*  问题描述：在使用mybatis-plus框架开发时，使用mapper.xml文件写sql语句查询数据时，出现如上错误。
 *  解决思考：
    
     *  分析：在上述报错信息中，我们关注下面这句信息
        
            org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.atguigu.eduservice.mapper.EduCourseMapper.getPublishCourseInfo

BindingException：绑定异常（字面意思）  
(not found)：没有找到  
最后是一个方法名，也就是我们测试的方法

1.  首先我们仔细查看名字（方法名、类名等），或者单词拼写有没有错误
2.  反复检查，确认没有拼写不一致的错误之类的问题
3.  后面通过查看target编译之后的目录发现，mapper中的xml目录不见了，这是由于maven加载时，java类型地 文件进行编译，非.java文件不会加载

编译后：

*  **解决方法**：

1.  赋值xml文件夹到target中
2.  把xml文件夹放到resource中
3.  通过配置实现（推荐）
    
     *  pom.xml

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

*  application.propertities:在Spring Boot配置文件中添加配置
    
        #配置mapper xml文件的路径
          mybatis-plus.mapper-locations=classpath:com/guli/edu/mapper/xml/*.xml
