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
@RemotingDestination
public class Foo
{
private static final Logger log = Logger.getLogger(Foo.class);

String name="failure";

String age="500";

public void init(String name, String age)
{
this.name=name;
this.age=age;
System.out.println(this.name+"---"+this.age);
}
public String getName()
{
System.out.println("getName:"+name);
return name;
}

public void setName(String name)
{
this.name = name;
}

public String getAge()
{
System.out.println("getAge:"+age);
return age;
}

public void setAge(String age)
{
this.age = age;
}

}
