Spring搭建RPC环境
第一,下载所需要的jar包,下载地址:https://yunpan.cn/cPErQeANrSMyB (提取码:63e5),见下图:
第二,新建动态WebProject,把所下载的jar包,放入lib目录下;
第三,新建远程调用接口;
package com.cvicse.ump.rpc; public interface HelloWorld { public String sayHello(String name); }
第四,添加接口的实现;
package com.cvicse.ump.rpc.imp; import com.cvicse.ump.rpc.HelloWorld; public class HelloWorldImp implements HelloWorld { @Override public String sayHello(String name) { return "hello,"+name; } }
第五,配置Spring和RPC,修改web.xml文件,内容如下:
<?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>
第六,新建Spring和rpc的配置文件,applicationContext.xml和spring-service.xml
applicationContext.xml内容如下:
<?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>
spring-service.xml内容如下:
<?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="helloWorldImp" class="com.cvicse.ump.rpc.imp.HelloWorldImp" /> <bean id="/HelloWorld" class="com.googlecode.jsonrpc4j.spring.JsonServiceExporter"> <property name="service" ref="helloWorldImp" /> <property name="serviceInterface" value="com.cvicse.ump.rpc.HelloWorld" /> </bean> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" /> </beans>
第七步,添加rpc相关的js文件:jsonrpcjs-0.1.8.min.js,下载地址:https://yunpan.cn/cPExdMGxm2kuK (提取码:bdf2)
在WebContent目录下,新建js文件夹,把jsonrpcjs-0.1.8.min.js放到该文件夹下
第八步,编写前台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/jquery-1.11.1.min.js"></script> <script src="js/jsonrpcjs-0.1.8.min.js"></script> <script type="text/javascript"> var rpc = new jsonrpc.JsonRpc("rpcService/HelloWorld"); function ceshi(){ var name = document.getElementById("name").value; rpc.call(‘sayHello‘,name, { success : function(r) { alert(r); }, failure : function(reason) { alert("false"); }, }); } </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>
运行结果如下图所示:
