web.xml配置spring监听器

1、可以参考struts的docs文档spring-plugin.html。

2、也可以参考spring的帮助文档的15.4节struts。

• Configure the Spring listener

web.xml

<listener><listenerclass>org.springframework.web.context.ContextLoaderListener</listener-class></listener> <context-param>    <param-name>contextConfigLocation</param-name><!--<param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>-->  <param-value>classpath:beans.xml</param-value></context-param>

默认的路径是>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml，也可以把spring的配置文件放到src目录下，配置就是classpath:beans.xml。其中beans.xml是文件名。

原帮助文档的描述：

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans default-autowire="autodetect"> <bean id="personManager" class="com.acme.PersonManager"/> ...</beans>

More applicationContext configuration files needed?
Since the Spring integration uses a standard Listener, it can be configured to support configuration files other than applicationContext.xml. Adding the following to your web.xml will cause Spring's ApplicationContext to be inititalized from all files matching the given pattern:

<!-- Context Configuration locations for Spring XML files -->

<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value> </context-param>

See the Spring documentation for a full description of this parameter.

注意：

如果beans.xml文件放在src目录下，在生成ApplicationContext ctx=new ClassPathXmlApplicationContext("beans.xml");但若是applicationContext.xml必须放到WEB-INF下的Classes目录下，才能用ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");生成ApplicationContext，若是直接放到WEB-INF下会抛出异常说找不到applicationContext文件
