尝试在我的测试中注入一个控制器，调用用户
@Component("user")
@Scope("view")
public class UserController
项目使用：
当在测试中注入控制器时，会收到一个异常null点，但是当在tomcat中部署系统时，没有发生这种错误。
public class SysViewScope implements Scope{
public static final String VIEW_SCOPE_CALLBACKS = "viewScope.callbacks";
public synchronized Object get(String name, ObjectFactory<?> objectFactory){
Object instance = this.getViewMap().get(name);
if (instance == null){
instance = objectFactory.getObject();
this.getViewMap().put(name, instance);
}
return instance;
}
public Object remove(String name){
Object instance = getViewMap().remove(name);
if (instance != null){
Map<String, Runnable> callbacks = (Map<String, Runnable>) getViewMap().
get(VIEW_SCOPE_CALLBACKS);
if (callbacks != null){
callbacks.remove(name);
}
}
return instance;
}
public void registerDestructionCallback(String name, Runnable runnable)
{
Map<String, Runnable> callbacks = (Map<String, Runnable>) getViewMap().
get(VIEW_SCOPE_CALLBACKS);
if (callbacks != null){
callbacks.put(name, runnable);
}
}
public Object resolveContextualObject(String name){
FacesContext facesContext = FacesContext.getCurrentInstance();
FacesRequestAttributes facesRequestAttributes = new FacesRequestAttributes(facesContext);
return facesRequestAttributes.resolveReference(name);
}
public String getConversationId(){
FacesContext facesContext = FacesContext.getCurrentInstance();
FacesRequestAttributes facesRequestAttributes = new FacesRequestAttributes(facesContext);
return facesRequestAttributes.getSessionId() + "-" + facesContext.getViewRoot().getViewId();
}
private Map<String, Object> getViewMap(){
return FacesContext.getCurrentInstance().getViewRoot().getViewMap();
}
}
参见我的班级考试
@Scope("singleton")
@Configuration("webappTest")
@ComponentScan

@Autowired
private WebApplicationContext webApplicationContext;
@Autowired
@Qualifier("chromeDriver")
private WebDriver driver;
@Qualifier("user")
@Autowired

@PostConstruct

{
LOG.info("init ..." + webApplicationContext.toString());
}

我为解决这个问题做了什么，FacesContext.getCurrentInstance（），不返回更多null？
