<>快速解决方案
* 查询class相对路径：jar tf test.jar | grep "test.class"
* 单独解压class文件：jar xvf test.jar com/test/test.class
* 查看class文件内容：javap -c com/test/test.class
<>背景
服务运行后，日志打印出来发现：字段丢失，定位查找问题，确认是否是服务器CLASS类与本地JAVA代码不一致。
<>1. 查找类目录
Linu命令 展开当前目录结构：tree
定位到类所在JAR包：
<>JAR命令的应用
以下为：JAR命令的基本使用
<>1. 过滤class路径
使用方式：jar tf test.jar | grep "test.class"
使用示例：jar tf hs-global-modelbff-api-1.0.9-SNAPSHOT.jar | grep
"UserBenefitDTO.class"
<>2. 解压JAR文件：
2.1 简单粗暴，直接解压整个JAR包：
使用方式：jar xvf test.jar
使用示例：jar xvf hs-global-modelbff-api-1.0.9-SNAPSHOT.jar
2.2 优雅精致，解压需要查看的类：
使用方式：jar xvf test.jar com/test/test.class
使用示例：jar xvf hs-global-modelbff-api-1.0.9-SNAPSHOT.jar
com/tpsjj/dto/user/UserBenefitDTO.class
注意：JAR包 跟 class 路径不能写反哦
<>3. 查看class文件内容
使用方式：javap -c com/test/test.class
使用示例：javap -c com/tpsjj/dto/user/UserBenefitDTO.class
