spring 常用

1. spring在项目初始化时加载类

public class InitDataListener implements InitializingBean, ServletContextAware {

<!-- spring系统启动以后，加载该类，查询所有数据 -->
    <bean class="com.zfsoft.listener.init.InitDataListener" />

2.spring加载远程配置文件

<?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4        xmlns:p="http://www.springframework.org/schema/p"
 5        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
 6 
 7     <bean id="propertyPlaceholderConfigurer"
 8           class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
 9 
10         <!-- during developing, you can uncomment this to load local properties -->
11         <!-- <property name="location" value="application.properties"/> -->
12 
13         <property name="properties">
14             <bean id="remoteProperties" class="org.demo.RemoteProperties"
15                   p:url="http://172.21.12*.**/config/dev/application.properties"/>
16         </property>
17     </bean>
18 
19     <bean class="org.demo.Foo" p:name="${name}"></bean>
20 
21 </beans>
