启动http时的spring云配置克隆。后缓冲区问题

Question

我得到了问题整数值http。使用bitbucket url启动spring云配置服务器时，postbuffer超出范围。

应用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>

问题和解决方案可能是什么？

Answer 1

在我的案例中，将全局配置设置为1MB有帮助：

git-config——全局http。后缓冲区1024

Answer 2

显然，在幕后，org.eclipse.jgit库，而克隆使用系统配置的属性，其中一个属性是http.postBuffer。

它尝试将值转换为整数，如果值太大（或太小），则会失败，并出现上述超出范围的错误。

我通过$git config--gethttp.postBuffer验证了属性，它返回了值4572864000

我核实过了。gitconfig文件，它是全局值，所以我将该值降低到524288000

然后它像魅力一样发挥作用。希望这能帮助面临同样问题的人。
