Hibernate doesn't auto-create tables, I have set the properties and entity classes and the dependencies still the schema remains empty after I run the code. No error messages are shown.
Your strategy is:
spring.jpa.hibernate.ddl-auto = create-drop
This means that Hibernate creates the tables and after the program runs the tables are deleted. That's why you don't see any tables.
You have to use create (only creates tables) or update (also alters the tables):
spring.jpa.hibernate.ddl-auto = update
Then I don't see the JPA starter project in your pom.xml but you have Hibernate dependencies that are not necessary. Your pom.xml should look like:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

Validation Starter no longer included in web starters
As of #19550, Web and WebFlux starters do not depend on the validation starter by default anymore. If your application is using validation features, for example you find that javax.validation.* imports are not being resolved, you’ll need to add the starter yourself.
For Maven builds, you can do that with the following:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
For Gradle, you will need to add something like this:
dependencies {
...
implementation 'org.springframework.boot:spring-boot-starter-validation'
}
I'm facing a problem with Spring boot validation. Currently, I'm using Oracle JDK 11.0.12 and Spring boot 2.5.4 to build my project. I added constraints to validate the fields but it does not work. My code here:
import lombok.Data;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
#Data
public class LoginFormDTO implements Serializable {
private static final long serialVersionUID = 1L;
#NotBlank(message = "Login must not be blank")
private String login;
#NotNull(message = "Password must be provided")
private String password;
private boolean rememberMe = false;
}
#RestController
#RequestMapping("/api")
public class AccountResource {
// Logger and autowired components
#PostMapping("/authenticate")
#ResponseBody
public ResponseEntity<JWTToken> authorize(#Valid #RequestBody LoginFormDTO account) {
// Some code lines
return ResponseEntity.ok().body(new JWTToken(jwt));
}
}

I expect when I send POST request with body
{
"login": null, // or empty string "", or blank string " "
"password": "string",
"rememberMe": true
}
then the server should validate fields then throw exceptions or errors (because of null constraint violation) before executing code in my authorize(#Valid #RequestBody LoginFormDTO account) function, but it does not. So what's wrong with spring validation or am I missing something?
You can simplify your Controller. You have way too many annotations doing the same thing and even some weird stuff (you return ResponseEntity but then you tell Spring that the return of the method should be the Response Body).
This may not fix the #Valid issue but for sure will make it simpler:
#RestController
#RequestMapping("/api")
public class AccountResource {
// Logger and autowired components
#PostMapping("/authenticate")
#ResponseStatus(HttpStatus.OK)
public JWTToken authorize(#Valid #RequestBody LoginFormDTO account) {
// Some code lines
return new JWTToken(jwt);
}
}
#RestController is itself annotated with #Controller and #ResponseBody, which means that #RequestMapping methods assume #ResponseBody semantics by default, so you don't need to explicitly add it.
I found out that my SwaggerConfig class should use BeanValidatorPluginsConfiguration.class instead of SpringValidatorAdapter.class in #Import({}). Now my validator works normally. Thank João Dias for supporting me in figuring it out.
I am trying to create a simple JPA framework that performs simple CRUD operations like save employees, delete employees or get a simple employee.
When i am using the valid annotation
#PostMapping("/employees")
public Employee createEmployee(#Valid #RequestBody Employee emp)
return empdao.save(emp);
Its saying that Valid cannot be resolved to a type
I am using these starter dependencies listed below, I dont know if there is a conflict somewhere

Please provide a solution to this, or should i skip the Valid annotation all together,will it work without the valid annotation.
You need validation dependency, this should fix your problem :

The application runs fine but no tables are created.
User class that has to be stored in database:
#Entity
#Table(name = "user")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "userId", nullable = false, updatable = false)
private Long userId;
}
Why you are using org.hibernate.dialect.PostgreSQLDialect. you need to update dialect as per your database, update these two properties.
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
In your main class, try adding
#EntityScan(basePackages = {"packagename_where_entity_class_is_present"})
Hope it works!
OR
You can try reordering the packages i.e. for example, if your main class is in the package com.main, then let your entity class be in the package com.main.entity

This suspiciously looks like the regression in Spring Framework 4.3 RC1 that I've reported here. The issue is already fixed and the upcoming Spring Boot 1.4 M3 is going to include the fixed version.
The release Boot should be available in a couple of days. Until that has happened you could just manually upgrade to Spring Framework 4.3 RC2.
