How to disable Hibernate validation in a Spring Boot project
提问by Erin Drummond
I have a spring boot project that has a CrudRepository, an Entity and a Controller. I am basically trying to persist an entity based on the data passed to the Controller.
我有一个 Spring Boot 项目，它有一个 CrudRepository、一个实体和一个控制器。我基本上是在尝试根据传递给控制器的数据来持久化一个实体。
To do this, I am using spring-boot-starter-jpa. My Entity is annotated with JSR-303 annotations, which are checked in the controller beforethe data gets passed to the CrudRepository for persistence.
为此，我正在使用spring-boot-starter-jpa. 我的实体使用 JSR-303 批注进行批注，在将数据传递到 CrudRepository 以进行持久化之前，这些批注会在控制器中进行检查。
Controller method:
控制器方法：
@RequestMapping(value = "users", method = { RequestMethod.POST })
public SuccessfulResponse<User> addUser(@Valid @RequestBody User user, BindingResult validation) {
if (validation.hasErrors()) {
throw new ValidationException(validation);
}
User saved = this.users.save(user);
return new SuccessfulResponse<User>(saved);
}
Entity:
实体：
@Entity /* JPA */
public class User {
@Id /* JPA */
@Column(name="email_address", nullable=false, length=255) /* JPA */
@UserUnique
private String emailAddress;
}
The cause of my issues is the UserUniqueannotation. Its validator looks like this:
我的问题的原因是UserUnique注释。它的验证器看起来像这样：
public class UserUniqueValidator implements ConstraintValidator<UserUnique, String> {
private UserRepository users;
@Autowired
public UserUniqueValidator(UserRepository users) {
this.users = users;
}
@Override
public void initialize(UserUnique annotation) {}
@Override
public boolean isValid(String value, ConstraintValidatorContext context) {
return users.findOne(value) == null;
}
}
What seems to be happening is, the validation is getting run twice. Once in the controller via the @Validannotation, and once when Hibernate tries to persist the object. However, when Hibernate tries to persist the object, it throws:
似乎正在发生的是，验证正在运行两次。一次通过@Valid注解进入控制器，一次当 Hibernate 尝试持久化对象时。但是，当 Hibernate 尝试持久化对象时，它会抛出：
javax.validation.ValidationException: HV000064: Unable to instantiate ConstraintValidator: class test.UserUniqueValidator`
This seems to be because its not spring-aware and cant inject the dependency into the constructor. So, what I want to do is disable Hibernate validation completely (as its redundant and already happening in the controller).
这似乎是因为它没有弹簧意识并且无法将依赖项注入构造函数。所以，我想要做的是完全禁用 Hibernate 验证（因为它是冗余的并且已经在控制器中发生）。
There seems to be a property called javax.persistence.validation.modewhich you can set to none. However, I cant for the life of me figure out where to set it in a code-based configuration.
似乎有一个名为的属性javax.persistence.validation.mode，您可以将其设置为none。但是，我一生都无法弄清楚在基于代码的配置中将它设置在哪里。
I realise there are questions like JSR-303 dependency injection and Hibernatebut these are all using xml config and manually configuring parts of the persistence layer.
我意识到有像JSR-303 依赖注入和 Hibernate 这样的问题，但这些都是使用 xml 配置和手动配置持久层的部分。
What I want to do is "post-configure" the required parts of the persistence layer that Spring Boot creates for me because if I define my own then I am no longer leveraging Spring Boot's auto configuration. Can anyone help me determine if 1) this is possible and 2) which parts do I need to configure and how?
我想要做的是“后配置”Spring Boot 为我创建的持久层的必需部分，因为如果我定义自己的，那么我就不再利用 Spring Boot 的自动配置。任何人都可以帮助我确定 1) 这是否可行以及 2) 我需要配置哪些部分以及如何配置？
Thanks!
谢谢！

As [M. Deinum] mentioned in a comment on my original post, the solution is to set:
作为 [M. Deinum] 在我原帖的评论中提到，解决方法是设置：
spring.jpa.properties.javax.persistence.validation.mode=none
In the application.propertiesfile.
在application.properties文件中。
Additionally, this behaviour is described here(its easy to miss because no example is provided).
此外，这里描述了这种行为（很容易错过，因为没有提供示例）。

@Erin Drummond's Answeris for database entity validation (individual records)
@Erin Drummond 的答案是用于数据库实体验证（单个记录）
But if someone ran into a problem with schema validationbelow property works well.
但是，如果有人遇到以下属性的模式验证问题，则效果很好。
# Hibernate ddl auto (create, create-drop, validate, update, none)
spring.jpa.hibernate.ddl-auto=none

Actually, in spring boot 2.x. it is:
