Dubbo服务者

创建代理对象

com.alibaba.dubbo.config.ServiceConfig#export

通过消费者export()方法可以找到以上方法，消费者需要根据配置的接口生成代理对象。 ###生成Invoker

1以上通过工厂生成服务者的Invoker，Wrapper.getWrapper里面通过接口生成新Wrapper及接口的实现。
2生成的具体代码
3public class AClass$sw1 extends Wrapper {
4
5	public static String[] pns;
6	public static Map pts;
7	public static String[] mns;
8	public static String[] dmns;
9	public static Class[] mts0;
10	public static Class[] mts1;
11	
12
13	public AClass$sw1() {
14	}
15	
16	public String[] getPropertyNames(){ return pns; }
17	
18	public boolean hasProperty(String n){ return pts.containsKey(n); }
19	
20	public Class getPropertyType(String n){ return (Class)pts.get(n); }
21	
22	public String[] getMethodNames(){ return mns; }
23	
24	public String[] getDeclaredMethodNames(){ return dmns; }
25	
26	public void setPropertyValue(Object o, String n, Object v){ 
27	 AClass w; 
28	 try{ 
29	 		w = ((AClass)o); 
30	 }catch(Throwable e){ 
31	 		throw new IllegalArgumentException(e); 
32	 }
33	 if( n.equals("field1") ){ 
34	 		w.field1=((Boolean) v).booleanValue(); 
35	 		return; 
36	 }
37	 if( n.equals("field2") ){ 
38	 		w.field2=((Boolean) v).booleanValue(); 
39	 		return; 
40	 }
41	 throw new NoSuchPropertyException("Not found property $2 filed or setter method in class AClass."); 
42	}
43	 
44	public Object getPropertyValue(Object o, String n){
45		AClass w; 
46		try{ 
47			w = ((AClass)o); 
48		}catch(Throwable e){ 
49			throw new IllegalArgumentException(e); 
50		}
51		if( n.equals("field1") ){ 
52			return ($w)w.field1; 
53		}
54		if( n.equals("field2") ){ 
55			return ($w)w.field2; 
56		}
57		// getField11
58		if( n.equals("field11") ){ 
59			return ($w)w.getField11(); 
60		}
61		// isField21|hasField21|canField21
62		if( n.equals("field21") ){ 
63			return ($w)w.isField21(); 
64		}
65		throw new NoSuchPropertyException("Not found property $2 filed or setter method in class AClass."); 
66	}
67	
68	public Object invokeMethod(Object o, String n, Class[] p, Object[] v) throws InvocationTargetException {
69		AClass w; 
70		try{ 
71			w = ((AClass)o); 
72		}catch(Throwable e){ 
73			throw new IllegalArgumentException(e); 
74		}
75		try{
76			if( "method1".equals( n ) && p.length ==  &&  p[0].getName().equals("Boolean") &&  p[1].getName().equals("Integer") ) { 
77			 return ($w)w.method1(((Boolean)v[0]).booleanValue(), ((Number)v[1]).intValue());
78			}
79		} catch(Throwable e) {
80		     throw new java.lang.reflect.InvocationTargetException(e); 
81		}
82		throw new NoSuchMethodException("Not found method n in class AClass."); 
83	}
84}

服务者生成了对应的Invoker，通过DubboProtocol暴露Exporter。
