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
