java - EntityManagerFactory 已关闭

Question

我正在尝试 Autowiring 对不受 Spring 管理的类的依赖关系。为此，我使用以下内容

try (ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml")) {
    AutowireCapableBeanFactory factory = context.getAutowireCapableBeanFactory();
    factory.autowireBean(this);
    factory.initializeBean(this, "logJaxSoapMessageHandler");

    context.refresh();
}

该实例依赖于一个服务，而该服务又依赖于一个存储库(由 Spring data JPA 管理)。

问题是:当我尝试执行 findOne 操作时，出现此异常

当我尝试使用它时，entityManagerFactory 似乎已经关闭(或者可能从未打开？)。

当我手动 Autowiring 类时，您知道如何打开这个 EntityManagerFactory 吗？

Answer 1

正如 M. Deinum 所指出的，我正在创建一个新的 ApplicationContext 而不是获取现有的。

我更新了我的代码，如下所示

ApplicationContextProvider appContextProvider = new ApplicationContextProvider();
ApplicationContext applicationContext = appContextProvider.getApplicationContext();

AutowireCapableBeanFactory factory = applicationContext.getAutowireCapableBeanFactory();
factory.autowireBean(this);
factory.initializeBean(this, "logJaxSoapMessageHandler");

其中 ApplicationContextProvider 如下所示:

public class ApplicationContextProvider implements ApplicationContextAware {

    private static ApplicationContext context;

    public ApplicationContext getApplicationContext() {
        return context;
    }

    @Override
    public void setApplicationContext(ApplicationContext ac)
        throws BeansException {
        context = ac;
    }
}

这工作正常，因为我得到了之前初始化的EntityManagerFactory。
