Spring RPC 入门学习（3）-插入Student对象

时间：2021-11-21 05:46:53

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>
