错误原因

导致原因:org . spring framework . beans . factory . unsatisfieddependencyexception:创建名为“userServiceimpl”的bean时出错:通过字段“userMapper”表示的未满足的依赖关系；嵌套异常为org . spring framework . beans . factory . unsatisfieddependencyexception:创建在文件[E:\ javacode \ spring MVC 006-SSM \ target \ classes \ com \ Pei HJ \ Mapper \ userMapper . class]中定义的名为“user Mapper”的bean时出错:通过bean属性“sqlSessionFactory”表示的不满足的依赖关系；嵌套异常为org . spring framework . beans . factory . nouniquebeandidefinitionexception:没有“org .

翻译过来如下是因为创建了两个javabean，属于配置文件application_service出错

是因为我在application_mapper中创建时已经通过sqlsessionfactorybean ，一个合格的sqlsessionfactory”类型的合格bean可用:应为单个匹配bean，但找到了2个:org . mybatis . spring . sqlsessionfactorybean # 0，org . mybatis . spring . sqlsessionfactorybean，因为我在配置service时候，配置数据源的时候datasource爆红,所以我进行了引用
