java - Spring MVC 使用 GeneratedKeyHolder() - java.io.NotSerializableException

Question

我正在尝试使用 jdbcTemplate 和 GeneratedKeyHolder() 预先插入到 mysql 数据库中，以检索自动生成的 PK colum 值。但是我遇到了一个异常(exception)。如果我删除 keyHolder 参数，记录将完美插入，但是我无法获得自动生成的 PK 正弦 keyHolder 已被删除。 Crime 类实现了 Serializable。下面是代码:

如何构造语句以便接收 keyHolder 值？

DAO

KeyHolder keyHolder = new GeneratedKeyHolder();
logger.debug("In saveCrime");
logger.debug("In saveCrime");
sql = "INSERT INTO crimeTrack.tblcrimes (crimeDetails, " +
    "crimeLatLocation,crimeLongLocation, crimeStreetLn1, crimeStreetLn2, crimeDate, "+
    "recordedById,statusId, offenceCatId, offenceTypeId, crimeLevelId, investigatingOfficerId,crimeTime) " +
    "VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?)";

int save = getJdbcTemplate().update(new PreparedStatementCreator(){

    public java.sql.PreparedStatement createPreparedStatement(
        java.sql.Connection connection) throws SQLException {
            PreparedStatement ps =(PreparedStatement) connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
            ps.setString(1, crime.getCrimeDetails());
            ps.setFloat(2, (float)crime.getCrimeLatLocation());
            ps.setFloat(3, (float)crime.getCrimeLongLocation());
            ps.setString(4, crime.getCrimeStreetLn1());
            ps.setString(5, crime.getCrimeStreetLn2());
            ps.setString(6,  crime.getCrimeDate());
            ps.setString(7, "sim");
            ps.setInt(8, crime.getStatusId());
            ps.setInt(9, crime.getOffenceCatId());
            ps.setInt(10, crime.getOffenceTypeId());
            ps.setInt(11, crime.getCrimeLevelId());
            ps.setString(12, crime.getInvestigatingOfficerId());
            ps.setString(13, crime.getCrimeTime()); 

            return ps;
        }
    },keyHolder);

哥们，我看看有什么问题。虽然你提到了那个例子的引用，但我相信你使用了错误的jdbctemplate方法。检查 api .您对该示例使用了不同的方法。
