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);
