Question

我有Jersey REST Web资源和一个注入的Singletone EJB。

一切正常，但是我在JUnit测试中出现问题：

我尝试通过@EJB测试使用注入的单调Bean的Jersey资源（REST服务），并在Resource尝试使用Bean测试时崩溃并显示错误。

资源类：

public class UserResource {
    @EJB
    Models models;

    @GET
    @Path("/test")
    @Produces(MediaType.APPLICATION_JSON)
    public User testUser(){

        return models.getUser(1);
    }
}

测试：

public class UserTest extends JerseyTest {

    @Override
    protected Application configure() {
        return new ResourceConfig(UserResource.class, Models.class);
    }

    @Test
    public void test() throws Exception {

        User u = target("/ws/users/test").request().get(User.class);

        Assert.assertNotNull(u.getId());
    }
}

beans.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>

我使用：

JUnit 4.12
glassfish-embedded 4.1.1
javaee-api 7.0

我错过了什么？有办法使它起作用吗？
