SSM日常报错

mybatis配置时出现org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)

 解决方法：

pom.xml添加:

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