1.org.springframework.remoting.rmi.RmiProxyFactoryBean
其使用的是rmi协议实现
实现过程，首先是服务端
定义一个导出类

public
interface
AccountService {
String getUsername();
}

public
class
AccountServiceImpl
implements
AccountService{
@Override
public
String getUsername() {
return
"RMI Test!"
;
}
}

rmi.xml

<!-- 导出实体 -->
<

ref

<!-- 导出接口，这个为导出接口，注意，客户端包名可以和这里不同，但是为了统一建议做一个coreInterface

<

public
class
Main {
public
static
void
main(String[] args) {
ApplicationContext context =
new
ClassPathXmlApplicationContext(
"rmi.xml"
);
AccountService service = context.getBean(
"accountService"
, AccountService.
class
);
String userName = service.getUsername();
System.out.println(userName);
}
}

接下来客户端如下

|
public
interface
AccountService {
String getUsername();
}
|
rmi.xml

public

Main {
public

void
main(String[] args) {
ApplicationContext context =
new
ClassPathXmlApplicationContext(

);
AccountService service = context.getBean(
"accountService"
, AccountService.
class
);
String userName = service.getUsername();
System.out.println(userName);
}
}

这样就可以在服务器端得到了RMI Test!
当我们在启动服务端的时候会发现，其控制台一直在运行状态，当结束后，还会有rmi进程在运行。其接口协议为rmi://hostname:1199/xxxxxxx
