Question

你好今天我使用Mybatis插入Arraylist有问题，如下面的代码：

@Insert("<script>"
            + "   <foreach collection='USER_LIST' item='User' separator=';'> "
            + "      insert into tbl_user(username,role) values(#{User.username},#{User.role})"
            + "  </foreach>"
            + "</script>")

当我插入单项arraylist时，它工作。但如果我在arraylist错误中有多个项目：

 insert into tbl_user(username,role)             values(?,?);   ;        values(?,?);

来自异常，＆＃34;错误的SQL语法[];嵌套异常是＆＃34;，我在你的代码中发现了这一点＆＃34; separator =＆＃39 ;;＆＃39;＆gt;＆＃34;，没错，myBatis不允许你写'＆＃39 ;;＆＃39 ;

如何在MyBatis中插入Arraylist？
