研究了一下,还好,比较简单,只要替换 上一篇文章第4步的配置文件( spring-disconf.xml)即可。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd"> <!-- 使用disconf必须添加以下配置 --> <bean id="disconfMgrBean" class="com.baidu.disconf.client.DisconfMgrBean" destroy-method="destroy"> <property name="scanPackage" value="com.baidu"/> </bean> <bean id="disconfMgrBean2" class="com.baidu.disconf.client.DisconfMgrBeanSecond" init-method="init" destroy-method="destroy"> </bean> <!-- 使用托管方式的disconf配置(无代码侵入, 配置更改自动reload)--> <bean id="configproperties_disconf" class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean"> <property name="locations"> <list> <value>config.properties</value> </list> </property> </bean> <bean id="propertyConfigurer" class="com.baidu.disconf.client.addons.properties.ReloadingPropertyPlaceholderConfigurer"> <property name="ignoreResourceNotFound" value="true" /> <property name="ignoreUnresolvablePlaceholders" value="true" /> <property name="propertiesArray"> <list> <ref bean="configproperties_disconf"/> </list> </property> </bean> <!-- 使用托管方式的disconf配置(无代码侵入, 配置更改不会自动reload)--> <bean id="configproperties_no_reloadable_disconf" class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean"> <property name="locations"> <list> <value>redis.properties</value> <value>jdbc.properties</value> </list> </property> </bean> <bean id="propertyConfigurerForProject1" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="ignoreResourceNotFound" value="true"/> <property name="ignoreUnresolvablePlaceholders" value="true"/> <property name="propertiesArray"> <list> <ref bean="configproperties_no_reloadable_disconf"/> </list> </property> </bean> </beans>
其中 config.properties 实现了热加载, jdbc.properties和redis.properties只实现同步,需要重启加载。
当我们在disconf管理端,任意修改一个config.properties的属性,就会在控制台打印出相应信息,如:
INFO [main-EventThread] ReloadingPropertyPlaceholderConfigurer.propertiesReloaded(155) | Property changed detected: gtw.route.socket.timeout=8000 INFO [main-EventThread] ReloadingPropertyPlaceholderConfigurer.propertiesReloaded(227) | Updating property routeService.socketTimeout to 8000
