私はSQLユーティリティクラスのCallableStatementを試していましたプロシージャはDBで正常に実行されていますが、配列インデックスの範囲外エラーが発生しましたデバッグしようとしましたが、callablestatementの構文に何か問題があるようです
public int CalableStatement(String query,Login login,String type) throws ClassNotFoundException, SQLException
{ int i =0;
try {
Connection con = getConnection();
//String q = query+"(?,?,?)";
CallableStatement cst = con.prepareCall("call loginPlan_k(?,?,?)");
//Login login = null ;
//String type=lassType.getType();
/*if(type.equals("login"))
{
login = (Login)o;
}*/
System.out.println(login.getUserName()+"DataAccess");
cst.setString(1, login.getUserName());
cst.setString(2, login.getPassword());
cst.registerOutParameter(3,java.sql.Types.INTEGER);
ResultSet rs = cst.executeQuery(query);
if(rs.next())
{ i = cst.getInt(1);}
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return i ;
}
}
これは私が受け取るエラーです
