java获取文件的inode标识符，如果文件被删除或者重命名，inode的值会发生变更，因此可以在第一次加载File之后记录inode，后续校验inode的值来判断文件是否被删除、重命名或重新创建等。
方法1
import java.io.File;
import java.nio.file.Files;
import java.nio.file.attribute.BasicFileAttributeView;
import java.nio.file.attribute.BasicFileAttributes;
/**

public class FileInodeReaderTest {
public static void main(String[] args) {
File file = new File("/logs/csp/sentinel-block.log");
try {
BasicFileAttributeView basicview = Files.getFileAttributeView(file.toPath(), BasicFileAttributeView.class);
BasicFileAttributes attr = basicview.readAttributes();
System.out.println("attr.fileKey():" + attr.fileKey()
+ " attr.creationTime:" + attr.creationTime()
+ " attr.lastModifiedTime:" + attr.lastModifiedTime());
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
}
方法2
import java.io.File;
import java.nio.file.Files;
/**
* Created by bruce on 2022/3/27 21:39
*/
public class FileInodeReaderTest {
public static void main(String[] args) {
File file = new File("/logs/csp/sentinel-block.log");
try {
Object inode = Files.getAttribute(file.toPath(), "unix:ino");
System.out.println("inode->" + inode);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
}
补充：Java INode类代码示例
INode类属于org.jbpt.petri包，在下文中一共展示了INode类的1个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Java代码示例。
示例1: getRefinedBondType
import org.jbpt.petri.INode; //导入依赖的package包/类
@Override
public WFTreeBondType getRefinedBondType(IRPSTNode<F,N> node) {
if (node.getType()!=TCType.BOND)
return WFTreeBondType.UNDEFINED;
else {
WFTreeBondType type = this.bond2type.get(node);
if (type!=null) return type;
else {
INode entry = node.getEntry();
INode exit = node.getExit();
if (entry==null || exit == null)
return WFTreeBondType.UNDEFINED;
for (IRPSTNode<F,N> child : this.getChildren(node)) {
if (child.getEntry().equals(node.getExit())) {
type = WFTreeBondType.LOOP;
this.bond2type.put(node,type);
return type;
}
}
if (entry instanceof ITransition && exit instanceof ITransition) {
type = WFTreeBondType.TRANSITION_BORDERED;
this.bond2type.put(node,type);
return type;
if (entry instanceof IPlace && exit instanceof IPlace) {
type = WFTreeBondType.PLACE_BORDERED;
return WFTreeBondType.UNDEFINED;
}
}
}
