How to get HttpServletRequest from spring proxy object - java

Into an interceptor class I want to get the HttpServletRequest object:
public class MyEndpointInterceptorAdapter extends EndpointInterceptorAdapter {
#Autowired
private HttpServletRequest httpServletRequest;
...
}
What I actually get is a proxy object of HttpServletRequest.
How I can get the original HttpServletRequest object out of this proxy spring object?
Update1:
Per request here is the stack trace:

Fund the answer, from the proxy object returned by spring on #Autowired, you dont have access to original HttpServletRequest object.
you can get the HttpServletRequest object, through a different path from: RequestContextHolder
HttpServletRequest httpServletRequest =
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
This gives you the original HttpServletRequest.

<option value="tamil">Tamil</option>
</select>
<label>Materialize Multiple Select</label>
</div>

output got in running html file without springboot:
Excepting the same with springboot, but ended up in error :/
Any kind of suggestion will be helpful!!
You should add multiple attribute to <select> tag, not <div>.
Please Change your html code to this :
<div class="input-field">
<select multiple>
<option value="english">English</option>
<option value="tamil">Tamil</option>
</select>
<label>Materialize Multiple Select</label>
</div>
didn't work for me, but i found a work around :-} added this section of code alone dynamically to the page using jquery so that eclipse can't throw error in html at runtime, anyhow thanks for the response :)

null value in column - Hibernate + Postgres

I am building a ridesharing app and essentially a driver (User) creates a Route which is composed of many Locations. A passenger (User) then requests a certain stop (Location) in a Route. When I try to persists a Location without a passenger (which comes with a different controller method for requesting a stop), I get a null value exception. Is there a way to ignore a null value for passenger upon a Location creation?
The following methods and annotations are generated from a class diagram.
Location.java
private User passenger;
#OneToOne(optional=false)
public User getPassenger() {
return this.passenger;
}
public void setPassenger(User passenger) {
this.passenger = passenger;
}
User.java
private Location request;
#OneToOne(mappedBy="passenger", optional=true)
public Location getRequest() {
return this.request;
}
public void setRequest(Location request) {
this.request = request;
}

After deploying in tomcat , getting exception : established connection was aborted by the software in your host machine

I found the same question here,
The solution discussed there was just to restart the eclipse/android studio, its fine in development machine. But in the production, the application is deployed in tomcat server 8 and getting the same issue after several request and response.
is something related database pooling or am I missing any configuration for database connection in spring boot?

Spring Boot REST ยท application.properties property causing NullPointerException

Continuing from my last question, that same property that I needed to add to application.properties to make ConstraintValidator works, spring.jpa.properties.javax.persistence.validation.group.pre-remove, is causing a NullPointerException when I try to delete an entity containing a list of the same type as a member. Simpler entities get deleted just fine. I even removed all validations, but it changes nothing.
Here's a project that's a non operational subset of the project I'm working on, here's the maven dependency tree, and here's the stack trace:

Please help me make it work.
Thanks in advance.
I found the solution (sort of). Actually, I didn't just included that property. It's the removal of the org.springframework.validation.Validators that caused the javax.validation validators to stop working. I found out that I needed to have a org.springframework.validation.Validator registered with the before|afterCreate|Save|LinkSave|Delete events and that I had to either call the complex entity's linked entity getter or change it's fetch = FetchType.LAZY to fetch = FetchType.EAGER.
My colleague gave me the suggestion when I mentioned that the NPE happens at a Hibernate code line that reads if ( persister.isExtraLazy() ) { (see top of stack trace).
Doesn't look like the right way of doing things, but it's working for now. If someone has something to add, I'll be grateful.

I am getting the following error :

I am trying to save in the following way :
Person x = new Person();
x.setFirstname("ABC");
x.setLastname("DEF");
x.setAge(30);
//Way 1 - failed
persistentService.save(x).publishOn(Schedulers.elastic()).subscribe(p -> log.info(p.getFirstname()), e -> log.error("failed", e));
//Way 2 - failed
persistentService.save(x).then().block();
//Way 3 - failed
persistentService.save(x).block();
There is no problem in connecting to cassandra. I am succesfully able to connect and the table schema is also getting creating on it's own through the spring data libraries.
Following is how my PersistentService looks like [which is autowired in the controller from where I am trying to persist the Person object] :
#Repository
public interface PersistentService extends ReactiveCassandraRepository<Person, String>{
}
I am using the following dependencies to achieve this :
spring-boot-starter-parent - 2.0.0.M3
spring - 5.0.0.RC3
spring-data-releasetrain - Kay-RC2
reactor-core - 3.1.0.M3
spring-boot-starter-data-cassandra - 2.0.0.M3
