从@WebService带注释的EJB访问@SessionScoped bean

标签： soap ejb glassfish-3 cdi

我的一个合作伙伴需要一个SOAP接口，所以我想：让我们转移到一个应用服务器。我选择了Glassfish，开箱即用。我无法做到这一点：将@SessionScoped ManagedBean注入@Webservice带注释的EJB。

我可以访问EJB的唯一方法是通过JNDI。我读到了它here

我的问题是：Glassfish中是否存在错误，它将在未来版本中运行，或者它是否有效并且我做错了什么。

我希望能够使用DataAccess session注释注入属性@EJB，但它不起作用。

以下是测试项目中的所有文件

这是我的WebService类：

@LocalBean
@Stateless
@WebService()
public class MySOAP implements Serializable {

   private DataAccess session;

   @WebMethod
   public String getUsername() {
      javax.naming.Context ctx = null;
      try {
         ctx = new javax.naming.InitialContext();
         session = ( DataAccess ) ctx.lookup( "java:comp/env/DataAccess" );
         return "user is " + session.getData();
      } catch ( NamingException e ) {
         e.printStackTrace();
      }
      return "exception occured";
   }
}

我想注入的EJB：

public abstract class AbstractDataBean {
   @Inject /* this just returns some text*/
   private MySessionBean session;

   public MySessionBean getSession() {
      return session;
   }
}

@LocalBean
@Stateless
public class DataAccess extends AbstractDataBean implements Serializable {

   public String getData() {
      return " data " + getSession();
   }

   @Override
   public String toString() {
      return getData();
   }
}

@Named
@SessionScoped
public class MySessionBean implements Serializable {
   static private int classCounter = 0;
   private String user;

   @PostConstruct
   public void initMySessionBean( ) {
      user = "Micha " + (++classCounter) ; //to check how many times it was called
   }

   public String getUser() {
      return user;
   }

   public void setUser( String user ) {
      this.user = user;
   }

   @Override
   public String toString() {
      return user;
   }
}

我有一个用于定义JNDI的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

   <session-config>
      <session-timeout>1</session-timeout>
   </session-config>

   <ejb-local-ref>
      <ejb-ref-name>DataAccess</ejb-ref-name>
      <ejb-ref-type>Session</ejb-ref-type>
      <local>ch.sertal.server.services.ejb.DataAccess</local>
   </ejb-local-ref>

</web-app>

sun-jaxws.xml定义SOAP WebService：

<?xml version="1.0" encoding="UTF-8"?>
<endpoints xmlns='http://java.sun.com/xml/ns/jax-ws/ri/runtime' version='2.0'>

   <endpoint
               name='Mysoap'
               implementation='ch.sertal.server.services.MySOAP'
               url-pattern='/soap/Mysoap '/>
</endpoints>

和一个空的beans.xml以使CDI正常运行：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee 
        http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
</beans>

最后是pom.xml它很长，因为我从现有项目中复制了它。但是应该没有什么遗漏。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

免除建议，我不会切换到JBoss： - ）

1 个答案:

答案 0 :(得分：5)

对于JSR 299的6.7.2节，Web会话的会话范围不活跃，这不是错误。如果您考虑一下，没有太多意义，因为会话实际上并不是从一个Web服务请求到另一个Web服务请求。

另外，你说你出于好奇，你不会切换到JBoss，你的原因是什么？
