提问:这是什么情况引起,想保持list、page字符串命名,应该如何解决?
描述:最近在做项目升级从2.5.0升级到3.0.1,业务在2.5.0能完美运行。将业务模块代码迁移后发现请求报错,经过排查跟踪尝试,竟然发现与命名有关。
1. Mapper中的方法名为:list,在3.0.1中报错空指针异常,于是更改名字为listCommon,依然报错,于是不断尝试listTestCommon、testListCommon、commonTestList,这些都报错,并且包含list、List、page、Page这些字符串的方法名均报错。【图1】
2. 于是尝试其他不带有list、List、page、Page的名字,例如:getCommon、testCommon、getxxxTest。这些均能正常访问。
3. 经过排查和跟踪发现,异常出现位置:如图2

排查了一下午,我亲自来填坑。原因是因为启动类同时使用了这两个注解:
@EnableFeignClients({"com.xxx"})
@EnableBladeFeign
首先说一下之前为什么会加@EnableFeignClients,是因为原来2.5.0版本只需要加@EnableBladeFeign就可以了。
在3.0.1版本中并不能启动,需要EnableFeignClients添加包名才能启动,并且能启动成功,但遇到list、page方法会报错。【原因未知】
一直debug到源码最最最底层还是找不到问题所在,于是开始跳出代码层面,从最原始更改出寻找答案,找到启动类,看了两个注解发现竟然有包涵关系,于是把EnableFeignClients删除,并EnableBladeFeign指定包名,启动成功,并能正常访问。【具体原因还不清楚,有遇到的小伙伴给个留言】
