java内嵌jetty服务器

有的时候需要将一个简单的功能封装为服务，相比python使用flask、web.py的简洁，使用java-web显得太重量级，幸好，我们可以直接在java项目中使用jetty来搭建简易服务

 

1、pom.xml加入jetty依赖

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

<dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-server</artifactId> <version>9.4.0.v20161208</version> </dependency>   <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-webapp</artifactId> <version>9.4.0.v20161208</version> </dependency>   <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-continuation</artifactId> <version>9.4.0.v20161208</version> </dependency>   <dependency> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-jsp</artifactId> <version>9.1.4.v20140401</version> </dependency>

　　

2、增加Server

?

1	Serverserver=newServer(12580);

　　

3、设置ServletContextHandler

?

1 2	ServletContextHandlercontext=newServletContextHandler(server,"/"); server.setHandler(context);

　　

4、Context增加Servlet 
4.1 创建Servlet 继承HttpServlet，重载doGet，doPost即可

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

public class XXXHandler extends HttpServlet {       @Override     protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {         JSONObject ret =  new JSONObject();         try {             String ttsTxt = req.getParameter("text");               String outFile = System.nanoTime() + ".mp4";             String url = xx.xxx(ttsTxt,...);             ret.put("ret","0");             ret.put("url",url);         }catch (Exception ex){             ret.put("ret","-1");             ret.put("error",ex.getMessage());         }         if(req.getParameter("callback")!=null) {             resp.getWriter().write(req.getParameter("callback")+"("+ret.toString()+")");         }else {             resp.getWriter().write(ret.toString());         }     }   }

　　

4.2 将Servlet 加入Context

?

1 2	context.addServlet(xxxHandler.class,"/xxx"); context.addServlet(Image2VideoHandler.class,"/*");

　　

5、启动server

?

1 2	server.start(); server.join();

6、在浏览器访问http://localhost:12580/XXX 即可
