------------------------------
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
