Install and use AMATERASUML, Modelspoon to generate Java class diagrams under Eclipse __java

1. Installation and use of AMATERASUML
Before installing AMATERASUML, you need to install GEF
Install it using Eclipse Online installation.
Eclipse Online Installation GEF address: http://download.eclipse.org/tools/gef/updates/releases/
After installing GEF, install AMATERASUML
Download first to the following address: http://sourceforge.jp/projects/amateras/downloads/56447/AmaterasUML_1.3.4.zip/
After decompression, put the files inside the Eclipse's plugins folder and restart Eclipse. Choose "File"-> "New"-> "other" and you can see the AMATERASUML option.

This tool, the feeling from class diagram automatically generated Java class is easier, easy to use. However, I found a half-day including online search, how to automatically convert from Java classes to Java class diagram, has not been made. So I found a more powerful Eclipse plug-in--modelspoon that automatically generates Java class diagrams online. The brother is very strong, just drag the. java file directly into it, it can directly generate Java class diagram. Very easy to use.

2. Installation and use of Modelspoon
Function: can generate class diagrams of existing Java classes in eclipse
One: what is Modelgoon.
It is an Eclipse plug-in for model design based on UML diagrams and reverse engineering (that is, generating class diagrams from existing source code).
Two: Installation
Download Modelgoon-4.4.1-site.zip to your computer and choose Help-->install new software from Eclipse. In Work with--> Add Select the Modelgoon-4.4.1-site.zip that have already been downloaded and complete the installation all the way next.
Three: Use
After the installation is successful, in Eclipse File-->new-->other-->modelgoon diagrams Select Class Diagram, in its own Java project, create a suffix is. mgc file, use it to generate class diagrams. The usage is very simple, drag Java class directly to this file view, will automatically generate UML class diagram.
