mybatis+springmvc+sqlite一個累心的問題:不在糾結
阿新 • • 發佈：2019-01-29
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 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: NYI org.sqlite.RS.getColumnClassName(RS.java:269)
因為網上關於SQLite的整合資料較少（什麼百度 谷歌，搜遍了，連mybatis官網的例子都看了），所以自己就折騰，大概有4天吧，每天看到這個錯誤，已經不煩了，已經到快吐了。
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版的我已經搞定，想著
SQLite應該類似，結果始終是報錯，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，結果只發現下面這句，於是把resultType型別改成 “Object”，結果還是報錯。
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 驅動，於是
http://www.findjar.com/index.x?query=sqlite
報錯不再是java.sql.SQLException: NYI，
換 parameterTypeMissMatch,這個把resultType型別改回去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。
修改自增後，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。
