1.需求：

　　记录展示每款产品的操作路径，操作账号，操作时间，便于管理。　解决：采用AOP结合自定义注解来实现记录用户的操作轨迹

2.代码实现：

　　AOP:

　　　　在面向切面编程的思想里面，把功能分为核心业务功能和周边功能。周边功能在Spring的面向切面编程AOP思想里，即被定义为切面。
　　核心业务功能和切面功能分别独立进行开发，然后把切面功能和核心业务功能 "编织" 在一起，这就叫AOP。

　1.自定义注解： 由于只是记录在哪个分类下做了什么操作，

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface Operation {
    String category() default "";//分类

    String type() default "";　　//操作
}

1 //分类属性值
2 public  final class OperationCategory {
3 
4     public static final String ALL= "全部"; 
5     public static final String SLIDE_SHOW="轮播图";
6     public static final String FEATURED_FIRST="推荐位";
7     public static final String PRODUCT_LIST="产品列表";
8 
9 }

 1 //操作属性值
 2 public class OperationType {
 3 
 4     public static final String NEWLY_INCREASED="新增";
 5     public static final String ADD="添加";
 6     public static final String UPDATE ="修改"; 
 7     public static final String PUTWAY_OR_SOLD_OUT ="上架/下架";
 8 //    public static final String SOLD_OUT= "下架";
 9     public static final String DELETE= "删除";
10     public static final String MOVE_UP= "上移";
11     public static final String MOVE_DOWN= "下移";
12     public static final String IS_TOP= "置顶";
13 }

2.切面：

  1 @Aspect
  2 @Component
  3 public class OperationAspect {
  4 
  5     @Autowired
  6     OperatorTrajectoryService operatorTrajectoryService;
  7 
  8     @Autowired
  9     CommodityCombinationMapper commodityCombinationMapper;
 10 
 11     @Autowired
 12     AdvertiseInfoMapper advertiseInfoMapper;
 13 
 14     @Autowired
 15     private HrpProductListInfoMapper hrpProductListInfoMapper;
 16 
 17     @Autowired
 18     private ProductInfoMapper productInfoMapper;
 19 
 20     /**
 21      * 定义切点 带有Operation注解的方法 都会被切入
 22      */
 23     @Pointcut("@annotation(com.tit.insurance.management.annotion.Operation)")
 24     public void operate() {
 25     }
 26 
 27     //执行 若使用注解的属性值 加上@annotation(operation)
 28     @After("operate()&&@annotation(operation)")
 29     public void doAfter(JoinPoint joinPoint, Operation operation) {
 30         System.out.println("******拦截后的逻辑******");
 31 
 32         // 获取传入目标方法的参数
 33         Object[] args = joinPoint.getArgs();
 34         for (int i = 0; i < args.length; i++) {
 35             System.out.println("第" + (i + 1) + "个参数为:" + args[i]);
 36         }
 37         //传入的参数是：广告、产品、推荐产品
 38         if (args[0] instanceof AdvertiseInfo) {
 39             AdvertiseInfo advertiseInfo = (AdvertiseInfo) args[0];
 40             OperationTrajectory operationTrajectory = new OperationTrajectory();
 41             operationTrajectory.setCategory(operation.category());
 42             operationTrajectory.setOperationAccount(
 43                     SecurityUtil.currentUser() == null ? "admin" : SecurityUtil.currentUser().getUsername());
 44             if (operation.type().equals(OperationType.PUTWAY_OR_SOLD_OUT)) {
 45                 operationTrajectory.setOperationType("0".equals(advertiseInfo.getIsUse()) ? "下架" : "上架");
 46             }
 47             else {
 48                 operationTrajectory.setOperationType(operation.type());
 49             }
 50             if (advertiseInfo.getId() != null) {
 51                 // 根据id查询指定软文信息
 52                 advertiseInfo = advertiseInfoMapper.selectByPrimaryKey(advertiseInfo.getId());
 53                 if (advertiseInfo.getCommodityCombinationId() != null) {
 54                     operationTrajectory.setProductCode(String.valueOf(advertiseInfo.getCommodityCombinationId()));
 55                     operationTrajectory.setProductName(advertiseInfo.getLinkTitle());
 56                 }
 57             }
 58             operationTrajectory.setOperationTime(new Date());
 59             operatorTrajectoryService.addOperation(operationTrajectory);
 60         }
 61         else if (args[0] instanceof HrpProductListInfo) {
 62             HrpProductListInfo productListInfo = (HrpProductListInfo) args[0];
 63             OperationTrajectory operationTrajectory = new OperationTrajectory();
 64             operationTrajectory.setCategory(operation.category());
 65             operationTrajectory.setOperationAccount(
 66                     SecurityUtil.currentUser() == null ? "admin" : SecurityUtil.currentUser().getUsername());
 67             if (operation.type().equals(OperationType.PUTWAY_OR_SOLD_OUT)) {
 68                 operationTrajectory.setOperationType("0".equals(productListInfo.getIsUse()) ? "下架" : "上架");
 69             }
 70             else {
 71                 operationTrajectory.setOperationType(operation.type());
 72             }
 73             if (productListInfo.getId() != null) {
 74                 // 根据id查询指定软文信息
 75                 HrpProductListInfo hrpProductListInfo = hrpProductListInfoMapper
 76                         .selectByPrimaryKey(productListInfo.getId());
 77                 if (hrpProductListInfo != null) {
 78                     operationTrajectory.setProductCode(hrpProductListInfo.getProductCode());
 79                     operationTrajectory.setProductName(hrpProductListInfo.getProductName());
 80                 }
 81             }
 82             operationTrajectory.setOperationTime(new Date());
 83             operatorTrajectoryService.addOperation(operationTrajectory);
 84         }
 85         else if (args[0] instanceof ProductInfo) {
 86             ProductInfo productInfo = (ProductInfo) args[0];
 87             OperationTrajectory operationTrajectory = new OperationTrajectory();
 88             operationTrajectory.setCategory(operation.category());
 89             operationTrajectory.setOperationAccount(
 90                     SecurityUtil.currentUser() == null ? "admin" : SecurityUtil.currentUser().getUsername());
 91             if (operation.type().equals(OperationType.PUTWAY_OR_SOLD_OUT)) {
 92                 operationTrajectory.setOperationType("0".equals(productInfo.getIsUse()) ? "下架" : "上架");
 93             }
 94             else {
 95                 operationTrajectory.setOperationType(operation.type());
 96             }
 97             if (productInfo.getId() != null) {
 98                 // 根据id查询指定软文信息
 99                 productInfo = productInfoMapper.selectByPrimaryKey(productInfo.getId());
100                 operationTrajectory.setProductCode(productInfo.getProductCode());
101                 operationTrajectory.setProductName(productInfo.getProductName());
102             }
103             operationTrajectory.setOperationTime(new Date());
104             operatorTrajectoryService.addOperation(operationTrajectory);
105         }
106     }
107 }

3.在需要编织的地方 加上自定义注解：

 1    /**
 2      * 广告新增
 3      * 
 4      * @param req
 5      * @param resp
 6      */
 7     @PostMapping("/addAdver")
 8     @ResponseBody
 9     //***********加上该自定义注解********
10     @Operation(category = OperationCategory.SLIDE_SHOW, type = OperationType.ADD)
11     public Status addAdverInfo(@RequestBody AdvertiseInfo advertiseInfo) {
12         Status status = new Status();
13         try {
14             advertiseService.addAdver(status, advertiseInfo);
15         }
16         catch (Exception e) {
17             status.setStatusCode("0");
18             status.setStatusMessage("【增加广告】参数解析异常！！！");
19             log.error("app新增广告失败！！！" + e.getMessage());
20         }
21         status.setTransTime(DateTime.getTimeString());
22         return status;
23     }

这样每当用户新增广告时候，aop就会记录向表中增加该条操作记录信息。
