关于mapper接口与mapper.xml文件在同包运行找不到问题解决

springboot中解决方案一：

将mapper映射文件放到resources下，必须与mapper接口相同结构，并且在主启动类添加@MapperScan("com.offcn.mapper")注解扫描包

 

 

 

解决方案二：

直接在pom.xml中配置插件

<!--将java目录下的.xml/.properties文件复制到resources目录下-->

<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>
