Furthermore, if I use #NotNull annotation, then all exceptions are not thrown at all. Unfortunately I have to use #NotBlank, so I'd appreciate any help.
Following entity just have one field:
import javax.validation.constraints.*;
#NotBlank
private String name;

The only thing I can see in this stack trace is that you have a NullPointerException, which is thrown when commiting your transaction. Therefore a rollback is issued. You should check your parameters in the transaction.
org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:517) ~[spring-orm-4.3.14.RELEASE.jar:4.3.14.RELEASE] ... 85 common frames omitted Caused by: java.lang.NullPointerException: null

Try switch yourt #NotBlank import to org.hibernate.validator.constraints in your entity class or, if you can't switch import simply use:
#NotNull
#Size(min=1)
private String name;
It has the same effect as #NotBlank.

Is there a reason why using aliases in an SQL is returning an error?

I'm trying to run the following code in a Spring MVC Repository class to find the nearest Garda station (police station) to a latitude and longitude value input by a user on the client side. In the code below :latitude and :longitude represent the user input and the g.gardaStation_longitude and g.gardaStation_latitude represent the lat long values for the station stored in the database.
static final String HAVERSINE_PART = "(6371 * acos(cos(radians(:latitude)) * cos(radians(g.gardaStation_latitude)) * cos(radians(g.gardaStation_longitude) - radians(:longitude)) + sin(radians(:latitude)) * sin(radians(g.gardaStation_latitude))))";
#Query(value = "SELECT g FROM garda_station g ORDER BY "+HAVERSINE_PART+" DESC LIMIT 1", nativeQuery = true)
public GardaStation findByGardaStation_LatitudeAndGardaStation_Longitude(#Param("latitude") final double latitude, #Param("longitude") final double longitude);
However, the use of the 'g' in the query is resulting in an error. I've included aliases in many queries like this before and haven't seen such an error?

SELECT g FROM garda_station g is not proper syntax for native SQL, whereas it would be correct for JPQL/HQL. You're giving just a table alias where you're supposed to list columns, so it's either g.* or individual column names. In this case g.* since you're mapping the results to an entity.

In a SELECT clause, you need to list the fields you want to include in your result. Those would be columns in your garda_station table that you want included in the result. If you want to see all the fields, you could "SELECT * FROM garda_station".
Since you aliased your garda_station table as g, you could preface your columns with "g.", for example "SELECT g.* FROM garda_station".
Since g is not the name of a column, "SELECT g" will cause an error.

If I remove devtools dependency (build.gradle file) everything works as expected.
Any advice?
Thanks

I have resolved my issue adding the modules dependencies into spring-devtool.properties file, seems that I should have added the word "Modules" to this question.
Fix
Create file: resources/META-INF/spring-devtools.properties
File content: restart.include.common-code=/common-code-1.0.2.jar
Note: If the jar version will change you can use regex, something like --> /common-code-(.*).jar
Reference:
https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-customizing-classload
Greetings!!!!

A student is a Bean class in that class StudentDoc Bean class has Map data.
If this is a scenario that time you need to set the values using
student.doc.map
Try this, its work for me.

Spring + Hibernate #autowired is null in ConstraintValidator

I have search and found a lot of topic on this issue, but for whatever reason the solutions does not solve my problem.
I am running Spring boot 1.5.8 and Hibernate.
I have created a custom validation annotation to check if a email is unique compared to the database. The annotation is using a #autowired repository to query the database to check if the email already exist in the database. I keep getting an exception that the #autowired bean is null.
My theory is that the hibernate validator is being used instead of the UniqueEmailValidator class is therefore not wired properly. I am however clueless how to solve this issue.
#Documented
#Retention(RetentionPolicy.RUNTIME)
#Target(ElementType.FIELD)
#Constraint(validatedBy = UniqueEmailValidator.class)
public #interface UniqueEmail {
String message() default "{generic.error}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
#Component
public class UniqueEmailValidator implements ConstraintValidator<UniqueEmail, String> {
#Autowired
private UserRepository us;
#Override
public void initialize(UniqueEmail constraint) {
}
#Override
public boolean isValid(String val, ConstraintValidatorContext context) {
return !us.checkIfEmailExists(val);
}
}
I am calling this annotation in my entities like this:
public class{
#UniqueEmail
String email;
}
I am also calling #valid on the input of my rest methods.
#RestController
#RequestMapping(value = "/api", produces = MediaType.APPLICATION_JSON_VALUE)
public class UserController {
#RolesAllowed(Role.SUPERADMIN)
#RequestMapping(value = "/admin", method = RequestMethod.POST)
public ResponseEntity<User> createAdmin(#RequestBody #Valid UserWrapper uw) {
}
}

Please see below answers, I could reproduce this in my environment as well.
The validator being called twice, once the request is posted, another one is after the validation is done and entity gets persisted to DB, for the second time the autowired bean becomes null and throws NPE.
From the below answers, set validator property in entity manager along with other properties
<bean
id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceProvider">
<bean class="org.hibernate.ejb.HibernatePersistence" />
</property>
<property name="jpaPropertyMap">
<map>
<entry key="javax.persistence.validation.factory" value-ref="validator" />
</map>
</property>
</bean>
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
