spring 监听器简介
2024-08-30 07:53:30
在java web项目中我们通常会有这样的需求:当项目启动时执行一些初始化操作,例如从数据库加载全局配置文件等,通常情况下我们会用javaee规范中的Listener去实现
常用的监听器有spring的ContextLoaderListener 或者logback
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-application.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
</listener>
<context-param>
<param-name>logbackConfigLocation</param-name>
<param-value>classpath:logback.xml</param-value>
</context-param>
