我正在尝试将一条记录插入我正在使用 Spring 3.0 的数据库中。我没有使用 Hibernate 或任何持久性框架。想知道 DAO 是否正确编写或有什么不同的编写方式：

public void saveOfficer(Officers officer) {
        logger.info("In saveOfficer");
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

        try{

            logger.info("Values are "+officer.getUserName()+" "+officer.getPassword()+" "+officer.getfName()+" "+officer.getoName()+" "+officer.getDivisionNo()+" "+officer.getPositionId()+" "+officer.getEmailAdd()+" "+dateFormat.format(officer.getStartDate())+" "+dateFormat.format(officer.getEndDate())+" "+ officer.getGenderId()+" "+officer.getPhoneNo()+" "+dateFormat.format(officer.getDob()));


            String sql= "INSERT INTO crimetrack.tblofficers (userName,password, fName, lName, oName, " +
                        "divisionNo, poisitionId, emailAdd, startDate, endDate, genderId, " +
                        "phoneNo, dob) VALUES (:userName,:password, :fName, :lName, :oName, :divisionNo, "+
                        ":poisitionId, :emailAdd, :startDate, :endDate, :genderId, " +
                        ":phoneNo, :dob)";



            logger.debug("Executing saveOfficer String " + sql);
            int count = getJdbcTemplate().update(sql,new MapSqlParameterSource()
                    .addValue("userName",officer.getUserName())
                    .addValue("password", officer.getPassword())
                    .addValue("fName", officer.getfName())
                    .addValue("lName", officer.getlName())
                    .addValue("oName", officer.getoName())
                    .addValue("divisionNo", officer.getDivisionNo())
                    .addValue("positionId",officer.getPositionId())

                    .addValue("phoneNo",officer.getPhoneNo())
                    .addValue("dob", dateFormat.format(officer.getDob())));

            System.out.println(sql);
            logger.info(count +" Rows affected in tblOfficers");



        }catch(Exception e){

            logger.error("Could not save officer ", e);
        }


    }

我重新编写了代码，这对我有用：

public void saveOfficer(Officers officer) {
        logger.info("In saveOfficer");
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");


        try{

            logger.info("Values are "+officer.getUserName()+" "+StringSecurity.EncryptString(officer.getPassword())+" "+officer.getfName()+" "+officer.getoName()+" "+officer.getDivisionNo()+" "+officer.getPositionId()+" "+officer.getEmailAdd()+" "+dateFormat.format(officer.getStartDate())+" "+dateFormat.format(officer.getEndDate())+" "+ officer.getGenderId()+" "+officer.getPhoneNo()+" "+dateFormat.format(officer.getDob()));

            int count = getJdbcTemplate().update("INSERT INTO crimetrack.tblofficers (userName,password, fName, lName, oName, divisionNo, positionId, emailAdd, startDate, endDate, genderId,phoneNo, dob,badgeNo) "+
                                                "VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?)"
                                                , new Object[]{officer.getUserName(),StringSecurity.EncryptString(officer.getPassword()),officer.getfName(),
                                                 officer.getlName(),officer.getoName(),officer.getDivisionNo(),officer.getPositionId(),
                                                 officer.getEmailAdd(),officer.getStartDate(),officer.getEndDate(),officer.getGenderId(),
                                                 officer.getPhoneNo(),officer.getDob(),officer.getBadgeNo()});

        logger.info(count +" Rows affected in tblOfficers");



        }catch(Exception e){

            logger.error("Could not save officer ", e);
        }       
    }
