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
