Spring RPC 入门学习（2）-获取Map对象

Spring RPC传递Map用例编写

1. 新建RPC接口类

package com.cvicse.ump.rpc.interfaceDefine;

import java.util.Map;

public interface MapTest {

    public Map getByName(String name);

}

2.RPC接口实现类

package com.cvicse.ump.rpc.interfaceImp;

import java.util.HashMap;

import java.util.Map;

import com.cvicse.ump.rpc.interfaceDefine.MapTest;

public class MapTestImp implements MapTest{

    @Override

    public Map getByName(String name) {

        HashMap <String,String>retMap = new HashMap<String, String>();

        retMap.put("name", name);

        retMap.put("id", name+"_001");

        retMap.put("age", name+"_25");

        retMap.put("birthday", name+"_19880923");

        retMap.put("address", name+"_山东济南");

        return retMap;

    }

}

3. 搭建RPC和SPRING配置文件，web.xml文件配置如下：

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 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">

  <display-name>SpringRPC</display-name>

  <!-- Spring相关配置 -->

  <context-param>

      <param-name>contextConfigLocation</param-name>

      <param-value>/WEB-INF/applicationContext.xml</param-value>

  </context-param>

  <listener>

      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <!-- RPC Servlet相关配置 -->

  <servlet>

      <servlet-name>rpcServlet</servlet-name>

      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

      <init-param>

          <param-name>contextConfigLocation</param-name>

          <param-value>/WEB-INF/spring-service.xml</param-value>

      </init-param>

      <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

      <servlet-name>rpcServlet</servlet-name>

      <url-pattern>/rpcService/*</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>

4. RPC配置：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">

    <description>Spring Service Configuration</description>

    <bean id="mapTest" class="com.cvicse.ump.rpc.interfaceImp.MapTestImp" />

    <bean id="/MapTestImp" class="com.googlecode.jsonrpc4j.spring.JsonServiceExporter">

        <property name="service" ref="mapTest" />

        <property name="serviceInterface" value="com.cvicse.ump.rpc.interfaceDefine.MapTest" />

    </bean> 

    <bean

        class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

</beans>

5.Spring配置

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

 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">

    <description>Spring Context Configuration</description>

</beans>

6.引入相应的jar和js文件；

7.编写jsp文件：

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Spring RPC TEST</title>

    <script src="js/jsonrpcjs-0.1.8.min.js"></script>

    <script type="text/javascript">

        var rpc = new jsonrpc.JsonRpc("rpcService/MapTestImp");

function ceshi(){

    var name = document.getElementById("name").value;

    rpc.call('getByName',name, {

        success : callback,

        failure : errorcallback,

    });

    function callback(r){

        var name=r.name;

        var age = r.age;

        alert(age);

    }

    function errorcallback(r){

        alert(r);

    }

}

    </script>

</head>

<body>

<h1>Spring RPC 测试</h1>

请输入姓名：<input type="text" id="name" size="17">

<input type="button" value="Hello" id="but1" onclick="ceshi()">

</body>

</html>

如果不引入rpc的js文件，只用jquery的ajax实现，代码如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Spring RPC TEST</title>

    <script src="js/jquery-1.11.1.min.js"></script>

    <script type="text/javascript">

var url = "http://localhost:8080/SpringRpc2/rpcService/MapTestImp";

$(document).ready(

        function(){

            $("#but2").click(//添加点击事件

                    function(){

                        var name = $("#name").val();//获取文本框输入的内容

                        //p必须按照以下格式，id代表一次请求；method代表要调用的函数；params代表函数的参数

                        var p = {

                                "id" : 3,

                                "method" : "getByName",

                                //"params" : [ {"id":12,"name":"aaa"} ]

                                "params" : [ name ]

                            };

                        $.ajax( {

                            type : "post",

                            url : url,

                            dataType : "json",

                            data : JSON.stringify(p),//转JSON

                            contentType : "application/json; charset=UTF-8",

                            success : function(msg) {

                                var retValue = msg.result;

                                alert("Data Saved: "+retValue.address );

                            },

                            error:function(error){

                                alert("查询失败");

                            }

                        });

                    }

                    );

        }

        );    

    </script>

</head>

<body>

<h1>Spring RPC 测试</h1>

请输入姓名：<input type="text" id="name" size="17">

<input type="button" value="测试2" id="but2">

</body>
