cxf整合spring发布rest服务 httpclient访问服务

1.创建maven web项目并添加依赖

实体类注意添加@XmlRootElement注解

接口添加jaxrs注解,定义数据格式

5.部署至tomcat后打开浏览器采用以下格式访问

url-pattern:web.xml中定义的cxf的servlet拦截目录

address:applicationContext.xml中的<jaxrs:server>标签定义的address

path:在接口中使用@Path注解设定的值

http://ip:port/项目名/url-pattern/address/path/方法路径/参数

6.由于使用浏览器url的方式只能访问注解为@GET的方法,下面给出使用HttpClient访问服务的简单示例

添加以下依赖

 1 <properties>
 2       <httpClient.version>4.5.6</httpClient.version>
 3       <junit.version>4.9</junit.version>
 4   </properties>
 5   <dependencies>
 6     <dependency>
 7         <groupId>org.apache.httpcomponents</groupId>
 8         <artifactId>httpclient</artifactId>
 9         <version>${httpClient.version}</version>
10     </dependency>
11     <dependency>
12         <groupId>junit</groupId>
13         <artifactId>junit</artifactId>
14         <version>${junit.version}</version>
15         <scope>test</scope>
16     </dependency>
17     
18   </dependencies>

 1 package cxf_rest_server.student;
 2 
 3 import org.apache.http.HttpEntity;
 4 import org.apache.http.client.methods.CloseableHttpResponse;
 5 import org.apache.http.client.methods.HttpGet;
 6 import org.apache.http.client.methods.HttpPost;
 7 import org.apache.http.impl.client.CloseableHttpClient;
 8 import org.apache.http.impl.client.HttpClients;
 9 import org.apache.http.util.EntityUtils;
10 import org.junit.Test;
11 
12 /**
13  * 使用httpClient访问服务
14  * @author tele

17 public class StudentClient {
18     @Test
19     public void get() throws Exception{
20         //创建httpclient对象
21         CloseableHttpClient httpClient = HttpClients.createDefault();
22         //创建get对象
23         HttpGet get = new HttpGet("http://127.0.0.1:8080/cxf_rest_spring_server/ss/studentquery/student/queryList/100/123");
24         //执行请求
25         CloseableHttpResponse response = httpClient.execute(get);
26         int statusCode = response.getStatusLine().getStatusCode();
27         if(statusCode == 200){
28             HttpEntity entity = response.getEntity();
29             String result = EntityUtils.toString(entity,"utf-8");
30             System.out.println(result);
31         }
32         response.close();
33         httpClient.close();
34     }
35     
36     @Test
37     public void post() throws Exception {
38         CloseableHttpClient httpClient = HttpClients.createDefault();
39         HttpPost post = new HttpPost("http://127.0.0.1:8080/cxf_rest_spring_server/ss/studentquery/student/query/100");
40         CloseableHttpResponse response = httpClient.execute(post);
41         int statusCode = response.getStatusLine().getStatusCode();
42         if(statusCode == 200) {
43             HttpEntity entity = response.getEntity();
44             String result = EntityUtils.toString(entity,"utf-8");
45             System.out.println(result);
46         }
47         response.close();
48         httpClient.close();
49     }
50 }

7.数据的解析

拿到数据后,根据数据格式进行解析,如果是xml,可以使用jdom,dom4j

如果是json........
