Javers Diff and Spring

Question

我有一个简单的Spring Boot 2.5.7 JPA应用程序，希望在一些实体之间进行审计差异

所以我的pom.xml包含这个依赖

<dependency>
<groupId>org.javers</groupId>
<artifactId>javers-spring-boot-starter-sql</artifactId>
<version>6.5.1</version>
</dependency>

我在应用中尝试了配置

javers:
algorithm: levenshtein_distance
dialect: POSTGRES

我创建了bean

@Bean
public Javers javers() {
return JaversBuilder.javers()
.withListCompareAlgorithm(ListCompareAlgorithm.LEVENSHTEIN_DISTANCE)
.build();
}

我还尝试添加了这个注释-JaversSpringDataAuditable

我的服务等级

@Service
@RequiredArgsConstructor
public class TestService {
private final Javers javers;
}

我只想知道这两个实体之间的区别https://javers.org/documentation/diff-configuration/

但我一直得到相同的错误

Answer 1

为什么要自己创建Javers bean？javers-spring-boot-starter-sql为您创建所有Javers的bean，并设置适当的SQL方言。尝试切换到由Javers的启动器创建的默认Javers Spring配置。
