How to validate Mono when using Spring Reactive

阅读更多关于 How to validate Mono when using Spring Reactive

问题 We are evaluating Spring 5 for a project, and not sure how best to validate Mono parameters. Traditionally we had been using MethodValidationPostProcessor to validate our method parameters as below: @Validated @Service public class FooService @Validated(SignUpValidation.class) public void signup(@Valid UserCommand userCommand) { ... } We would then handle the exception in a ControllerAdvice or ErrorController , and pass a suitable 4xx response to the client. But when I change the parameter to

Is it the expected behaviour? Do I need to pass my own regex

If we define a class level validation annotation, such as one which compare fields and have a ConstraintValidator like this: public class ComparisonValidator implements ConstraintValidator<ValueMatches, Object> { private String[] fields; @Override public void initialize(final ValueMatches constraintAnnotation) { fields = constraintAnnotation.fields(); } @Override public boolean isValid(final Object value, final ConstraintValidatorContext context) { if (fields.length == 0) { return true; } final BeanWrapperImpl beanWrapper = new BeanWrapperImpl(value); final Object comparisonValue = beanWrapper

I know about @Valid annotation to instruct spring to validate for example a Controller argument according to JSR-303 in such this example: @GetMapping("/test") public TestDTO testDTO(@Valid TestDTO testDTO){ return testDTO; } But I would like to be able to configure Spring in some way to enable validation in all my controllers without specify explicitly the @Valid annotation. Is that possible in any way? Some Spring configuration? Making use of AOP?... I have finally came across with a working solution which may be not the optimal from the point of view of Spring configuration (as I said I'm
