和我的服务等级

@Path("generic")
public class GenericResource {

    @Context
    private UriInfo context;

    /**
     * Creates a new instance of GenericResource
     */
    public GenericResource() {
    }

    /**
     * Retrieves representation of an instance of com.trianz.travapp.service.web.GenericResource
     * @return an instance of java.lang.String
     */
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String getJson() {
        return "Server Test Web Serives";
    }

    /**
     * PUT method for updating or creating an instance of GenericResource
     * @param content representation for the resource
     */
    @PUT
    @Consumes(MediaType.APPLICATION_JSON)
    public void putJson(String content) {
    }
}

但是tomcat类显示错误消息，如下所示：java.lang.ClassNotFoundException：com.sun.jersey.spi.spring.container.servlet.SpringServlet

在部署时。

我想念什么？

Answer 1

该错误表明您缺少com.sun.jersey.spi.spring.container.servlet.SpringServlet类，我认为这是您声明的jar中的一个类： <groupId>com.sun.jersey.contribs</groupId> <artifactId>jersey-spring</artifactId> <version>1.19</version>您应该在此jar中验证您的类是否存在？ 如果不是您的jersey其他版本

Answer 2

如果您使用的是jersey 2.x，则实际上取决于jersey版本，则需要在web.xml中进行其他配置。 您可以使用以下配置更新web.xml。

 <servlet>
    <servlet-name>myrest</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>    
    <init-param>
      <param-name>jersey.config.server.provider.packages</param-name>
      <param-value>your.package.path</param-value>
    </init-param>
    <init-param>
     <param-name>unit:WidgetPU</param-name>
     <param-value>persistence/widget</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>myrest</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>

看这里
