spring-boot - 使用 Spring AOP 在 mongoDb 中存储新旧值

Question

我是 Spring AOP 世界的新手。我正在尝试使用 AOP 构建 Spring 引导日志记录。我在 MongoDB 中创建了名为“Audit report”的集合，它存储对象的旧值和更新值。为此，我正在使用 Spring AOP 的 @Before 和 @After 注解。假设我必须编辑该对象，那么它的先前名称和更新后的名称应该输入到数据库中。

这是我的审计报告类，

@Data
@Document(collection="auditReport")
public class AuditReport extends AuditEntity {
    private String description;
    private String old_value;
    private String new_value;
}

这个id实体类，

public class AuditEntity {
     @Field("createdDate")
     @CreatedDate
     private Date createdDate;

     @Field("createdBy")
     @CreatedBy
     private String createdBy;

     @Field("updatedDate")
     @LastModifiedDate
     private Date updatedDate;

     @Field("updatedBy")
     @LastModifiedBy
     private String updatedBy;

     @Field("version")
     @Version
     private Long version;
}

这是我的方面类，

@Before("execution(* com.controller.DeliveryMethodsController.edit*(..)) && target(instance) && args(deliveryMethodObject) ")
    public void before(JoinPoint joinPoint,Object instance,DeliveryMethods deliveryMethodObject) throws Exception {
        LOGGER.info("Entering inside Aspect "+ joinPoint.getSignature().getName());

        Object[] signatureArgs = joinPoint.getArgs();
        LOGGER.info("Input: ",signatureArgs.toString());
        String methodName = joinPoint.getSignature().getName();
        Object previous = instance.getClass().getMethod(methodName.replaceFirst("edit", "get")).invoke(deliveryMethodObject);

        AuditReport report = new AuditReport();
        String prop = joinPoint.getSignature().getName().substring(4);
        Object target = joinPoint.getTarget();
        Object before = target.getClass().getMethod("get" + prop).invoke(deliveryMethodObject);
        Object now = joinPoint.getArgs()[0];
        System.out.println(prop + " changed from " + before + " to " + now);
        report.setDescription(joinPoint.getSignature().getName());
        System.out.println("DM object "+deliveryMethodObject);
        System.out.println(" report "+report);
        audiRepo.save(report);
    }

当我试图编辑 DeliveryMethod 时，我正在使用 get 方法获取以前的记录，该方法具有相同的参数，即 Id。但它给了我这样的错误，

这是我的 Controller 类，

@RestController
@RequestMapping(value="/deliveryMethods")
public class DeliveryMethodsController {

    private static final Logger logger = LoggerFactory.getLogger(DeliveryMethodsController.class);

    @Autowired
    private DeliveryMethodService deliveryMethodService;

    @Autowired
    public DeliveryMethodsController(DeliveryMethodService deliveryMethodService){
        super();
    }

    @RequestMapping(value = "/createDeliveryMethod", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> createDeliveryMethod(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside create delivery Method", deliveryMethodObject);
        return deliveryMethodService.createDeliveryMethod(deliveryMethodObject);
    }

    @RequestMapping(value = "/getActiveDeliveryMethod", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> getActiveDeliveryMethod(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside getAll active delivery methods method", deliveryMethodObject);
        return deliveryMethodService.getActiveDeliveryMethod(deliveryMethodObject);
    }

    @RequestMapping(value = "/getDeliveryMethod", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> getDeliveryMethod(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside getAll delivery methods method", deliveryMethodObject);
        return deliveryMethodService.getDeliveryMethod(deliveryMethodObject);
    }

    @RequestMapping(value = "/getDeliveryMethodById", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> getDeliveryMethodById(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside get delivery methods by Id method", deliveryMethodObject);
        return deliveryMethodService.getDeliveryMethodById  (deliveryMethodObject);
    }

    @RequestMapping(value = "/editDeliveryMethodById", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> editDeliveryMethodById(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside edit delivery methods by Id method", deliveryMethodObject);
        return deliveryMethodService.editDeliveryMethodById  (deliveryMethodObject);
    }

    @RequestMapping(value = "/deleteDeliveryMethod", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> deleteDeliveryMethod(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside delete delivery methods by Id method", deliveryMethodObject);
        return deliveryMethodService.deleteDeliveryMethod(deliveryMethodObject);
    }

    @RequestMapping(value = "/enableOrDisabledDeliveryMethod", method = RequestMethod.POST, consumes = "application/json;charset=UTF-8",produces = "application/json;charset=UTF-8")
    public ResponseEntity<BaseEntityResponse<DeliveryMethods>> enableOrDisabledDeliveryMethod(@RequestBody DeliveryMethods deliveryMethodObject) {
        logger.debug("Entering inside enable or disable delivery methods by Id method", deliveryMethodObject);
        return deliveryMethodService.enableOrDisabledDeliveryMethod(deliveryMethodObject);
    }
}

这是模型类，

public class DeliveryMethods extends AuditEntity implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @Field("methodId")
    private String methodId;

    @Field("deliveryMethodName")
    private String deliveryMethodName;

    @Field("displayLabel")
    private String displayLabel;

    @Field("serviceType")
    private String serviceType;

    @Field("courierService")
    private List<Object> courierService;

    @Field("address")
    private List<Object> address;


    @Field("isActive")
    private boolean isActive;

    @Field("deliveryAddress")
    private String deliveryAddress;


    @Field("isDeleted")
    private boolean isDeleted;

    @Field("selectedIncart")
    private boolean selectedIncart;

    @Field("createdOn")
    @JsonSerialize(using = LocalDateTimeSerializer.class)
    @JsonDeserialize(using = LocalDateTimeDeserializer.class)
    private LocalDateTime createdOn;
}

但是这个方法存在于我的 Controller 中。谁能建议我解决这个问题？或者建议我在编辑对象时获取旧值的替代方法。提前致谢。

Answer 1

很难让它运行，因为缺少很多类和注释，而且没有 MCVE从中克隆。此外，您的代码似乎以不同的方式两次检索旧值并将它们存储在不同的变量 before 和 previous 中。我删除了冗余，重命名并重新组织了一些变量，以便更清楚地了解它是什么，并将记录器的使用更改为仅在控制台上打印(您可以轻松地将其改回)。另外，你没有展示完整的方面，所以我不知道 audiRepo 来自哪里。我创建了许多虚拟类和注释来让一切正常运行。

  @Before("execution(* com.controller.DeliveryMethodsController.edit*(..)) && target(instance) && args(deliveryMethods)")
  public void beforeAdvice(JoinPoint joinPoint, Object instance, DeliveryMethods deliveryMethods) throws Exception {
    System.out.println(joinPoint);
    String editMethodName = joinPoint.getSignature().getName();
    String getterMethodName = editMethodName.replaceFirst("edit", "get");
    Method getterMethod = instance.getClass().getMethod(getterMethodName, DeliveryMethods.class);
    Object oldValue = getterMethod.invoke(instance, deliveryMethods);
    String propertyName = editMethodName.substring(4);

    AuditReport report = new AuditReport();
    report.setDescription(editMethodName);
    report.setOld_value(oldValue.toString());
    report.setNew_value(deliveryMethods.toString());
    System.out.println("Report " + report);
    audiRepo.save(report);
  }

对于我的虚拟对象，这会打印:

execution(ResponseEntity com.controller.DeliveryMethodsController.editDeliveryMethodById(DeliveryMethods))
Entering inside get delivery methods by Id method = com.controller.DeliveryMethods@63961c42
Report AuditReport [description=editDeliveryMethodById, old_value=com.controller.ResponseEntity@65b54208, new_value=com.controller.DeliveryMethods@63961c42]
Entering inside edit delivery methods by Id method = com.controller.DeliveryMethods@63961c42

当然，对于您来说，输出看起来有点不同，因为旧值和新值不仅仅是虚拟对象。

你的主要问题是反射的使用:

• 您不仅需要设置名称，还需要在 getMethod(..) 中设置所有参数的类。
• 您还需要为 invoke(..) 提供实例，而不仅仅是参数。

另请注意

• 目前 propertyName 在我的示例代码中未使用，因为我删除了使用它的日志行，
• 旧值 oldValue 和新值 deliveryMethods 是不同的类型，可能都是围绕已更改的实际值的不同类型的包装对象。没有看到完整的代码我不能说，这让我觉得有点奇怪。
