Lukasz Lenart commented on WW-4903:
-----------------------------------
The simplest workaround is to use the below code to implement your own
{{ActionProxyFactory}}
{code:java}
public class MyPrefixBasedActionProxyFactory extends DefaultActionProxyFactory {
private static final Logger LOG =
LogManager.getLogger(MyPrefixBasedActionProxyFactory.class);
private Map<String, ActionProxyFactory> actionProxyFactories = new
HashMap<>();
@Inject
public void setContainer(Container container) {
this.container = container;
}
@Inject(StrutsConstants.PREFIX_BASED_MAPPER_CONFIGURATION)
public void setPrefixBasedActionProxyFactories(String list) {
if (list != null) {
String[] factories = list.split(",");
for (String factory : factories) {
String[] thisFactory = factory.split(":");
if (thisFactory.length == 2) {
String factoryPrefix = thisFactory[0].trim();
String factoryName = thisFactory[1].trim();
ActionProxyFactory obj =
container.getInstance(ActionProxyFactory.class, factoryName);
if (obj != null) {
actionProxyFactories.put(factoryPrefix, obj);
} else {
LOG.warn("Invalid PrefixBasedActionProxyFactory config
entry: [{}]", factory);
}
}
}
}
}
public ActionProxy createActionProxy(String namespace, String actionName,
String methodName,
Map<String, Object> extraContext,
boolean executeResult, boolean cleanupContext) {
String uri = namespace + (namespace.endsWith("/") ? actionName : "/" +
actionName);
for (int lastIndex = uri.lastIndexOf('/'); lastIndex > (-1); lastIndex
= uri.lastIndexOf('/', lastIndex - 1)) {
String key = uri.substring(0, lastIndex);
ActionProxyFactory actionProxyFactory =
actionProxyFactories.get(key);
if (actionProxyFactory != null) {
LOG.debug("Using ActionProxyFactory [{}] for prefix [{}]",
actionProxyFactory, key);
return actionProxyFactory.createActionProxy(namespace,
actionName, methodName, extraContext, executeResult, cleanupContext);
} else {
LOG.debug("No ActionProxyFactory defined for [{}]", key);
}
}
LOG.debug("Cannot find any matching ActionProxyFactory, falling back to
[{}]", super.getClass().getName());
return super.createActionProxy(namespace, actionName, methodName,
extraContext, executeResult, cleanupContext);
}
}
{code}
then register it in {{struts.xml}}:
{code:xml}
<bean type="com.opensymphony.xwork2.ActionProxyFactory" name="myPrefix"
class="com.company.MyPrefixBasedActionProxyFactory"/>
{code}
and use it in {{struts.xml}}
{code:xml}
<constant name="struts.actionProxyFactory" value="prefix"/>
{code}
