Spring RPC 向后台传递对象
1. 新建RPC接口：StudentInterface.java
package com.cvicse.ump.rpc.interfaceDefine; import com.cvicse.ump.student.Student; public interface StudentInterface { public Student getStudentById(String id); public Boolean insertStudent(Student student); }
2. 新建RPC接口实现类:StudentManager.java
package com.cvicse.ump.rpc.interfaceImp; import com.cvicse.ump.rpc.interfaceDefine.StudentInterface; import com.cvicse.ump.student.Student; public class StudentManager implements StudentInterface { @Override public Student getStudentById(String id) { Student student = new Student(); student.setId(id); student.setName("xiaoDy"); student.setAge(23); student.setAddress("河北石家庄"); return student; } @Override public Boolean insertStudent(Student student) { System.out.println(student); return true; } }
3. 配置Spring和RPC服务，修改web.xml
<?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. Spring配置文件：applicationContext.xml
<?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>
5. rpc 配置文件:spring-service.xml
<?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="/studentService" class="com.googlecode.jsonrpc4j.spring.JsonServiceExporter"> <property name="service"> <bean class="com.cvicse.ump.rpc.interfaceImp.StudentManager"></bean> </property> <property name="serviceInterface" value="com.cvicse.ump.rpc.interfaceDefine.StudentInterface" /> </bean> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" /> </beans>
6. 引入js文件和需要的jar包
7.新建jsp文件：index.jsp
<%@ 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/studentService"); function selectStudent(){ var name = document.getElementById("num").value; rpc.call(‘getStudentById‘,name, { success : callback, failure : errorcallback, }); } function callback(r){ var id=r.id; var name=r.name; var age = r.age; var address = r.address; document.getElementById("id").value = id; document.getElementById("name").value = name; document.getElementById("age").value = age; document.getElementById("address").value = address; } function errorcallback(r){ alert(r); } function insertStudent(){ var id=document.getElementById("id").value; var name=document.getElementById("name").value; var age = document.getElementById("age").value; var address = document.getElementById("address").value; var student = {"id" : id, "name" : name, "age" : age, "address" : address}; rpc.call(‘insertStudent‘,student, { success : insertCallBack, failure : errorcallback, }); } function insertCallBack(r){ if(r==true){ alert("插入成功"); }else{ alert("插入失败"); } } </script> </head> <body> <h1>Spring RPC 测试</h1> 学号：<input type="text" id="id" size="17"><br> 姓名：<input type="text" id="name" size="17"><br> 年龄：<input type="text" id="age" size="17"><br> 地址：<input type="text" id="address" size="17"><br> <br> <input type="button" value="插入" onclick="insertStudent()"> <br><br> 查询学号：<input type="text" id="num" size="17"><br> <input type="button" value="查询" onclick="selectStudent()"> </body> </html>
