另一个Java建模工具是我的网站GitUML。 从存储在GitHub存储库中的Java或Python代码生成UML图。

GitUML的一个关键思想是解决“文档化”的一个问题:图总是过时的。使用GitUML，当您使用git推送代码时，图表会自动更新。

浏览社区UML图，有一些Java设计模式。浏览流行的GitHub存储库，并可视化其中的架构和模式。

使用指向和单击创建图表。没有拖放编辑器，只需点击你想要可视化的存储库树中的类:

底层技术是基于PlantUML的，这意味着您可以使用额外的PlantUML标记来改进您的图表。

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.

我注意到Intellij的SequenceDiagram插件也是一个不错的选择。

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

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。

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。
