Hessian Simple Use Summary

Hessian Introduction: Is a lightweight remoting onhttp tool that provides RMI functionality using a simple method. Simpler and faster than Webservice,hessian. The binary RPC protocol is used because the binary protocol is used, so it is good for sending binary data

1. Development environment MAVEN----SPRINGMVC

2.hessian need a customer service side of a server-side customer service and servers need to have Hessian jar using MAVEN directly add

<dependency>
<groupId>com.caucho</groupId>
<artifactId>hessian</artifactId>
<version>4.0.7</version>
</dependency>

The customer service side provides the final logic processing service side responsible for invoking the processing results of customer service

3. The customer terminal first defines an interface

Package com.test.hessian.images;

Public interface UserService {
public void AddUser ();

public void UpdateUser ();

public void Deluser ();

public string Finduser (string username);

}

Then implement this interface

Package com.test.hessian.images;

public class Userserviceimpl implements UserService {

public void AddUser () {
System.out.println ("-------------invoke AddUser ()---------------");
}

public void UpdateUser () {
System.out.println ("-------------invoke UpdateUser ()---------------");
}

public void Deluser () {
System.out.println ("-------------invoke Deluser ()---------------");
}

public string Finduser (string username) {
System.out.println ("-------------invoke Finduser---------------");
Return "return:" + username;
}

}

Then integrate the Hessian in the spring configuration file

<!--The bean mappings provided by the SPRINGMVC can also be used without--
<bean class= "org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<!--defines the interface implementation class for processing logic--
<bean id= "UserService" class= "Com.test.hessian.images.UserServiceImpl"/>
<!--name= "/userservice" is the access address of the service-side call (which is understood for the time being)---the specific class of service--processing logic-the interface of the Serviceinterface processing logic class ( The server side must also have this interface and the path and class name of the interface should be kept one at a time)-->
<bean name= "/userservice"
class= "Org.springframework.remoting.caucho.HessianServiceExporter" >
<property name= "service" ref= "UserService"/>
<property name= "Serviceinterface" value= "Com.test.hessian.images.UserService"/>
</bean>

4 service end (i.e., call side)

First define the same interface as the customer service side

Package com.test.hessian.images;

Public interface UserService {
public void AddUser ();

public void UpdateUser ();

public void Deluser ();

public string Finduser (string username);

}

Then configure the call in the SPRINGMVC configuration file

<bean id= "Userservicetoo"
class= "Org.springframework.remoting.caucho.HessianProxyFactoryBean" >
<property name= "serviceurl"
Value= "Http://127.0.0.1:8080/ldimages/userService"/>
<property name= "Serviceinterface" value= "Com.test.hessian.images.UserService"/>
</bean>

After these hessian are basically set up below is the test class

@RequestMapping ("/hessian/test/")
@Controller

public class Test {
@Autowired
@Qualifier ("Userservicetoo")
Private UserService UserService;


@RequestMapping ("index")
public void Main () {
Userservice.adduser ();
Userservice.updateuser ();
Userservice.deluser ();
String user = Userservice.finduser ("Zhangsan");
System.out.println ("Test.main ()----------" +user);
System.out.println ("---------------------------------finished----------------------------------");
}
}

Simple Hessain configuration success with this image server architecture is very good
