使用CXF创建REST WEBSERVICE

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

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 最后执行

htttp://localhost:8085/reset/services/order/all

返回全部ORDER列表
