我想編寫一個Web前端,希望將從瀏覽器接收到的HTTP認證「傳播」到暴露大量@Remote接口的JBoss AS 4.2.3。多個併發用戶對JBoss AS 4.2.3的RMI調用
考慮RMI調用併發以下瑣碎的模擬:
Properties user1 = new Properties();
user1.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.security.jndi.JndiLoginInitialContextFactory");
user1.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming");
user1.setProperty(Context.PROVIDER_URL, "127.0.0.1:1099");
user1.setProperty(Context.SECURITY_PRINCIPAL, "user1");
user1.setProperty(Context.SECURITY_CREDENTIALS, "pass1");
Properties user2 = new Properties();
user2.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.security.jndi.JndiLoginInitialContextFactory");
user2.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming");
user2.setProperty(Context.PROVIDER_URL, "127.0.0.1:1099");
user2.setProperty(Context.SECURITY_PRINCIPAL, "user2");
user2.setProperty(Context.SECURITY_CREDENTIALS, "pass2");
InitialContext ctx1 = new InitialContext(user1);
Mine bean1 = (Mine) ctx1.lookup("myear/MyBean/remote");
InitialContext ctx2 = new InitialContext(user2);
Mine bean2 = (Mine) ctx2.lookup("myear/MyBean/remote");
System.out.println(bean1.whoami());
System.out.println(bean2.whoami());
呼叫使用jbossall客戶端4.2.3並進入一個JBoss AS 4.2.3。
.whoami()方法簡單地回顯登錄的用戶名。當它變成我們的時候,這導致兩個電話都表示它們是由「user2」創建的。據推測,底層連接是共享的,只能使用上次看到的屬性包進行身份驗證。
總之,這很糟糕。一些初步的測試表明,同樣的問題仍然存在於JBoss AS 7中,所以沒有運氣。
是否有任何其他RMI客戶端實現我可以使用或任何參數我可以通過在prop捆綁使InitialContexts不共享他們的登錄信息?另外,有人可以指向我需要被黑客入侵的代碼,以使其成爲可能嗎?
UPDATE:
根據要求:
public class Worker extends Thread {
private final String pass, user;
private int correct = 0;
public Worker(String user, String pass) { this.user = user; this.pass = pass; }
public void run() {
Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.security.jndi.JndiLoginInitialContextFactory");
props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming");
props.setProperty(Context.PROVIDER_URL, "127.0.0.1:1099");
props.setProperty(Context.SECURITY_PRINCIPAL, this.user);
props.setProperty(Context.SECURITY_CREDENTIALS, this.pass);
try {
InitialContext ctx = new InitialContext(props);
for(int i = 0; i < 100; i++) {
Mine bean = (Mine) ctx.lookup("myear/MyBean/remote");
if(bean.whoami().equals(this.user)) this.correct++;
Thread.sleep(2); }
ctx.close();
} catch (Exception e) { throw new RuntimeException(e); }
System.out.println("Done [id="+this.getId()+", good="+this.correct+"]");
}
}
與兩個工人產量運行:
public static void main(String[] args) throws Exception {
new Worker("user1", "pass1").start();
new Worker("user2", "pass2").start();
}
Done [t=9, good=0]
Done [t=10, good=100]
用5個線程產量運行:
public static void main(String[] args) throws Exception {
new Worker("user1", "pass1").start();
new Worker("user2", "pass2").start();
new Worker("user3", "pass3").start();
new Worker("user4", "pass4").start();
new Worker("user5", "pass5").start();
}

使初始連接需要大約100毫秒,所以我嘗試以下(電話,睡10毫秒,以獲得良好的重疊):
public static void main(String[] args) throws Exception {
new Worker("user1", "pass1").start();
Thread.sleep(200);
new Worker("user2", "pass2").start();
Thread.sleep(200);
new Worker("user3", "pass3").start();
Thread.sleep(200);
new Worker("user4", "pass4").start();
Thread.sleep(200);
new Worker("user5", "pass5").start();
}
Done [t=9, good=1]
Done [t=14, good=12]
Done [t=15, good=14]
Done [t=16, good=15]
Done [t=17, good=100]
