Correct way to do an EntityManager query during Hibernate Validation

阅读更多关于 Correct way to do an EntityManager query during Hibernate Validation

I'm a bit of a Java EE/EJB noob, but from the docs and other posts I've gathered you cannot query the database using the same entitymanager/session during entity validation. In general, the lifecycle method of a portable application should not invoke EntityManager or Query operations, access other entity instances, or modify relationships within the same persistence context.[43] A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked. Translation please? This is pretty abstract...can it be explained in more concrete terms? It leads to more

I have an issue with bean autowiring inside a custom constraint validator. A constraint validator instance is not given using Spring's LocalValidatorFactoryBean. The JSR-303 provider is hibernate-validator 4.2.0.Final. Spring configuration excerpt :  <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" /> <bean class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor"/> Custom Constraint Validator: import javax.validation.ConstraintValidator; import javax.validation.ConstraintValidatorContext;

问题 This example is a bit contrived; I've simplified it to remove extraneous details and to focus on the problem I am having. I have a validator that looks like this: @Component public class UniqueUsernameValidator implements ConstraintValidator<UniqueUsername, String> { @Autowired UsernameService usernameService; @Override public void initialize(UniqueUsername uniqueUsername) { } @Override public boolean isValid(String s, ConstraintValidatorContext constraintValidatorContext) { return

I'm looking for a way to validate a java.lang.Double field in the Spring command bean for its maximum and minimum values (a value must lie between a given range of values) like, public final class WeightBean { @Max(groups={ValidationGroup.class}, value=Double.MAX_VALUE, message="some key or default message") @Min(groups={ValidationGroup.class}, value=1D, message="some key or default message") private Double txtWeight; //Getter and setter. public interface ValidationGroup{} } But both @Max and @Min cannot take a java.lang.Double value. Note that double and float are not supported due to

Using a custom ResourceBundle with Hibernate Validator

I'm trying to set up a custom message source for Hibernate Validator 4.1 through Spring 3.0. I've set up the necessary configuration:  <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"> <property name="validationMessageSource" ref="messageSource"/> </bean> The translations are served from my message source, but it seems that the replacement tokens in the messages themselves are looked up in the message source, i.e. for a: my.message=the property {prop} is invalid there are calls to look up 'prop' in the messageSource.

问题 Say I have a simple POJO like below annotated with Jackson 2.1 and Hibernate Validator 4.3.1 annotations: final public class Person { @JsonProperty("nm") @NotNull final public String name; public Person(String name) { this.name = name; } } And I send JSON like such to a web service: {"name": null} Hibernate when it reports the ConstraintViolation uses the class member identifier "name" instead of the JsonProperty annotation value. Does anyone know if it is possible to make the Hibernate
