Struts 2 and business objects

由 久未见 提交于 2019-12-10 12:18:16
问题 In a Struts 2 class where http get params are auto fetched by field variables. While there were repeated such class fields like userId,groupId, etc in many classes, I decided to make one business object class RequestParams in each class and put all the field there. Then all my class will have just the RequestParams rp; with getRp(); and setRp(); the rp class will have the userId with getters / setters and all other fields. Now I see I have to replace. e.g userId with getRp() . getUserId(); at

问题 Is there a cleaner way to do this in a JSP/Struts1 setup ? ... some HTML here ... EDIT: In admin mode I would like to have access to additional parameters from a form element, e.g. from the form element: input type="text" value="Test user" name="Owner" EDIT 2: Actually, my problem is very similar to the question that was asked in : Conditionally Render In JSP By User But I don't really get the "pseudo-code" from the likely answer 回答1: Is SessionConfig exposed as a bean in your JSP (as part of

Logging user actions

问题 The customer wants us to "log" the "actions" that a user performs on our system: creation, deletion and update, mostly. I already have an aspect that logs the trace, but that works at a pretty low level logging every method call. So if a user clicked on the button "open medical file" the log would read: closePreviousFiles("patient zero") createMedicalFile("patient zero") --> file #001 changeStatus("#001") --> open while the desired result is: opened medical file #001 for patient zero I'm

Is it possible to have a dynamic path as part of a jsp include

由 风流意气都作罢 提交于 2019-12-10 10:34:39

Struts2 action - test it or not?

由 只愿长相守 提交于 2019-12-10 10:01:33
问题 I'm currently working on one project, that uses Struts2 framework. We use separate component for DB accessing, which is well tested. At the same time, project, that we work on has a lot of Actions, that are not tested. In most of the actions we use at least one DB-service call. So on one hand these actions are pretty simple. I'm not sure - should unit tests be written for that or not? I think that good practice is write unit tests always, but these actions are so simple and I'm under big
