1.java.util.Date转java.sql.Date时分秒丢失！！

解决：

　　使用Timestamp代替java.sql.Date:

    long curMillis = System.currentTimeMillis();
            Timestamp currentDate = new Timestamp(curMillis);
            Date time = DateUtils.parseDate(errorCodeCountBean.getTime(), NginxConfig.TIME_PATTERN);

            String sql = "insert into ERROR_CODE_COUNT (ID, ERRCODECOUNT,TIME,CREATE_DATE,UPDATE_DATE) VALUES (?,?,?,?,?)";
            pstmt = conn.prepareStatement(sql);
            pstmt.setLong(1, curMillis);
            pstmt.setInt(2, errorCodeCountBean.getErrcodecount());
            pstmt.setTimestamp(3, new Timestamp(time.getTime()));
            pstmt.setTimestamp(4, currentDate);
            pstmt.setTimestamp(5, currentDate);

2.Strom一个Bolt对象只能用一次：

下面的printBolt对象使用了两次：

PrinterBolt printBolt=new PrinterBolt();
builder.setBolt("print", printBolt,1).shuffleGrouping("ErrorCodeStatisticsBolt");
builder.setBolt("print", printBolt,1).shuffleGrouping("UVRealTimeBolt");
