环境：
SpringFramework：4.3.5.RELEASE
apollo-client：1.5.1
1.在项目的 resources/META-INF/ 目录下添加 app.properties 文件：
#Apollo配置id
app.id = phpdragon-demo
apollo.bootstrap.enabled = true
apollo.eagerLoad.enabled = true
apollo.cacheDir = /data/app_data/apollo_cache/
2. 新建 ApolloConfigurer 类，负责处理合并本地properties配置：

import com.alibaba.dubbo.common.utils.ConfigUtils;import com.ctrip.framework.apollo.Config;import com.ctrip.framework.apollo.ConfigService;import org.springframework.beans.BeansException;import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;import java.util.Properties;import java.util.Set;/** * 处理apollo配置 */public class ApolloConfigurer extends PropertyPlaceholderConfigurer { static final String[] NAMESPACES = {"PUBLIC", "REDIS", "ZOOKEEPER", "application"}; @Override protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props) throws BeansException { try { this.reloadProperties(props); } catch (Exception e) { e.printStackTrace(); logger.info("获取apollo配置失败"); } //设置到dubbo的上下里 ConfigUtils.addProperties(props); super.processProperties(beanFactoryToProcess, props); } private void reloadProperties(Properties props) { for (String namespace : NAMESPACES) { Config config = ConfigService.getConfig(namespace); Set<String> fieldNames = config.getPropertyNames(); for (String attributeName : fieldNames) { props.put(attributeName, config.getProperty(attributeName, "")); //设置到系统变量里 System.setProperty(attributeName, config.getProperty(attributeName, "")); } } } @Override protected String resolvePlaceholder(String placeholder, Properties props) { this.reloadProperties(props); return props.getProperty(placeholder); }} |
3.在 Spring 的配置xml文件中声明配置：

<bean class="com.phpdragon.config.ApolloConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> <property name="ignoreResourceNotFound" value="true"/> <property name="trimValues" value="true"/> <property name="locations"> <list> <value>classpath*:*.properties</value> <value>classpath*:properties/*.properties</value> </list> </property> <property name="fileEncoding" value="UTF-8"/></bean> |
4.编写配置类接收远程配置变量：
