从理论上讲,应该可以从 Java 程序本身运行 javadoc 生成过程(如此处所述http://docs.oracle.com/javase/7/docs/technotes/guides/javadoc/standard-doclet.html#runningprogrammatically) . 我从这里获取程序并稍微更改它,如下所示。但是,当我从类的 mainmethod 调用 doTest 方法时,我总是从导致错误的执行函数中获取返回代码“1”。

static void doTest() {
    ByteArrayOutputStream redirectedOutput = new ByteArrayOutputStream();
    PrintStream originalOutput = System.out;

    // redirect System.out to a buffer
    System.setOut(new PrintStream(redirectedOutput));

    PrintWriter sink = new PrintWriter(new ByteArrayOutputStream());

    // execute javadoc
    int result = com.sun.tools.javadoc.Main
            .execute(
                    "javadoc", sink, sink, sink,
                    "com.sun.tools.doclets.standard.Standard",
                    new String[] {
                            "-sourcepath",
                            "\"C:\\Program Files (x86)\\Java\\jdk1.7.0_51\\src\\\"",
                            "java.util" });

    // test whether javadoc did any output to System.out
    if (redirectedOutput.toByteArray().length > 0) {
        originalOutput
                .println("Test failed; here's what javadoc wrote on its standard output:");
        originalOutput.println(redirectedOutput.toString());
        throw new Error("javadoc output wasn\'t properly redirected");
    } else if (result != 0) {
        throw new Error("javadoc run failed " + result);
    } else {
        originalOutput.println("OK, good");
    }
}

我可以使用以下行生成 javadoc:

C:\Program Files (x86)\Java\jdk1.7.0_51\bin>javadoc -sourcepath ..\src\ -d "C:\Users\leo\Eigene Dateien\javadoc" java.util

我的环境是带有 JDK 1.7.0_51 的 Windows。

我正在以不同的方式执行它,请参阅我的问题 - Doclet: firstSentence is null

我会说(没有测试),你的参数应该是这样的:

    String[] params = new String[] {
            "-doclet", "com.sun.tools.doclets.standard.Standard",
            "-sourcepath", "C:\\Program Files (x86)\\Java\\jdk1.7.0_51\\src\\",
            "java.util"
    };
    com.sun.tools.javadoc.Main.execute(params);
