springboot本地配置覆盖apollo配置

1.apollo包的版本(2.0.0)

<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo-client</artifactId>
    <version>2.0.0</version>
</dependency>
<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo-core</artifactId>
    <version>2.0.0</version>
</dependency>

2.apollo配置的优先级源码解析

主要是两个文件：com.ctrip.framework.apollo.spring.boot.ApolloApplicationContextInitializer和com.ctrip.framework.apollo.spring.config.PropertySourcesProcessor

(1)ApolloApplicationContextInitializer.class

会将apollo配置放到environment的first，如下代码environment.getPropertySources().addFirst(composite):

@Override
  public void initialize(ConfigurableApplicationContext context) {
    ConfigurableEnvironment environment = context.getEnvironment();

    if (!environment.getProperty(PropertySourcesConstants.APOLLO_BOOTSTRAP_ENABLED, Boolean.class, false)) {
      logger.debug("Apollo bootstrap config is not enabled for context {}, see property: ${
  
  {}}", context, PropertySourcesConstants.APOLLO_BOOTSTRAP_ENABLED);
      return;
    }
    logger.debug("Apollo bootstrap config is enabled for context {}", context);

    initialize(environment);
  }
