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> </html>
