Generate UML Class Diagram from Java Project [closed]

由 我是研究僧i 提交于 2019-11-26 12:15:27
问题 Is there a good tool that can help to reverse engineer Java classes to UML that will show an overview of how my classes are related to each other? It doesn\'t need to decompile from JAR file because I have the sources. I know there are quite a few out there but most of those can only generate individual class. I hope there is a tool that can generate class diagram that shows an overview of how all my current classes and packages work together, so that I can analyse my current architecture

问题 I tried (though not very comprehensively) numerous solutions including ModelGoon (only class and interaction diagrams available), ObjectAid (class diagram only), eUML free edition (quits with an ominous \"license not found\" error on first use), MoDisco (with the only option on the menu being \"browse corresponding model element\"). And also some standalone tools - ArgoUML and BOUML either dont provide this feature or at least i was not able to find it. Jsonde started only after i fixed a

Is it necessary to include the login for every usecase?

问题 iam going to design a system that has a login facility. After login the logged user can do several things so is it needs to include login usecase by that several usecases. 回答1: In most cases, it will only clutter up your diagrams. Login is neither complex nor does it give you much added value as a use case. In your textual document that includes the use cases with description, include as a prerequisite a list of features that require a successful login. Easier to track and to test. 来源： https:

问题 7.3.3 Association(from kernel) ,page 36,UML superstructure ,v2.4.1: an association either owned by classifier or by relationship. Is there a real-life example in UML about association owned by classifier and association owned by relationship? 回答1: Chriss I hope this simple example helps. Guess you have a Java class public class A { private B b; ... } In UML you would model this relationship as an association from A to B: A -> B with the following modeling elements: Class B Class A + Property

问题 Hello I have a few questions about UML class diagrams any help will be appreciated 1) How do you show pointers in attributes? 2) Whats multiplicity? 3) What direction should the composition arrows be? 4) How do you put enums? 回答1: According to the current UML standard 2.4.1 and the next one 2.5 (it differs almost only in more simple documentation): Pointers/references should be shown as arrow with small black circle (dot) at the referenced end.
