mybatis: No enum constant org.apache.ibatis.type.JdbcType."VARCHAR"

mybatis 插入的時候一句sql報錯如下。

 

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.builder.BuilderException: Error resolving JdbcType. Cause: java.lang.IllegalArgumentException: No enum constant org.apache.ibatis.type.JdbcType."VARCHAR"

 

insert into sys_user(
             <if test="userId != null and userId != '' ">user_id,</if>
           

             create_time
         )values(
             <if test="userId != null and userId != ''">#{userId,jdbcType="VARCHAR"},</if>
             
             sysdate
         )

原因在於

#{userId,jdbcType="VARCHAR"}, 

即mybatis所定義的類型常量枚舉不存在，mybatis 解析為了"VARCHAR" 帶雙引號的字符串，改為

insert into sys_user(
             <if test="userId != null and userId != '' ">user_id,</if>
         

             create_time
         )values(
             <if test="userId != null and userId != ''">#{userId,jdbcType=VARCHAR},</if>
         
             sysdate
         )

把雙引號去掉或者直接不寫jdbcType 即可。
