Jersey+Spring+Maven（转）

spring和maven的搭建参考相关文档。本文只介绍与jersey有关配置。

一、jersey在maven中的依赖包

• <!-- jersey -->

  <dependency>
  

  <groupId>com.sun.jersey</groupId>
      <artifactId>jersey-core</artifactId>
      <version>1.8</version>

  </dependency>

  <dependency> 
  

  <groupId>com.sun.jersey</groupId>
      <artifactId>jersey-server</artifactId>
      <version>1.8</version>

  </dependency>

  <dependency> 
  

  <groupId>com.sun.jersey</groupId>
      <artifactId>jersey-client</artifactId>
      <version>1.8</version>

  </dependency>

  <dependency> 
  

  <groupId>javax.ws.rs</groupId>
       <artifactId>javax.ws.rs-api</artifactId>
       <version>2.0-m10</version>

  </dependency>

  <dependency> 
  

  <groupId>javax.ws.rs</groupId>
      <artifactId>jsr311-api</artifactId>
      <version>1.1.1</version>

  </dependency>

  <dependency> 
  

  <groupId>asm</groupId>
      <artifactId>asm</artifactId>
      <version>3.3.1</version>

  </dependency>

  <!-- jersey end -->

需要json，加入以下

<!--  json-->

<dependency>

<groupId>com.sun.jersey</groupId>

<artifactId>jersey-json</artifactId>

<version>1.8</version>

</dependency>

<dependency>

<groupId>org.codehaus.jackson</groupId>

<artifactId>jackson-mapper-asl</artifactId>

<version>1.8.8</version>

</dependency>

<!--  json-->

尽量保持包版本的一致

二、整合spring

1、 引入整合包，注意版本

<!-- jersey spring -->

<dependency>

<groupId>com.sun.jersey.contribs</groupId>

<artifactId>jersey-spring</artifactId>

<version>1.8</version>

<!-- 去除自带的spring版本 -->

<exclusions>

<exclusion>

<groupId>org.springframework</groupId>

<artifactId>spring-aop</artifactId>

</exclusion>

<exclusion>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

</exclusion>

<exclusion>

<groupId>org.springframework</groupId>

<artifactId>spring-beans</artifactId>

</exclusion>

<exclusion>

<groupId>org.springframework</groupId>

<artifactId>spring-core</artifactId>

</exclusion>

<exclusion>

<artifactId>spring-web</artifactId>

<groupId>org.springframework</groupId>

</exclusion>

</exclusions>

</dependency>

<!-- jersey spring end-->

   2、web.xml配置

所有rest请求都经过spring过滤

<!-- jersey spring -->
<dependency>
  <groupId>com.sun.jersey.contribs</groupId>
  <artifactId>jersey-spring</artifactId>
  <version>1.8</version>
  <!-- 去除自带的spring版本 -->
  <exclusions>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-aop</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
    </exclusion>
    <exclusion>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
    </exclusion>
    <exclusion>
      <artifactId>spring-web</artifactId>
      <groupId>org.springframework</groupId>
    </exclusion>
  </exclusions>
</dependency>
<!-- jersey spring end-->
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>3.8.1</version>
  <scope>test</scope>
</dependency>

三、编写服务端资源

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement

public class User  implements java.io.Serializable{

private static final long serialVersionUID = 1L;  

private String userName = "";  

private int age = 0;  

public String getUserName() {  

return userName;  

}  

public void setUserName(String userName) {  

this.userName = userName;  

}  

public int getAge() {  

return age;  

}  

public void setAge(int age) {  

this.age = age;  

}

public String toString() {

return "name:"+ userName + " age:" + age;

}

}

import javax.ws.rs.FormParam;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement //表示可以被转换为xml或json格式

public class Home   implements java.io.Serializable {

@FormParam("roomno")

private int roomNo;

@FormParam("address")

private String address;

private String longtime;

public int getRoomNo() {

return roomNo;

}

public void setRoomNo(int roomNo) {

this.roomNo = roomNo;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public String getLongtime() {

return longtime;

}

public void setLongtime(String longtime) {

this.longtime = longtime;

}

public String toString() {

return "roomNo:" + roomNo + "  address:" + address + "  longtime:" + longtime;

}

}

2、编写资源接口

import javax.ws.rs.BeanParam;

import javax.ws.rs.Consumes;

import javax.ws.rs.FormParam;

import javax.ws.rs.GET;

import javax.ws.rs.POST;

import javax.ws.rs.Path;

import javax.ws.rs.PathParam;

import javax.ws.rs.Produces;

import javax.ws.rs.QueryParam;

import javax.ws.rs.core.MediaType;

@Component         //定义此类为spring组件,即bean类.

@Scope("prototype")   //Spring会针对每一个request请求都生成新的Jersey服务类实例，此方法不需要配置Spring RequsetContextListener

@Path("/restresource")

public class TestRestResource {

1、无参数返回json格式，如返回xml，将Produces参数修改为MediaType.APPLICATION_XML

@GET

@Path("/getUser")

@Produces(MediaType.APPLICATION_JSON)

public User getUser() {  

User user = new User();  

user.setUserName("sed");  

user.setAge(29);  

return user;  

}

2、@PathParam("id")获取URI中指定规则的参数

@GET

@Path("getUser/{id}")

@Produces(MediaType.TEXT_PLAIN)

public String getUserId(@PathParam("id") String id) {

return id; 

}

3、@QueryParam 用于获取GET请求中的查询参数

@GET  

@Path("getId")  

@Produces(MediaType.TEXT_PLAIN)  

public String getId(@QueryParam("id") String id)  

{  

return id;  

}

4、输入参数为xml格式，输出为json格式。可以根据需要切换produces和consumes的类型

@POST

@Path("insertUser")

@Produces(MediaType.APPLICATION_JSON)  //指定发送请求的 MIME 类型

@Consumes(MediaType.APPLICATION_XML)  //指定响应所能接受的 MIME 类型

public User insertuser(User user) {

return user; 

}

5、BeanParam 当请求参数很多时，比如客户端提交一个修改用户的PUT请求，请求中包含很多项用户信息

@PUT

@Path("insertUserFromBean")

@Consumes(MediaType.APPLICATION_JSON)

@Produces(MediaType.APPLICATION_JSON)

public User inserthome(@BeanParam User user) {

return user;

}

6、@FormParam 从POST请求的表单参数中获取数据

@POST

@Path("insertUserFromForm")

@Consumes("application/x-www-form-urlencoded")

@Produces(MediaType.TEXT_PLAIN)  

public String insertuser(@FormParam("username") String userName, @FormParam("age") int age) {

User user = new User();

user.setUserName(userName);

user.setAge(age);

return user.toString();

}

7、多参数传递

@POST

@Path("map")

@Produces(MediaType.TEXT_PLAIN)

public String getMap(MultivaluedMap<String, String>  formParams) {

String result = "who:" + formParams.getFirst("who") + " ; what:"+formParams.getFirst("what");

return formParams.toString();

}

8、

@DELETE

@Path("deleteUser/{id}")

@Produces(MediaType.TEXT_PLAIN)

public String deleteUser(@PathParam("id") String id) {

//System.out.println(uriInfo.getAbsolutePath().toString());

return "delete " + id;

}

}

四、客户端调用

private static WebResource getWr(String USER_URL)  {

Client c = Client.create();  //创建一个 com.sun.jersey .api.client.Client 类的实例

WebResource wr = c.resource(USER_URL);  // 建了一个 WebResponse 对象

return wr;

}

1、调用getUser

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/getUser";

System.out.println(getWr(USER_URL).get(String.class));

输出：

{"userName":"sed","age":29}

2、调用getUser/{id}

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/getUser";

String result = getWr(USER_URL).path("hnsed").get(String.class) ;

System.out.println(result);

输出：

hnsed

3、调用getId

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/getId";

String result = getWr(USER_URL).queryParam("id", "109").get(String.class);

System.out.println(result);

输出：

109

4、调用insertUser

代码：

User user = new User();

user.setUserName("hndes");

user.setAge(39);

String USER_URL = "http://localhost:8000/restful/services/restresource/insertUser";

MultivaluedMapImpl params = new MultivaluedMapImpl();

params.add("user", user);

String result = getWr(USER_URL).entity(user,MediaType.APPLICATION_XML).post(String.class);

System.out.println(result);

输出：

{"userName":"hndes","age":39}

5、调用insertUserFromBean

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/insertUserFromBean";

String json = "{\"userName\":\"szh\",\"age\":\"6\"}";

System.out.println(getWr(USER_URL).entity(json,MediaType.APPLICATION_JSON).put(String.class));

输出：

{"userName":"szh","age":6}

6、调用insertUserFromForm

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/insertUserFromForm";

Form form = new Form();

form.add("username", "sed");

form.add("age",39);

//ClientResponse 对象代表了一个客户端收到的 HTTP 响应。

ClientResponse response = getWr(USER_URL).type(MediaType.APPLICATION_FORM_URLENCODED).post(ClientResponse.class, form);

int status = response.getStatus();   //获取对应请求的 HTTP 状态码

System.out.println(response.getEntity(String.class));

输出：

name:sed age:39

7、调用map

代码：

MultivaluedMap<String, String> params = new MultivaluedMapImpl();

params.add("who", "sed");

params.add("what","dohousework");

params.add("how","good");

params.add("where","hk");

params.add("when","long time");

String USER_URL = "http://localhost:8000/restful/services/restresource/map";

String result = getWr(USER_URL).post(String.class,params);

System.out.println(result);

输出：

{what=[dohousework], how=[good], when=[long time], where=[hk], who=[sed]}

8、调用deleteUser

代码：

String USER_URL = "http://localhost:8000/restful/services/restresource/deleteUser";

String result = getWr(USER_URL).path("109").delete(String.class);

System.out.println(result);

输出：

delete 109

注：1、Client 类是创建一个 RESTful Web Service 客户端的主要配置点。你可以使用它来配置不同的客户端属性和功能，并且指出使用哪个资源提供者。创建一个 Client 类的实例是一个比较昂贵的操作，所以尽量避免创建一些不需要的客户端实例。比较好的方式是尽可能地复用已经存在的实例。

2、通过使用 WebResource 对象来创建要发送到 Web 资源的请求，以及处理从 Web 资源返回的响应。例如，你可以使用 WebResource 对象来发送 HTTP GET、PUT、POST 以及 DELETE 请求
