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”
参考:https://jersey.java.net/documentation/latest/user-guide.html
2.按个各人习惯建好包,本例为“com.waylau.rest.resources”
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
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
Way REST Service
org.glassfish.jersey.servlet.ServletContainer
jersey.config.server.provider.packages
com.waylau.rest.resources
1
Way REST Service
/rest/*
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
输出Hello World!
