標準Java的RMI設置我所知道的有三種方式，其中第1、2種不區分框架均適用，但影響整個JVM級別的RMI服務

1.?啟動時設置sun.rmi.transport.tcp.responseTimeout，單位是毫秒

java?-Dsun.rmi.transport.tcp.responseTimeout=50

2.在應用程序中設置環境變量sun.rmi.transport.tcp.responseTimeout

System.setProperty("sun.rmi.transport.tcp.responseTimeout",?"5000")??單位也是毫秒

3.自定義socketfactory，具體用法參照官方這個指南

http://docs.oracle.com/javase/1.4.2/docs/guide/rmi/socketfactory/index.html

在Spring中，前面兩種都能生效，第三種有些地方需要注意

1.?在server端設置自定義的socket?factory

2.需要設置的是clientSocketFactory和serverSocketFactory這兩個屬性，而不是registryClientSocketFactory和registryServerSocketFactory，而且這兩個屬性要不全部設置，要不全部不設置，不能只設置一個

3.自定義的socketfactory必須實現Serializable接口(最好同時重寫hashCode和equals方法)

具體用法如下：

server端配置

RMICustomClientSocketFactory.java

public?class?RMICustomClientSocketFactory?implements?RMIClientSocketFactory,?Serializable?{

/**

*

*/

private?static?final?long?serialVersionUID?=?2879181835011310833L;

private?int?timeout;

/**

*?設置超時時間

*

*?@param?timeout

*/

public?void?setTimeout(int?timeout)?{

this.timeout?=?timeout;

}

@Override

public?Socket?createSocket(String?host,?int?port)?throws?IOException?{

Socket?socket?=?new?Socket();

socket.setSoTimeout(timeout);

socket.setSoLinger(false,?0);

socket.setKeepAlive(false);

socket.connect(new?InetSocketAddress(host,?port),?timeout);

return?socket;

}

}

RMICustomServerSocketFactory.java

public?class?RMICustomServerSocketFactory?implements?RMIServerSocketFactory,Serializable?{

/**

*

*/

private?static?final?long?serialVersionUID?=?8357061901854965297L;

private?int?timeout?=?17;

public?void?setTimeout(int?timeout)?{

this.timeout?=?timeout;

}

@Override

public?ServerSocket?createServerSocket(int?port)?throws?IOException?{

ServerSocket?serverSocket?=?new?ServerSocket(port);

serverSocket.setSoTimeout(timeout);

return?serverSocket;

}

}

在2.5.6和3.1.2中測試通過，另外在client端設置超時無效
