I am following the book "Spring in Action, 5th Edition". Currently on Chapter 2 where validation is being applied to the forms. I have followed the exact same steps in the book but, but my forms don't recognize that there are any errors.
OrderFromController.java
Using Java Bean Validation API’s #Valid on the Order object being passed into the processOrder method
package com.example.tacocloud.contoller;
import com.example.tacocloud.dto.Order;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.Errors;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import lombok.extern.slf4j.Slf4j;
import javax.validation.Valid;
#Slf4j
#Controller
#RequestMapping("/orders")
public class OrderController {
#GetMapping("/current")
public String orderForm(Model model) {
model.addAttribute("order", new Order());
return "orderForm";
}
#PostMapping
public String processOrder(#Valid Order order, Errors errors) {
if(errors.hasErrors()){
log.info("Handling errors");
return "orderForm";
}
log.info("Order submitted: " + order);
return "redirect:/";
}
}
OrderObject.java
Object on which validation should be performed
package com.example.tacocloud.dto;
import lombok.Data;
import org.hibernate.validator.constraints.CreditCardNumber;
import javax.validation.constraints.Digits;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.Pattern;
#Data
public class Order {
#NotBlank(message = "Name is required!")
private String name;
#NotBlank(message="Street is required")
private String street;
#NotBlank(message="City is required")
private String city;
#NotBlank(message="State is required")
private String state;
#NotBlank(message="Zip code is required")
private String zip;
#CreditCardNumber(message = "Not a valid credit card number")
private String ccNumber;
#Pattern(regexp="^(0[1-9]|1[0-2])([\\/])([1-9][0-9])$",
message="Must be formatted MM/YY")
private String ccExpiration;
#Digits(integer=3, fraction=0, message="Invalid CVV")
private String ccCVV;

I'm trying to use the spring Email core package in my spring boot project.

javax.validation.constraints.Email annotation depends on Jakarta Bean Validation providers for validation.
You could try to add spring-boot-starter-validation dependency to your pom.xml. This dependency contains all the required dependencies (including jakarta and hibernate-validator which is a compliant validator for this)

This is the JSON value that i use with postman
{
"nic" : "656v",

"firstName" : "nn",
"lastName" : "",
"user": [{
"userName":"username1",
"email":"sample#gmail.com",
"password":"1234"

Please check your console output, e.g. if there is any exception in your service class. The code you provided does work and generates the output "hello".
I was working in a projet in intellij using: Spring-boot, maven and thymeleaf. At first I was running it as a Java application and it worked perfectly, but when I wanted to deploy it in a local Tomcat server or embedded Tomcat it can't resolve my html pages. I get the 404 not found message each time.
I tried to maven deploy in the tomcat manager, and them in the embedded tomcat in intellij and always the same problem.
I tried created a thymeleaf configuration file and always the same problem.

And this is my main Java class EpsApplication.java
package com.EPS.EPS;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class EpsApplication extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(EpsApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(EpsApplication.class, args);
}
}
Here is my project tree:
This is what I get
I am new to spring boot and trying to build a demo app. I would like to connect to a mysql DB using hibernate and fetch contents from a table. This is what my project structure looks like:
The class DemoApplication.java looks like this:
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
The HibernateTestController.java looks like this:
package com.example.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.example.repositories.PatchRepository;
#Controller
public class HibernateTestController {
#Autowired
PatchRepository patchRepository;
#RequestMapping(value={"/hibernateTest"})
public ModelAndView home() {
//List<Patch> patches = patchRepository.findAll();
return new ModelAndView("hibernateTest");
}
}
The PatchRepository.java looks like this:
package com.example.repositories;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import com.example.models.Patch;
#Repository
public interface PatchRepository extends CrudRepository<Patch, Long> {
List<Patch> findAll();
}
Now, whenever I start the application, I get an error saying:
*************************** APPLICATION FAILED TO START
Description:
Field patchRepository in
com.example.controllers.HibernateTestController required a bean of
type 'com.example.repositories.PatchRepository' that could not be
found.
Action:
Consider defining a bean of type
'com.example.repositories.PatchRepository' in your configuration.
I am not able to figure out why the Autowire for PatchRepository is not working. I think my project structure is right and that PatchRepository should automatically be detected by spring as a bean.
This is what the POM.xml looks like:

try using the repository scan in your DemoApplication class
#SpringBootApplication
#EnableJpaRepositories("com.example.repositories")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
lets try to add "#ComponentScan"
#SpringBootApplication
#ComponentScan("com.example")
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
Be sure that you have
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
and
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
into your pom.xml
Proper configs
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
And your Patch class is annotated with #Entity and have an Id Attribute annotated with #Id.
Everything should work.
I refactored my code as follows and things worked:
package com.example.repositories;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import com.example.models.Patch;
public interface PatchRepository extends CrudRepository<Patch, Long> {
List<Patch> findAll();
