使用Ear / EJB / Web模块时，Glassfish 4.1无法运行RestFul服务

叶书
2023-03-14
问题内容：

我有很多使用RestFul服务的jee7 maven项目（带有Web和ejb模块的耳朵），它们在Glassfish v
4.0上运行良好，但是当我尝试在Glassfish v.4.1上运行这些项目时，RestFul服务就不再起作用他们抛出了这个异常：

javax.servlet.ServletException: A MultiException has 1 exceptions.  They are:
1. org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=TestBean,parent=GenericResource,qualifiers={},position=-1,optional=false,self=false,unqualified=null,82785107)

我已经仔细检查了这个问题，并确定Glassfish 4.1可能有一个损坏的库（也许是cdi实现？），Glassfish v.4.0和Wildfly
8.1.0.Final运行良好…

我不明白如何在Glassfish v.4.1上运行RestFul Web服务…

有人可以帮助我吗？

提前谢谢了…

这里是堆栈跟踪：

我有一个ejb模块和一个Web模块（该Web模块将ejb模块添加为库）。

ejb模块具有此类：

package test.session;
import javax.ejb.Stateless;
import javax.inject.Named;
@Stateless
@Named
public class TestBean {
  public String getValue() {
    return "value";
  }
}

Web模块具有以下类：

package test.rest;
import java.util.Set;
import javax.ws.rs.core.Application;
@javax.ws.rs.ApplicationPath("webresources")
public class ApplicationConfig extends Application {
  @Override
  public Set<Class<?>> getClasses() {
    Set<Class<?>> resources = new java.util.HashSet<>();
    addRestResourceClasses(resources);
    return resources;
  }
  private void addRestResourceClasses(Set<Class<?>> resources) {
    resources.add(test.rest.GenericResource.class);
  }
}

和：

package test.rest;
import javax.ejb.Stateless;
import javax.inject.Inject;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.UriInfo;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PUT;
import test.session.TestBean;
@Path("generic")
@Stateless
public class GenericResource {
  @Context
  private UriInfo context;
  @Inject
  TestBean testBean;
  public GenericResource() {
  }
  @GET
  @Produces("application/json")
  public String getXml() {
    //TODO return proper representation object
    return testBean.getValue();
 }
}

如果我尝试导航：

http://localhost:8080/TestRest/webresources/generic

Glassfish 4.1引发异常，Glassfish 4.0运作良好…


问题答案：

我有一个类似的问题。这是@ user993553提到的一个错误，它试图从EJB模块内部实例化WAR模块的EJB（GenericResource）。

解决方法是将EJB从WAR模块转换为CDI。只需更改@javax.ejb.Stateless为@javax.enterprise.context.RequestScoped或任何其他范围。

@Path("generic")
@javax.enterprise.context.RequestScoped
public class GenericResource 
{
    @Context
    private UriInfo context;

    @Inject
    TestBean testBean;

    public GenericResource() {}

    @GET
    @Produces("application/json")
    public String getXml() {
        // TODO return proper representation object
        return testBean.getValue();
    }
}
