前段時間根據業務需求要記錄每次操作時的相關資訊:本帖方式通過在SpringMVC中的Controller設定一個自定義註解類來進行對資料的接收,通過 SpringAOP切面來對接收的資料進行邏輯處理.

在事先根據業務需求建立的一個實體類(如: UploadCount)的基礎上:

1.首先springmvc.xml進行配置

<!-- 啟動AOP AspectJ註解自動代理 --> 
<aop:aspectj-autoproxy proxy-target-class="true"/>
<!-- 指定自定義註解類的路徑 及 配置在Controller上新增自定義註解來接收資料 --> 
<context:component-scan base-package="com.sl.api.common.util.aopUtils">
       <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
 

@Retention(RetentionPolicy.RUNTIME)  
@Target(ElementType.METHOD)
@Documented
public @interface UploadCountLogs {
	String moduleName() default "";   //自定義引數
}

/**  
 * 切點類

@Aspect    
@Component    
public class UploadCountLogsAspect{    
	//注入Service用於把上傳記錄的相關資料資訊儲存到資料庫    
	@Autowired    
	private SchemeProposalsService schemeProposalsService;
	@Autowired
	private UserRedisUtils userRedisUtils;
	
	//本地異常日誌記錄物件    
	//private  static  final Logger logger = LoggerFactory.getLogger(UploadCountLogsAspect. class);

	//Controller層切點    
	@Pointcut("@annotation(com.sl.api.common.util.aopUtils.UploadCountLogs)")
	public void controllerAspect() {
		 System.out.println("切入點...");
	}    

	/**  
	 * 前置通知 用於攔截Controller層 獲取記錄的操作資訊

             //具體業務邏輯  根據業務需求進行更改
			UploadCount count = new UploadCount();
			count.setTid(UUID.randomUUID().toString());

	 */    
	public  static String[] getControllerMethodDescription(JoinPoint joinPoint)  throws Exception {    
		String targetName = joinPoint.getTarget().getClass().getName();    
		String methodName = joinPoint.getSignature().getName();    
		Object[] arguments = joinPoint.getArgs();    
		Class targetClass = Class.forName(targetName);    
		Method[] methods = targetClass.getMethods();   
		String[] annos = {""};
		for (Method method : methods) {    
			if (method.getName().equals(methodName)) {    
				Class[] clazzs = method.getParameterTypes();    
				if (clazzs.length == arguments.length) {    
				     annos[0] = method.getAnnotation(UploadCountLogs.class).moduleName();
				     //具體的業務邏輯  根據業務需求進行更改
                  if(annos[0].equals("新聞")){
				    Random random = new Random();
					int ran = random.nextInt(30);  //[0,30)
					if (ran<10) {
						annos[0]="政務公示";
					}else if (ran>=10 && ran<20) {
						annos[0]="政府輿情";
					}else {
						annos[0]="新聞資料";
					}
				  }
					break;    
			     }    
			}    
		}    
		return annos;    
	}    
}
 

4.最後在Controller加上自定義註解類,完成!!!   

       @UploadCountLogs(moduleName="新聞")
