Java 读取行与行之间的数据

我有一个每15分钟收集一次NMON数据的进程。我对将内容读入列表或仅使用Java8流有基本的了解

我在迭代

ZZZZ，t001.xxxx和
ZZZZ，T000X，xxx之间的数据时遇到困难

读取2019年11月15日至T0001,00:15:39,15至T0002,00:30:39,15至2019年11月15日之间的数据
将
CPU\u ALL，T0001,7.3,1.6,0.3,90.9,8.8,48
添加到CPUData（实体）
新CPUData（'2019年11月15日'，'00:15:39'，7.3,1.6,0.3,90.9,8.8,48）

其他数据实体
重复，直到找到最后一个ZZZZ条目

如有任何建议，将不胜感激

我当前的测试用例

public static void main(String[] args) {
        String dirName = "c:\\sampleFiles";
        String fileName = "c:\\sampleFiles\\test.nmon";
        List<String> list = new ArrayList<>();
        try {
            Files.list(new File(dirName).toPath())
            .forEach(path-> {
                System.out.println(path);
                 BufferedReader reader;
                FileReader fileReader;
                try {
                    fileReader = new FileReader(path.toString());
                    reader = new BufferedReader(fileReader);
                    String line = reader.readLine();
                    while (line != null) {
                        System.out.println(line);
                        line = reader.readLine();
                    }
                    reader.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }

以下是NMON文件中的示例数据

这不是一个解决方案，只是一个关于如何按ID（T000x）分组的想法，然后您可以迭代这些组，并根据类型（ZZZZ，CPU…）应用您想要的任何内容

您将得到一个映射，其中键是T000x，值是属于某个T000x的行的列表

try {
        // Read all lines to a List
        List<String> lines = Files.readAllLines(Paths.get(fileName));

        Map<String, List<String>> group = new HashMap<>();

        // Get only IDs -  T0001, T0002 ...
        List<String> t000s = lines.stream()
                .filter(line -> line.startsWith("ZZZZ"))
                .map(line -> line.split(",")[1]) 
                .collect(Collectors.toList());

        // Filter lines by ID
        t000s.forEach(t -> {
            List<String> filtered = lines.stream()
                    .filter(line -> line.contains(t)) 
                    .filter(line -> line.startsWith("CPU") || line.startsWith("ZZZZ"))
                    .collect(Collectors.toList());
            group.put(t, filtered);
        });

    } catch (IOException e) {
        e.printStackTrace();
    }

试试看{
//读取列表中的所有行
列表行=Files.readAllLines（path.get（fileName））；
映射组=新的HashMap（）；
//只获取ID-T0001、T0002。。。
列表t000s=lines.stream（）
.filter（line->line.startsWith（“ZZZZ”））
.map（直线->直线分割（“，”[1]）
.collect（Collectors.toList（））；
//按ID筛选行
t000s.forEach（t->{
List filtered=lines.stream（）
.filter（行->行.contains（t））
.filter（line->line.startsWith（“CPU”）| | line.startsWith（“ZZZZ”））
.collect（Collectors.toList（））；
组。put（t，过滤）；
});
}捕获（IOE异常）{
e、 printStackTrace（）；
}
我建议查看已有的NMON解析器。我提供以下链接


以上代码是NMON visualizer的一部分。我在这里提供链接

如果我理解正确，您所需要的只是以
“CPU\u all”
开头的行。如果您可以向CPUData类添加一个新的构造函数，那么它就相对简单

首先添加一个接受字符串的构造函数：

public CPUData (String line){
    String[] data = line.split(",");
    this.date = LocalDate.parse(data[0]);
    this.time = LocalTime.parse(data[1]);
    this.value1 = Double.parseDouble(data[2]);
    this.value2 = Double.parseDouble(data[3]);
    ....
}

然后，只需像上面所做的那样对行进行流式处理，过滤以
“CPU\u ALL”
开头的行，并将它们映射到一个CPUData对象

List<CPUData> list = new ArrayList<>();

try (Stream<CPUData> stream = Files.lines(Paths.get(fileName))){
        list = stream.filter(line -> line.startsWith("CPU_ALL"))
                     .map(line -> new CPUData(line))
                     .collect(Collectors.toList());
} catch (IOException e) {
        e.printStackTrace();
}
//do whatever with the list of CPUData´s
list.forEach(System.out::println);

List List=new ArrayList（）；
try（Stream=Files.line（path.get（fileName）））{
list=stream.filter（line->line.startsWith（“CPU\u ALL”））
.map（行->新CPUData（行））
.collect（Collectors.toList（））；
}捕获（IOE异常）{
e、 printStackTrace（）；
}
//对CPUData的列表执行任何操作
list.forEach（System.out:：println）；

public CPUData (String line){
    String[] data = line.split(",");
    this.date = LocalDate.parse(data[0]);
    this.time = LocalTime.parse(data[1]);
    this.value1 = Double.parseDouble(data[2]);
    this.value2 = Double.parseDouble(data[3]);
    ....
}

List<CPUData> list = new ArrayList<>();

try (Stream<CPUData> stream = Files.lines(Paths.get(fileName))){
        list = stream.filter(line -> line.startsWith("CPU_ALL"))
                     .map(line -> new CPUData(line))
                     .collect(Collectors.toList());
} catch (IOException e) {
        e.printStackTrace();
}
//do whatever with the list of CPUData´s
list.forEach(System.out::println);
