Mybatis批量更新報錯com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException
批量更新資料,非常簡單的一段程式碼,硬是報錯,插入的資料也能顯示出來
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>

最終,解決了問題如果連續執行多條sql語句 需要在url的後面 補充一個allowMultiQueries=true 即可
<property name="url" value="jdbc:mysql://localhost:3306/test?allowMultiQueries=true" />
