Question

将Java EE应用程序部署到WildFly时遇到问题我尝试了不同的方式。

我通过maven archetype创建了java应用程序（wildfly-javaee7-webapp-ear-archetype）并尝试通过Idea（和管理控制台）运行Wildfy，但得到了错误部署：

Cannot upload deployment: {"WFLYCTL0080: Failed services" => {"jboss.deployment.subunit.\"dtest-ear.ear\".\"dtest-ejb.jar\".POST_MODULE" => "org.jboss.msc.service.StartException in service jboss.deployment.subunit.\"dtest-ear.ear\".\"dtest-ejb.jar\".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of subdeployment \"dtest-ejb.jar\" of deployment \"dtest-ear.ear\" Caused by: java.lang.RuntimeException: WFLYSRV0177: Error getting reflective information for class by.mass.service.MemberRegistration with ClassLoader ModuleClassLoader for Module \"deployment.dtest-ear.ear.dtest-ejb.jar:main\" from Service Module Loader Caused by: java.lang.NoClassDefFoundError: Ljavax/enterprise/event/Event; Caused by: java.lang.ClassNotFoundException: javax.enterprise.event.Event from [Module \"deployment.dtest-ear.ear.dtest-ejb.jar:main\" from Service Module Loader]"}}

在日志中：

我不知道为什么cdi-api.jar不使用野生蝇罐。

<dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <scope>provided</scope>
    </dependency>

我删除了 - 提供。（cdi-api.jar打包到app.ear）并且应用程序将在Wildfly上运行。但是在调用http://localhost:7001/dtest-web/rest/members之后我有ERROR，因为所有@Inject对象都为null。

ERROR [io.undertow.request] (default task-5) UT005023: Exception handling request to /dtest-web/rest/members: org.jboss.resteasy.spi.UnhandledException: java.lang.NullPointerException

发生了什么事？任何人都可以拥有最小的REST + EJB示例吗？

@Path("/members")
@RequestScoped
public class MemberResourceRESTService {
@Inject
private Logger log;

@Inject
private Validator validator;

@Inject
private MemberRepository repository;

@Inject
MemberRegistration registration;

@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Member> listAllMembers() {
    return repository.findAllOrderedByName();
}

@GET
@Path("/{id:[0-9][0-9]*}")
@Produces(MediaType.APPLICATION_JSON)
public Member lookupMemberById(@PathParam("id") long id) {
    Member member = repository.findById(id);
    if (member == null) {
        throw new WebApplicationException(Response.Status.NOT_FOUND);
    }
    return member;
}

似乎是部署的问题。

我无法直接解决您的问题，但最简单的解决方案可能是将部署模型从EAR更改为WAR存档。

PS。另外请确保您没有使用不稳定的WildFly版本。

java.lang.ClassNotFoundException：javax.enterprise.event.Event
