将Jersey 2和Spring与基于Java的配置集成

Question

我正在使用Jersey 2.10和jersey-spring3以及Spring 4.我想在泽西资源以及其他地方实现DI(基本上是服务)并且想要通过Java配置创建Spring Beans.

目前,我无法找到任何方法来做到这一点.知道怎么做吗？

我的web.xml看起来像这样

<web-app>
    <display-name>Restful Web Application</display-name>
    <servlet>
        <servlet-name>jersey-serlvet</servlet-name>
        <servlet-class>
             org.glassfish.jersey.servlet.ServletContainer 

        </servlet-class>
        <init-param>
            <param-name>
                jersey.config.server.provider.packages
            </param-name>
            <param-value>com.xyz</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/application-context.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet-mapping>
        <servlet-name>jersey-serlvet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

web应用程序:

<context-param>
    <param-name>contextClass</param-name>
    <param-value>
      org.springframework.web.context.support.AnnotationConfigWebApplicationContext
  </param-value>
</context-param>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>xxx.xxx.configuration.ApplicationConfiguration</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>SpringApplication</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>xxx.xxx.controllers.HelloController</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>SpringApplication</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

基于Java的配置:

@Configuration
public class ApplicationConfiguration {
  @Bean
  HelloService helloService () {
    return new HelloServiceImpl();
  }
}

和简单的控制器:

@Component
@Path("/helloController")
public class HelloController {

  @Autowired
  @Qualifier("helloService")
  private HelloService helloService ;


   @GET
   @Path("/hello")
   public String hello() {
    helloService.service();
  }
}

用于检测:

本地主机:8080/[AppName的]/HelloController中/你好

记住要排除旧的Spring依赖项,如果不这样做,可能会有一些冲突.您可以像下面的示例或通过DependencyManagement一样执行此操作.
