使用 Spring AOP 在 mongoDb 中存储新旧值答案

【问题标题】：Storing old and new value in mongoDb using Spring AOP使用 Spring AOP 在 mongoDb 中存储新旧值
【发布时间】：2019-02-08 12:59:15
【问题描述】：

我是 Spring AOP 世界的新手。我正在尝试使用 AOP 构建 Spring Boot 日志记录。我在 MongoDB 中创建了一个名为“Audit report”的集合，它存储对象的旧值和更新值。我正在为此使用 Spring AOP 的 @Before 和 @After 注解。假设我必须编辑该对象，因此应将其以前的名称和更新后的名称输入到数据库中。

这是我的审计报告课，

@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);
    }

当我尝试编辑 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，

这是我的控制器类，

@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控制器中。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。

【问题讨论】：

反射的东西看起来有点难看，但除此之外：我猜你的方法需要一个参数（ID），但你正在寻找一个没有参数的方法。如果有帮助，请告诉我，我会将评论转换为您可以接受的答案。
我已经将参数添加到方法中，例如 Object before = target.getClass().getMethod("get" + prop).invoke(deliveryMethodObject);你能告诉我传递参数的确切方法吗？
见Javadoc。我还没有执行你的代码，但我认为你应该写.invoke(instance, deliveryMethodObject)。我没有检查您的代码中是否还有其他缺点。如果这不能解决您的问题，请告诉我，我可以将代码复制到我的 IDE 中并尝试运行它。
你好 Kriegaex，我已经尝试过了，但没有工作。我得到的仍然是“NoSuchMethodException”错误。你能帮帮我吗？。
当然，如果我能重现您的问题。但是在您的示例代码中，我没有看到大量的类和注释。所以请给我一个MCVE，我可以编译和运行它。特别是我需要查看课程DeliveryMethodsController 和DeliveryMethods，但是完整的MCVE 会好得多。我不想猜测您的代码可能是什么样子。如果您甚至不显示它，我怎么知道您要使用反射呢？

标签： spring-boot spring-aop spring-aspects

【解决方案1】：

很难让这个运行起来，因为缺少太多的类和注释，并且没有 MCVE 可供克隆。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，以使其更清楚一点，并将记录器的使用更改为仅在控制台上打印（您可以轻松地将其更改回来）。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运行起来。

  @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，它会打印：

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。

您的主要问题是反射使用：

您不仅需要设置名称，还需要设置getMethod(..) 中所有参数的类。
您还需要将实例提供给invoke(..)，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，因为我使用它删除了日志行，
旧值oldValue 和新值deliveryMethods 属于不同的类型，可能都是围绕已更改的实际值的不同类型的包装器对象。没有看到完整的代码，我不能说，这让我觉得有点奇怪。
