<body>
<img src="logger.jpg" alt="日志动态配置管理控制台"/>
<p>
恭喜：动态配置操作成功！
<p>
当前的配置为：
<textarea rows="23" cols="123" ReadOnly><%=request.getAttribute("RunningConfig")%></textarea>
<p>
<a href="JavaScript:history.go(-1)">返 回</a>
</body>
</html>
以及一个失败的页面 RefreshFailed.jsp ，代码略
1.7 配置 Spring 的 Bean 文件（Service）
beanRefLog4J.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:LoggerConsole.properties</value>
</list>
</property>
</bean>
<bean id="log4JRefreshInterval" class="net.agile.springtime.logger.util.Log4JRefreshInterval" init-method="init" destroy-method="destroy">
<property name="location" value="${logger.log4j.location}"/>
<property name="refreshDaemon" value="${logger.log4j.refreshDaemon}"/>
<property name="refreshInterval" value="${logger.log4j.refreshInterval}"/>
<property name="refreshSecond" value="${logger.log4j.refreshSecond}"/> <property name="refreshMinute" value="${logger.log4j.refreshMinute}"/> <property name="refreshHour" value="${logger.log4j.refreshHour}"/> </bean>
</beans>
1.8 配置 Spring 的 Bean 文件（MVC）
beanRefMVC.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/log4JRefresh.do">log4JRefreshController</prop>
<prop key="/log4JShutdown.do">log4JShutdownController</prop>
<prop key="/log4JRunning.do">log4JRunningController</prop>
</props>
</property>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
<bean id="log4JRefreshController" class="net.agile.springtime.logger.web.Log4JRefreshController">
<property name="successView" value="RefreshSuccess"/>
<property name="failedView" value="RefreshFailed"/>
<property name="log4JRefreshInterval" ref="log4JRefreshInterval"/>
</bean>
<bean id="log4JShutdownController" class="net.agile.springtime.logger.web.Log4JShutdownController">
<property name="successView" value="RefreshSuccess"/>
<property name="failedView" value="RefreshFailed"/>
<property name="log4JRefreshInterval" ref="log4JRefreshInterval"/>
</bean>
<bean id="log4JRunningController" class="net.agile.springtime.logger.web.Log4JRunningController">
<property name="successView" value="RefreshSuccess"/>
<property name="failedView" value="RefreshFailed"/>
<property name="log4JRefreshInterval" ref="log4JRefreshInterval"/>
</bean>
</beans>
1.9 在你现有的应用中引入这两个 Spring 的配置文件，或者根据你的项目结构进行调整即可
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<import resource="beanRefLog4J.xml" />
<import resource="beanRefMVC.xml" />
</beans>
1.10 配置 web.xml 文件
在 web.xml 中增加 Spring MVC 的配置以及测试用的 Servlet 的配置，完整的配置如下：
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Spring Log4J Refresh Web Application</display-name>
<description>Spring Log4J Refresh Web Application</description>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/beanRefApplication.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>50</load-on-startup>
</servlet>
<servlet>
<servlet-name>HelloServlet</servlet-name>
<display-name>HelloServlet</display-name>
<servlet-class>net.agile.springtime.logger.web.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/HelloServlet</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
这样，你的项目就具有了动态日志配置切换的功能了。
