Question

在spring cloud配置服务器克隆git repo并正确提供文件之后，它是否也可以对这些文件进行更改并将它们推回到远程git repo？或者是否必须在运行配置服务器的应用程序中编写该功能？

Answer 1

不，它不能写。 Config Server是远程git存储库的只读客户端。

对于其他感兴趣的人，我自动安装了Spring JGitEnvironmentRepository并包含了一些额外的功能。我使用FileUtils来处理文件操作，然后使用该JGit bean编写了一个基本服务：

@Autowired private JGitEnvironmentRepository jgit;

@Value("${spring.cloud.config.server.git.uri}.git")
private String remoteRepoURL;

@Value("${spring.cloud.config.server.git.username}")
private String username;

@Value("${spring.cloud.config.server.git.password}")
private String password;

private Git git = null;
private Repository localRepo ;
private CredentialsProvider creds;

public File getWorkingDirectory(){
    return jgit.getBasedir();
}

public void updateLocalRepo() throws Exception {
    log.info("Updating the local repository.");
    init();
    git.pull()
        .setCredentialsProvider( creds )
        .call();
}

public void commitAndPushRepository(String commitMessage) throws Exception {
    init();
    git.commit()
        .setAll(true)
        .setMessage(commitMessage)
        .call();

    git.push()
        .setCredentialsProvider( creds )
        .call();

    log.info("Pushed local repository with message [" + commitMessage+"].");
}//end commitAndPush

private void init() throws IOException {
    if(git!=null) return;

    String repoPath = jgit.getBasedir().getPath();
    localRepo = new FileRepository(repoPath + "/.git");
    git = new Git(localRepo);
    StoredConfig config = git.getRepository().getConfig();
    config.setString("remote", "origin", "url", remoteRepoURL);
    config.save();
    creds = new UsernamePasswordCredentialsProvider(username, password);
    log.info("Initialized local repository at path " + repoPath);
}

这是文件服务：

@Autowired private GitService gitService;

public void updateFile(String author, String fileName, String newContent) throws Exception{
    Assert.hasLength(fileName, "File name must not be null.");
    Assert.hasLength(newContent, "File must contain content.");
    Assert.hasLength(author, "Unable to update file without author logging.");

    gitService.updateLocalRepo();

    File workingDirectory = gitService.getWorkingDirectory();

    log.info("Updating file [" + fileName + "] in the working dir " + workingDirectory);

    File matchingFile = findFileWithName(workingDirectory, fileName);
    Assert.notNull(matchingFile, "No file with name " + fileName + " was found.");

    FileUtils.write(matchingFile, newContent);
    gitService.commitAndPushRepository( buildCommitMessage(author, fileName) );
}//end updateFile

public String getConfigFileContents(String fileName) throws Exception {
    gitService.updateLocalRepo();
    File file = findFileWithName(gitService.getWorkingDirectory(), fileName);
    Assert.notNull(file, "No file with name " + fileName + " found.");
    return FileUtils.readFileToString( file );
}

public Collection<String> getAllConfigFileNames() throws Exception{
    gitService.updateLocalRepo();
    Collection<String> fileNames = new ArrayList<>();
    Collection<File> allFiles = FileUtils.listFiles(gitService.getWorkingDirectory(), TrueFileFilter.INSTANCE, TrueFileFilter.INSTANCE);
    for(File file : allFiles) {
        fileNames.add(file.getName());
    }//end foreach file

    return fileNames;
}

private String buildCommitMessage(String author, String fileName) {
    return "Author of commit on [" + fileName + "]: " + author;
}

private File findFileWithName(File workingDirectory, String fileName) {
    Collection<File> allFiles = FileUtils.listFiles(workingDirectory, TrueFileFilter.INSTANCE, TrueFileFilter.INSTANCE);
    for(File file : allFiles) {
        if(fileName.equals(file.getName())){
            return file;
        }//endif found
    }//end foreach file

    return null;
}//end findFileWIthName

Spring Cloud Config Server是否也可以将配置更新推送到远程git仓库？
