Question

我尝试将我的应用程序版本从Hybris 4.8迁移到Hybris 5.6.0.5。

当服务器启动时，我有这个例外：

JSONObject jsonObject = new JSONObject("jsonResponse");
    JSONArray jsonArr= jsonObj.getJSONArray("destination_addresses");
    String[] arrDestinations=new String[jsonArr.lLength()];
    for(int i=0;i<jsonArr.length();i++)
        arrDestinations[i]=jsonArr.get(i);

    jsonArr= jsonObj.getJSONArray("origin_addresses");
    String[] arrOrigins=new String[jsonArr.lLength()];
    for(int i=0;i<jsonArr.length();i++)
        arrOrigins[i]=jsonArr.get(i);

    JSONArray rows = jsonObj.getJSONArray("rows");
    for(int i =0; i < rows.length(); i++)
    {
        JSONObject rowObj = rows.getJSONObject(i);
        JSONArray rowElements = rowObj.getJSONArray("elements");
        for(int element = 0; element < rowElements.length(); element++) {
               // get the elements and parse
        }
    }

因为在FlexSelector类中：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'csTicketFacade' defined in class path resource [CoopAcceleratorFrontEndfacades-spring.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class  [com.accenture.hybris.facades.customerservice.impl.CoopCSTicketFacade]: Constructor threw exception; nested exception is java.lang.NullPointerException

spring的应用程序上下文为null。如果有人有任何想法，请告诉我。

Answer 1

对应用程序上下文进行静态引用并不是一个好主意。相反，正如@thijsraets建议你应该为flexSelector bean实现ApplicationContextAware创建类。 E.g：

public class FlexSelector implements ApplicationContextAware  {
    ApplicationContext context;
    public ApplicationContext getContext() {
        return context;
    }
    @Override
    public void setApplicationContext(ApplicationContext context)
            throws BeansException {
        this.context=context;
    }
    [...]
}

这将确保在Spring连接bean时设置应用程序上下文。

如果您在FlexSelector中有静态方法并且需要应用程序上下文，则应始终通过Registry.getApplicationContext()调用在静态方法中动态查找，而不是将其存储在静态变量中

你真的只需要applicationContext对象吗？如果你只需要检索bean，你可以像下面这样做：

final ManagerFactoryBean managerFactoryBean =（ManagerFactoryBean）Registry.getApplicationContext（）。getBean（“managerFactoryBean”）;

我也在hybris工作，这就是我的bean引用方式。
