CORBA(Common Object Request Broker Architecture)與Java的結合使用,為構建分布式企業級應用提供了強大的解決方案。CORBA提供了跨語言、跨平台的互操作能力,而Java提供了可移植性和面向對象特性,兩者結合可構建高性能、可擴展的分布式系統。
// 定義IDL接口
module Finance {
interface Account {
float getBalance();
void deposit(in float amount);
void withdraw(in float amount);
};
};
// 服務端實現
public class AccountImpl extends AccountPOA {
private float balance;
public float getBalance() { return balance; }
public void deposit(float amount) { balance += amount; }
public void withdraw(float amount) { balance -= amount; }
}
// 客戶端調用
org.omg.CORBA.ORB orb = ORB.init(args, null);
org.omg.CORBA.Object obj = orb.string_to_object("corbaloc::host:port/Account");
Account account = AccountHelper.narrow(obj);
account.deposit(100.0f);
