disconf

disconf.xml

1、xml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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.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.dds.rss.route" />
    </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, 配置更改会自动reload) -->
    <bean id="configproperties_disconf"
          class="com.baidu.disconf.client.addons.properties.ReloadablePropertiesFactoryBean">
        <property name="locations">
            <list>
                <!--多个动态配置配置在这里-->
                <value>classpath:version.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>

</beans>

2、应用属性配置

/**
 * 描述： ID 属性
 *
 * @author 01374806
 * @date 2018/10/2
 */
@DisconfFile(filename = "id.properties")
@Component
public class IdProperties {

    private Long datacenterId = 0L;

    @DisconfFileItem(name = "dds.rss.route.id.datacenterId", associateField = "datacenterId")
    public Long getDatacenterId() {
        return datacenterId;
    }

    public void setDatacenterId(Long datacenterId) {
        this.datacenterId = datacenterId;
    }
}

3、回调（消息通知配置）

@Slf4j
@Component
@DisconfUpdateService(confFileKeys = { "dispatch.properties" })
public class DispatchPropertiesCallback implements IDisconfUpdate {

    @Override
    public void reload() throws Exception {
        log.info("dispatch.properties 检测到更新");
    }

}
