1.如果映射文件和接口文件放在同一個文件夾下(沒在resource下),需要在pom中配置以下,不然映射失敗
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
2.映射文件和方法名保持一致
3.You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property)
JDBC版本過高,url要配置
spring.datasource.url=jdbc:mysql://localhost:3306/student?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
