摘要：
三表关联查询报告错误，但单个表未报告错误。以前写过一次，但后来发现了问题。结果发现insert语句有更多的半括号“（”问题检查了很长时间…错误消息如下org.springframework.beans.factory.UnsatisfiedDependencyException:ErrorCreatingbean，名称为'videoController'：UnsatisifiedDependency
三表关联查询报错, 单表不报错, 之前写过一遍没报错,后来查出问题所在了,原来是insert语句多写了半格括号"("
这个问题查了很久很久...
报错信息如下

后来发现只要在application.properties中注释掉#mybatis.mapper-locations=classpath:mapper/*.xml就好了, 以前也不用注释掉, 暂时先这样处理吧
#使⽤用阿⾥里里巴巴druid数据源，默认使⽤用⾃自带的 #spring.datasource.type =com.alibaba.druid.pool.DruidDataSource #开启控制台打印sql mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl # mybatis 下划线转驼峰配置,两者都可以 #mybatis.configuration.mapUnderscoreToCamelCase=true mybatis.configuration.map-underscore-to-camel-case=true #配置扫描[内路径下的mapper文件夹] #mybatis.mapper-locations=classpath:mapper/*.xml #配置xml的结果别名 mybatis.type-aliases-package=ren.redface.xdclass_ssm02.domain
更改SQL语句之后可以正常配置了
