我有這樣的:問題與「iBatis的」,錯誤設置爲null參數
public interface PermessiMapper {
final String SELECT_PERMESSI = "SELECT PR.CODICE as CODICE, PR.DESCRIZIONE as DESCRIZIONE FROM PERMISSION PR INNER JOIN USER_PERMISSION UP ON PR.CODICE=UP.PERMESSO INNER JOIN USERS US ON US.NOME_UTENTE=UP.UTENTE WHERE US.NOME_UTENTE = #{user} AND US.PASSWORD = #{password}";
@Select(SELECT_PERMESSI)
@Results(value = {
@Result(property="codice", column="CODICE"),
@Result(property="descrizione", column="DESCRIZIONE")})
public ArrayList<PermessoDTO> getPermessi(String user, String password);
}
的問題是,當我試圖執行查詢,它給了我這個錯誤:
### Error querying database. Cause: org.apache.ibatis.type.TypeException: Error setting null parameter. Most JDBC drivers require that the JdbcType must be specified for all nullable parameters. Cause: java.sql.SQLException: invalid column name
### The error may involve it.reply.ratingGateway.monitoringManagement.DB.PermessiMapper.getPermessi-Inline
### The error occurred while setting parameters
### Cause: org.apache.ibatis.type.TypeException: Error setting null parameter. Most JDBC drivers require that the JdbcType must be specified for all nullable parameters. Cause: java.sql.SQLException: Tipo di colonna non valido
我試圖改變#{name}
和#{password}
像一個簡單的字符串,如'xxx'和'yyy',然後它工作得很好。
我也可以說調試代碼,我看到我傳遞的兩個參數都不是null。
任何想法?
