自己有个父工程，renren-security作为了一个子模块引入的自己项目。 代码生成器模板引入的common包依赖都改为了io.renren.common模块，生成的代码复制到自己父工程下新建的的子模块项目中，生成的代码相关的common包的依赖引入的io.renren模块，解决了依赖问题 [pre] <dependency> <groupId>io.renren</groupId> <artifactId>renren-admin</artifactId> <version>5.0.0</version> <scope>compile</scope> </dependency> [/pre] 然后自己没有写任何其它代码，直接启动这个子项目项目。 （问题一）（已解决，没有加swagger2依赖问题） 开头打印了人人的相关信息输出，然后接着报错，如下 [pre] org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'springfox.documentation.schema.TypeNameExtractor' available: expected at least 1 bean which qualifies as autowire candidate.

代码生成器生成代码插入自己的模块中，maven依赖引入renren-admin模块，解决了依赖问题，但是每次自己子模块启动都会导致renren-admin启动，然后爆出一些莫名其妙的错误。 之前没有修改模板生成的引入是自己的父类包下的common，自己没有这个模块，一大堆包引入报错爆红问题，所以做出了修改。 在这之前的之前，自己还手动抽取过相关的common包下的公共类，来作为自己的子模块生成器生成的代码所需的包引入，但是总是依赖出问题，依赖理不清楚。
