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

<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

Serverserver=newServer(12580);

　　

3、设置ServletContextHandler

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

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

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

　　

5、启动server

server.start();
server.join();

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