Java之MyBatis 批量插入数据，两种方式（注解，XML）

Posted 2022-03-01 北芳科技

1、MyBatis之 XML 批量插入数据

int insertStudentList(List<SysStudent> sysStudent);

 <insert id="insertStudentList">
        insert into sys_student(sut_id, stu_name, stu_year) values
        <foreach item="item" index="index" collection="list" separator=",">
            (#item.sutId,#item.stuName,#item.stuYear)
        </foreach>
</insert>

2、MyBatis之 注解 插入数据

public interface SysStudentMapper extends Mapper<SysStudent> 

    public String tableName = "sys_student";
    public String columnNoId = "sut_id,stu_name,stu_year,;

    @Insert("<script> " +
            "insert into " + tableName +
            "(" + columnNoId + ") " +
            "values " +
            "<foreach collection=\\"items\\" index=\\"index\\" item=\\"item\\" separator=\\",\\"> "
            +
            "(#item.sutId,#item.stuName,#item.stuYear)"
            +
            "</foreach> " +
            "</script>")
    int batchSave(@Param("items") List<SysStudent> items);
