問題一：

Creating a new SqlSession
SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@1e0721ac] was not registered for synchronization because synchronization is not active
JDBC Connection [com.mysql.cj.jdbc.ConnectionImpl@196918e2] will not be managed by Spring

產生緣由：沒有配置事物控制

解決辦法：在啓動類中添加@EnableTransactionManagement 和實現類中添加@Transactional 聲明事務就能夠了，

問題二：NoSuchMethodException: tk.mybatis.mapper.provider.base.BaseInsertProvider.<init>()

產生緣由：緣由是你集成使用tk.mybatis 的包，dao接口中導入的都是k.mybatis有關的包，而Application 啓動類中@MapperScan註解導入的包是org.mybatis.spring.annotation.MapperScan。形成k.mybatis這個包中初始化失敗

解決辦法：Application 啓動類中@MapperScan註解導包使用 import tk.mybatis.spring.annotation.MapperScan; 這個包掃描Mapper接口

問題三：使用@Slf4j註解中 log 報錯

產生緣由：可能你使用的開發工具沒有集成lombok.jar

解決辦法：複製你項目中依賴lombok.jar 這個版本的jar。這裏以eclipse爲例：

把這個lombok.jar複製到你eclipse平級目錄中，而後在eclipse.ini加上 -javaagent:D:\eclipse-jee-2019-06\lombok.jar ，從新打開eclipse便可
