關於mapper接口與mapper.xml文件在同包運行找不到問題解決

springboot中解決方案一：

將mapper映射文件放到resources下，必須與mapper接口相同結構，並且在主啟動類添加@MapperScan("com.offcn.mapper")注解掃描包

 

 

 

解決方案二：

直接在pom.xml中配置插件

<!--將java目錄下的.xml/.properties文件復制到resources目錄下-->

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.*</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>

    </plugins>
