我发现绿色插件非常简单，使用和生成类图从源代码。 试一试吧。 只需将插件复制到插件目录。

你的代码库是什么?Java还是c++ ?

eUML2 for Java is a powerful UML modeler designed for Java developper in Eclipse. The free edition can be used for commercial use. It supports the following features: CVS and Team Support Designed for large project with multiple and customizable model views Helios Compliant Real-time code/model synchronization UML2.1 compliant and support of OMG XMI JDK 1.4 and 1.5 support The commercial edition provides: Advanced reversed engineering Powerful true dependency analyze tools UML Profile and MDD Database tools Customizable template support

ObjectAid UML Explorer

是我用的。它很容易从存储库安装:

Name:     ObjectAid UML Explorer
Location: http://www.objectaid.com/update/current

并生成相当不错的UML图:

网站描述:

The ObjectAid UML Explorer is different from other UML tools. It uses the UML notation to show a graphical representation of existing code that is as accurate and up-to-date as your text editor, while being very easy to use. Several unique features make this possible: Your source code and libraries are the model that is displayed, they are not reverse engineered into a different format. If you update your code in Eclipse, your diagram is updated as well; there is no need to reverse engineer source code. Refactoring updates your diagram as well as your source code. When you rename a field or move a class, your diagram simply reflects the changes without going out of sync. All diagrams in your Eclipse workspace are updated with refactoring changes as appropriate. If necessary, they are checked out of your version control system. Diagrams are fully integrated into the Eclipse IDE. You can drag Java classes from any other view onto the diagram, and diagram-related information is shown in other views wherever applicable.

我推荐PlantUML。这个工具非常有用，很容易使用。PlantUML有一个Netbeans插件，你可以用你的java代码创建UML图。

在netbeans中安装PlantUML插件的方法如下:

Netbeans菜单->工具->插件

现在选择可用插件，然后找到PlantUML并安装它。

到目前为止，我用过的最好的逆向工程工具和往返java -> UML是Borland's Together。它是基于Eclipse的(不仅仅是一个插件)，而且工作得非常好。

PlantUML怎么样? 这不是逆向工程!!这是在编码之前的工程设计。
