## 一、环境
1、Eclipse Juno R2
2. Tomcat 7
3. Jersey 2.7 下载地址（ https://jersey.java.net/download.html）
## 二、流程
1.Eclipse 中创建一个 Dynamic Web Project ,本例为“RestDemo”
2.按个各人习惯建好包，本例为“com.waylau.rest.resources”
3.解压jaxrs-ri-2.7，
将api、ext、lib文件夹下的jar包都放到项目的lib下；
项目引入jar包
4.在resources包下建一个class“HelloResource”
~~~
package com.waylau.rest.resources;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.MediaType;
@Path("/hello")
public class HelloResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayHello() {
return "Hello World!" ;
}
@GET
@Path("/{param}")
@Produces("text/plain;charset=UTF-8")
public String sayHelloToUTF8(@PathParam("param") String username) {
return "Hello " + username;
}
}
~~~
5.修改web.xml,添加基于Servlet-的部署
~~~
<servlet>
<servlet-name>Way REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.waylau.rest.resources</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Way REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
~~~
6.项目部署到tomcat,运行
7.浏览器输入要访问的uri地址
[http://localhost:8089/RestDemo/rest/hello](http://localhost:8089/RestDemo/rest/hello)
输出Hello World!
[http://localhost:8089/RestDemo/rest/hello/Way你好吗](http://localhost:8089/RestDemo/rest/hello/Way你好吗)
输出Hello Way你好吗
