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，该集合用于存储对象的旧值和更新后的值。我为此使用了@Before和@After的Spring AOP注释。
假设我必须编辑该对象，因此应将其以前的名称和更新的名称输入数据库。
这是我的审核报告类，
@Data
@Document(collection="auditReport")
public class AuditReport extends AuditEntity {
private String description;
private String old_value;
private String new_value;
}
此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;
}
这是我的方面课程，
@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（其参数与Id相同）来获取先前的记录。
但这给了我类似的错误，

但是该方法存在于我的控制器中。 谁能为我建议解决方案？或建议我在编辑对象时获取旧价值的另一种方法。 预先感谢。
答案 0 :(得分：1)
很难运行它，因为缺少太多的类和注释，并且没有MCVE可以克隆。另外，您的代码似乎以不同的方式两次检索了旧值，并将它们存储在不同的变量before和previous中。我删除了冗余，对变量进行了重命名和重组，以使其更清楚些，并更改了记录器的用法，以便仅在控制台上打印（您可以轻松地将其改回）。另外，您没有显示完整的内容，所以我不知道audiRepo的来源。我创建了许多虚拟类和注释以使所有内容正常运行。
@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，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
对于您来说，输出看起来有些不同，因为旧值和新值不只是虚拟对象。
您的主要问题是反射用法：
getMethod(..)中所有参数的类。invoke(..)提供实例，而不仅仅是参数。请注意
propertyName，因为我已使用它删除了日志行，oldValue和新值deliveryMethods具有不同的类型，可能是围绕更改的真实值的包装对象的不同类型。没有看到完整的代码我无法说，这让我有些奇怪。
