mybatis+mysql中一個標簽內寫兩條sql語句報錯

    <update id="bindStu">
        update edu_student set user_username=#{user_username} where stu_id = #{stu_id};
        update edu_user set stu_id=#{stu_id} where user_username=#{user_username};
    </update>

報錯如下

### Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL
syntax; check the manual that corresponds to your MySQL server version for the right
syntax to use near 'update edu_user set stu_id='2' where user_username='111'' at line 2

 經查閱資料后發現,mybatis+mysql時可以一個標簽內寫多條語句,只不過需要mybatis在連接mysql時在url處加上allowMultiQueries=true
如下,在末尾加上即可:

jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?
useSSL=false&useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
