spring 云配置启动时克隆 http.postBuffer 问题

Question

我在使用 bitbucket url 启动 spring 云配置服务器时遇到问题 Integer value http.postbuffer out of range。

application.yml

server:
    port: 8888

spring:
    application:
        name: CONFIGSERVER
    cloud:
     config:
        label: master
        server:
          git:
            clone-on-start: true
            uri: https://bitbucket.org/MyGitRepo/config_server_env_profiles.git
            username: <username>
            password: <password>

可能是什么问题和解决方案？

Answer 1

显然，在克隆时 org.eclipse.jgit 库使用系统配置的属性，其中之一属性是 http.postBuffer .

它尝试将值转换为整数，如果值太大（或太小）则失败并出现超出范围的错误。

我通过 $ git config --get http.postBuffer 验证了属性，它返回值 4572864000

我在 .gitconfig 文件中验证，它是全局值，所以我将值降低为 524288000

然后它就像魅力一样奏效。希望对面临同样问题的人有所帮助。

Answer 2

对我来说有用的是将全局配置设置为 1MB：

git config --global http.postBuffer 1024
