读取模版文件夹失败!

Error message

读取模版文件夹失败!

What it means

AutoCodePackage.Templates lists the code-generator template folders by reading the relative directory "resource" with os.ReadDir. When that read fails (directory missing, not a directory, or permission denied), the underlying error is wrapped with the message "读取模版文件夹失败!" and returned, so the frontend template picker gets no folder list.

Solutions

1. Start the server with its working directory set to the server root (where server/resource exists), e.g. cd server && ./gva, or fix the WorkingDirectory in the systemd/supervisor unit.
2. Verify the resource directory exists: ls ./resource; restore it from the repository if it was deleted.
3. Check directory permissions so the process user can read resource/.
4. If embedding/deploying differently, adjust the hard-coded "resource" path or run behind the documented launch script.

Example fix

// before (running from wrong cwd)
$ /opt/gva/server  # /opt/gva has no resource/
// after
$ cd /opt/gva/server && ./gva  # ./resource exists here

if info, err := os.Stat("resource"); err != nil || !info.IsDir() {
    return fmt.Errorf("resource/ 模板目录不存在于工作目录 %s", os.Getwd())
}

names, err := svc.Templates(ctx)
if err != nil {
    log.Printf("读取模板列表失败（检查工作目录下是否存在 resource/）: %v", err)
    return err
}

When it happens

Trigger: Calling GET the auto-code package templates API (s.autoCodePackage.Templates) when the process working directory does not contain a "resource" directory — e.g. the server binary is launched from a directory other than the repo/server root, or the resource folder was deleted or not deployed.

Common situations: Running the compiled server binary from / or a systemd unit with a wrong WorkingDirectory; Docker image missing server/resource; renaming or moving resource/; running tests from a package directory instead of the server root.
