将EJB 3注入Spring Bean [英] Injecting EJB 3 into Spring Bean

问题描述

我正在尝试将EJB注入Spring(3.1.2)服务(均在不同 WAR中) 两者都很简单(删除了方法以简化示例):

I am trying to inject EJB into Spring (3.1.2) service (both in different WARs) Both are very simple (methods removed to simplify example):

EJB:

@Remote
public interface MyBean {
}

@Singleton
public class MyBeanImpl implements MyBean{
}

服务:

@Service
public class MyServiceImpl implements MyService{
}

乍一看，事情很简单，但我尝试过:

At first sight thing is very simple, but I tried:

@EJB(lookup = "java:global/ejbApp/MyBeanImpl!com.my.MyBean")
private MyBean myBean;

，它不起作用.然后我也尝试了:

and it didin't work. Then I also tried:

@EJB(mappedName = "java:global/ejbApp/MyBeanImpl!com.my.MyBean")
private MyBean myBean;

还有

@Resource(mappedName = "java:global/ejbApp/MyBeanImpl!com.my.MyBean")
private MyBean myBean;

但都不起作用.

我设法使用以下方法注入了EJB:

I managed to inject my EJB using:

<jee:jndi-lookup id="myBean" jndi-name="java:global/ejbApp/MyBeanImpl!com.my.MyBean" />

在我的spring配置和服务中:

in my spring configuration and in the service:

@Autowired
private MyBean myBean;

但是我真的不喜欢这种解决方案.我想在 some 批注中添加我的JNDI路径，例如:

But I really dont like this solution. I would like to have my JNDI path in some annotation to be able to do e.g:

@EJB(lookup = MyBean.JNDI_NAME)
private MyBean myBean;

推荐答案

我们已经找到了非常简单的解决方案. 放入spring配置文件中，必须放入:

We have found quite nice and simple solution. Into spring configuration file one has to put:

<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor">
    <property name="alwaysUseJndiLookup" value="true" />
</bean>

这使spring可以在JNDI中搜索用@Resource注释的 beans . 所以现在可以做到:

And that enables spring to search for the beans annotated with @Resource in JNDI. So now one can do:

@Resource(mappedName = MyBean.JNDI_NAME)
private MyBean myBean;
