IDEA mybatis入门程序UserTest测试错误

Question

我在测试UserTest,中间就出现几个断点

package Test;
import com.itheima.pojo.User;
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 java.io.IOException;
import java.io.Reader;
public class UserTest {   //这个地方测试错误！
    @Test
    public void userFindByIdTest() {   //这个地方测试错误！
        String resources = "mybatis-config.xml";
        //创建流
        Reader reader = null;
        try {
            //读取 mybatis-config.xml文件内容到reader对象中
            reader = Resources.getResourceAsReader(resources);
        } catch (IOException e) {
            e.printStackTrace();
        }
        //初始化MyBatis数据库，创建SqlSessionFactory类的实例
        SqlSessionFactory sqlMapper = new
                SqlSessionFactoryBuilder().build(reader);
        //创建SqlSession实例
        SqlSession session = sqlMapper.openSession();
        //传入参数查询，返回结果
        User user = session.selectOne(
                "findById", 1);
        //输出结果
        System.out.println(user.getUname());
        //关闭session
        session.close();
    }
}

这是原图

出现的问题

org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.sql.SQLNonTransientConnectionException: Cannot load connection class because of underlying exception: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near '=true '.
### The error may exist in com/itheima/mapper/UserMapper.xml
### The error may involve com.itheima.mapper.UserMapper.findById
### The error occurred while executing a query
### Cause: java.sql.SQLNonTransientConnectionException: Cannot load connection class because of underlying exception: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near '=true '.

我检查过其他的文件，没有爆红，问过别人，她说我的第一个问题

Public Key Retrieval is not allowed

而后我在db.properties中添加了allowPublicKeyRetrieval=true

mysql.driver=com.mysql.cj.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&\
      characterEncoding=utf8&useUnicode=true&useSSL=false allowPublicKeyRetrieval=true 
mysql.username=root
mysql.password=root

但是又出现了新问题

org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.sql.SQLNonTransientConnectionException: Cannot load connection class because of underlying exception: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the connection string near '=true '.

Answer 1

useSSL和allowPublicKeyRetrieval是两个参数，需要加&
