将spring-servlet.xml保留在Web应用程序中后，未加载applicationContext.xml [英] applicationContext.xml is not getting loaded when I have kept the spring-servlet.xml in Web application

问题描述

我正在使用Eclipse开发Web应用程序. Spring MVC Web应用程序将得到完善. 我已经创建了servlet xml并将其映射到web.xml中. 一切正常，直到这里& Servlet加载HTML页面 但是现在我想添加一个JPA层. 因此，我在WEB-INF中创建了applicationContext.xml，并将所有与JPA相关的spring配置放入该文件中. 但是，当我启动Web应用程序时，未加载与JPA相关的内容. 我相信的是，applicationContext.xml本身未加载. 我在这里缺少任何想法或其他配置吗?

I am Working on a web application in eclipse. A spring MVC web applicatication to be precised. I have created servlet xml and mapped it in web.xml. Everything is working fine till here & Servlet loads the HTML page But now I want to add a JPA layer. So I have created applicationContext.xml in WEB-INF and put all JPA related spring configurations in that file. But when I start my web application, JPA related stuff is not getting loaded. What I believe is, applicationContext.xml itself is not getting loaded. Any Idea or any other configuration I am missing here?

推荐答案

除非您在web.xml或其他类似的配置文件中配置spring ContextLoaderListener，否则默认情况下不会加载applicationContext.xml文件.

The applicationContext.xml file is not loaded by default unless you configure spring ContextLoaderListener in the web.xml or other similar configuration file.

我假设applicationContext.xml位于WEB-INF文件夹中.

I am assuming that the applicationContext.xml is present inside WEB-INF folder.

  <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
        /WEB-INF/applicationContext.xml
    </param-value>
    </context-param>

如果您有多个配置文件，则可以将它们指定为,分隔的值，例如

If you have multiple configuration files, you can specify them as , separated values like

<param-value> classpath:applicationContext.xml, classpath:securityContext.xml </param-value>

<param-value> classpath:applicationContext.xml, classpath:securityContext.xml </param-value>
