带有spring组件的javax.validator [英] javax.validator with spring component

问题描述

我在Spring中使用javax.validation.在测试中(常规)，我明确创建了验证器.

import javax.validation.Validation
import javax.validation.Validator
import javax.validation.ValidatorFactory

ValidatorFactory factory = Validation.buildDefaultValidatorFactory()
Validator validator = factory.getValidator()

when:
Set<ConstraintViolation<User>> constraints = validator.validate(entity)

我在Java中的验证器

public class EntityDynamicValidator implements ConstraintValidator<SomeConstraint, Entity> {

    private GroupService groupService;

    // This constructor is required, see the link bellow.
    public UserDynamicEnumValidator() {
    }

    public UserDynamicEnumValidator(final GroupService groupService) {
        this.groupService = groupService;
    }

    @Override
    public boolean isValid(final Entity entity, final ConstraintValidatorContext context) {
        Something something = groupService.findByValue(entity.getValue());
        // Validate all this stuff
    }
}

我需要将Spring 服务传递给验证器.

我有一个默认的构造函数，因为有一个问题 Validator的春季单元测试问题

解决方案

我也尝试解决此问题，但是测试对我来说是完全低级的单元测试，我希望避免过多的上下文.我什至无法使用您的方法.我这边的解决方案是将一个自定义ConstraintValidatorBean添加到嘲笑mvcvc中.该自定义实现可以获取验证器类Class对象的列表，因此，如果工厂尝试创建验证器，我将返回它的Mockito.mock版本，而不是真正的验证器版本. >

I use javax.validation with Spring. In my test (groovy) I explicitly create validator.

import javax.validation.Validation
import javax.validation.Validator
import javax.validation.ValidatorFactory

ValidatorFactory factory = Validation.buildDefaultValidatorFactory()
Validator validator = factory.getValidator()

when:
Set<ConstraintViolation<User>> constraints = validator.validate(entity)

My validator in java

public class EntityDynamicValidator implements ConstraintValidator<SomeConstraint, Entity> {

    private GroupService groupService;

    // This constructor is required, see the link bellow.
    public UserDynamicEnumValidator() {
    }

    public UserDynamicEnumValidator(final GroupService groupService) {
        this.groupService = groupService;
    }

    @Override
    public boolean isValid(final Entity entity, final ConstraintValidatorContext context) {
        Something something = groupService.findByValue(entity.getValue());
        // Validate all this stuff
    }
}

I need to pass a Spring service to the validator.

I have a default constructor because there is an issue Spring unit test issue with Validator

解决方案

I also tried to solve this, however the tests are fully low level unit tests on my side and I wanted to avoid too much of a context. I couldn't even use your approach. The solution my side was to add a custom ConstraintValidatorBean into the mockmvc. That custom implementation could get a list of validator class Class objects and so if the factory tried to create a validator, I returned a Mockito.mock version of it instead of the real one and I could also look that up for expectation settings.
