使用CXF创建REST WEBSERVICE

简单小结下CXF跟REST搭配webservice的做法,直接举代码为例子:

1 order.java
  package com.example.rest;

import javax.xml.bind.annotation.XmlRootElement;


 这个order可以在service中使用就代表当前的类，然后就是简单地调用关系，相当于操作的是json和xml格式的数据，返回的是把这个值当做，相应的json或者xml格式输出输出

@XmlRootElement(name = "Order")//
public class Order {

    private int orderId;
    private String itemName;
    private int quantity;
    private String customerName;
    private String shippingAddress;

    public int getorderId() {
        return orderId;
    }
    public void setorderId(int orderId) {
        this.orderId = orderId;
    }
    public String getItemName() {
        return itemName;
    }
    public void setItemName(String itemName) {
        this.itemName = itemName;
    }
    public int getQuantity() {
        return quantity;
    }
    public void setQuantity(int quantity) {
        this.quantity = quantity;
    }
    public String getCustomerName() {
        return customerName;
    }
    public void setCustomerName(String customerName) {
        this.customerName = customerName;
    }
    public String getShippingAddress() {
        return shippingAddress;
    }
    public void setShippingAddress(String shippingAddress) {
        this.shippingAddress = shippingAddress;
    }

}

2 orderlist.java
   package com.example.rest;

import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "OrderList") //xml文件的根节点 public class OrderList {     @XmlElement(name = "order",required = true)     List <Order> orders;     public List<Order> getorder() {         if (orders == null) {             orders = new ArrayList<Order>();         }         return this.orders;     } } 3 orderinof.java的接口    package com.example.rest; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; @Path("/Order/") public interface OrderInfo { @GET @Produces ("application/xml") @Path("{orderId}") public Order getorder(@PathParam ("orderId") int officeId); @GET @Produces ("application/xml") @Path ("All") public OrderList getAllOrders(); } 4 OrderinfoImpl.java接口实现类    package com.example.rest; import java.util.ArrayList; import java.util.List; public class OrderInfoImpl implements OrderInfo {     List <Order> list = new ArrayList<Order>();     OrderInfoImpl(){         Order order = new Order();         order.setorderId(1);         order.setItemName("Soap");         order.setQuantity(120);         order.setCustomerName("Sandeep");         order.setShippingAddress("Gurgaon");         list.add(0,order);         order.setorderId(2);         order.setItemName("Shampoo");         order.setQuantity(50);         order.setCustomerName("Sandeep");         order.setShippingAddress("Gurgaon");         list.add(1,order);     }     @Override     public Order getorder(int orderId) {         System.out.println("Inside the Getorder...");         if (list.get(0).getorderId() == orderId) {             return list.get(0);         } else if (list.get(1).getorderId() == orderId) {             return list.get(1);         } else {             return null;         }     }     @Override     public OrderList getAllOrders() {         OrderList details = new OrderList();         for(Order order : list) {             details.getorder().add(order);         }         return details;     } } CXF的配置    <beans xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemalocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">   <import resource="classpath:meta-inf/cxf/cxf.xml">   <import resource="classpath:meta-inf/cxf/cxf-extension-jaxrs-binding.xml">   <import resource="classpath:meta-inf/cxf/cxf-servlet.xml">   <jaxrs:server address="/" id="connectionService">    <jaxrs:servicebeans>               <ref bean="order">    </ref></jaxrs:servicebeans>    <jaxrs:extensionmappings>     <entry key="xml" value="application/xml">    </entry> </jaxrs:extensionmappings>   </jaxrs:server> <bean class="com.javatch.rest.OrderImpl" id="order"> </bean> </import> </import> </import> </beans> web.xml的配置记得加上CXF配置   <?xml version="1.0"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems,Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>   <display-name>RestWithCXF</display-name>   <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:com/javatch/rest/cxf.xml</param-value>   </context-param>   <listener>    <listener-class>     org.springframework.web.context.ContextLoaderListener    </listener-class>   </listener>   <servlet>    <servlet-name>CXFServlet</servlet-name>    <servlet-class>     org.apache.cxf.transport.servlet.CXFServlet    </servlet-class>   </servlet>   <servlet-mapping>    <servlet-name>CXFServlet</servlet-name>    <url-pattern>/services/*</url-pattern>   </servlet-mapping> </web-app> 5 最后运行   htttp://localhost:8085/reset/services/order/all 返回所有ORDER列表
