Hessian

    公司不同pool之间提供service都是通过hessian来开放接口的，个人觉得hessian的使用非常简单。做个demo如下：

0.首先创建web工程，并加载hessian.jar。

1.创建service，即我们通过它来提供接口：

1	public interface BasicService {

2

3	public void setServiceName(String serverName);

4

5	public String getServiceName();

6

7	public User createUser();

8

9

}

 

2.创建service实现：

01	public class BasicServiceImpl implements BasicService {

02

03	private String serviceName;

04

05

@Override

06	public void setServiceName(String serverName) {

07	this.serviceName = serverName;

08

}

09

10

@Override

11	public String getServiceName() {

12	return this.serviceName;

13

}

14

15

@Override

16	public User createUser() {

17	return new User("zhangsan", "123456");

18

}

19

}

3.创建需要通过hessian传递的对象（必须序列化）：

01	public class User implements Serializable {

02

03	private static final long serialVersionUID = 5792818254468116836L;

04

05	private String username;

06

07	private String password;

08

09	public User(String username, String password) {

10	this.username = username;

11	this.password = password;

12

}

13

14	public String getUsername() {

15	return username;

16

}

17

18	public void setUsername(String username) {

19	this.username = username;

20

}

21

22	public String getPassword() {

23	return password;

24

}

25

26	public void setPassword(String password) {

27	this.password = password;

28

}

29

}

4.配置web.xml:

01	<?xml version="1.0" encoding="UTF-8"?>

02	<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">

03	<display-name>HessianServer</display-name>

04

05

<servlet>

06	<servlet-name>basic</servlet-name>

07	<servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>

08	<init-param>

09	<param-name>service-class</param-name>

10	<param-value>com.loujinhe.service.impl.BasicServiceImpl</param-value>

11	</init-param>

12	</servlet>

13

14	<servlet-mapping>

15	<servlet-name>basic</servlet-name>

16	<url-pattern>/basic</url-pattern>

17	</servlet-mapping>

18

19	</web-app>

 

5.创建测试用例：

01	import java.net.MalformedURLException;

02

03	import org.junit.Before;

04	import org.junit.Test;

05

06	import com.caucho.hessian.client.HessianProxyFactory;

07	import com.loujinhe.service.BasicService;

08

09

10	public class BasicServiceTest {

11

12	private BasicService basicService;

13

14

@Before

15	public void init() throws MalformedURLException {

16	HessianProxyFactory factory = new HessianProxyFactory();

17	String url = "http://localhost:8080/HessianServer/basic";

18	basicService = (BasicService)factory.create(BasicService.class, url);

19

}

20

21

@Test

22	public void testBasic() {

23	basicService.setServiceName("BasicService");

24	System.out.println(basicService.getServiceName());

25

26	System.out.println(basicService.createUser().getUsername());

27	System.out.println(basicService.createUser().getPassword());

28

}

29

}

6.启动服务器，运行测试用例，会得到如下结果：

 

BasicService

zhangsan

123456
