查询契约间隔时间，单位为ms，默认值 是java.rmi.dgc.leaseValue值的一半。
优化：尽早的删除引用有利于管理内存，但leaseValue太短的话又会造成网络风险。

标准Java的RMI设置我所知道的有三种方式，其中第1、2种不区分框架均适用，但影响整个JVM级别的RMI服务
1. 启动时设置sun.rmi.transport.tcp.responseTimeout，单位是毫秒
    java -Dsun.rmi.transport.tcp.responseTimeout=50 
2.在应用程序
server里面的报错信息：
ERROR [RMI TCP Connection(3)-127.0.0.1] - dataSource init error
