基于SSM利用SpringAOP切面及自定义注解 记录每次操作记录(操作日志 同理)

       前段时间根据业务需求要记录每次操作时的相关信息:本帖方式通过在SpringMVC中的Controller设置一个自定

义注解类来进行对数据的接收,通过 SpringAOP切面来对接收的数据进行逻辑处理.在事先根据业务需求创建的一个

实体类(如: UploadCount)的基础上：

1.首先springmvc.xml进行配置

2.根据业务需求创建自定义注解类

@Retention(RetentionPolicy.RUNTIME)  
@Target(ElementType.METHOD)
@Documented
public @interface UploadCountLogs {
	String moduleName() default "";   //自定义参数
}

3.创建一个对接收到的数据进行逻辑处理的切点类

/**  
 * 切点类  
 * @author shilei
 * @version 1.0  
 */    
@Aspect    
@Component    
public class UploadCountLogsAspect{    
	//注入Service用于把上传记录的相关数据信息保存到数据库    
	@Autowired    
	private SchemeProposalsService schemeProposalsService;
	@Autowired
	private UserRedisUtils userRedisUtils;
	
	//本地异常日志记录对象    
	//private  static  final Logger logger = LoggerFactory.getLogger(UploadCountLogsAspect. class);

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

	/**  
	 * 前置通知 用于拦截Controller层 获取记录的操作信息  
	 *  
	 * @param joinPoint 切点  
	 */    
	@Before("controllerAspect()")    
	public void doBefore(JoinPoint joinPoint) {    

		HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();    
		User user = userRedisUtils.getUser(request); 
		try {
             //具体业务逻辑  根据业务需求进行更改
			UploadCount count = new UploadCount();
			count.setTid(UUID.randomUUID().toString());
			count.setModuleName(getControllerMethodDescription(joinPoint)[0]);
			count.setCreateUid(user.getUserId().toString());
			count.setDeptId(user.getDeptId());
			count.setDeptName(user.getDept());
			//保存数据库    
			schemeProposalsService.addRecord(count);
		}  catch (Exception e) {    
			e.printStackTrace();
		}    
	}       

	/**  
	 * 获取注解中对方法的描述信息 用于Controller层注解  
	 *  
	 * @param joinPoint 切点  
	 * @return 方法描述  
	 * @throws Exception  
	 */    
	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();
				     //具体的业务逻辑  根据业务需求进行更改
                                  if(annos[0].equals("新闻")){
				        Random random = new Random();
					int ran = random.nextInt(30);  //[0,30)
					if (ran<10) {
						annos[0]="政务公示";
					}else if (ran>=10 && ran<20) {
						annos[0]="政府舆情";
					}else {
						annos[0]="新闻数据";
					}
				  }
					break;    
			     }    
			}    
		}    
		return annos;    
	}    
}

4.最后在Controller加上自定义注解类,完成!!!   

       @UploadCountLogs(moduleName="新闻")
