Eclipse Generation Javadoc method and error resolution

You may need to generate Javadoc files on your own after you write a project, and now I'm going to talk about some of the issues I have in this process. 1. Generate Javadoc

First select the project you want to build, right-click, select Export, then select Javadoc under Java in the Export dialog box, and then next.
To the Javadoc generation interface, where:
Javadoc command: Select Bin/javadoc.exe for JDK
Destination: Save path for the build document
Submit to finish (finish) to start building the document. 2. Coding Problems

Direct finish after the error:

Sweat...... This also wants to set the code to say ....

View the javadoc-help under CMD

Visible set encoding method as in the figure white mark part

Go back to the previous step and fill in the following

3. Marking Problems

The error message is as follows:

This is because @date this tag does not exist in the default, we need to manually add

In the same vein, view javadoc-help under cmd

Add in the same place as the above coding problem:
-tag date:a: "Date"

Error resolution 4. Don't forget to add content to annotations

This is because we made a comment, but did not add any content, as follows:

/** *
File Upload *
@param files
* @return

1 2 3 4 5 1 2 3 4 5

The description of the attribute here is not, and needs to be modified

/** *
File Upload * @param file *        uploaded files 
* @return
*        return information
* *

1 2 3 4 5 6 7 1 2 3 4 5 6-7

Looking at these 55 said I did not describe the information, I really want to cry without tears, can only blame myself when the statement was too careless.

To give you advice, be sure to write a good specific content.
