今天在做mybatis的查詢時,報了一個奇葩錯:
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.lang.NumberFormatException: For input string: "y"
### Cause: java.lang.NumberFormatException: For input string: "y"
at org.mybatis.spring.MyBatisExceptionTranslator.translateExceptionIfPossible(MyBatisExceptionTranslator.java:79)
at org.mybatis.spring.SqlSessionTemplate$SqlSessionInterceptor.invoke(SqlSessionTemplate.java:447)
at com.sun.proxy.$Proxy219.selectList(Unknown Source)
at org.mybatis.spring.SqlSessionTemplate.selectList(SqlSessionTemplate.java:231)
at org.apache.ibatis.binding.MapperMethod.executeForMany(MapperMethod.java:128)
引起異常的代碼如下:
<if test="like == 'y'">
AND o.short_code LIKE CONCAT('%', #{shortCode}, '%')
</if>
經過網上查找,原來’y’被認為是char類型,'yy’或者“y”沒有問題。
如何解決?
- 将代碼改為 test=“like == ‘y’.toString()”
- 将代碼改為 test=“like == “y””
- 将代碼改為 test=‘like == “y”’
