原因

dao層報Invalid bound statement。無非就是一下錯誤

  1. mapper.xml的namespace要寫所映射接口的全稱類名。
  2. mapper.xml中的每個statement的id要和接口方法的方法名相同
  3. mapper.xml中定義的每個sql的parameterType要和接口方法的形參類型相同
  4. mapper.xml中定義的每個sql的resultType要和接口方法的返回值的類型相同
  5. mapper.xml要和對應的mapper接口在同一個包下 mapper.xml的命名規範遵守: 接口名+Mapper.xml

總結

坑一:

在Mapper層，它是需要加@Mapper註解的，但是網上又有人加@respository，兩個註解混起來了，其實是任選其一都可以的。一般都是使用@Mapper。但是如果在Mapper層中加了註解，在配置主類SpringBootMybatisApplication裏面就不需要@MapperScan(“com.example.demo.mapper”)掃描註解，在配置類里加掃描註解的意思是將這個包下所有的都註解成Mapper。

坑二:

使用STS創建的SpringBoot項目，其中配置文件默認的是application.properties，一般在這個文件裏面配置數據源。但是這個文件想要起作用，則必須在配置主類中加入@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})自動注入，否則該配置文件中的配置無效。會報出Failed
to configure a DataSource: ‘url’ attribute is not specified and no
embedded datasource could be configured.錯誤

坑三：

不寫成@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})自動注入，可以把把application.properties配置文件改爲application.yml（個人測試可行）。

坑四：

這個bug就是因爲mybatis的xml沒有被掃到 導致的
mybatis 在application.yml常用的配置

mybatis:

  config-location: classpath:mybatis-config.xml
  # 注意：對應實體類的路徑
  type-aliases-package: com.winter.model  
  #注意：一定要對應mapper映射xml文件的所在路徑
  mapper-locations: classpath*:/com.xx.auth.mapper/*Mapper.xml
