浅谈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>
