请参阅Javadoc Tool Home Page的 Doclets 部分了解标准方法。
Doclets 标准doclet生成HTML并内置到Javadoc工具中。这里列出了Java Software开发的其他doclet。 ..
特别参见Example - Subclassing the Standard Doclet& Doclet API。

使用:javadoc * .java生成它们,然后根据需要重写stylesheet.css ...

作为替代方案,您可以考虑我编写的一个名为FilteredLineIterator
的类,它可以用来从源文件中抓取所有JavaDoc行。
(这个答案类似于我在this question中写的那个。)
FilteredLineIterator
是一个字符串迭代器,它根据"实体"过滤(保留或抑制)另一个迭代器中的元素。 (单行,块和"隐身"块),每行存在。保留行可以选择修改。
(FilteredLineIterator
是XBN-Java的一部分.Jars可以下载here。)
示例顶部和设置:
import com.github.xbn.linefilter.FilteredLineIterator;
import com.github.xbn.linefilter.KeepUnmatched;
import com.github.xbn.linefilter.Returns;
import com.github.xbn.linefilter.entity.BlockEntity;
import com.github.xbn.linefilter.entity.EntityRequired;
import com.github.xbn.linefilter.entity.KeepMatched;
import com.github.xbn.linefilter.entity.NewBlockEntityFor;
import com.github.xbn.linefilter.entity.NewStealthBlockEntityFor;
import com.github.xbn.linefilter.entity.StealthBlockEntity;
import com.github.xbn.testdev.GetFromCommandLineAtIndex;
import com.github.xbn.util.IncludeJavaDoc;
import java.util.Iterator;
/**
<P>{@code java ExtractAllJavaDocBlockTextRaw examples\com\github\xbn\examples\linefilter\JavaClassWithOneCommentAndTwoJavaDocBlocks_input.txt}</P>
**/
public class ExtractAllJavaDocBlockTextRaw {
public static final void main(String[] cmd_lineParams) {
//Example setup:
Iterator<String> rawInputLineItr = GetFromCommandLineAtIndex.fileLineIterator(
cmd_lineParams, 0,
null); //debugPath
主要部分从下面开始。 JavaDoc块定义为block entity,其中仅保留中间(不是开始或结束)行。为了防止在阻止打开之前找到错误的&#34;结束行&#34;错误 - 因为JavaDoc和&#34;正常&#34;的结束行(非JavaDoc)多行注释为*/
- 必须声明正常多行注释的stealth block。
输入的原始行迭代器和两个实体都被送到过滤后的行迭代器。
StealthBlockEntity javaMlcBlock = NewStealthBlockEntityFor.javaComment(
"comment", IncludeJavaDoc.NO,
null, //dbgStart (on=System.out, off=null)
null, //dbgEnd
KeepMatched.NO, EntityRequired.YES, null,
null); //dbgLineNums
BlockEntity javaDocBlock = NewBlockEntityFor.javaDocComment_Cfg(
"doccomment",
null, //dbgStart
null, //dbgEnd
EntityRequired.YES, null,
null). //dbgLineNums
keepMidsOnly().build();
FilteredLineIterator filteredItr = new FilteredLineIterator(
rawInputLineItr, Returns.KEPT, KeepUnmatched.NO,
null, null, //dbgEveryLine and its line-range
javaMlcBlock, javaDocBlock);
while(filteredItr.hasNext()) {
System.out.println(filteredItr.next());
}
}
}
输出(输入文件位于此答案的底部):
<P>The main class JavaDoc block.</P>
<P>Constructor JavaDoc block</P>
* <P>Function JavaDoc block.</P>
* <P>This function does some stuff.</P>
* <P>Lots and lots of stuff.</P>
要从每一行中删除可选的星号,包括任何前面的空格,请添加一个&#34;中线变换器&#34;到JavaDoc块实体:
TextLineAlterer asteriskStripper = NewTextLineAltererFor.replacement(
Pattern.compile("[ \t]*(?:\\*[ \t]*)?(.*)"), "$1",
ReplacedInEachInput.FIRST,
null, //debug
null);
通过将keepMidsOnly().build();
更改为
midAlter(asteriskStripper).keepMidsOnly().build();
输出:
<P>The main class JavaDoc block.</P>
<P>Constructor JavaDoc block</P>
<P>Function JavaDoc block.</P>
<P>This function does some stuff.</P>
<P>Lots and lots of stuff.</P>
输入文件:
/*
A Java comment block.
*/
package fully.qualified.package.name;
/**
<P>The main class JavaDoc block.</P>
*/
public class StayClassy {
/**
<P>Constructor JavaDoc block</P>
*/
public StayClassy() {
//Do stuff
}
/**
* <P>Function JavaDoc block.</P>
* <P>This function does some stuff.</P>
* <P>Lots and lots of stuff.</P>
*/
public void doStuff() {
}
