Invalid bound statement (not found)

springboot中mybatis报Invalid bound statement (not found)
解决方案
在pom中加入

                <excludes>
                    <exclude>**/*.java</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>
 <build>
