用cxf、spring配置restful

一、server端配置：

1.在spring的配置文件中加入：<import resource="RESTful.xml" />

２.RESTful.xml文件内容如下：

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:jaxrs="http://cxf.apache.org/jaxrs"
  xmlns:aop="http://www.springframework.org/schema/springSecurityFilterChainaop"
  xmlns:security="http://www.springframework.org/schema/security"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/aop
   http://www.springframework.org/schema/aop/spring-aop.xsd
   http://www.springframework.org/schema/security
   http://www.springframework.org/schema/security/spring-security-2.0.4.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-servlet.xml" />

 <jaxrs:server id="bookservice" address="/">
  <jaxrs:serviceBeans>
   <ref bean="customerservice" />
  </jaxrs:serviceBeans>
  <jaxrs:providers>
   <bean class="demo.jaxrs.service.SecurityExceptionMapper" />
  </jaxrs:providers>
 </jaxrs:server>

 <bean id="customerservice" class="demo.jaxrs.service.CustomerServiceImpl" />
 <!-- <bean id="customerservice" class="demo.jaxrs.service.CustomerServiceSecuredImpl"/> -->

 <security:global-method-security
  secured-annotations="enabled">
  <security:protect-pointcut
   expression="execution(* demo.jaxrs.service.CustomerService.getCustomer(*))"
   access="ROLE_CUSTOMER, ROLE_ADMIN" />
  <security:protect-pointcut
   expression="execution(* demo.jaxrs.service.CustomerService.addCustomer(*))"
   access="ROLE_ADMIN" />
  <security:protect-pointcut
   expression="execution(* demo.jaxrs.service.CustomerService.updateCustomer(Long,demo.jaxrs.service.Customer))"
   access="ROLE_ADMIN" />
  <security:protect-pointcut
   expression="execution(* demo.jaxrs.service.CustomerService.deleteCustomer(*))"
   access="ROLE_ADMIN" />
  <security:protect-pointcut
   expression="execution(* demo.jaxrs.service.CustomerService.getOrder(*))"
   access="ROLE_CUSTOMER, ROLE_ADMIN" />
 </security:global-method-security>

 <security:http auto-config='true'>
  <security:http-basic />
 </security:http>

 <security:authentication-provider>
  <security:user-service>
   <security:user name="bob" password="bobspassword"
    authorities="ROLE_CUSTOMER" />
   <security:user name="fred" password="fredspassword"
    authorities="ROLE_CUSTOMER, ROLE_ADMIN" />
  </security:user-service>
 </security:authentication-provider>
</beans>

３.CustomerService.java内容如下：

package demo.jaxrs.service;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/customerservice/")
public interface CustomerService {
   
    @GET
    @Path("/customers/{id}/")
    Customer getCustomer(@PathParam("id") String id);

    @PUT
    @Path("/customers/{id}")
    Response updateCustomer(@PathParam("id") Long id, Customer customer);
   
    @POST
    @Path("/customers/")
    Response addCustomer(Customer customer);

    @DELETE
    @Path("/customers/{id}/")
    Response deleteCustomer(@PathParam("id") String id);

    @Path("/orders/{orderId}/")
    Order getOrder(@PathParam("orderId") String orderId);

}
４.CustomerServiceImpl.java内容如下：

package demo.jaxrs.service;

import java.util.HashMap;
import java.util.Map;

import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Response;

public class CustomerServiceImpl implements CustomerService {
    long currentId = 123;
    Map<Long, Customer> customers = new HashMap<Long, Customer>();
    Map<Long, Order> orders = new HashMap<Long, Order>();

    public CustomerServiceImpl() {
        init();
    }

    public Customer getCustomer(String id) {
        System.out.println("----invoking getCustomer, Customer id is: " + id);
        long idNumber = Long.parseLong(id);
        Customer c = customers.get(idNumber);
        return c;
    }

    public Response updateCustomer(Long id, Customer customer) {
        System.out.println("----invoking updateCustomer, Customer name is: " + customer.getName());
        Customer c = customers.get(id);
        if (c == null || c.getId() != customer.getId()) {
            throw new WebApplicationException();
        }
        Response r;
        if (c != null) {
            customers.put(customer.getId(), customer);
            r = Response.ok(customer).build();
        } else {
            r = Response.notModified().build();
        }

        return r;
    }

    public Response addCustomer(Customer customer) {
        System.out.println("----invoking addCustomer, Customer name is: " + customer.getName());
        customer.setId(++currentId);

        customers.put(customer.getId(), customer);

        return Response.ok(customer).build();
    }

    public Response deleteCustomer(String id) {
        System.out.println("----invoking deleteCustomer, Customer id is: " + id);
        long idNumber = Long.parseLong(id);
        Customer c = customers.remove(idNumber);

        Response r;
        if (c != null) {
            r = Response.ok().build();
        } else {
            r = Response.notModified().build();
        }

        return r;
    }

    public Order getOrder(String orderId) {
        System.out.println("----invoking getOrder, Order id is: " + orderId);
        long idNumber = Long.parseLong(orderId);
        Order c = orders.get(idNumber);
        return c;
    }

    final void init() {
        Customer c = new Customer();
        c.setName("John");
        c.setId(123);
        customers.put(c.getId(), c);

        Order o = new Order();
        o.setDescription("order 223");
        o.setId(223);
        orders.put(o.getId(), o);
    }

}
５.server端例子可以参照cxf包中distribution\src\main\release\samples\jax_rs\spring_security的例子。

 

二、client端

１.在spring的配置文件中加入如下内容：<import resource="RESTClient.xml" />

２.RESTClient.xml内容如下：

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://www.springframework.org/schema/beans" xmlns:util="http://www.springframework.org/schema/util"
 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-3.0.xsd">

 <bean id="customerService" class="org.apache.cxf.jaxrs.client.JAXRSClientFactory"
  factory-method="create">
  <constructor-arg type="java.lang.String"
   value="http://192.168.1.101:8080/mvn_struts2/RESTful" />
  <constructor-arg type="java.lang.Class"
   value="demo.jaxrs.service.CustomerService" />
  <constructor-arg type="java.lang.String" value="fred" />
  <constructor-arg type="java.lang.String" value="fredspassword" />
  <constructor-arg type="java.lang.String">
   <null></null>
  </constructor-arg>
 </bean>
</beans>

３.则customerService即可当成spring的bean使用。
