Solve that maven cannot read the xml file: org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

Create a maven interface in the project, write the sql statement in the xml file, and an error occurs in the execution

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

The xml file is in the java directory

reason

This error is caused by maven's default loading mechanism

When maven loads, compile the .java type files in the java folder, and other types of files will not be loaded

solve

method one:

Copy the xml directly to the target file directory (this method is not used much)

Method Two:

Put xml directly in the resource directory (the directory structure is automatically generated by code, this method will change the file structure)

Method three:

Realized by configuration

（1）pom.xml

    <!-- Let maven load the xml file in the main.java directory --> 
    <build> 
        <resources> 
            <resource> 
                <directory>src/main/java</directory> 
                <!-- What type of file to load -- > 
                <includes> 
                    <include>**/*.xml</include> 
                </includes> 
                <filtering>false</filtering> 
            </resource> 
        </resources> 
    </build>

(2) project application.properties

Set the path where the xml file is located

# Configure the path of the mapper xml file 
mybatis-plus.mapper-locations=classpath:com/xxx/eduservice/mapper/xml/*.xml

Note: Both pom and properties need to be configured
