springcloud config Server报 Could not fetch remote for master remote:错误

今天在idea练习做springcloud config server的时候，地址栏输入http://localhost:8080/order-dev.yml，一直每办法出来xml格式的文件，前台报错如下，后台报错 Could not fetch remote for master remote::

找了好久没有找到问题，而且控制台不报错，后面改变了控制台日志打印级别。yml中添加如下

logging:
  level:
    com.netflix.discovery: 'OFF'
    org.springframework.cloud: 'DEBUG'

如下图:

控制台报如下错：

然后顺藤摸瓜，找到了，原来是git的设置问题。

• 原因：git配置的问题，http.postbuffer设置过大，导致Integer value http.postbuffer out of range,但是spring cloud默认没有clone-on-start参数的时候，console里面只显示Could not fetch remote for dev remote信息
• 解决方法: 设置git的http.postbuffer为适当值，参考配置：
  git config --get http.postBuffer
git config --global http.postBuffer 524288000

这里的git，是本地电脑安装的git。桌面右击git bash here，然后输入如下的命令：

git config --get http.postBuffer
git config --global http.postBuffer 524288000

再次运行，就能成功输出order-dev.yml的内容了。
