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;


@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")
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
