SpringHttpInvoker解析1-使用示例

服务端

定义服务接口UserService

import java.util.List;
import com.gosun.jws.daomain.Users;
public interface UserService {
public List<Users> geAlltUsers();
public Users getUser(String id);
public void save(Users user);
public void saves(List<Users> users);
}

服务接口实现类

import java.util.List;
import com.gosun.jws.daomain.Users;
import com.gosun.jws.daomain.UsersFactory;
public class UserServiceImpl implements UserService {
@Override
public List<Users> geAlltUsers() {
return UsersFactory.getUsers();
}
@Override
public Users getUser(String id) {
System.out.println(id);
return UsersFactory.getUser();
}
@Override
public void save(Users user) {
System.out.println(user.toJson());
}
@Override
public void saves(List<Users> users) {
for (Users u : users) {
System.out.println(u.toJson());
}
}
}

配置Spring的HttpInvokerServiceExporter和SimpleUrlHandlerMapping

<!-- 在Spring的httpInvoker服务 -->
<bean id="httpInvokerUserService"
class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
<!--需要发布的实现类 -->
<property name="service" ref="userServiceHttpInvoker" />
<property name="serviceInterface" value="com.gosun.jws.httpinvoker.UserService" />
</bean>
<!-- 将特定的请求映射到具体的hessianservice -->
<bean id="urlMapping1"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/httpInvokerUserService.service">httpInvokerUserService</prop>
</props>
</property>
</bean>
<bean id="userServiceHttpInvoker" class="com.gosun.jws.httpinvoker.UserServiceImpl" />

配置DispatcherServlet控制器

<servlet>
　　<servlet-name>dispatcherServlet</servlet-name>
　　<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
　　<init-param>
　　　　<param-name>contextConfigLocation</param-name>
　　　　<param-value>classpath:applicationContext-httpinvoker.xml</param-value>
　　</init-param>
</servlet>
<servlet-mapping>
　　<servlet-name>dispatcherServlet</servlet-name>
　　<url-pattern>*.service</url-pattern>
</servlet-mapping>

客户端

配置Spring的HttpInvokerProxyFactoryBean

<bean id="httpInvokerUserService" class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
　　<property name="serviceUrl" value="http://localhost:8080/jws/httpInvokerUserService.service"/>
　　<property name="serviceInterface" value="com.gosun.jws.httpinvoker.UserService" />
</bean>

测试代码

import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.gosun.jws.daomain.Users;

public class ClientDemo {
public static void main(String[] args) {
ApplicationContext ac = new ClassPathXmlApplicationContext("client-application/applicationContext-httpInvoker.xml");
UserService us = (UserService) ac.getBean("httpInvokerUserService");
Users user = us.getUser("a001");
System.out.println(user.toJson());
System.out.println("----------------------------------------");
List<Users> users = us.geAlltUsers();
for (Users u : users) {
System.out.println(u.toJson());
}
System.out.println("----------------------------------------");
us.save(user);
System.out.println("----------------------------------------");
us.saves(users);
}
