如何在运行时获取方法的 JavaDoc? [英] How to get a JavaDoc of a method at run time?

问题描述

在运行时获取Class的方法名很容易
但是
如何在运行时获取方法的 JavaDoc ?

Its easy to get a method Name of a Class at run time
BUT
How i can get a JavaDoc of a method at run time ?

如下例

包含目标方法的JavaDoc的类

public class MyClass {
    /**
     * 
     * @param x value of ....
     * @return result of ....
     */
    public String myMethod(int x) {
        return "any value";
    }

}

我们的类有一个 main 方法

Our Class that has a main method

public class TestJava {
    public static void main(String[] args) {
        // get Class method Name at run time
        String methodName = MyClass.class.getMethods()[0].getName();
        System.out.println(methodName); // will print myMethod
        // How to  get a JavaDoc of myMethod `method` at run time
        // MyClass.class.getMethods()[0].????
        // expected to print a JavaDoc of myMethod
    }
}

推荐答案

你不能:class 文件不包含注释.

You can't : the class file doesn't contain the comments.

解决方案"是在构建程序时将 javadoc 生成为 HTML，并根据类名和方法名构建 URL.您还可以使用 doclet API.

A "solution" would be to generate the javadoc as HTML when you build your program and to build an URL from the name of the class and the name of the method. You could also generate the javadoc in a more suitable format than HTML using the doclet API.
