问题 I am working on Transaction Management application, and I am using Struts2.

Will a new ActionContext and ValueStack be created for every new action object?

问题 My questions are: 1) In Struts2, does every action object have its own corresponding ActionContext and ValueStack ? In other words, for every new request a new action object is created. Does this mean every time a new action object is created, a new ActionContext and ValueStack also get created? 2) Consider this scenario: Action1------1st req------->view.jsp------2nd req--------->action2 So when a request comes for action1 a new object of action1 and corresponding ActionContext and ValueStack

What's the purpose of storing objects directly to the ValueStack/ActionContext?

问题 Based from what I've researched, I've seen that tags such as <s:set> , <s:push> or by creating an <s:bean> are able to insert references directly to the ActionContext or ValueStack . This confuses me a lot because why can't you just have one dedicated place to store everything? Probably just put everything in the ActionContext since it's basically acts as a ServletContext . To make it even more confusing, if you wanted to access values in the ValueStack , you'll have to use Struts tags such

问题 I'm using a custom interceptor which creates a new db connection, and sets this connection onto the current action before executing the action. After that, the interceptor closes the connection. I'm looking for a convenient way to share this db connection with other classes / static methods (such as Models) that are used by the action. E.g so I can call static method like User.get( id ) or User.getEmail( id ) without having to pass the db connection to each method separately. I could set the

Should I get the session through SessionAware or ActionContext?

由 假装没事ソ 提交于 2019-12-07 10:06:51
问题 After reading the differences between obtaining the session map via ActionContext.getContext().getSession() and having it injected through SessionAware I was wondering which is the preferred method, and why? The API recomends to use SessionAware , and I read on the web that using SessionAware makes the application easier to test--is testing the only issue? Can someone elaborate a little bit on this subject or point out to references explaining this? 回答1: I have already replied the same in
