server.xml 里面配置了1

表user_info配置了主键自增，schema.xml 中配置了

一直报上面的错误，希望给予指导

走了一些debug的流程，代码有点多，而且貌似跟8.3的方法有重叠交叉的部分，比较困惑

这个问题我也遇到了，找了好久，后面发现是 UnsupportedEncodingException 这个异常，连蒙带猜的，修改了

<dataHost name="shard1" maxCon="1000" minCon="10" balance="1" writeType="0" dbType="mysql" dbDriver="native" switchType="-1" slaveThreshold="100">

把dbDriver="jdbc" 改成 dbDriver="native" 居然正常了，

mysql> select last_insert_id();
+------------------+
| LAST_INSERT_ID() |
+------------------+
| 105 |
+------------------+
1 row in set (0.00 sec)

神奇的mycat，坑太多了
