ObjectAid UML Explorer

是我用的。它很容易从存储库安装:

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.

我会推荐Omondo的EclipseUML作为一般使用，尽管几个月前我的web项目确实遇到了一些问题。他们曾经有过一个免费版本，但据说已经不再推广了。

如果你真的热衷于从源代码逆向工程序列图，我推荐jTracert。

就Eclipse项目本身而言，Eclipse UML2 Tools项目可能支持逆向工程，尽管我从未见过它在实践中的使用。

MoDisco(模型发现)项目Eclipse GMT项目似乎更清楚地实现了您的目标。特定于技术的工具列表将是一个很好的开始。

有一个名为binarydoc的免费工具，它可以从Java方法的字节码(而不是源代码)生成UML序列图或控制流图(CFG)。

下面是为java方法java.net.AbstractPlainSocketImpl.getInputStream生成的示例图binarydoc:

方法控制流图:

方法的UML序列图:

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。

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。
