When using LambdaQueryWrapper, an error occurs: Invalid bound statement (not found): com.studentos.mapper.UserMapper.insert

1. Problem

使用LambdaQueryWrapper 报错org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.studentos.mapper.UserMapper.insert

(Translation: SQL statement binding error (not found) occurred when using LambdaQueryWrapper)

2. Screenshot display of the problem

3. Solution ideas

				第一种：mapper.xml中的namespace和实际的mapper文件不一致
				第二种：mapper接口中的方法名和mapper.xml中的id标签不一致
				第三种：Mapper.xml没有构建进去
				第四种：配置文件导不出来
				第五种：依赖没有配置正确

4. Problems arising from the project

The dependency was not imported, resulting in a SQL binding error (not found) when using LambdaQueryWrapper.
I have been stuck here for a while, hahaha. I accidentally saw a dependency on the mybatis official website one night, and suddenly I got the idea. . . Just add the dependency coordinates to the pom.xml configuration file. . .

 		<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.2</version>
        </dependency>

Let’s transplant hair together!
