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

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.

PlantUML怎么样? 这不是逆向工程!!这是在编码之前的工程设计。

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。

使用IntelliJ IDEA。要生成类图，选择package并按Ctrl + Alt + U:

默认情况下，它只显示类名，而不显示所有依赖项。要更改它:右键单击->显示类别…和显示依赖项:

要生成依赖关系图(UML部署图)，使用maven go View -> Tool Windows -> maven Projects，并按Ctrl + Alt + U:

结果:

此外，还可以生成更多其他图表。见文档。
