strtus中Interceptor和AbstractInterceptor区别

                                strtus中Interceptor和AbstractInterceptor区别 

Interceptor类

 

public interface Interceptor extends Serializable {

void destroy();

 

void init();

 

String intercept(ActionInvocation var1) throws Exception;

}

 

 

 

 

 

AbstractInterceptor类

 

public abstract class AbstractInterceptor implements Interceptor {

public AbstractInterceptor() {

}

 

public void init() {

}

 

public void destroy() {

}

 

public abstract String intercept(ActionInvocation var1) throws Exception;

}

 

 

 

 

 

 

AbstractInterceptor空实现了 init() 和destroy()，如果只需要intercept(ActionInvocation var1)可以继承AbstractInterceptor抽象类
