  • Cordova+jQuery Mobile+Spring REST

    Cordova可以方便地建立跨平台的移动应用,使用jQuery Mobile做手机界面,后台使用rest提供数据交互。

    首先,使用jQuery Mobile建立一个页面:

    <!DOCTYPE html>
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css">
    <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
    </head>
    <body>
    
      <script>
            
            $.support.cors =true;
            $.mobile.allowCrossDomainPages=true;
    
            function onSuccess(data, status)
            {
                data = $.trim(data);
                $("#info").text(data);
            }
      
            function onError(data, status)
            {
                // handle an error
            }        
      
            $(document).ready(function() {
                $("#submit").click(function(){
      
                    var formData = $("#callAjaxForm").serialize();
                    
                   $.ajax({
                        type: "POST",
                        url: "http://192.168.1.218:8080/SpringMVC/rest/add",
                        cache: false,
                        data: formData,
                        dataType : 'text',
                        success: onSuccess,
                        error: onError
                    });
    
      
                    return false;
                });
            });
    
        </script>
    
    <div data-role="page">
      <div data-role="header" data-position="fixed">
        <a href="#" data-role="button" data-icon="home">首页</a>
        <h1>欢迎访问我的主页</h1>
        <a href="#" data-role="button" data-icon="search">搜索</a>
      </div>
    
      <div data-role="content">
                <form id="callAjaxForm">
                    <div data-role="fieldcontain">
                        <label for="name">name</label>
                        <input type="text" name="name" id="name" value=""  />
     
                        <label for="age">age</label>
                        <input type="text" name="age" id="age" value=""  />
                        <h3 id="info"></h3>
                        <button data-theme="b" id="submit" type="submit">Submit</button>
                    </div>
                </form>
            </div>
    
      <div data-role="footer" data-position="fixed" >
      <div data-role="navbar" >
      <ul>
           <li><a href="#" data-icon="custom">功能1</a></li>
          <li><a href="#" data-icon="custom">功能2</a></li>
          <li><a href="#" data-icon="custom">功能3</a></li>
          <li><a href="#" data-icon="custom">功能4</a></li>
         </ul>
          </div>
      </div>
    </div>
    
    </body>
    </html>

    后台使用Spring REST:

    package com.garfield.web.springmvc;
    
    import java.io.IOException;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    import net.sf.json.JSONObject;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;
    
    import com.garfield.pojo.User;
    
    @Controller    
    @RequestMapping("/rest") 
    public class HelloWorldControllerAnnotation {
    
        @RequestMapping(value = "/helloworld")
        public ModelAndView helloWorld() {
            ModelAndView mv = new ModelAndView();
            mv.addObject("message", "Hello Garfield !");
            mv.setViewName("hello");
            return mv;
        }
        
        @RequestMapping(value="/get/{id}",method=RequestMethod.GET)
        public String get(@PathVariable String id,HttpServletRequest request ,HttpServletResponse response) throws IOException{
            //request.setAttribute("message", "Hello,This is a example of Spring3 RESTful!<br/>ID:"+id+"");
            //return "index.jsp";
            
            User user=new User();
            user.setName("garfield");
            user.setAge("18");
            
            JSONObject jsonObject = JSONObject.fromObject(user);           
            
            response.getWriter().write(jsonObject.toString());
            return null;
        }
        
        
        @RequestMapping(value="/show",method=RequestMethod.GET)
        public String show(HttpServletRequest request ,HttpServletResponse response) throws IOException{
            response.getWriter().write("show users ....");
            return null;
        }
        
        
        @RequestMapping(value="/edit/{id}",method=RequestMethod.PUT)
        public String edit(@PathVariable String id,HttpServletRequest request ,HttpServletResponse response) throws IOException{
            response.getWriter().write("edit user:"+id);
            return null;
        }
        
        @RequestMapping(value="/remove/{id}",method=RequestMethod.DELETE)
        public String remove(@PathVariable String id,HttpServletRequest request ,HttpServletResponse response) throws IOException{
            response.getWriter().write("delete user:"+id);
            return null;
        }
        
        
        @RequestMapping(value="/add",method=RequestMethod.POST)
        public String add(HttpServletRequest request ,HttpServletResponse response) throws IOException{
            User user = new User();
            user.setName(request.getParameter("name"));
            user.setAge(request.getParameter("age"));
            
            JSONObject jsonObject = JSONObject.fromObject(user);           
            
            response.getWriter().write(jsonObject.toString());
            
            return null;
        }
        
        //多参数传递
        @RequestMapping(value="/test/{id}/{sql}",method=RequestMethod.GET)
        public String test(@PathVariable String id,@PathVariable String sql,HttpServletRequest request ,HttpServletResponse response) throws IOException{
            response.getWriter().write("test,id:"+id+",sql:"+sql);
            return null;
        }
        
    
    }

    然后就可以和后台进行数据交互了。

    注意:

    $.support.cors =true;
    $.mobile.allowCrossDomainPages=true;

    是为了跨域调用。

    运行界面示意:

    附:web.xml配置:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
        id="WebApp_ID" version="3.0">
        <servlet>
            <servlet-name>springmvc</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>

    springmvc-servlet.xml配置:

    <?xml version="1.0" encoding="UTF-8"?> 
    <!--看到下面的beans这个元素标签没有,必须有标签的声明--> 
    <beans xmlns="http://www.springframework.org/schema/beans"

        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
        xsi:schemaLocation="http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context-3.0.xsd
           http://www.springframework.org/schema/tx 
           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
    
        <!-- 扫描定义的bean -->
        <context:component-scan base-package="com.garfield.web.springmvc" />
        
        <!-- 处理器 -->

        <!-- 下面的配置用于非注解 -->

        <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
        <!-- HandlerAdapter -->

        <!-- ViewResolver -->

            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
            <property name="prefix" value="/WEB-INF/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean>
    
    </beans>
