含有T的字符串转LocalDateTime

2021-10-10T10:10:10 含有T的字符串转LocalDateTime

DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE_TIME;
LocalDateTime dateTimeParked = LocalDateTime.parse(rs.getObject(columnIndex).toString(), formatter);

来源：

@Component
@MappedTypes(LocalDateTime.class)
@MappedJdbcTypes(value = JdbcType.DATE, includeNullJdbcType = true)
public class LocalDateTimeTypeHandler extends BaseTypeHandler<LocalDateTime> {

    @Override
    public void setNonNullParameter(PreparedStatement ps, int i, LocalDateTime parameter, JdbcType jdbcType)
            throws SQLException {
        ps.setObject(i, parameter);
    }

    @Override
    public LocalDateTime getNullableResult(ResultSet rs, String columnName) throws SQLException {
         return DateUtil.toLocalDateTime(rs.getObject(columnName));
    }

    @Override
    public LocalDateTime getNullableResult(ResultSet rs, int columnIndex) throws SQLException {
       // return Convert.toLocalDateTime(rs.getObject(columnIndex));
        DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE_TIME;
        LocalDateTime dateTimeParked = null;
        try {
             dateTimeParked = LocalDateTime.parse(rs.getObject(columnIndex).toString(), formatter);
        }catch (Exception ex){
            dateTimeParked = ((Timestamp)rs.getObject(columnIndex)).toLocalDateTime();
        }
        return dateTimeParked;
    }

    @Override
    public LocalDateTime getNullableResult(CallableStatement cs, int columnIndex) throws SQLException {
        //return Convert.toLocalDateTime(cs.getObject(columnIndex));

        DateTimeFormatter formatter = DateTimeFormatter.ISO_LOCAL_DATE_TIME;
        LocalDateTime dateTimeParked = null;
        try{
            dateTimeParked =LocalDateTime.parse(cs.getObject(columnIndex).toString(), formatter);
        }catch (Exception ex){
            dateTimeParked = ((Timestamp)cs.getObject(columnIndex)).toLocalDateTime();
        }
        return dateTimeParked;
    }
}

try catch 可以用以下工具类替换：

public static LocalDateTime toLocalDateTime(Object obj){
    LocalDateTime localDateTime = null;
    if(obj instanceof java.sql.Timestamp){
        localDateTime = ((Timestamp)obj).toLocalDateTime();
    }
    if(obj instanceof java.time.LocalDateTime){
        localDateTime = (LocalDateTime)obj;
    }
    return localDateTime;
}
