<Reslet1>：Reslet和Spring配置简单web访问_JAVA_编程开发_程序员俱乐部

Restlet针对每个uri指定一个资源。使用spring注解，代码已经跑通，附件项目下载，欢迎留言讨论
注意：web.xml配置component,

class="java">
<init-param>
      <param-name>org.restlet.component</param-name>
      <param-value>component</param-value>
</init-param>

param-value要和applicationContext.xml中bean的id保持椅一致
基本模拟结构如图：

下面上代码：
CustomerDAO

 public interface CustomerDAO {  
    public String getCustomerById(String id);  
}  

OrderDao

public interface OrderDao {
	 public abstract String getOrderId(String id);
}

CustomerDAOImpl

@Service
@Scope("prototype")
public class CustomerDAOImpl implements CustomerDAO {
	public String getCustomerById(String id) {
		return "The customer id is " +id;
	}
}

OrderDaoImpl

@Service
@Scope("prototype")
public class OrderDaoImpl implements OrderDao {

	@Override
	public String getOrderId(String id) {
		return "this order id is "+id;
	}
}

CustomerResource

@Controller
@Scope("prototype")
public class CustomerResource extends ServerResource {  
	
	public CustomerResource() {
		// TODO Auto-generated constructor stub
	}
    String customerId = "";  
  
    @Get  
    public Representation getRepresentation() {  
    	customerId = (String) getRequest().getAttributes().get("custId");  
    	String string = customerDAO.getCustomerById(customerId);
    	return new StringRepresentation(string);  
    }  
    
    @Autowired
    private CustomerDAO customerDAO;
 
}  

OrderResource

@Controller
public class OrderResource extends ServerResource{
	    String orderId = "";  

	    @Get  
	    public Representation getRepresentation() {  
	    	orderId = (String) getRequest().getAttributes().get("orderId");  
	    	return new StringRepresentation(orderDao.getOrderId(orderId));  
	    }  
	    
	    @Autowired
	    private OrderDao orderDao;
}

配置好启动tomcat浏览器输入：
http://localhost:8080/test-restlet/order/1
页面显示：
this order id is 1

http://localhost:8080/test-restlet/customer/1
页面显示：
The customer id is 1
