新老客户大回馈,云服务器低至5折

通过jgit一次性升级fastjson版本

背景:笔者所在公司经历了三次fastjson的升级,由于集群,工程数量众多,每次升级都很麻烦。因此开发了一个java的升级工具。
功能介绍:

功能介绍:一个jar文件,通过java -jar命令,输入用户名,密码,所负责的git项目主目录,即可对所负责的本地工作区目录下的项目工程中的pom.xml文件进行检测,然后对其依赖的低版本fastjson直接升级到最新版本。
pom依赖:

        return "";
    }
}

通过pom依赖和工具类构件maven jar

  1. 新建需要升级的项目工程的分支
  2. 构建升级jar包,放到项目空间目录中,与其他工程项目同级
  3. cmd打开命令行cd到项目空间目录中,执行命令
    java -jar \pomup.jar username password http://github.com/username/xxxx

说明:pomup.jar:构建的jar包名称
username,password :git的用户名,密码
http://github.com/username/xxxx:整体的git项目空间
