Support for generating Javadoc documentation

[shalousun]

Description

Community users hope that smart-doc can generate simple Javadoc, such as documentation for some interface classes and static utility classes.
社区用户希望smart-doc能成生成简单的javadoc，例如针对一些接口类，静态工具类生成文档。 #683

Implementation

• Define a custom @javadoc annotation tag. Classes annotated with @javadoc will have a Javadoc document generated by smart-doc.
  定义一个自定义的@javadoc注释tag，标注了@javadoc的类，smart-doc会生成一个javadoc文档
• The generation of Javadoc is basically similar to the current Dubbo documentation. The Javadoc documentation needs to remove Protocol and URI attributes.
  实现javadoc的生成基本和当前dubbo的文档类似，javadoc文档需要去除Protocol、URI属性
• Add a javadoc mojo in the Maven plugin.
  在maven插件中增加一个javadoc的mojo

I am very interested in this topic. Is there anything I can participate in to speed up the implementation of this function?

[shalousun]

Yes, we would very much welcome your participation and contributions.

Okay, let me take a look at your implementation idea and do some code research.

@shalousun Hello, I would like to ask when our version 3.0.5 will be released?

@shalousun Hello, I would like to ask when our version 3.0.5 will be released?

I tested it today, and the current Javadoc needs to be optimized. The definition of methods in the Javadoc needs to know the modifiers, such as the difference between static methods and ordinary public instance methods.

After this optimization is completed, we can schedule a release for version 3.0.5 next week.
