不知道错在哪,我只写了一个application啊,尝试修改application的name也不行,还是会报多个application.求指点

Answer 1

配置了什么注解?我的项目几乎全是基于注解的.这两个application我只能找到一个,另一个实在找不到.我觉得是不存在另一个的.

Answer 2

 <dubbo:application name="file_service" id="file_service" /> and <dubbo:application name="file_service" id="file_service2" />

 这两个name重复了， 删除一个。 

或者是不是配置了注解？

Answer 3

没有了,就算有重名,那我修改这个application的name不就可以避免了?可是我修改什么name,都会报这个错误.懵逼,其余两个服务层都能正常运行,就这个file起不了,,,,

Answer 4

回复
是不是没有编译，还是读的之前的classes

Answer 5

回复
我应该是编译过了.rebuild了好几遍,我再试试吧

Answer 6

你搜一下这个，应该还有有两个application重名了

<dubbo:application name="file_service" id="file_service2" />
