MyBatis org.apache.ibatis.binding.BindingException

关于MyBatis org.apache.ibatis.binding.BindingException: Type class cn.xdl.entity.UserTB is not known to the MapperRegistry 异常解决

目录结构如下

Mapper代码如下（示例）：

package cn.xdl.dao;

import java.util.List;

import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Param;

import cn.xdl.entity.User;

public interface UserTBMapper {
	
	public void insert(User user);
	@Delete("delete usertb where id=#{id}")
	public void delete(@Param("id")int id);
	public void update(User user);
	public User findById(int id);
	public List<User> findAll();
}

测试类代码如下（示例）：

package cn.xdl.test;

import java.io.IOException;
import java.io.Reader;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import cn.xdl.dao.UserTBMapper;
import cn.xdl.entity.UserTB;

public class UserTBTest {
	@Test
	public void test() throws IOException{
		SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();
		Reader reader = Resources.getResourceAsReader("sqlmap-config.xml");
		SqlSessionFactory factory = builder.build(reader);
		SqlSession session = factory.openSession();
		UserTB userDao = session.getMapper(UserTB.class);
		/*userDao.delete(1003);
		session.commit();*/
		System.out.println(session);

		
	}
}

总结

结果检查发现在测试类中在第22行中有问题

更改后问题解决
