Spring AOP - 無法執行方面

Question

我是Spring AOP和註解的新手。我試圖編寫一個使用Aspect的簡單程序。我無法弄清楚我出錯的地方。它不打印我在我的方面有什麼。

package com.business.main; 

import org.springframework.context.ApplicationContext; 
import org.springframework.context.annotation.AnnotationConfigApplicationContext; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.EnableAspectJAutoProxy; 

@EnableAspectJAutoProxy 
@Configuration 
public class PrintMain { 

    public static void main(String[] args) { 
     // Do I always need to have this. Can't I just use @Autowired to get beans 
     ApplicationContext ctx = new AnnotationConfigApplicationContext(PrintMain.class); 
     CheckService ck = (CheckService)ctx.getBean("service"); 
     ck.print(); 
    } 

    @Bean(name="service") 
    public CheckService service(){ 
     return new CheckService(); 
    } 

} 

package com.business.main; 

import org.aspectj.lang.annotation.Around; 
import org.aspectj.lang.annotation.Aspect; 
import org.springframework.stereotype.Component; 

@Aspect 
@Component 
public class SimpleAspect { 

    @Around("execution(* com.business.main.CheckService.*(..))") 
    public void applyAdvice(){ 
     System.out.println("Aspect executed"); 
    } 
} 

package com.business.main; 

import org.springframework.stereotype.Component; 

@Component 
public class CheckService{ 
    public void print(){ 
     System.out.println("Executed service method"); 
    } 
} 

輸出：執行的服務方法

我希望打印的內容我在我的看點

我覺得你是@Component不行！
也許，你需要的@ComponentScan

@EnableAspectJAutoProxy 
@ComponentScan 
@Configuration 
public class PrintMain { 

    public static void main(String[] args) { 
     // Do I always need to have this. Can't I just use @Autowired to get beans 
     ApplicationContext ctx = new AnnotationConfigApplicationContext(TNGPrintMain.class); 
     CheckService ck = (CheckService)ctx.getBean("service"); 
     ck.print(); 
    } 

    @Bean(name="service") 
    public CheckService service(){ 
     return new CheckService(); 
    } 

}
