我想自定义Checkstyle JavadocVariable规则,以便它不会抱怨具有@FindBy
注释的字段。
class Demo{
@FindBy(id = "new-button")
public WebElement createButton; //<- no JavaDoc required because it is a field "injected" by selenium
public String otherField; //<- complain about missing Java doc
}
但我不清楚如何在checkstyle.xml
文件中指定它。有人有想法吗?
在此用例中不起作用的事情:
SuppressWithNearbyCommentFilter
不起作用,因为它是注释但不是注释 答案 0 :(得分:10)
我知道几种解决方案,但所有这些解决方案都需要做额外的工作。
JavadocVariableCheck
,可以在提供注释的情况下跳过检查。SuppressWarningsHolder
+ SuppressWarningsFilter
,但带有注释支持)@FindBy
并忽略后面的两行。我的解决方案(最简单的一个):
package org.aap.checks;
import com.google.common.collect.Lists;
import com.puppycrawl.tools.checkstyle.api.AuditEvent;
import com.puppycrawl.tools.checkstyle.api.AutomaticBean;
import com.puppycrawl.tools.checkstyle.api.FileContents;
import com.puppycrawl.tools.checkstyle.api.Filter;
import com.puppycrawl.tools.checkstyle.checks.FileContentsHolder;
import java.lang.ref.WeakReference;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
public class SuppressWithAnnotationFilter
extends AutomaticBean
implements Filter {
public class Tag implements Comparable<Tag> {
private final int firstLine;
private final int lastLine;
public Tag(int firstLine, int lastLine) {
this.firstLine = firstLine;
this.lastLine = lastLine;
}
@Override
public int compareTo(Tag other) {
if (firstLine == other.firstLine) {
return lastLine - other.lastLine;
}
return (firstLine - other.firstLine);
}
public boolean isMatch(AuditEvent event) {
final int line = event.getLine();
return line >= firstLine && line <= lastLine;
}
@Override
public final String toString() {
return "Tag[lines=" + firstLine + " to " + lastLine + "]";
}
}
private final List<Tag> tags = Lists.newArrayList();
private WeakReference<FileContents> fileContentsReference =
new WeakReference<FileContents>(null);
public FileContents getFileContents() {
return fileContentsReference.get();
}
public void setFileContents(FileContents fileContents) {
fileContentsReference = new WeakReference<FileContents>(fileContents);
}
@Override
public boolean accept(AuditEvent event) {
if (event.getLocalizedMessage() == null) {
return true; // A special event.
}
final FileContents currentContents = FileContentsHolder.getContents();
if (currentContents == null) {
return true;
}
if (getFileContents() != currentContents) {
setFileContents(currentContents);
tagSuppressions();
}
for (final Iterator<Tag> iter = tags.iterator(); iter.hasNext(); ) {
final Tag tag = iter.next();
if (tag.isMatch(event)) {
return false;
}
}
return true;
}
private void tagSuppressions() {
tags.clear();
final FileContents contents = getFileContents();
String[] contentsLines = contents.getLines();
for (int i = 0; i < contentsLines.length; i++) {
if (contentsLines[i].contains("@FindBy")) {
tags.add(new Tag(i+1, i+2));
}
}
Collections.sort(tags);
}
}
将结果类添加到checkstyle任务的类路径中,然后在checkstyle.xml
中指定过滤器:
<?xml version="1.0"?>
