EntityManagerFactory已关闭

问题描述

我正在尝试自动关联非Spring管理的类的依赖项.为此，我使用以下

I'm trying to autowire dependencies on a class that is not managed by Spring.To do that I use the following

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

    context.refresh();
}

此实例依赖于服务，依赖于存储库(由Spring数据JPA管理).

This instance has a dependency on a service, which has a dependency on a repository (managed by Spring data JPA).

问题是:当我尝试执行findOne操作时，出现此异常

Problem is : when I try to perform a findOne operation, I get this Exception

当我尝试使用entityManagerFactory时，它似乎已经关闭(或者可能从未打开过?).

The entityManagerFactory seems to be already closed (or maybe never opened?) when I try to use it.

当我手动为课程自动接线时，您是否知道如何打开此EntityManagerFactory的线索?

Do you have a clue on how to get this EntityManagerFactory open when I manually autowire the class?

推荐答案

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

As pointed out by M. Deinum, I was creating a new ApplicationContext instead of getting the existing one.

我更新了代码，使其看起来像这样

I updated my code to look like this

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

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

ApplicationContextProvider的位置如下:

public class ApplicationContextProvider implements ApplicationContextAware {

    private static ApplicationContext context;

    public ApplicationContext getApplicationContext() {
        return context;
    }

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

这很好，因为我得到了先前初始化的EntityManagerFactory.

This works fine, as I get the previously initialized EntityManagerFactory.
