报错原因:

编译前mapper中有xml文件:

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.atguigu.eduservice.mapper.EduCourseMapper.getPublishCourseInfo

 

 

 

编译后mapper中没有xml文件:

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.atguigu.eduservice.mapper.EduCourseMapper.getPublishCourseInfo

 

当项目中创建mapper接口,编写xml文件SQL语句时候找不到文件,就会报.binding.BindingException:绑定异常错误,这个错误是maven默认加载机制造成的。

解决方式:

1、复制xml到target目录中

2、把xml文件放到resources目录中

3、推荐使用:通过配置实现

(1)pom.xml

<!-- 项目打包时会将java目录中的*.xml文件也进行打包 -->
<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

 

(2)项目application.properties

 

#配置mapper xml文件的路径
mybatis-plus.mapper-locations=classpath:com/guli/edu/mapper/xml/*.xml
