测试：报告异常

AbstractHandlerExceptionResolver.java:194 |org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver |Resolved exception caused by handler execution: org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.guli.edu.mapper.CourseMapper.getCoursePublishVoById

问题分析

dao层编译后只有class文件，没有mapper.xml，因为maven工程在默认情况下src/main/java目录下的所有资源文件是不发布到target目录下的，

解决方案

1. 在pom中配置如下节点

<!-- 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. 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

3. 重新打包项目会发现target目录下出现了xml文件夹
