spring-boot - 如何禁用 Spring boot 验证工厂

Question

在我的 Spring boot 应用程序中:

1. 有一个第三方 jar，其中包含旧版本的 javax.validation 库
2. 还有 Spring boot 默认 javax.validation 库 (1.1.0.Final) 附带 hibernate-validator (5.3.5.Final)

我的代码构建正确。但是，启动过程中失败并出现以下错误:

Caused by: java.lang.NoSuchMethodError: javax.validation.spi.ConfigurationState.getParameterNameProvider()Ljavax/validation/ParameterNameProvider;
    at org.hibernate.validator.internal.engine.ValidatorFactoryImpl.<init>(ValidatorFactoryImpl.java:146)

从日志中可以清楚地看出，没有找到 ConfigurationState.getParameterNameProvider() 方法，这是由于validation-api版本之间的冲突造成的。我知道 Hibernate-validator 需要新版本的validation-api(1.1.0)，但Spring以某种方式选择了第三方jar中存在的旧版本的validation-api类。

我无法从构建过程中删除旧版本的validation-api类，因为它们内置了我用于其他目的所需的第三方 jar。

我尝试了几个选项:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.validation.ValidationAutoConfiguration

和

application.properties 中的

spring.jpa.properties.javax.persistence.validation.mode=none 但它们都不起作用。

在 Spring boot 中是否有办法禁用 buildValidatorFactory 或 LocalValidatorFactoryBean 来避免此错误？

就我而言，以下解决方案有所帮助:

ValidatorFactoryBeanWithDisabledValidation.java

@Component
@Primary
@ConditionalOnProperty(prefix = "spring.custom.beans", name = "validator-factory-with-disabled-validation")
public class ValidatorFactoryBeanWithDisabledValidation extends OptionalValidatorFactoryBean {
    @Override
    public <T> Set<ConstraintViolation<T>> validate(final T object, final Class<?>... groups) {
        return Set.of();
    }

    @Override
    public <T> Set<ConstraintViolation<T>> validateProperty(final T object,
                                                            final String propertyName,
                                                            final Class<?>... groups) {
        return Set.of();
    }

    @Override
    public <T> Set<ConstraintViolation<T>> validateValue(final Class<T> beanType,
                                                         final String propertyName,
                                                         final Object value,
                                                         final Class<?>... groups) {
        return Set.of();
    }

    @Override
    public void validate(final Object target, final Errors errors) {
    }

    @Override
    public void validate(final Object target, final Errors errors, final Object... validationHints) {
    }

    @Override
    public void validateValue(final Class<?> targetType,
                              final String fieldName,
                              final Object value,
                              final Errors errors,
                              final Object... validationHints) {
    }
}

application.properties

spring.custom.beans.validator-factory-with-disabled-validation=true
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.validation.ValidationAutoConfiguration

我使用 spring-boot 2.1.2.RELEASE 版本，没有休眠。
