百度看到有说jar冲突的 受启发
查看pom文件 引入了两个公司的jar
<dependency>
<groupId>xx</groupId> <artifactId>xx-util</artifactId> <version>${xx.version}</version> </dependency> <dependency> <groupId>xx-arch</groupId> <artifactId>xx-okHttp</artifactId> <version>${xx.version}</version> </dependency>进入 上面那个jar A的pom 文件 发现 已经对下面那个jar B 进行了封装 重复了
3. 解决方案
去掉上面那个jar A， reboot ok了
