[{teacherId:null,TeacherName:zhangsan,StudentId:001,StudentName:lisi},{teacherId:null,TeacherName:zhangsan,StudentId:002,StudentName:wangwu}]怎么使用mubatis将上边对象插入老师表获取插入id之后在学生表关联该id

可以使用MyBatis的一些特性来完成这个任务，以下是一种可能的解决方案：

1. 定义两个实体类：Teacher和Student，分别对应老师表和学生表。

public class Teacher {
    private Integer id;
    private String name;
    // getter and setter
}

public class Student {
    private Integer id;
    private String name;
    private Integer teacherId;
    // getter and setter
}

2. 定义两个Mapper接口：TeacherMapper和StudentMapper，分别对应老师表和学生表的操作。

public interface TeacherMapper {
    int insert(Teacher teacher);
    // 获取插入id
    @SelectKey(statement="SELECT LAST_INSERT_ID()", keyProperty="id", before=false, resultType=Integer.class)
    void insertAndGetId(Teacher teacher);
}

public interface StudentMapper {
    int insert(Student student);
}

3. 在XML文件中定义插入语句和关联语句。

<!-- 插入老师 -->
<insert id="insert" parameterType="Teacher">
    INSERT INTO teacher (name) VALUES (#{name})
</insert>

<!-- 插入老师并返回ID -->
<insert id="insertAndGetId" parameterType="Teacher">
    INSERT INTO teacher (name) VALUES (#{name})
</insert>

<!-- 插入学生 -->
<insert id="insert" parameterType="Student">
    INSERT INTO student (name, teacher_id) VALUES (#{name}, #{teacherId})
</insert>

4. 在Java代码中使用MyBatis进行操作。

// 创建一个SqlSessionFactory对象
SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);

// 创建一个SqlSession对象
try (SqlSession session = factory.openSession()) {
    // 获取TeacherMapper和StudentMapper对象
    TeacherMapper teacherMapper = session.getMapper(TeacherMapper.class);
    StudentMapper studentMapper = session.getMapper(StudentMapper.class);

    // 插入老师并获取ID
    Teacher teacher = new Teacher();
    teacher.setName("zhangsan");
    teacherMapper.insertAndGetId(teacher);
    Integer teacherId = teacher.getId();

    // 插入学生并关联老师ID
    Student student1 = new Student();
    student1.setName("lisi");
    student1.setTeacherId(teacherId);
    studentMapper.insert(student1);

    Student student2 = new Student();
    student2.setName("wangwu");
    student2.setTeacherId(teacherId);
    studentMapper.insert(student2);

    // 提交事务
    session.commit();
}

这样，就可以通过MyBatis将数据插入老师表并获取插入的ID，然后将学生表中的数据关联到老师表中的数据。
