基于cxf开发restful风格的Web Service

一、写在前面

　　webservice一些简单的其他用法和概念，就不在这里赘述了，相信大家都可以在网上查到，我也是一个新手，写这篇文章的目的一方面是想记录自己成长的历程，另一方面是因为学习这个的时候花了点时间，希望本文章能为大家节约点时间。当然描述的可能不到位，望谅解。

二、创建项目

2.1、创建公用接口project

　　为了方便服务端和客户端调用接口可以先创建一个接口java project，单独建一个接口project的用处后面再说。

然后导入对应jar包，可以去cxf官网下载http://cxf.apache.org/download.html把里面的所有包可以都导入

新建一个实体类User

定义实体类

package com.test.entity;
import javax.xml.bind.annotation.XmlAccessType;

import javax.xml.bind.annotation.XmlAccessorType;

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement

@XmlAccessorType(XmlAccessType.FIELD)

public class User {

private String name;

private String sex;

private Integer age;
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> User(){
    
}
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String getName() {
    </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> name;
}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> setName(String name) {
    </span><span style="color: #0000ff;">this</span>.name =<span style="color: #000000;"> name;
}
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String getSex() {
    </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> sex;
}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> setSex(String sex) {
    </span><span style="color: #0000ff;">this</span>.sex =<span style="color: #000000;"> sex;
}
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> Integer getAge() {
    </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> age;
}
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> setAge(Integer age) {
    </span><span style="color: #0000ff;">this</span>.age =<span style="color: #000000;"> age;
}
@Override
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String toString() {
    </span><span style="color: #0000ff;">return</span> "User [name=" + name + ", sex=" + sex + ", age=" + age + "]"<span style="color: #000000;">;
}

}

新建对应接口和继承接口

对应代码

package com.test.interfaces;
import javax.ws.rs.POST;

import javax.ws.rs.Path;
import com.test.entity.User;
@Path(value="/user")

public interface IuserFacade extends CommonFacade{

public final static String FACADE_NAME = "testFacade";
        @POST
        @Path(value</span>="/getString"<span style="color: #000000;">)
        </span><span style="color: #0000ff;">public</span> String getString() <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception;
        
        @POST
        @Path(value</span>="/getUserName"<span style="color: #000000;">)
        </span><span style="color: #0000ff;">public</span> User getUser() <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception;
        

}</span></pre>

package com.test.interfaces;
import javax.ws.rs.Consumes;

import javax.ws.rs.Produces;
@Consumes(value = { CommonFacade.APPLICATION_JSON_UTF_8, CommonFacade.APPLICATION_XML_UTF_8 })

@Produces(value = { CommonFacade.APPLICATION_JSON_UTF_8, CommonFacade.APPLICATION_XML_UTF_8 })

public interface CommonFacade {
</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">final</span> <span style="color: #0000ff;">static</span> String APPLICATION_JSON_UTF_8 = "application/json; charset=UTF-8"<span style="color: #000000;">;

</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">final</span> <span style="color: #0000ff;">static</span> String APPLICATION_XML_UTF_8 = "application/xml; charset=UTF-8"<span style="color: #000000;">;

}

接口定义完成，下面创建web service。

2.2、创建实现接口web service

　　这里创建的普通的web project，实现web service主要是看配置文件。

因为这里的需要实现上面建的接口，所以先关联Test-interfacse

这样在实现的时候才可以用不然会提示不存在

实现类为

package com.test.interfacesImpl;
import org.springframework.stereotype.Service;
import com.test.entity.User;

import com.test.interfaces.IuserFacade;
@Service(value = IuserFacade.FACADE_NAME)

public class IuserFacadeImpl implements IuserFacade{
@Override
</span><span style="color: #0000ff;">public</span> String getString() <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception {
    
    </span><span style="color: #0000ff;">return</span> "this is ws test"<span style="color: #000000;">;
}

@Override
</span><span style="color: #0000ff;">public</span> User getUser() <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception {
    User user</span>=<span style="color: #0000ff;">new</span><span style="color: #000000;"> User();
    user.setAge(</span>13<span style="color: #000000;">);
    user.setName(</span>"minzhou"<span style="color: #000000;">);
    user.setSex(</span>"man"<span style="color: #000000;">);
    </span><span style="color: #0000ff;">return</span><span style="color: #000000;"> user;

}

}

创建conf ，在conf里面创建对应xml

对应applicationContext-cxf.xml和applicationContext-default.xml分别为

运行后输入http://localhost:8080/Test-WS/rs/?_wadl得到

这里web service端就完成了，通过把地址发给别人就可以访问了，这里面的接口project就可以同时打包发过去，调用的时候就可以引用接口jar包，和地址，访问了。

当然到这里还存在问题，在客户端调用的时候就会发现问题，有兴趣的可以先把这放着，直接写客户端代码，然后调用，看看是什么问题。为了避免问题我先把代码加上

新加一个类

package com.test.interfacesImpl;
import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider;
public class ISSJacksonJaxbJsonProvider extends JacksonJaxbJsonProvider {

public ISSJacksonJaxbJsonProvider(ObjectMapper objectMapper){

super(objectMapper, DEFAULT_ANNOTATIONS);

}

}

修改applicationContext-cxf.xml 增加<jaxrs:providers></jaxrs:providers>引用新建的类

<span style="color: #0000ff;">&lt;/</span><span style="color: #800000;">jaxrs:server</span><span style="color: #0000ff;">&gt;</span>

</beans>

三、客户端实现web service

　　创建一个web project Test-Client同理关联接口，当然也可以不关联接口，直接把接口所导成的jar包导入即可。因为是本地项目所以可以这样，若是给人调用，只需要把web service接口地址和打包的接口jar给人就可以。

创建调用外部webservice控制器

testcontroller.java代码

package com.test.conroller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;
import com.test.entity.User;

import com.test.interfaces.IuserFacade;
@Controller

@RequestMapping("/test")

public class TestController {

@Resource(name =  "testfacade")

private IuserFacade testfacae;
@RequestMapping("/getString")
public @ResponseBody
void testGetString()throws Exception {
    String tests=testfacae.getString();
    System.out.println(tests);
}

@RequestMapping("/getUser")
public  @ResponseBody
String testGetUser()throws Exception{
    
    User users=testfacae.getUser();
    System.out.println(users.toString());
    
    System.out.println("my name is:"+users.getName()+" and my age is "+users.getAge());
    return users.toString();
    
/*    UserQueryResp uq=userFacade.getUserQueryRespById("40289518501706fe01504a91cc2c00d8");*/
    

    
}

}

这里@Resource(name = "testfacade")需要在xml中配置

具体applicationContext-cxf.xml代码

这样启动项目后可以访问http://localhost:8080/Test-Client/dispatcher/test/getUser得到，这样通过客户端访问服务端就可以得到相应的值，这里面的值比较简单，若是webservice端链接上数据库，就可以取得对应数据，客户端也可以在对应页面上获取值，本文只是写对应过程。当然里面的配置文件可能会有多余的，但是大致思想是这样的。

总结：1、通过创建web service 暴露对应访问地址，可以让开发人员调用而保护数据。

　　　2、单独创建接口project可以避免在服务端和客户端同时编辑接口，而且给外部访问的时候可以通过导入jar包提供方便

　　　3、对应代码下载http://files.cnblogs.com/files/minzhousblogs/TestWebServise001.zip 里面没有jar包，可以直接放jar
