配置存储
springCloudConfig是使用EnvironmentRepository来存储服务器的配置数据的，返回Environment对象
public Environment(@JsonProperty("name") String name,@JsonProperty("profiles") String[] profiles,@JsonProperty("label") String label, @JsonProperty("version") String version,@JsonProperty("state") String state) {super();this.name = name;this.profiles = profiles;this.label = label;this.version = version;this.state = state;}
基于本地文件
如果存储是基于文件的，即配置了spring.cloud.config.server.native.searchLocation，此时使用的是NativeEnvironmentRepository来查找配置
使用本地文件的前提是要配置spring.prifiles.active=native
@Configuration(proxyBeanMethods = false)
@Profile("native")
class NativeRepositoryConfiguration {@Beanpublic NativeEnvironmentRepository nativeEnvironmentRepository(NativeEnvironmentRepositoryFactory factory,NativeEnvironmentProperties environmentProperties) {return factory.build(environmentProperties);}}
只有配置了spring.prifiles.active=native才会创建NativeEnvironmentRepository这个bean
基于Git
如果存储是基于git的，即配置了spring.cloud.config.server.git.uri，此时使用的是JGitEnvironmentRepository来查找配置
if (getUri().startsWith(FILE_URI_PREFIX)) {return copyFromLocalRepository();
}
else {return cloneToBasedir();
}
如果使用file:前缀来进行设置的，此时是从本地Git仓库获取的，也就不需要克隆
private Git copyFromLocalRepository() throws IOException {Git git;File remote = new UrlResource(StringUtils.cleanPath(getUri())).getFile();Assert.state(remote.isDirectory(), "No directory at " + getUri());File gitDir = new File(remote, ".git");Assert.state(gitDir.exists(), "No .git at " + getUri());Assert.state(gitDir.isDirectory(), "No .git directory at " + getUri());git = this.gitFactory.getGitByOpen(remote);return git;
}
如果不是用file前缀来进行设置的，就需要从git库去进行clone
private Git cloneToBasedir() throws GitAPIException {CloneCommand clone = this.gitFactory.getCloneCommandByCloneRepository().setURI(getUri()).setDirectory(getBasedir());configureCommand(clone);try {return clone.call();}catch (GitAPIException e) {this.logger.warn("Error occured cloning to base directory.", e);deleteBaseDirIfExists();throw e;}
}
