注意事项
▲JAVA服务器端必须具备以下几点：
---->包含Hessian的jar包
---->设计一个接口，用来给客户端调用
---->实现该接口的功能
---->配置web.xml，配好相应的servlet
---->对象必须实现Serializable 接口
---->对于复杂对象可以使用Map的方法传递
▲客户端必须具备以下几点：
---->java客户端包含Hessian.jar的包。C#中引用hessianCSharp.dll
---->具有和服务器端结构一样的接口。包括命名空间都最好一样
---->利用HessianProxyFactory调用远程接口。
服务器端（向外暴漏接口的应用）
【1】配置该web应用的web.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <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_2_5.xsd" id="WebApp_ID" version="2.5"> 3 <!-- 以下3项参数与log4j的配置相关 --> 4 <!-- start --> 5 <context-param> 6 <param-name>log4jConfigLocation</param-name> 7 <param-value>/WEB-INF/log4j.properties</param-value> 8 </context-param> 9 10 <context-param> 11 <param-name>log4jRefreshInterval</param-name> 12 <param-value>60000</param-value> 13 </context-param> 14 <listener> 15 <listener-class> 16 org.springframework.web.util.Log4jConfigListener 17 </listener-class> 18 </listener> 19 <!-- end --> 20 21 <!-- 一个web.xml中可以配置多个DispatcherServlet,通过 servlet-mapping的不同设置，让每个DispatcherServlet处理不同的请求--> 22 23 <!-- 业务层和持久层的bean的spring配置文件。applicationContext.xml.多个配置文件使用，号隔开--> 24 <context-param> 25 <param-name>contextConfigLocation</param-name> 26 <param-value>classpath:/spring-mybatis/spring-mybatis.xml</param-value> 27 </context-param> 28 29 <!-- 配置Spring监听 。通过contextConfigLocation配置的xml文件启动业务层（service和dao)的bean的容器。【service层和dao层的容器】--> 30 <!-- spring的监听器 --> 31 <listener> 32 <description>spring监听器</description> 33 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 34 </listener> 35 36 37 <!-- 暴露hessian接口的servlet --> 38 <servlet> 39 <servlet-name>hessian</servlet-name> 40 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 41 <!-- 此处加载的hessin-servlet.xml必须是该格式【servlet的名字】-servlet.xml。如果非该格式，报错 --> 42 <init-param> 43 <param-name>contextConfigLocation</param-name> 44 <param-value>classpath:/hessian-remote/hessian-servlet.xml</param-value> 45 </init-param> 46 <load-on-startup>1</load-on-startup> 47 </servlet> 48 49 <servlet-mapping> 50 <servlet-name>hessian</servlet-name> 51 <url-pattern>/hessian/*</url-pattern> 52 </servlet-mapping> 53 54 55 </web-app>
【2】hessian的接受器配置。hessian-servlet.xml的配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xsi:schemaLocation=" 5 http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 7 http://www.springframework.org/schema/tx 8 http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 9 http://www.springframework.org/schema/aop 10 http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 11 http://www.springframework.org/schema/context 12 http://www.springframework.org/schema/context/spring-context-3.2.xsd"> 13 14 <!-- 主体的扫描除controller外的所有组件 --> 15 <context:component-scan base-package="org.paymoney.*" > 16 <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> 17 <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/> 18 </context:component-scan> 19 <!-- 配置数据源 --> 20 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" > 21 <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> 22 <property name="url" value="jdbc:mysql://localhost:3306/test"></property> 23 <property name="username" value="root"></property> 24 <property name="password" value="1234"></property> 25 </bean> 26 27 28 <!-- 配置事务管理器 --> 29 <bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 30 <property name="dataSource" ref="dataSource" /> 31 </bean> 32 33 34 <!-- 注解方式配置事物 proxy-target-class="true" 值为true时选用cglib动态代理，事务注解放置具体类的方法上， 值为false为jdk动态代理管理事务，事务注解放置接口方法上 --> 35 <tx:annotation-driven transaction-manager="transactionManager" /> 36 37 <!--注解风格支持,当带事务注解的业务类中方法自调用时，为了防止事务失效--> 38 <aop:aspectj-autoproxy expose-proxy="true"/> 39 40 <!-- mybatis文件 --> 41 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 42 <!-- 数据源。数据库连接 --> 43 <property name="dataSource" ref="dataSource" /> 44 <!-- 扫描该包下的类，给每一个javaBean起一个别名，别名是首字母小写的javaBean类名 --> 45 <property name="typeAliasesPackage" value="org.paymoney.comment" /> 46 <!-- 自动扫描entity目录，省略Configuration.xml里手工配置 --> 47 <property name="mapperLocations" value="classpath*:/org/paymoney/mapper/*.xml" /> 48 <!-- 暂定不知道该配置对不 --> 49 <!-- <bean id="sqlSession"class="org.mybatis.spring.SqlSessionTemplate"> --> 50 </bean> 51 52 <!-- 接口实例化管理的bean --> 53 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 54 <property name="basePackage" value="org.paymoney.dao" /> 55 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> 56 </bean> 57 </beans>
【4】暴漏的接口实现类
1 import java.util.Date; 2 3 import javax.annotation.Resource; 4 5 import org.paymoney.comment.Order; 6 import org.paymoney.dao.OrderMapper; 7 import org.paymoney.port.OrderService; 8 import org.springframework.stereotype.Service; 9 import org.springframework.transaction.annotation.Propagation; 10 import org.springframework.transaction.annotation.Transactional; 11 12 @Service(value="orderService") 13 public class OrderServiceImpl implements OrderService{ 14 15 @Resource 16 private OrderMapper orderMapper; 17 18 //说你好 19 @Override 20 @Transactional(propagation=Propagation.REQUIRED) 21 public void sayHello(String name, Integer age, Date brithday) { 22 // TODO Auto-generated method stub 23 System.out.println("OrderServiceImpl.sayHello():姓名--->"+name+" 年龄--->"+age+" 生日-->"+brithday.toString()); 24 25 } 26 27 //添加一个订单 28 @Override 29 @Transactional(propagation=Propagation.REQUIRED) 30 public void addOrder(Order order) { 31 System.out.println("OrderServiceImpl.addOrder(添加订单前)"); 32 orderMapper.addOrder(order); 33 System.out.println("OrderServiceImpl.addOrder(添加订单后)"); 34 35 } 36 37 38 }
客户端（需要调用另一个应用接口的项目）
【1】配置该web应用的web.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <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_2_5.xsd" id="WebApp_ID" version="2.5"> 3 <display-name>json_test</display-name> 4 <welcome-file-list> 5 <welcome-file>login.jsp</welcome-file> 6 </welcome-file-list> 7 8 <!-- 一个web.xml中可以配置多个DispatcherServlet,通过 servlet-mapping的不同设置，让每个DispatcherServlet处理不同的请求--> 9 10 <!-- 业务层和持久层的bean的spring配置文件。applicationContext.xml.多个配置文件使用，号隔开 11 此处加载spring-hessianclient.xml 12 --> 13 <context-param> 14 <param-name>contextConfigLocation</param-name> 15 <param-value>classpath*:/spring-*.xml</param-value> 16 </context-param> 17 18 <!-- 配置Spring监听 。通过contextConfigLocation配置的xml文件启动业务层（service和dao)的bean的容器。【service层和dao层的容器】--> 19 <!-- spring的监听器 --> 20 <listener> 21 <description>spring监听器</description> 22 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 23 </listener> 24 25 26 <!-- Spring的log4j监听器 --> 27 <listener> 28 <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> 29 </listener> 30 <!-- 防止spring内存溢出监听器 --> 31 <listener> 32 <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> 33 </listener> 34 35 <!-- 配置SpringMVC的DispatcherServlet ，它是springmvc的灵魂和心脏，它协调各组件完成一次完整的请求响应--> 36 <!-- （默认自动加载web-inf下的<servltname>-servlet.xml的spring配置文件）启动web层的spring容器【控制器,请求分发器】 --> 37 <!-- 如果配置init-param则是打破默认自动加载，而是按param-value中的路径，加载web层容器 --> 38 <!-- web层的spring容器是业务层的spring容器的子容器：即web层容器中的bean【controller】可以调用业务层bean【service和dao】而业务层bean调用不到web层的bean --> 39 <servlet> 40 <servlet-name>springMVC</servlet-name> 41 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 42 <init-param> 43 <!-- 装配webApplicationContext容器。其实ApplicationContext容器的子类--> 44 <param-name>contextConfigLocation</param-name> 45 <param-value>classpath*:/spring-mvc.xml</param-value> 46 </init-param> 47 <load-on-startup>1</load-on-startup> 48 </servlet> 49 <servlet-mapping> 50 <servlet-name>springMVC</servlet-name> 51 <url-pattern>/</url-pattern> 52 </servlet-mapping> 53 54 <!-- 配置字符集 --> 55 <filter> 56 <filter-name>encodingFilter</filter-name> 57 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 58 <init-param> 59 <param-name>encoding</param-name> 60 <param-value>UTF-8</param-value> 61 </init-param> 62 <init-param> 63 <param-name>forceEncoding</param-name> 64 <param-value>true</param-value> 65 </init-param> 66 </filter> 67 <filter-mapping> 68 <filter-name>encodingFilter</filter-name> 69 <url-pattern>/*</url-pattern> 70 </filter-mapping> 71 72 </web-app>
【2】客户端需要配置的spring-hessianclient.xml
1 <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> 2 <beans> 3 <!-- 客户端Hessian代理工厂Bean --> 4 <bean id="hessianFactory" class="org.springframework.remoting.caucho.HessianProxyFactoryBean"> 5 <!-- 请求代理Servlet路径 --> 6 <property name="serviceUrl"> 7 <!-- 需要请求暴漏接口的服务地址。http://ip/服务应用名/hessian的servlet名字/请求的标示 --> 8 <value>http://localhost:8081/paymoney-hessian/hessian/hessianOrder</value> 9 </property> 10 <!-- 接口定义 --> 11 <property name="serviceInterface"> 12 <value>org.paymoney.port.OrderService</value> 13 </property> 14 </bean> 15 </beans>
【3】客户端业务类中的远程调用接口
1 /** 2 * 测试hessian 3 */ 4 public void testHessian() { 5 // TODO Auto-generated method stub 6 //从applicationContext容器中获取hessianfacttory 7 OrderService orderService=(OrderService) context.getBean("hessianFactory"); 8 9 Date aDate=new Date(); 10 //调用远程方法 11 orderService.sayHello("sxf", 25,aDate); 12 Order order=new Order(); 13 order.setOrderNum(1234); 14 order.setCompanyName("易宝"); 15 order.setPersonName("尚晓飞"); 16 order.setOrderTime(aDate); 17 //调用远程方法 18 orderService.addOrder(order); 19 System.out.println("AuthorServiceImpl.testHessian()"); 20 21 }
【4】也可以通过另一种方式调用远程方法。
1 public static void main(String[] args) throws MalformedURLException { 2 //远程调用路径 3 String url = "http://localhost:8081/paymoney-hessian/hessian/hessianOrder"; 4 //hessianproxyFactory的工厂对象。 5 HessianProxyFactory factory = new HessianProxyFactory(); 6 //获取远程调用的接口代理对象 7 OrderService orderService = (OrderService) factory.create(OrderService.class, url); 8 9 Date gDate=new Date(); 10 //调用远程方法 11 orderService.sayHello("123", 25,gDate); 12 13 Order order=new Order(); 14 order.setOrderNum(5201314); 15 order.setCompanyName("天天向上"); 16 order.setOrderTime(gDate); 17 order.setPersonName("尚晓飞"); 18 //调用远程方法 19 orderService.addOrder(order); 20 21 }
