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>
