我试图让做SQL插入时,标识列回到了我的Java程序。 运行代码时,我收到以下错误
Uncaught exception thrown in one of the service methods of the
servlet: Cocoon. Exception thrown : java.lang.AbstractMethodError: java/sql
/Connection.prepareStatement(Ljava/lang/String;I)Ljava/sql/PreparedStatement;
这里是我运行的代码。
private void insertUserInputParameters(ReportData rptData){
UserInputParameters userParams = rptData.getUserInputData();
StringBuilder sql = new StringBuilder();
PreparedStatement pstmt = null;
ResultSet rs = null;
int userDataId = -1;
//Get a database connection.
sl = ServiceLocator.getInstance();
ds = sl.getDataSource("jdbc/collegeguide");
con = ds.getConnection();
con.setReadOnly(false);
sql.append("insert into cpgusrdtaf (statecd, addr1, addr2, city, state, ");
sql.append("zipcode, dependent, shdindic, marstatus, residency, prntatge, ");
sql.append("fincome, mincome, pincome, taxspaid, taxreturn, elig1040, ");
sql.append("gincome, pcash, inetwrth, bnetwrth, pbenefit, paddlinf, ");
sql.append("puntax, pdslcwrk, smstatus, sresidncy, studtr, stud1040, ");
sql.append("sadjinc, sincome, spincome, sdslcwrk, studtax, scash, ");
sql.append("sinvest, snetwrth, saddlinf, suntax, househld, nmbrsch, ");
sql.append("studact, studsat, schools, housing) ");
sql.append("values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?, ");
sql.append("?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
//This line of code is where I get the error**
pstmt = con.prepareStatement(sql.toString(), Statement.RETURN_GENERATED_KEYS);
//If I remove the 'Statement.RETURN_GENERATED_KEYS' I do not get the error.**
pstmt = con.prepareStatement(sql.toString());
setStatementValues(pstmt, userParams);
pstmt.executeUpdate();
rs = pstmt.getGeneratedKeys();
if(rs.next()){
userDataId = rs.getInt(1);
}
我不能使用存储过程,所以我不能走这条路。 任何帮助将不胜感激
我使用Java 1.5
在此先感谢道格
