1 java.sql.SQLException: NYI

2 org.sqlite.RS.getColumnClassName(RS.java:269)

在配置mybatis+springmvc+sqlite時候，

<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 不會自動加1，所以手動了               </selectKey>                            insert into t_demo (id,name,age,sex)values(#{id},#{name},#{age},#{sex})    </insert>

遭遇到一下問題:

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: NYIorg.sqlite.RS.getColumnClassName(RS.java:269)

因?yàn)榫W(wǎng)上關(guān)于SQLite的整合資料較少（什么百度 谷歌，搜遍了，連mybatis官網(wǎng)的例子都看了），所以自己就折騰，大概有4天吧，每天看到這個錯誤，已經(jīng)不煩了，已經(jīng)到快吐了。

在配置mybatis的mapper.xml中需要配置 insert語句，而ID自增是最大的問題，PostgreSQL版的我已經(jīng)搞定，想著

SQLite應(yīng)該類似，結(jié)果始終是報錯，具體:

快心死的時候，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，結(jié)果只發(fā)現(xiàn)下面這句，于是把resultType類型改成 “Object”，結(jié)果還是報錯。

  public String getColumnClassName(int col) throws SQLException {        checkCol(col);        return "java.lang.Object";    }

絕望了，不過 突然想到 要不要去 findjar.com上找個新的SQLite-jdbc 驅(qū)動，于是

http://www.findjar.com/index.x?query=sqlite

找到了最新版本“sqlite-jdbc-3.6.14.1.jar” 結(jié)果令人驚喜的事發(fā)生了，

報錯不再是java.sql.SQLException: NYI，

換 parameterTypeMissMatch,這個把resultType類型改回去int，再跑,以為會ok，

出人意料的是，又報錯，不過這個錯我是知道的，sql主鍵唯一的錯誤，原來SQLite的ID自增是假的，就不自增，只是記錄而已，要自己手動加。

修改自增后，測試沒有問題了。

一個字，心累，share防止有同樣問題的人在此糾結(jié)。
