Validator尝试使用JSR-303(hibernate-validator)验证模型时,我在注入spring应用程序bean时遇到问题
我的主要配置类是:
@EnableAutoConfiguration
@EnableWebMvc // <---
@EnableJpaRepositories("com.example")
@EntityScan("com.example")
public class MainConfiguration {
根据javadocs:
/**
* Provide a custom {@link Validator} instead of the one created by default.
* The default implementation, assuming JSR-303 is on the classpath, is:
* {@link org.springframework.validation.beanvalidation.LocalValidatorFactoryBean}.
* Leave the return value as {@code null} to keep the default.
*/
Validator getValidator();
Hibernate-validator在类路径上.我正在尝试将其注入存储库:
@Repository
public class UserRepositoryImpl implements UserRepositoryCustom {
@Autowired
private Validator validator;
抛出异常:
No qualifying bean of type [javax.validation.Validator] found for dependency:
更新: …
下午好,
我在Bean验证器(JSR 303)中注入服务时遇到问题.我将执行验证,但我需要在我的数据库中验证此记录;
当我使用我的服务时,它会抛出NullPointerException;
例外:
