an odd problem about struts2 annotation
hi,everyone
I meet an odd problem with struts2 annotation,Let me elaborate it first
import java.util.List;
import lombok.Getter;
import lombok.Setter;
import org.apache.commons.lang.StringUtils;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import org.apache.struts2.interceptor.validation.SkipValidation;
import org.springframework.beans.factory.annotation.Autowired;
import com.dbappsecurity.portal.model.PortalUser;
import com.dbappsecurity.portal.service.PortalUserService;
import com.opensymphony.xwork2.ActionSupport;
@Results({
@Result(name="input",location="main.jsp"),
@Result(name="list",location="list.jsp")
})
public class MainAction extends ActionSupport {
@Getter @Setter private PortalUser user;
@Autowired
private PortalUserService portalUserService;
public String execute() throws Exception {
return INPUT;
}
@Action("addUser")
public String addUser() throws Exception {
portalUserService.addUser(user);
return listUser();
}
@Action("listUser")
@SkipValidation
public String listUser() throws Exception {
List theUserList = portalUserService.getPortalUserList(null);
ServletActionContext.getRequest().setAttribute("userList",theUserList);
return "list";
}
@Action("modifyUser")
public String modifyUser() throws Exception {
List theUserList = portalUserService.getPortalUserList(null);
ServletActionContext.getRequest().setAttribute("userList",theUserList);
return "list";
}
this is the struts2 action class, I configure it correctly and type the url
http://domain/listUser it will list all users
http://domain/modifyUser it can modify the users
all things go well in tomcat with exploded class files
but when I build with the war file and deploy it into tomcat webapp folder,
the page report
there is no action name listUser
the difference between the two scenario is exploded class files and archived
class files that I compile and jar the action and other class files into it.
I was puzzled about this phenomenon
so any suggestions and advices will be very appreciated!

Is your Tomcat configured for autodeploy=true?

for one reason is that struts2 will not scan your classes in jar is that if
someone tempered with you jar or any of your jar has class with Struts
Annotations then your user can access these actions without you knowing it.
I believe this is the same reason why Spring doesnt scan files in jars and
in order to use them you have to declare them explicitly in xml files.

Re: an odd problem about struts2 annotation

I know some tricky about this problem
the struts convention will scan action class in the specific package
for example:
struts.convention.package.locators indicate the action class suffix
but when you jar the classes,I suppose that struts2 can't scan the action
class
in jar files,if this is true,I will always deploy war with class files
exploded,I want to find
a workaround,thanks

I jar the classes and put it into WEB-INF/lib
of course you know,the war will package all jars and jsp files in bundle
why the struts2 can't scan classes in WEB-INF/lib?

sorry just to be clear
did you "jar" the classes or did you "war" the classes?
if you "jar" the classes then i dont think struts 2 will scan your classes
in jars.
