本文介绍了如何使用自定义注解`@Operation`标记方法，配合切面编程创建操作日志切面`OperationAspect`，并以`OperationAccount`为例展示如何捕获参数和执行特定操作。通过实例化`OperationLog`来记录模块类型、操作类型和相关参数。

1：先自定义一个注解

在这里插入图片描述



@Documented
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Operation {
	/**
	 * 模块类型
	 */
	int moduleType();

	/**
	 * 具体操作
	 */
	int operateLogType() default 0;

	/**
	 * 一级菜单
	 */
	int operateMenuType() default 0;

	String operateContent() default "";
}

在这里插入图片描述

2：选择一个切面

@Slf4j
@Aspect
@Component
@AllArgsConstructor
@ApiModel(value = "操作日志切面")
public class OperationAspect {


//上面自定义的位置
	@Pointcut("@annotation(com.wotao.crm.handler.Operation)")
	public void logPointCut() {
	}

	@SneakyThrows
	@Around("logPointCut()")
	public Object around(ProceedingJoinPoint point) {

		Object proceed = point.proceed();
		try {
				saveOperation(point);

		} catch (Throwable throwable) {
			log.info("日志记录异常，不影响正常业务", throwable);
		}
		return proceed;
	}

	private void saveOperation(JoinPoint joinPoint) {
		// 获取方法上的注解
		MethodSignature signature = (MethodSignature) joinPoint.getSignature();
		Method method = signature.getMethod();
		Operation operation = method.getAnnotation(Operation.class);
		//获取controller里面的参数值
		Object[] args = joinPoint.getArgs();
		if (operation != null) {
			// 操作日志工厂类根据模块生成实例
			OperationLog operationLog = OperationLogFactory.getInstance(Objects.requireNonNull(OperationLogEnum.get(operation.moduleType())));
			// 批量操作需重复添加
			operationLog.add(operation, args, new OperateLog());
		}
	}
}


@Component
@AllArgsConstructor
public class OperationAccount extends AbstractOperation {
	@Override
	public R add(Operation operation, Object[] args, OperateLog log) {
		int operateLogType = operation.operateLogType();
		if (operateLogType == OperateLogConst.EDIT) {
			AccountDto dto = new AccountDto();
			BeanUtils.copyProperties(args[0], dto);
			Integer id = dto.getId();
			if (id != null) {
				log.setAssociationId(id.toString());
			}
		}
		if (operateLogType == OperateLogConst.EDIT_STATUS) {
			Integer accountId = 0;
			Integer status = 0;
			BeanUtils.copyProperties(args[0], accountId);
			BeanUtils.copyProperties(args[1], status);
			if (accountId != null && status != null) {
				log.setAssociationId("改变" + accountId.toString() + "的状态为:" + status.toString());
			}
		}
		return super.insertOperationLog(operation, log);
	}
}
