服务资源的代码如下：

package com.example.annotation.method;
    
    import java.awt.List;
    import java.util.ArrayList;
    
    import javax.ws.rs.BeanParam;
    import javax.ws.rs.Consumes;
    import javax.ws.rs.DELETE;
    import javax.ws.rs.GET;
    import javax.ws.rs.POST;
    import javax.ws.rs.PUT;
    import javax.ws.rs.Path;
    import javax.ws.rs.Produces;
    import javax.ws.rs.QueryParam;
    import javax.ws.rs.core.MediaType;
    
    import com.example.domain.Book;
    
    //新加的，自己写的， get put delete post方法
    @Path("BookResourceget")
    public class BookResourceget { 
    
        //http://localhost:8080/simpleservice/webapi/BookResourceget/
        @GET
        @Produces(MediaType.APPLICATION_JSON)
        public Book getWeight(){
            Book book=new Book();
            book.setBookId(Long.parseLong("110"));
            book.setBookName("yu");
            book.setPublisher("qq");
            return book;
    
        }
        @GET
        @Path("listbook")
        @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
         @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
        public Listbook  listbook(){
            Book book=new Book();
            book.setBookId(Long.parseLong("110"));
            book.setBookName("yu");
            book.setPublisher("qq");
            Book book2=new Book();
            book2.setBookId(Long.parseLong("112"));
            book2.setBookName("yu2");
            book2.setPublisher("qq2");
            ArrayList<Book> list=new ArrayList<Book>();
            list.add(book);
            list.add(book2);
            Listbook booklist=new Listbook();
            booklist.setListbook(list);
            return booklist;
    
        }
        //网页版本用这个才能接收到参数，正确解析，可以用ajax请求，也可以用浏览器测试工具
        @PUT
    
    
        @Produces(MediaType.APPLICATION_XML)
        public Book newBook(@BeanParam Book book){
            return book;
        }
        //如果用jersey客户端的只能用这个，直接传递实体类和相应实体类
        @PUT
        @Path("Client")
        @Produces(MediaType.APPLICATION_JSON)
        public Book newBook1( Book book){
            return book;
        }
    
    
        //网页版本用这个才能接收到参数，正确解析，可以用ajax请求，也可以用浏览器测试工具
        @POST
        //参数说明 @Consumes 可以接收客户端什么样的形式过来，
        //网页过来的post请求的内容形式一般是application/x-www-form-urlencoded,一般如果不确定注释即可
        //@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
        @Consumes({MediaType.APPLICATION_FORM_URLENCODED})
        //@Produces，返回给客户端的的类型MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON
        //如果请求段没指定就会返回xml优先
        @Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
        public Book  createBook(@BeanParam Book book){
            return book;
        }
        //如果用jersey客户端的只能用这个，直接传递实体类和相应实体类
        //上面和下面代码的区别 @BeanParam Book book，Book book 注意传入的实体类
        @POST
        @Path("Client")
        @Consumes({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
        @Produces(MediaType.APPLICATION_JSON)
        public Book createBook2(Book book) {
            return book;
        }
    
        @DELETE
        public void delete(@QueryParam("bookId") final long bookId){
            System.out.println(bookId);
        }
    }

见注释说明  
可以用ajax来测试，也可以用jersey客户端来测试  
测试端代码如下：

public String getbook() {
            final WebTarget webTarget = client.target(Jaxrs2Client.BASE_URI);
            final WebTarget pathTarget = webTarget.path("BookResourceget");
            final String result = pathTarget.request().get(String.class);
            Jaxrs2Client.LOGGER.debug(pathTarget.getUri());
            Jaxrs2Client.LOGGER.debug(result);
            return result;
        }
        public String delete() {
            final WebTarget webTarget = client.target(Jaxrs2Client.BASE_URI);
            final WebTarget pathTarget = webTarget.path("BookResourceget").queryParam("bookId", "110");
            final Response result = pathTarget.request().delete();
            Jaxrs2Client.LOGGER.debug(pathTarget.getUri());
            Jaxrs2Client.LOGGER.debug(result);
            return result.getStatus() + "";
    
        }
    
        public Book post() {
            final WebTarget webTarget = client.target(Jaxrs2Client.BASE_URI);
            final WebTarget pathTarget = webTarget.path("BookResourceget").path("Client");
            Book book = new Book(100L, "TEST BOOK","你好");
            final Book result = pathTarget.request().post(Entity.entity(book, MediaType.APPLICATION_XML), Book.class);
            Jaxrs2Client.LOGGER.debug(pathTarget.getUri());
            Jaxrs2Client.LOGGER.debug(result);
            return result;
        }
        public Book put() {
            final WebTarget webTarget = client.target(Jaxrs2Client.BASE_URI);
            final WebTarget pathTarget = webTarget.path("BookResourceget").path("Client");
            Book book = new Book(100L, "TEST BOOK","你好2");
            final Book result = pathTarget.request().put(Entity.entity(book, MediaType.APPLICATION_XML), Book.class);
            Jaxrs2Client.LOGGER.debug(pathTarget.getUri());
            Jaxrs2Client.LOGGER.debug(result);
            return result;
        }
