一次，两次，三次都是一样的错误，总是没认识到严重，今天搭建app项目平台(其实就是拷贝一份老项目改吧改吧)又报错了，这回憋着劲儿改，找到问题才发现跟之前的原因还不一样。

 

环境：spring，springMVC，mybatis，dubbo。

 

项目之间各种依赖关系，总的来说，我遇到的情况一共有一下几种：

1、项目之间的依赖打包问题，依赖没有按照顺序打包安装

2、service的重复引用，循环引用，这种的遇到过两回，在aService引用了IAService的接口方法

3、第三种也就是我今天遇到的，项目中明明没有出现video相关的任何接口调用，但是启动报错就是跟video干上了，找了一圈加美女同事提醒才明白过来(百年老榆木脑袋)，项目依赖的service中用到了video相关的接口，项目中必须引入。反正就是报错了，一定有地方用到了，引入或者找到干掉就是了。

4、注入问题，常用的@Autowired默认按类型装配，默认情况下必须要求依赖对象必须存在，这个其实导致这种错误的可能性不大；主要是用了@Resource（这个注解属于J2EE的），它默认按照名称进行装配，对应比如说@Service("abcService")的abcService。这种的如果你的@servie上没有指定名称的话，用@AutoWired会比较容易避免出现这种问题。

 

总结如上，表述可能会有错误的地方，仅做工作记录，参考价值不大，遇到同样问题，仅供参考，欢迎各位大牛纠错！
