flex 与java交互问题总结

flex 与java交互是不可以使用构造函数去初始化java类的，即不可以使用函数直接初始化（如用户名、密码），因为flex new java类的时候是只实例化一次，也属于线程不安全的。

建议每次请求时必要传递该值

我的测试环境flex 4.6-spring?

以下是测试代码：

JAVA:

package com.gzhdi.csmp.service;

import org.apache.log4j.Logger;
import org.springframework.flex.remoting.RemotingDestination;
import org.springframework.stereotype.Service;


@Service

	String name="failure";

	String age="500";
