“IllegalArgumentException：无法将[EJB接口]字段[managed bean field]设置为com.sun.proxy。$ Proxy [some number]”with OmniFaces''Eager

标签： jsf java-ee wildfly omnifaces payara

在多模块Maven Java EE 7项目中将EJB注入JSF托管bean在Payara 4.x和5.x以及Glassfish 4.x和5.x以及WildFly 11.0.0.Final上都失败了这让我觉得这不是我最初认为的Payara / Glassfish错误[1]。

WAR模块中的一个简单的JSF支持bean 

@Named
@ApplicationScoped
@Eager
public class Init {
    @EJB
    private InitService initService;

    public Init() {
    }

    @PostConstruct
    public void init() {
        initService.init();
    }
}

使用JAR模块中的EJB接口

@Local
public interface InitService {

    void init();
}

以及EJB模块中的实现

@Stateless
public class DefaultInitService implements InitService {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void init() {
        Long id = 1L;
        MyEntity myEntity0 = entityManager.find(MyEntity.class, id);
        if(myEntity0 == null) {
            myEntity0 = new MyEntity(Long.MIN_VALUE, "myProperty");
            entityManager.persist(myEntity0);
        }
    }
}
由于

因Payara 4.1.2.174而失败

这是How to use OmniFaces @Eager annotation with PrimeFaces?之前的，但不一样，因为在该问题中，即使正确配置了日志记录，我也没有得到任何异常或其他反馈。

通过引用的问题（不同分支上的不同AS和相应CI管道部分的输出）可以轻松找到在普通泊坞窗图像上重现问题的示例项目和GitLab CI输出

[1]在https://github.com/payara/Payara/issues/2237和https://github.com/javaee/glassfish/issues/22401报告了一个更简化的示例，该示例与代理类强制转换异常相关，但堆栈中没有涉及焊接。

1 个答案:

答案 0 :(得分：2)

...Proxy类强制转换异常问题是由WEB模块中的JAR模块的Maven compile范围（包含与EJB实现的WEB和EJB模块旁边的实体和EJB接口）产生的。这导致EJB接口类由不同的类加载器加载（这在Java EE设置中是正确的），因此根据类加载器的工作方式将它们视为不同的类。

通过将范围更改为WEB模块中的provided而没有任何缺陷，可以避免此问题。

应用程序服务器（GlassFish和WildFly以及可能还有其他人）的反馈非常糟糕，因为有许多（Java EE）技术，我提出了改进建议，尽管我明白了如果你的应用程序正常工作的黄金法则'完成了20％的工作，现在你需要处理剩余的80％，以便在所有可能的情况下获得有用的反馈，这需要一些时间（意味着几十年）才能实现。
