mybatis+springmvc+sqlite一个累心的问题:不在纠结
1 java.sql.SQLException: NYI
2 org.sqlite.RS.getColumnClassName(RS.java:269)
在配置mybatis+springmvc+sqlite时候，
<insert id="saveUser" parameterType="User" keyProperty="id" useGeneratedKeys="false" >
<selectKey keyProperty="id" resultType="int" order="BEFORE">
SELECT seq+1 as seq FROM sqlite_sequence WHERE (name = 't_demo') //sqlite 不会自动加1，所以手动了
</selectKey>
insert into t_demo (id,name,age,sex)values(#{id},#{name},#{age},#{sex})
</insert>
遭遇到一下问题:
1 root cause
org.springframework.jdbc.UncategorizedSQLException: Error selecting key or setting result to parameter object. Cause: java.sql.SQLException: NYI ; uncategorized SQLException for SQL []; SQL state [null]; error code [0]; NYI; nested exception is java.sql.SQLException: NYI
2 root cause
java.sql.SQLException: NYI org.sqlite.RS.getColumnClassName(RS.java:269)
因为网上关于SQLite的整合资料较少（什么百度 谷歌，搜遍了，连mybatis官网的例子都看了），所以自己就折腾，大概有4天吧，每天看到这个错误，已经不烦了，已经到快吐了。
在配置mybatis的mapper.xml中需要配置 insert语句，而ID自增是最大的问题，PostgreSQL版的我已经搞定，想着
SQLite应该类似，结果始终是报错，具体:

快心死的时候，都去
https://code.google.com/p/sqlite-jdbc/source/browse/src/main/java/org/sqlite/RS.java?r=e74939879270122b724d6fd62d8c40aa70870fcf
看了SQLite jdbc的source，结果只发现下面这句，于是把resultType类型改成 “Object”，结果还是报错。
public String getColumnClassName(int col) throws SQLException { checkCol(col); return "java.lang.Object"; }
绝望了，不过 突然想到 要不要去 findjar.com上找个新的SQLite-jdbc 驱动，于是
http://www.findjar.com/index.x?query=sqlite
找到了最新版本“ sqlite-jdbc-3.6.14.1.jar” 结果令人惊喜的事发生了，
报错不再是java.sql.SQLException: NYI，
换 parameterTypeMissMatch,这个把resultType类型改回去int，再跑,以为会ok，
出人意料的是，又报错，不过这个错我是知道的，sql主键唯一的错误，原来SQLite的ID自增是假的，就不自增，只是记录而已，要自己手动加。
修改自增后，测试没有问题了。
一个字，心累，share防止有同样问题的人在此纠结。
