web container instantiates spring related configuration resolution

This article explores the configuration associated with instantiating spring in the web container. Let's take a look at the details.

spring instantiation in web container

To load the spring container when the web container is instantiated, the configuration in the ES12en.xml file is as follows:

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:bean.xml</param-value>
</context-param>
<!--  right Spring The listener that the container instantiates s -->
<listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Description:

By default, spring instantiation loads applicationContext.xml under/WEB-ES22en /

< param-name > contextConfigLocation < /param-name >

< param-value > classpath:bean.xml < /param-value > Specifies the file that spring needs to load (bean.xml file under the classpath)

If the profile has multiple configurations as follows:

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
      classpath*:conf/spring/applicationContext_core*.xml,
      classpath*:conf/spring/applicationContext_dict*.xml,
      classpath*:conf/spring/applicationContext_hibernate.xml,
      classpath*:conf/spring/applicationContext_staff*.xml,
      classpath*:conf/spring/applicationContext_security.xml
      classpath*:conf/spring/applicationContext_modules*.xml
      classpath*:conf/spring/applicationContext_cti*.xml
      classpath*:conf/spring/applicationContext_apm*.xml
    </param-value>
  </context-param>

Or (separated by Spaces, configured as follows :)

     <CONTEXT-PARAM>
     <PARAM-NAME>contextConfigLocation</PARAM-NAME>
     <PARAM-VALUE>
        applicationContext-database.xml applicationContext.xml
     </PARAM-VALUE> 
   </CONTEXT-PARAM>
