我正在使用 Spring Boot 2.2.4.RELEASE，并且我有这个带有自动装配服务的自定义验证器。
@Component
public class CompanyRequiredValidator implements ConstraintValidator<CompanyRequired, Company> {
@Autowired
private CompanyService companyService;
@Override
public void initialize(CompanyRequired constraintAnnotation) {
}
@Override
public boolean isValid(Company company, ConstraintValidatorContext context) {
return company != null && companyService.findByCompanyName(company.getCompanyName()) != null;
}
}
我的验证配置。
@Configuration
public class ValidationConfig {
@Bean
public Validator validator() {
return new LocalValidatorFactoryBean();
}
@Bean
public MethodValidationPostProcessor methodValidationProstProcessor() {
MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
methodValidationPostProcessor.setValidator(validator());
return methodValidationPostProcessor;
}
}
无论我尝试了什么，自动装配字段都返回 null。我尝试过的事情：
