Java - 递归所有日志文件

> 需求，递归输出某个目录下的所有日志文件，我们可以使用`commons-io`进行处理，避免重复造轮子。

## 使用

依赖

```

compile group: 'commons-io', name: 'commons-io', version: '2.6'

```

测试

```

@Test

public void testFilters(){

String outFilePath = "./logdir2";

String fileFilters[] = {".log"};

IOFileFilter[] ioFileFilters = new IOFileFilter[fileFilters.length];

for (int i = 0; i < fileFilters.length; i++) {

ioFileFilters[i] = FileFilterUtils.suffixFileFilter(fileFilters[i]);

}

File file = new File(outFilePath);

if (file.isDirectory()) {

IOFileFilter foldFilter = FileFilterUtils.and(

FileFilterUtils.directoryFileFilter(),

HiddenFileFilter.VISIBLE);

IOFileFilter fileFilter = FileFilterUtils.and(ioFileFilters);

Collection logFiles = FileUtils.listFiles(file, fileFilter, foldFilter);

for (File file1 : logFiles) {

System.out.println(file1.getName());

}

}

}

```
