解决Maven项目下使用Mybatis时，找不到mapper映射文件（不拷贝）问题

问题

控制台输出错误信息：

原因

从这里看出，mapper接口与mapper映射文件放在同一包下

但是编译后，classes下只有.class文件，而没有mapper映射文件，导致调用mapper接口时找不到映射文件

方法

修改pom.xml文件

<build>
    <plugins>
        
        <plugin>
            <groupId>org.apache.maven.pluginsgroupId>
            <artifactId>maven-resources-pluginartifactId>
            <version>2.7version>
            <configuration>
                <encoding>UTF-8encoding>
            configuration>
        plugin>
    plugins>
    <resources>
         <resource>
             <directory>src/main/javadirectory>
             <includes>
                 <include>**/*.propertiesinclude>
                 <include>**/*.xmlinclude>
             includes>
             <filtering>falsefiltering>
         resource>
     resources>
build>

结果
