我需要将控制台输出导出到 Java 中的 2 个不同文件.在第一个文件中，我能够获取数据，而第二个文件为空 [英] I need to export console output to 2 different files in Java. In first file I'm able to get data and the second file is empty

问题描述

我需要 10 个人的详细信息，每个人的内部有不同数量的详细信息.我需要所有这些，但数据是 13 行.所以我需要所有这 13 行并像段落一样打印数据.我需要将这些数据导出到文件中，以便我可以将它们用于不同的目的.

I need details of 10 persons and inside every person there are different number of details. I need all that that but the data is in 13 rows. so i need to all these 13 rows and print data like a paragraph. I need to export this data to files so i can use them for different purposes.

 driver.findElement(By.id("searchActivitySubmitButton")).click();

    Map<String, String> map = new LinkedHashMap<>();
    PrintStream prevConsole = System.out;
    PrintStream myconsole = new PrintStream(new File("C:\FileName15.txt"));  // exporting data in first file
    
    System.setOut(myconsole);
    for (int i = 1; i <= 10; i++) {

        driver.findElement(By.xpath("(//a[contains(@id,'requestAchFileUploadDetails')])[" + i + "]")).click();  // checks the data of the first 10 people whom data i need
        
        driver.findElement(By.xpath("//a[text()='See transactions']")).click();
        Thread.sleep(3700);

        List<WebElement> listRows = driver.findElements(
                By.xpath("//table[@id='transactionActivityTable']//tr[contains(@id,'transaction_')]")); // for every row there are multiple columns which all data need to extracted. 

        for (int j = 1; j <= listRows.size(); j++) {

            driver.findElement(By.xpath(
                    "(//tr[contains(@id,'transaction_')]//i[contains(@id,'icon-activitySeeDetails')])[" + j + "]"))
                    .click();

            
            for (int k = 1; k <= 13; k++) {

                String keys = driver.findElement(By.xpath("(//dt[contains(@id,'transactionDetailDataSet')]/span/span)[" + k + "]")).getText(); // inside every person there are 13 rows. 

                String value = driver
                        .findElement(By.xpath("//dl[@class='dataset row stack center']//dd[" + k + "]")).getText();
                map.put(keys + " ; ", value);
                Thread.sleep(1000);
            }

            for (Map.Entry<String, String> m : map.entrySet()) {

                System.out.println(m.getKey() + "  " + m.getValue());

            }
            
            System.out.println("
");
        }

        Thread.sleep(1000);
        driver.navigate().back();
        Thread.sleep(3000);
        driver.navigate().back();
        Thread.sleep(5000);
        
    }
    System.setOut(prevConsole);
    myconsole.close();
    PrintStream mycons = new PrintStream(new File("C:\chase\sftp\ach_transactions_summary\Duplicate.txt")); // trying exporting data in second file
    System.setOut(mycons);
    

//数据仅在第一个文件中导出，第二个文件为空.

// Data is exporting only in first file and second file is empty.

推荐答案

Nothing output to the second file 因为您在定义 System.setOut 后没有向 System.out 发送任何内容通过 System.setOut(mycons);

Nothing outputted to the second file since you send nothing to System.out after defining System.setOut to the second file by System.setOut(mycons);
