[ { "del": [ {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"} ] }, { "asd": [ {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"}, {"code": 1, "name": "zhangsan"} ] } ]

这段代码是一个包含两个元素的列表，每个元素都是一个字典。第一个字典的键为"del"，值为一个包含4个字典元素的列表，每个字典元素都包含一个"code"键和一个"name"键，表示删除操作的相关信息。第二个字典的键为"asd"，值为一个包含4个字典元素的列表，每个字典元素也都包含一个"code"键和一个"name"键，但是这里的字典元素表示不同的操作。整个数据结构使用了列表和字典的嵌套组合，用于表示一些复杂的数据结构或者数据流程。

[ "del":[ {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"} ] ,"del":[ {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"}, {"code":1,"name":"zhangsan"} ] ]

这个JSON格式不太符合规范，因为键名不能重复。如果您想要表示两个不同的数组，可以使用不同的键名，比如这样：

{
  "del1": [
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"}
  ],
  "del2": [
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"},
    {"code": 1, "name": "zhangsan"}
  ]
}

这个JSON格式包含了两个数组，分别使用了键名 "del1" 和 "del2"。您可以根据需要修改键名和数组内容。

[{teacherId:001,TeacherName:zhangsan,StudentId:001,StudentName:lisi},{teacherId:001,TeacherName:zhangsan,StudentId:002,StudentName:wangwu}]怎么使用mubatis将上边对象插入老师表和学生表

假设老师表的表名为`teacher_table`，包含`teacher_id`和`teacher_name`两个字段，学生表的表名为`student_table`，包含`student_id`和`student_name`两个字段。

首先，需要定义对应的实体类，以及对应的Mapper接口。这里简化为：

Teacher.java

public class Teacher {
    private int teacherId;
    private String teacherName;
    // getter and setter
}

Student.java

public class Student {
    private int studentId;
    private String studentName;
    // getter and setter
}

TeacherMapper.java

public interface TeacherMapper {
    void insertTeacher(Teacher teacher);
}

StudentMapper.java

public interface StudentMapper {
    void insertStudent(Student student);
}

然后，在MyBatis的配置文件中，定义对应的SQL语句，以及参数的映射。这里可以使用MyBatis的foreach标签，将对象列表中的每个对象都插入到对应的表中。

例如，定义插入老师表的SQL语句：

<insert id="insertTeacher" parameterType="com.example.Teacher">
    insert into teacher_table(teacher_id, teacher_name)
    values
    <foreach collection="list" item="teacher" separator=",">
        (#{teacher.teacherId}, #{teacher.teacherName})
    </foreach>
</insert>

定义插入学生表的SQL语句：

<insert id="insertStudent" parameterType="com.example.Student">
    insert into student_table(student_id, student_name)
    values
    <foreach collection="list" item="student" separator=",">
        (#{student.studentId}, #{student.studentName})
    </foreach>
</insert>

最后，在Java代码中，调用Mapper接口的方法即可。假设Mapper接口的实现类为`TeacherMapperImpl`和`StudentMapperImpl`，示例代码如下：

List<Map<String, String>> list = new ArrayList<>();
Map<String, String> map1 = new HashMap<>();
map1.put("teacherId", "001");
map1.put("teacherName", "zhangsan");
map1.put("studentId", "001");
map1.put("studentName", "lisi");
list.add(map1);

Map<String, String> map2 = new HashMap<>();
map2.put("teacherId", "001");
map2.put("teacherName", "zhangsan");
map2.put("studentId", "002");
map2.put("studentName", "wangwu");
list.add(map2);

SqlSession sqlSession = MybatisUtils.getSqlSession();
TeacherMapper teacherMapper = sqlSession.getMapper(TeacherMapper.class);
StudentMapper studentMapper = sqlSession.getMapper(StudentMapper.class);

List<Teacher> teachers = new ArrayList<>();
List<Student> students = new ArrayList<>();

for (Map<String, String> map : list) {
    Teacher teacher = new Teacher();
    teacher.setTeacherId(Integer.parseInt(map.get("teacherId")));
    teacher.setTeacherName(map.get("teacherName"));
    teachers.add(teacher);

    Student student = new Student();
    student.setStudentId(Integer.parseInt(map.get("studentId")));
    student.setStudentName(map.get("studentName"));
    students.add(student);
}

teacherMapper.insertTeacher(teachers);
studentMapper.insertStudent(students);

sqlSession.commit();
sqlSession.close();

以上代码中，首先将原始的列表转换为`Teacher`和`Student`对象的列表，然后调用对应的Mapper接口方法，将数据插入到数据库中。

需要注意的是，这里示例代码中使用了MyBatis的工具类`MybatisUtils`来获取SqlSession对象。此外，还需要在MyBatis的配置文件中，定义对应的数据源和Mapper接口扫描路径。
