Spring RPC 入门学习（3）-获取Student对象

Spring RPC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);

}

2.新建RPC接口的实现类，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;
    }

}

3. 配置Spring和RPC，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.Sping的配置文件：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：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. 编写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 ceshi(){
        var name = document.getElementById("name").value;
        rpc.call('getStudentById',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>
