依赖注入在使用 Jersey 和 OpenWebBeans 的 Tomcat 7 上不起作用

【中文标题】依赖注入在使用 Jersey 和 OpenWebBeans 的 Tomcat 7 上不起作用【英文标题】：Dependency Injection won't work on Tomcat 7 using Jersey and OpenWebBeans 【发布时间】：2012-04-07 04:32:58 【问题描述】：

我有点被我的问题困住了。我尝试使用 Jersey 运行 RESTful Web 服务，并将其与使用 Tomcat7 上的 OpenWebBeans 的一些依赖注入结合起来。 Jersey 部分本身似乎运行良好，但是当我创建 beans.xml 文件时，我得到了下面提到的错误......

所以我们开始：

我在 Eclipse 中使用 Maven 创建了项目：

文件->新建->其他->Maven项目->maven-archetype-webapp 并添加了 src/main/java 文件夹

文件树如下所示：

TJOWB |-部署描述符 |-Java 资源 |---src/main/资源 |-----META-INF |-------beans.xml |---src/main/java |-----a.b.c |-------Greeting.java |-------Hello.java |---图书馆 |-javascript 资源 |-部署资源 |-pom.xml |-src |-主要 |---java |---资源 |-----META-INF |-------beans.xml |---网络应用 |-----index.jsp |-----WEB-INF |-------beans.xml |-------web.xml |-目标

pom.xml 文件：

添加到

Tomcat /lib:

geronimo-atinject_1.0_spec-1.0.jar geronimo-interceptor_1.1_spec-1.0.jar geronimo-interceptor_3.0_spech-1.0.jar geronimo-jcdi_1.0_spec-1.0.jar javassist_3.12.1.GA.jar openwebbeans-impl-1.1.3.jar openwebbeans-resource-1.1.3.jar openwebbeans-spi-1.1.3.jar openwebbeans-tomcat7-1.1.3.jar openwebbeans-web-1.1.3.jar scannotation-1.0.2.jar

在 Tomcat /conf/server.xml 中

Listener className="org.apache.webbeans.web.tomcat.ContextLifecycleListener" /

你好.java：

package a.b.c;

import javax.annotation.ManagedBean; 
import javax.annotation.PostConstruct; 
import javax.inject.Inject; 
import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 

@Path("inject") 
public class Hello 

    @Inject
    private Greeting mGreeting;

    public Hello() 

    

    @PostConstruct
    public void init() 

    

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayPlainTextHello() 
       if (mGreeting != null)
            return mGreeting.greetUser();
        else
            return "Dependency Injection failed";

问候.java：

package a.b.c;

public class Greeting 

    public String greetUser() 
        return "Hello";

所以，现在是实际的错误消息：

如果 src/main/webapp/WEB-INF 中没有 beans.xml，则应用程序可以正常工作。至少它开始了，泽西岛起作用了；）

但是一旦我创建了 beans.xml（（我必须这样做，我想）bean.xml 只包含我无法在此处显示的 beans 标签（因为我不知道如何），否则是 emtpy ) 我得到以下堆栈跟踪：

【问题讨论】：

你解决了吗？我遇到了同样的问题。 如果你在 github 上有一些示例应用程序，那么我会看看你的设置。 【参考方案1】：

请从这里阅读我的帖子以查看第一个问题的解决方案： Attempting to use Jersey (JAX-RS) and Weld (CDI) in Tomcat 7. Getting noClassDefFoundError for javax.annotation.ManagedBean.

请确保为 tomcat 引导 CDI 的方式是正确的：这是一个非常有用的资源：@​​987654322@

好的，我也遇到了同样的问题，解决方法很简单（虽然调试了半天）

只需使用 @ManagedBean 注释您的 Hello 类

以上是关于依赖注入在使用 Jersey 和 OpenWebBeans 的 Tomcat 7 上不起作用的主要内容，如果未能解决你的问题，请参考以下文章

使用 jersey 测试框架时 Servlet 上下文注入失败

让 Spring 了解 Jersey 过滤器

jersey 2.2 和 Spring Security 3 依赖项？

在 jersey 项目中包含 jersey-bom 导入范围依赖项的目的是啥？

将对象注入过滤器

我是不是需要服务器端的“jersey-client”依赖项来支持使用它实现的客户端？
