postman请求一个action，接口里面配置了另外一个action接口http://localhost:8080本地接口,单独访问两个接口一切正常，嵌套调用就访问不通，检查了接口和地址都是正确的，debug断点不跳转
具体错误如下：
log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

前后端分离的项目不能嵌套调用action，访问地址都不一样呢。
maven项目不同模块的项目，两个action互调，配置的pom.xml是单向的，不能双向配置，也有大佬说一个action的接口放在业务层service里面。配置service获取，但是两个action都需要外部调用，不止是内调接口，所以都被否决了，大佬们发表一下建议！！
报错是访问不到localhost:12345，这个12345端口是怎么来？确认打开了吗？
问题找到了，启动服务debug打断点的原因，把断点放开了就能正常访问了，有可能是最开始访问不通，消息堵塞了，一直没重启服务，重启服务并且去掉断点就可以正常请求action接口了
