输出类和方法注释等信息

前提：需导入tools.jar

package com.xx;

import com.sun.javadoc.ClassDoc;
import com.sun.javadoc.MethodDoc;
import com.sun.javadoc.RootDoc;

public class JavaDocUse {
    private static RootDoc rootDoc;
    public static  class Doclet {
        public static boolean start(RootDoc rootDoc) {
            JavaDocUse.rootDoc = rootDoc;
            return true;
        }
    }

    /**
     * 显示DocRoot中的基本信息
     */
    public static void show(){
        ClassDoc[] classes = rootDoc.classes();
        for(ClassDoc classDoc : classes){
            System.out.println(classDoc.name()+'
'+
                    "类的注释:"+classDoc.commentText());
            MethodDoc[] methodDocs = classDoc.methods();
            System.out.println("==========================方法分割线===========================");
            for(MethodDoc methodDoc : methodDocs){
                // 打印出方法上的注释
                System.out.println(""
                        +classDoc.name()+","
                        +methodDoc.name()+
                        "方法注释:"
                        +methodDoc.commentText());
            }
        }
    }

    public static void main(String[] args) {
        com.sun.tools.javadoc.Main.execute(new String[] {"-doclet",
                Doclet.class.getName(),
                "-encoding","utf-8","-classpath",
                "*",
                "D:\workplace\src\main\java\com\gcc\jvmc\api\client\supplier\service\xx.java"});
        show();
    }
