asyn4j -- 异步方法调用框架

asyn4j 是一个java异步方法调用框架，基于消费者与生产者模式。包括了异步方法执行，异步回调执行，异步工作缓存模块.支持Spring. 

让我们写异步方法不再写很多的相关多线程代码。用asyn4j轻松搞定异步方法调用.提高程序的响应能力. 



设计图 
 

1.调用普通方法  
主方法 

 public static void main(String[] args) {
         // 初始化异步工作服务
         AsynService asynService =  AsynServiceImpl.getService(300, 3000L, 3, 2);
         // 启动服务
         asynService.init();
         // 异步回调对象
         AsynCallBack back = new TargetBack();
         for (int i = 0; i < 1000; i++) {
                 // 添加加异步工作- TargetService 的 test 方法 ，方法参数 asynej+ i
                 asynService.addWork(new Object[] { "asyn4j" + i },
                                 TargetService.class, "test", new TargetBack());
                 //实例化目标对象再调用
                // TargetService targetService = new TargetService ();
                //asynService.addWork(new Object[] { "asyn4j" + i },
         //              targetService , "test", new TargetBack());

         }
 }

异步调用对象 

 public class TargetService {
         public String test(String name){
                 System.out.println(name +" test is execute!");
                 return name;
         }

 }

回调方法 

 //回调需继承AsynCallBack抽象类
 public class TargetBack extends AsynCallBack {

         @Override
         public void doNotify() {
                 //输出异步方法调用返回结果
                 System.out.println(this.methodResult);

         }

 }

2.调用Spring Bean的异步方法

 调用 Spring testBean 的 myName 方法
    applicationContext.xml 加入
     <bean id="springBeanUtil" class="com.googlecode.asyn4j.spring.AsynSpringUtil">
         </bean>

   <bean id="asynService" class="com.googlecode.asyn4j.spring.AsynServiceFactoryBean">

    </bean>


   public class TestMain {

         public AsynService asynService;

         public void setAsynService(AsynService asynService) {
                 this.asynService = asynService;
         }

         public void maintest(){
                 for(int i=0;i<10000;i++){
                         asynService.addWorkWithSpring(new Object[] { "panxiuyan" + i }, "testBean", "myName");
                 }
         }

 }

3.使用异步工作缓冲器  

 AsynService anycService = AsynServiceImpl.getService(300, 3000L, 100,
                                 100);
                 anycService.setWorkQueueFullHandler(new CacheAsynWorkHandler(100));
                 anycService.init();

当工作队列中的工作超过300个时，异步工作将由CacheAsynWorkHandler?处理; 

4.异步工作优级

 默认优先级为5  ,相关API
 //目标对象为指定实例
 public void addWork(Object[] params, Object tagerObject, String method,AsynCallBack asynCallBack, int weight);

 //目标对象为class
 public void addWork(Object[] params,Class clzss,String method,AsynCallBack asynCallBack,int weight);

 //Spring对应
 public void addWorkWithSpring(Object[] params,String target,String method,AsynCallBack asynCallBack,int weight);
