EntityManagerFactory已关闭

Question

我试图在不受Spring管理的类上自动依赖依赖关系。 为此，我使用以下

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，该服务依赖于存储库（由Spring数据JPA管理）。

问题是：当我尝试执行findOne操作时，我得到此异常

当我尝试使用它时，entityManagerFactory似乎已经关闭（或者可能永远不会打开？）。

当我手动自动挂载课程时，您是否知道如何让EntityManagerFactory打开？

Answer 1

正如M. Deinum指出的那样，我正在创建一个新的ApplicationContext，而不是获取现有的ApplicationContextProvider appContextProvider = new ApplicationContextProvider(); ApplicationContext applicationContext = appContextProvider.getApplicationContext(); AutowireCapableBeanFactory factory = applicationContext.getAutowireCapableBeanFactory(); factory.autowireBean(this); factory.initializeBean(this, "logJaxSoapMessageHandler"); 。

我将代码更新为

ApplicationContextProvider

public class ApplicationContextProvider implements ApplicationContextAware { private static ApplicationContext context; public ApplicationContext getApplicationContext() { return context; } @Override public void setApplicationContext(ApplicationContext ac) throws BeansException { context = ac; } } 看起来像这样：

EntityManagerFactory

这很好，因为我得到了之前初始化的 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.passbook); TableLayout tl = (TableLayout) findViewById(R.id.mytable); tl.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //obj.myShow(Passbook.this, v.getTag() + ": Row is clicked" ); } }); } 。
