Restful 服务端

1 创建好pojo、dao、service， dao进行数据库操作，service提供服务

@Path("/roomservice")
@Produces("application/xml")
public class RoomService {
    
    @GET
    @Path("/room/{id}")
    @Consumes("application/xml")
    public Room getRoom(@PathParam("id")String id )
    {
        System.out.println("get room by id= "+id);
        Room room=RoomDAO.getRoom(id);
        return room;
    }

    @POST
    @Path("/room")
    @Consumes("application/xml")
    public void addRoom(Room room)
    {
...


通常需要使用注解: GET/POST/PUT/DELETE， Path, Consumes, 有参数的方法需要加上 @PathParam

2 通过JAXRSServerFactoryBean来发布服务 —— 一个类即可！　　

public class Server {

    public static void main(String[] args) {
        RoomService service = new RoomService();

        // Service instance
        JAXRSServerFactoryBean restServer = new JAXRSServerFactoryBean();
        restServer.setResourceClasses(Room.class,Person.class,Room.class);
        restServer.setServiceBean(service);
        restServer.setAddress("http://localhost:9999/");
        restServer.create();
    }
}

restful 客户端

使用一个类即可：org.apache.cxf.jaxrs.client.WebClient ！非常方便

public class Client {
    static WebClient client;

    public static void main(String[] args) {
        client = WebClient.create("http://localhost:9999/");
        put();
    }

    static void get() {
        Room room = client.path("roomservice/room/001")
                .accept("application/xml").get(Room.class);
        System.out.println("get the room which id is:" + room.getId());
    }

    static void post() {
        Room room = new Room();
        room.setId("003");
        client.path("roomservice/room").accept("application/xml")
                .post(room, Room.class);
    }

    static void delete() {
        client.path("roomservice/room/002").accept("application/xml").delete();
    }

    static void put() {
        Room room = new Room();
        room.setId("009");
        client.path("roomservice/room/003").accept("application/xml").put(room);
    }
}
