我有一个具有不同值的 CMR 文件，但我不知道如何使用分隔符。我想使用带有按钮的 java netbeans 将“numberPacketsLost”、“jitter”和“latency”存储到 mySQL 数据库中。

谢谢！:)

来自 cmr 文件的代码：

"cdrRecordType","globalCallID_callManagerId","globalCallID_callId","nodeId","directoryNum","callIdentifier","dateTimeStamp","numberPacketsSent","numberOctetsSent","numberPacketsReceived","numberOctetsReceived","numberPacketsLost","jitter","latency","pkid","directoryNumPartition","globalCallId_ClusterID","deviceName","varVQMetrics"
INTEGER,INTEGER,INTEGER,INTEGER,VARCHAR(50),INTEGER,INTEGER,INTEGER,INTEGER,INTEGER,INTEGER,INTEGER,INTEGER,INTEGER,UNIQUEIDENTIFIER,VARCHAR(50),VARCHAR(50),VARCHAR(129),VARCHAR(600)

您需要打开 cmr 文件，逐行阅读，跳过标题并提取数据。获得所需数据后，只需编写查询以插入数据库。

BufferedReader br = new BufferedReader(new FileReader(new File("myCmrFile")));
String line = null;
int linecount = 0;
while ((line = br.readLine()) != null){
    if (linecount++ < 2) // skip the headers
        continue;
    // split the data and convert to integers
    String[] data = line.split(",");
    Integer packetsLost = Integer.valueOf(data[10]); 
    Integer jitter = Integer.valueOf(data[11]); 
    Integer latency = Integer.valueOf(data[12]); 
    // now insert into the db, query will look something like this
    String query = "INSERT INTO myTable (numberPacketsLost, jitter, latency) VALUES(?,?,?)";
    PreparedStatement ps = connection.prepareStatment(query);
    ps.setInt(1, packetsLost);
    ps.setInt(2, jitter);
    ps.setInt(3, latency);
    ps.executeUpdate();
}

此代码无法完全正常工作，您需要根据数据库的实际值对其进行更改。
