Spring Boot - Hibernate-Validator creates Errors when @PostMapping method is called

Time：07-05

This post is an off shoot of a recent question I had regarding POST requests in Spring Boot. While that issue was resolved, another issue came to light afterwards and my several hours of attempting to fix the issue myself has led nowhere. I'm quite certain that the issue is a small thing but I simply cannot find it anywhere.

Description

The issue is that the validation in my program is no longer working as intended. I'm using two seperate dependencies called spring-boot-starter-validation and hibernate-validator. I'm using the most recent version of hibernate-validator that I'm aware of.

All of my API mappings work as intended with the sole exception of the @PostMapping for creating new books. Whenever it's called, the Spring-Boot server returns a stack trace headed by java.lang.NoClassDefFoundError: org/springframework/validation/annotation/ValidationAnnotationUtils.

I've been looking into this particular line for a while now and the two most relevant pieces I could find were also on this website.

The information provided in this one was interesting but none of the suggestions helped. Here's everything they suggested that I tried.

  1. I did make sure that Hibernate-Validator was in the Java-Build-Path. I even made sure that it has the same version as Hibernate-Core. That being 5.6.8
  2. I updated Maven and even did a clean install.
  3. Restarted Eclipse.
  4. Tried setting Hibernate to version 6.

There may be an issue in the build path but I'm honestly not sure.

The other thread I looked at was here and its primary suggestion was to try the newest version of Hibernate-Validator which I mentioned earlier.

Code & Stacktrace

BookServiceController:

This is the only mapping in this particular controller class. I have no reason to believe that the class itself is flawed but the "createBook()" method is certainly part of the problem. As I said before, this is the only one of the several mappings that causes an issue though it should be noted that it's also the only @PostMapping on the entire server.

@RestController
@RequestMapping(path = "/books")
@CrossOrigin(origins = "http://localhost:8080")
public class BookServiceController {
    
    @Autowired BookService bookServiceImpl;
    
    @PostMapping(path = "/create")
    public ResponseEntity<Book> createBook(@Valid @RequestBody Book book) {
        try {
            Book newBook = bookServiceImpl.createBook(book);
            return new ResponseEntity<>(newBook, HttpStatus.CREATED);
        } catch (Exception e) {
            return new ResponseEntity<>(null, HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
}

Book Entity Class:

I don't think there's anything wrong with this class but I wanted to include it just in case I missed something.

@Entity
public class Book {
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    int bookID;
    
    @NotEmpty
    String title;
    String isbn;
    
    Integer series_part;
    Integer edition;
    int format;
    int pages;
    int authorID;
    int publisherID;
    int seriesID;
    int genreID;
    int languageID;
    int copyright;

    public Book() {
        
    }

Thoughts:

I'm really not sure with this one. I'm going to continue reading documentation on validation but I'm not sure what (if anything) I'll find. I'm still a novice at Spring Boot so JPA's sheer quantity of material can be overwhelming at times.

Thanks in advance for any help at all!

Update

I removed `hibernate-validator1 from the POM.xml and had Eclipse exclude it from the dependencies as well.

<dependency> 
            <groupId>org.springframework.boot</groupId> 
            <artifactId>spring-boot-starter-validation</artifactId> 
            <version>2.7.1</version>
            <exclusions>
                <exclusion>
                    <groupId>org.hibernate.validator</groupId>
                    <artifactId>hibernate-validator</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

This didn't solve the issue but it did get rid of the old error and replaced it with a new one. java.lang.ClassNotFoundException: org.springframework.validation.annotation.ValidationAnnotationUtils

I've included the full stack trace below and I'm going to continue researching this new code for possible causes.

CodePudding user response：

There's no need to have an explicit dependency to hibernate-validator. Starting from spring-boot 2.3 it should be sufficient to only have the validation-starter dependency:

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-validation -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
    <version>2.7.1</version>
</dependency>

Edit:

After some research, I think the problem is your dependency to spring-context as it seems to be outdated. Try updating it to a newer version. Also I'm not sure if it's even needed as an explicit dependency as it should come along with Spring Boot.
