xml配置spring profiles的几个注意点

先贴正确配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:task="http://www.springframework.org/schema/task"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    <task:annotation-driven/>

    <import resource="spring-datasource.xml"/>
    <import resource="spring-hessian-server.xml"/>
    <import resource="spring-remoting-dis.xml"/>
    <import resource="spring-remoting-worldeye.xml"/>
    <import resource="spring-activemq.xml"/>
    <import resource="spring-cxf-client.xml"/>

    <!-- 开发配置 -->
    <beans profile="dev">
        <context:property-placeholder location="classpath:config/application.properties, classpath:config/application-dev.properties"/>
        <import resource="spring-hadoop-dev.xml"/>
    </beans>

    <!-- 测试配置 -->
    <beans profile="test">
        <context:property-placeholder location="classpath:config/application.properties, classpath:config/application-prd.properties, classpath:config/application-test.properties"/>
        <import resource="spring-hadoop-test.xml"/>
    </beans>

    <!-- 线上配置 -->
    <beans profile="prd">
        <context:property-placeholder location="classpath:config/application.properties, classpath:config/application-prd.properties"/>
        <import resource="spring-hadoop.xml"/>
    </beans>
</beans>

一. xml标签的xsd版本

spring-beans.xsd 文件不要指定版本，也可以使用高版本（起码是3.1)，原因是 spring profile 是3.1版本开始的。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

       ......
       
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

二. dispatcherServlet文件配置

web.xml中配置了 DispatcherServlet 的 contextConfigLocation，需要在 spring-dispatch.xml 添加 spring profile 的配置，配置项同上。

    <!-- profile配置 -->
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>prd</param-value>
    </context-param>

    <!-- Spring配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:config/spring/spring-context.xml
            classpath:config/spring/spring-security.xml
        </param-value>
    </context-param>

   ......

    <!-- Spring Dispatcher配置 -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:config/spring/spring-hessian-server.xml
                classpath:config/spring/spring-dispatch.xml
                classpath:config/spring/spring-security.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
