classpath*:**/mapping/*.xml不起作用的解决办法

接手了一个新项目,该项目的mybatis对应的mapper文件不是放在resources目录下的,是放在java目录下的,如图所示:

mybatis配置如下:

mybatis-plus.type-aliases-package=com.miaodi.channel.common.data.object
mybatis-plus.mapper-locations=classpath*:**/mapping/*.xml

运行报错,提示,

org.apache.ibatis.binding.BindingException: Invalid bound statement 

为哈会报错呢?原因是,猜测默认打包时 mybatis扫描不到 java目录下的classparh

解决办法,在pom文件中加入

 

<build>
        <resources>
            <resource>
                <directory>src/main/webapp</directory>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
    </build>

 体现的是约定大于配置的思想,当然是可以改的了,需要去pom.xml文件加上一段<build>代码,自行百度搜索,或者去B站看狂神说mybatis教程的第二个视频“第一个mybatis程序”的第52分钟,看看人家怎么解决这个问题
