal, after the re-composition of the MAVEN project, my profile should naturally be placed under the Resources folder under SRC, then in Web. XML I will naturally The parameter values for the contextconfiglocation in <init-param> are modified from web-inf/applicationcontext.xml to classpath: Applicationcontext.xml , then after the launch Tomcat still error, And we can see from the error message that the container is still in the Web-inf down to find Applicationcontext.xml, it is clear that the location of the file has been changed by us, and we have also modified the configuration of Web. XML to load from here? The reason is that we are missing another important configuration.



solve the problem



The problem of blind search often does not quickly get an effective solution, so we first look for clues from the official, look at the official spring documents, in the Web chapter can be found in the passage:


Simply translate the marked small paragraph: If you do not intentionally specify a <context-parameter> element with the parameter named Contextconfigloction, Then spring's Contextloderlistener listener will/web-inf/down to find and load the file named Applicationcontext.xml under the directory . So, we should add the <context-param> tag in Web. XML and specify the location of the spring core file again:

<context-param><param-name>contextconfiglocation</param-name><param-value>classpath: Applicationcontext.xml</param-value></context-param>


This will be OK, note that this configuration as far as possible to write in front of the position, because the Web project will initialize the context after Tomcat startup, our configuration is to specify the context configuration of the file location, after the completion of the context initialization should continue to load the remaining various configurations, And our Springmvc servlet is just a configuration of the SPRINGMVC framework, just like the configuration of struts2, and the whole project is managed by spring. The following is the modified Web. XML configuration file:

<?xml version= "1.0" encoding= "UTF-8"? ><web-app xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns= "Http://java.sun.com/xml/ns/javaee" xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee/http Java.sun.com/xml/ns/javaee/web-app_3_0.xsd "id=" webapp_id "version=" 3.0 "><display-name>xxybm</ Display-name><context-param><param-name>contextconfiglocation</param-name><param-value >classpath:applicationContext.xml</param-value></context-param><listener>< Listener-class>org.springframework.web.context.contextloaderlistener</listener-class></listener ><servlet><servlet-name>springMvc</servlet-name><servlet-class> Org.springframework.web.servlet.dispatcherservlet</servlet-class><init-param><param-name> Contextconfiglocation</param-name><param-value>classpath:applicationcontext.xml</param-value ></init-param><load-on-startup>2</load-on-startUp></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern >/app/*</url-pattern></servlet-mapping><filter><filter-name>securityfilter</ filter-name><filter-class>net.zhsz.util.logincheckfilter</filter-class></filter>< filter-mapping><filter-name>securityfilter</filter-name><url-pattern>*.jsp</ Url-pattern></filter-mapping><filter-mapping><filter-name>securityfilter</filter-name ><url-pattern>/app/*</url-pattern></filter-mapping><session-config>< Session-timeout>30</session-timeout></session-config><error-page><exception-type> java.lang.exception</exception-type><location>/500.html</location></error-page></ Web-app>

Finally, start the project again, run normally, spring and SPRINGMVC both load and initialize normally. Before the online search someone said modified path, asterisking number, but also a few jar package, the answer is strange, and then can not solve the problem, in short this blog hope to encounter this unusual friend help, the End.
