文章主要探究了web容器实例化spring的相关配置简单介绍,接下来我们看看具体内容。

web容器中实例化spring相关配置说明:

要想在web容器实例化时加载spring容器,web.xml文件中配置如下:

?
1
2
3
4
5
6
7
8
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:bean.xml</param-value>
</context-param>
<!-- 对Spring容器进行实例化的监听器s -->
<listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

说明:

默认情况下spring实例化时加载的是/WEB-INF/下的applicationContext.xml

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

<param-value>classpath:bean.xml</param-value>指定了spring需要加载的文件(类路径下的bean.xml文件)

如果配置文件有多个配置如下:

?

<context-param>

  <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_modules*.xml
    classpath*:conf/spring/applicationContext_cti*.xml
    classpath*:conf/spring/applicationContext_apm*.xml
