Mybatis批量更新报错com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException

批量更新数据,非常简单的一段代码,硬是报错,插入的数据也能显示出来

List<User> userlist = new ArrayList<User>();
userlist.add(new User(1, "qq", "123132", "eee"));
userlist.add(new User(2, "3333", "123132", "rrrr"));

int i = usermapper.updateData(userlist);
<!-- 批量更新 -->
<update id="updateData" parameterType="list">
<foreach collection="list" item="item" separator=";">
update useres
<set>
uname=#{item.uname},pwd=#{item.pwd},realname=#{item.realname}
</set>
where
id=#{item.id}
</foreach>
</update>

最终,解决了问题如果连续执行多条sql语句 需要在url的后面 补充一个allowMultiQueries=true 即可

<property name="url" value="jdbc:mysql://localhost:3306/test?allowMultiQueries=true" />
