从Java调用MongoImport

Question

我已经编写了一个.bat文件（因为我现在正在Windows上测试）:-

echo Program Starts mongoimport.exe--主机127.0.0.1-d myDB-c things--type csv--file
d:\mock_data.csv--fields id,name.f_name,name.l_name,email,gender echo Program Ends

>

我将.bat文件保存在MongoDB的/bin文件夹中。

如果我直接从Windows命令提示符调用.bat文件，该文件可以正常工作。

以下是Java控制台的输出:echo Program Starts Program Starts mongoimport.exe--host 127.0.0.1-d myDB-c things--type csv--file d:\mock_data.csv--fields id,name.f_name,name.l_name,email,gender echo Program Ends Program Ends

Answer 1

I found the solution to the problem. Following lines helped in identifying the error:-
pb.redirectErrorStream(true);
pb.redirectOutput(new File("D:\\output.txt"));

The issue was that I didn't set the 'directory' where .bat file commands will run.
pb.directory(new File("\\MongoDB\\Server\\3.2\\bin"));
