关于jersey传实体类作为参数，及接收回来是自定义对象的代码说明

jersey接收自定义对象参数，和返回自定义对象代码示例  
基础代码就不说了，服务端代码如下：

@PUT
        @Path("Client")
        @Produces(MediaType.APPLICATION_JSON)
        public Book newBook1( Book book){
            return book;
        }

客户端调用代码如下：

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;
        }

代码分析如下：

发送的是Book这个对象过去，再接收回来Book对象回来
        Book book = new Book(100L, "TEST BOOK","你好2");
        final Book result = pathTarget.request().put(Entity.entity(book, MediaType.APPLICATION_XML), Book.class);

发送复合型和接收复合型的对象代码如下：  
服务代码：

@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;
    
        }

客户端调用代码如下：

public Listbook getlist() {
            final WebTarget webTarget = client.target(Jaxrs2Client.BASE_URI);
            final WebTarget pathTarget = webTarget.path("BookResourceget").path("listbook");
            final Listbook result =pathTarget.request().get(Listbook.class);
            Jaxrs2Client.LOGGER.debug(pathTarget.getUri());
            Jaxrs2Client.LOGGER.debug(result);
            return result;
        }

附Listbook对象代码：

package com.example.client.entity;
    
    import java.util.List;
    
    import com.example.domain.Book;
    
    public class Listbook { 
      List<Book> listbook;
    
    public List<Book> getListbook() {
        return listbook;
    }
    
    public void setListbook(List<Book> listbook) {
        this.listbook = listbook;
    }
    }
