zhouyong updated WW-4105:
-------------------------
Description:
java.lang.ClassCastException: A action cannot be cast to B action when A chain
to B.
ChainingInterceptor.java has a bug in intercept function when Result type is
chain.
Intercept function of ChainingInterceptor will change action member of
DefaultActionInvocation class. And invokeAction of DefaultActionInvocation will
fail in line 450.
My action class has a annotation. It is
org.springframework.transaction.annotation.Transactional. Action work good
if it has not org.springframework.transaction.annotation.Transactional
AtestAction.java:
package demo.action;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Transactional
@ParentPackage(value="swordlite")
@Service("AtestAction")
@Scope(value = "prototype")
@Results( {
@Result(name = "test", location = "testb", type = "chain",
params = {
"defineId", "${_defineId}",
"rp", "${_resultPage}"}
)
})
public class AtestAction {
@Action(value = "/testa")
public String run() throws Exception
{ return "test"; }
}
BtestAction.java:
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Transactional
@ParentPackage(value="swordlite")
@Service("BtestAction")
@Scope(value="prototype")
@Results({
@Result(name="ok", location="/ok.jsp", type="dispatcher"),
})
public class BtestAction {
@Action(value = "/testb")
public String run() throws Exception
{ return "ok"; }
}
request: http://localhost:8080/test/testa.action
raise error: java.lang.ClassCastException: demo.action.AtestAction cannot be
cast to demo.action.BtestAction
