添加maven配置

使用User类作为被审计的对象

@Entity
@Table(name = "user")
@Audited
@JsonIgnoreProperties(value = "hibernateLazyInitializer")
public class User {

  @Id
  @GeneratedValue
  private Long id;
  private String name;

  public Long getId() {
    return id;
  }

  public void setId(Long id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }
}

添加配置

spring.jpa.hibernate.ddl-auto=create
spring.jpa.properties.org.hibernate.envers.audit_strategy=org.hibernate.envers.strategy.internal.ValidityAuditStrategy
spring.jpa.properties.org.hibernate.envers.audit_strategy_validity_store_revend_timestamp=true
spring.h2.console.enabled=true
spring.h2.console.path=/h2
spring.datasource.url=jdbc:h2:mem:envers
spring.datasource.username=sa
spring.datasource.password=sa
spring.datasource.driverClassName=org.h2.Driver

创建相应的UserRepository

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
}

添加用于增删改的Controller

@Controller
public class UserController {
  @Autowired
  private UserRepository userRepository;
  private int counter;

  @ResponseBody
  @RequestMapping("/user/add")
  public Object add() {
    User user = new User();
    user.setName("name" + ++counter);
    userRepository.save(user);
    return user;
  }

  @ResponseBody
  @RequestMapping("/user/update/{id}")
  public Object update(@PathVariable Long id) {
    User user = userRepository.getOne(id);
    user.setName("name" + ++counter);
    userRepository.save(user);
    return user;
  }
  @ResponseBody
  @RequestMapping("/userhttps://img.qb5200.com/download-x/delete/{id}")
  public Object delete(@PathVariable Long id) {
    User user = userRepository.getOne(id);
    userRepository.delete(user);
    return user;
  }
}

添加启动类

@SpringBootApplication
public class SpringbootEnversApplication {
  public static void main(String[] args) {
    SpringApplication.run(SpringbootEnversApplication.class, args);
  }
}

运行程序后，访问http://localhost:8080/h2，输入密码sa，即可登陆数据库并查询数据

由于配置了spring.jpa.hibernate.ddl-auto=create，可以看到系统已经为我们生成了相关的数据表
