ApplicationContext中profile指定解读

如果项目需要在开发环境，测试环境，演示环境或生产环境上相互的切换，如何配置web.xml和ApplicationContext.xml文件。

例如：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <display-name>XXX</display-name>
    <!-- Define the pushlet servlet <servlet> <servlet-name>pushlet</servlet-name>
        <servlet-class>nl.justobjects.pushlet.servlet.Pushlet</servlet-class> <load-on-startup>1</load-on-startup>
        </servlet> -->
    <!-- The pushlet <servlet-mapping> <servlet-name>pushlet</servlet-name>
        <url-pattern>/pushlet.srv</url-pattern> </servlet-mapping> -->
    <servlet>
         <servlet-name>log4j-init</servlet-name>
         <servlet-class>com.cmcc.util.Log4jInit</servlet-class>
         <init-param>
           <param-name>log4j</param-name>
           <param-value>WEB-INF/classes/log4j.properties</param-value>
         </init-param>
         <load-on-startup>0</load-on-startup>
    </servlet>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:spring/applicationContext.xml,
            classpath*:spring/applicationContext-extend.xml
        </param-value>
    </context-param>
    <!-- Spring Context的默认Profile,每次部署不同的环境需要改成对应的配置 -->
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>play</param-value>
        <!-- <param-value>${profile.active}</param-value>-->
    </context-param>
。。。。。
</web-app>

 

定义好

<context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>play</param-value>
        <!-- <param-value>${profile.active}</param-value>-->
    </context-param>

 

然后在ApplicationContext.xml文件中配置

 

<?xml version="1.0" encoding="UTF-8"?>

    </bean>
    。。。。。。
