我的应用程序部署在JOnAS 5.2.2CDI支持EJB. 我需要使用CDIEJB。我知道如何CDI在应用程序的 WAR 部分上使用,但我部分不知道EJB

有没有办法在不支持的容器中添加CDI对应用程序的支持?EJB

我的老板不会为支持它的版本升级服务器。

[编辑] 我使用 CDI-WELD:我找到了解决方案的开始:

    //CDI uses an AnnotatedType object to read the annotations of a class
    AnnotatedType<DAOTest> type = beanManager.createAnnotatedType(DAOTest.class);
    //The extension uses an InjectionTarget to delegate instantiation, dependency injection 
    //and lifecycle callbacks to the CDI container
    InjectionTarget<DAOTest> it = beanManager.createInjectionTarget(type);
    //each instance needs its own CDI CreationalContext
    CreationalContext ctx = beanManager.createCreationalContext(null);
    //instantiate the framework component and inject its dependencies
    test = it.produce(ctx);  //call the constructor
    System.out.println("instance" + test);
    it.inject(test, ctx);  //call initializer methods and perform field injection
    it.postConstruct(test);  //call the @PostConstruct method

    test.test();

    it.preDestroy(test);  //call the @PreDestroy method
    it.dispose(test);  //it is now safe to discard the instance
    ctx.release();  //clean up dependent objects

我已经像这样在 DAOTest 中注入另一个测试:

@Named
@Dependent
public class DAOTest implements Serializable {
private static final long serialVersionUID = 1L;


@Persitence(value = "CDI-ejb")
private EntityManager em;

@Inject 
private User user; 

public void test(){
    System.out.println(user.getName());

    em.getClass();
}

public EntityManager getEm() {

    return em;
}

public void setEm(EntityManager em) {
    this.em = em;
}

public DAOTest() {
    // TODO Auto-generated constructor stub
}

}

它可以工作,但是 EntityManager 不能用@PersistenceContext 解决。我想我必须使用 @Produce 注释,但我不明白怎么做。

您需要将 Deltaspike 与 BeanProvider 功能一起使用。
