I'm trying to use the Spring plugin to inject a dependency into my action at runtime. This is the first time I've tried this with Struts2 so I may have missed something but I'm stumped because I can see the dependency is injected but then the object is later null when I need to use it. Here is my action class code:
public class UserRegisterAction extends ActionSupport { private User user = new User(); @Override public String execute(){ getUserService().saveUser(user); return "success"; } public UserServiceImpl getUserService(){ return userService; } UserServiceImpl userService; public void setUserService(UserServiceImpl us){ this.userService = us; } } Using the debugger I can see that upon startup "setUserService is called and this.userService is set, so the injection appears to be working ok, but when the execute method is called when the page is submitted userService is null. I'm quite new to Struts but I don't understand how my userService is being null. Can anyone see what I am missing?
