Question

我正在尝试使用jersey创建一个嵌入jetty（而不是Java EE）的webserver，并使用REST来映射我的servlet。
我使用spring进行依赖注入，并将servlet映射为bean 但是，当我尝试对映射的servlet进行HTTP req时，我收到错误500服务器错误，或404，找不到页面。
我不确定我是否正确地这样做，我应该使用jetty.xml而不是这个。（想知道是否有使用jetty.xml的shorcut）

我在servlets包中有一个类：DoNothing.java

世界上我做错了什么？或者我应该问世界上我做得对吗？

谢谢

我一直在寻找使用Jersey + Spring + Embedded Jetty的方法，并找到了这个问题。我尝试了你的方法，它确实有效。

如果您想在资源中实际使用Spring bean，可以使用jersey-spring：

<bean id="server" class="org.mortbay.jetty.Server" destroy-method="stop">
    <property name="connectors">
        <list>
            <bean id="Connector" class="org.mortbay.jetty.nio.SelectChannelConnector">
                 <property name="port" value="8080"/>
            </bean>
        </list>
    </property>
    <property name="handlers">
        <list>
            <bean class="org.mortbay.jetty.servlet.Context">
                <property name="contextPath" value="/"/>
                <property name="sessionHandler">
                    <bean class="org.mortbay.jetty.servlet.SessionHandler" />
                </property>
                <property name="servletHandler">
                    <bean class="org.mortbay.jetty.servlet.ServletHandler">
                        <property name="servlets">
                            <list>
                                <bean class="org.mortbay.jetty.servlet.ServletHolder">
                                    <property name="name" value="jersey" />
                                    <property name="servlet">
                                        <bean class="com.sun.jersey.spi.spring.container.servlet.SpringServlet" />
                                    </property>
                                    <property name="initParameters">
                                         <map>
                                         <entry key="com.sun.jersey.spi.container.ContainerRequestFilters"
                                            value="com.sun.jersey.api.container.filter.LoggingFilter" />
                                        <entry key="com.sun.jersey.spi.container.ContainerResponseFilters"
                                            value="com.sun.jersey.api.container.filter.LoggingFilter" />
                                    </map>
                                    </property>

                                </bean>
                            </list>
                        </property>
                        <property name="servletMappings">
                            <list>
                                <bean class="org.mortbay.jetty.servlet.ServletMapping">
                                    <property name="servletName" value="jersey"/>
                                    <property name="pathSpecs">
                                        <list>
                                            <value>/*</value>
                                        </list>
                                    </property>
                                </bean>
                            </list>
                        </property>
                    </bean>
                </property>
                <property name="eventListeners">
                    <list>
                        <bean id="requestContextListener" class="org.springframework.web.context.request.RequestContextListener"/>
                        <bean id="contextLoaderListener" class="org.springframework.web.context.ContextLoaderListener"/>
                    </list>
                </property>
                <property name="initParams">
                    <map>
                        <entry key="contextConfigLocation" value="classpath:META-INF/AdditionalBeansContext.xml"/>
                    </map>
                </property>
            </bean><!--
        --></list>
    </property>
</bean>

在文件AdditionalBeansContext.xml中：

然后使用以下命令定义您的资源：@Component注释，使用@Autowired注入bean

可以组合：球衣+码头+弹簧
