        stock.setStockCode("7000");

我有一个java Web应用程序，我想在数据库中为所有数据库更改创建审计日志，例如（列已更改，列中的值更改，用户ID，时间戳和其他一些字段）。我想创建一个通用服务，它具有为这些操作公开的方法，我可以从应用程序中的任何其他组件访问它们。据我所知，这可以通过hibernate envers或Spring AOP来完成。能否请您建议并向我提供一个例子，我可以利用它来进一步扩展它。

P.S。：我不想使用基于触发器的日志记录来审核数据库更改

假设这是我的实体股票;我正在通过hibernate执行一些简单的保存操作。假设，我有一个主要方法，我执行下面提到的操作

好吧，我不是Spring或Hibernate用户，所以我不知道你需要捕获什么。但如果它只是任何@Entity - 注释类的设置者，整个事情基本上会是这样的：

驱动程序应用程序：

package de.scrum_master.app;

import org.hibernate.Session;
import org.hibernate.Transaction;

public class Application {
    public static void main(String[] args) {
        System.out.println("Maven + Hibernate + MySQL");
//      Session session = HibernateUtil.getSessionFactory().openSession();
//      Transaction tx = session.beginTransaction();
        Stock stock = new Stock();
        stock.setStockCode("7000");
        stock.setStockName("z");
//      session.saveOrUpdate(stock);
    }
}

审核方面：

package de.scrum_master.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class DBAuditAspect {
    @Before("execution(public void set*(*)) && @target(javax.persistence.Entity) && args(setterArgument)")
    public void entitySetterExecution(Object setterArgument, JoinPoint thisJoinPoint) {
        System.out.println(thisJoinPoint + " - " + setterArgument);
    }
}

控制台输出：

Maven + Hibernate + MySQL
execution(void de.scrum_master.app.Stock.setStockCode(String)) - 7000
execution(void de.scrum_master.app.Stock.setStockName(String)) - z

文档第9. Aspect Oriented Programming with Spring章解释了如何设置和使用Spring AOP的一般性问题。

使用hibernate envers的通用java服务来审计用户在Web应用程序中的数据库中所做的更改
