我是Spring的新手，我正在尝试将Conversation Scope用于我的应用程序。
ConversationScopedBacking.java

public abstract class ConversationScopedBacking implements Serializable {

@Inject
private Conversation conversation;
public void beginConversation() {
if (conversation.isTransient()) {
conversation.begin();
}
}
public void endConversation() {
if (!conversation.isTransient()) {
conversation.end();
}
}
public String getConversationId() {
return conversation.getId();
}
protected boolean isTransient() {
return conversation.isTransient();
}
public void initialize() {
beginConversation();
}
protected void setFlashAttribute(final String key, final Object value) {
FacesContext.getCurrentInstance().getExternalContext().getFlash()
.put(key, value);
}
protected Object getFlashAttribute(final String key) {
return FacesContext.getCurrentInstance().getExternalContext()
.getFlash().get(key);
}
}
UserDepartmentBacking.java

}
public void onRowSelect(SelectEvent event) {

switch ((int)index) {

我收到了这个错误。
