Question

编辑：我有10,000个相同的文件，其中包含以下文字。

TRANSACTION_ID=9093626660000000001,VAULT_REPORT_NAME=VUpldr_QA_1Mb_Report00001,DIMENSION=REGION:Europe;LOB:All LOB;CATEGORY:RO Reporting;CUSTOMER:All Customer;FREQUENCY:Daily;REPORT AUDIENCE:Apple RO Reporting;REPORT SUBSCRIPTION:Apple RO Reporting

我的要求是在10 k文件中替换如下。

从9093626660000000001到9093626660000010000的TRANSACTION_ID。和
来自VUpldr_QA_1Mb_Report00001的VAULT_REPORT_NAME VUpldr_QA_1Mb_Report10000

所以我的输出文件内容是

档案第一名：

TRANSACTION_ID=9093626660000000001,VAULT_REPORT_NAME=VUpldr_QA_1Mb_Report00001,DIMENSION=REGION:Europe;LOB:All LOB;CATEGORY:RO Reporting;CUSTOMER:All Customer;FREQUENCY:Daily;REPORT AUDIENCE:Apple RO Reporting;REPORT SUBSCRIPTION:Apple RO Reporting

file 2nd：

TRANSACTION_ID=9093626660000000002,VAULT_REPORT_NAME=VUpldr_QA_1Mb_Report00002,DIMENSION=REGION:Europe;LOB:All LOB;CATEGORY:RO Reporting;CUSTOMER:All Customer;FREQUENCY:Daily;REPORT AUDIENCE:Apple RO Reporting;REPORT SUBSCRIPTION:Apple RO Reporting

文件10000th：

TRANSACTION_ID=9093626660000010000,VAULT_REPORT_NAME=VUpldr_QA_1Mb_Report10000,DIMENSION=REGION:Europe;LOB:All LOB;CATEGORY:RO Reporting;CUSTOMER:All Customer;FREQUENCY:Daily;REPORT AUDIENCE:Apple RO Reporting;REPORT SUBSCRIPTION:Apple RO Reporting

我写了下面的代码，但那不起作用：

import java.io.*;
import java.nio.charset.Charset;
import java.nio.charset.StandardCharsets;
import java.nio.file.FileSystems;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class mdScript {




    public static void main(String[] args) throws IOException {

        for (int i=1;i<=10000;i++){

        StringBuffer pathVarBuf = new StringBuffer();
        pathVarBuf.append("/Users/564169/Desktop/Vault_Testing/vUpldr/MD/1MbReport");
        pathVarBuf.append(i);
        pathVarBuf.append(".md");
        //System.out.println(pathVarBuf);
        Path path = Paths.get(pathVarBuf.toString());
        Charset charset = StandardCharsets.UTF_8;

        String content = new String(Files.readAllBytes(path), charset);
        content = content.replaceAll("VUpldr_QA_1Mb_Report00001", "RVUpldr_QA_1Mb_Report"+i);
        int id=999900001; // (Transaction id in the org MD file is 90)
        id = id+i;
        content = content.replaceAll("999900001", Integer.toString(id));
        Files.write(path, content.getBytes(charset));
        System.out.println(content);

        }

}

}

我收到以下错误：

Exception in thread "main" java.lang.NullPointerException
    at sun.nio.fs.UnixFileSystem.getPath(UnixFileSystem.java:267)
    at java.nio.file.Paths.get(Paths.java:84)
    at mdScript.main(mdScript.java:22)

有很多方法可以做到这一点。你也可以通过编程方式完成它。

简单的解决方案将使用TextPad 这是相同的链接 TextPad find and replace in files

在10000个文件中搜索并重复一个字符串
