Field templateEngine in '....' required a bean of type 'org.thymeleaf.TemplateEngine' that could not be found

So i'm trying to generate a pdf file from a thymeleaf template but I get this error when running my app.
***************************
APPLICATION FAILED TO START
***************************
Description:
Field templateEngine in com.example.app.service.PdfService required a bean of type 'org.thymeleaf.TemplateEngine' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'org.thymeleaf.TemplateEngine' in your configuration.
Process finished with exit code 0
HERE IS HOW MY APPLICATION LOOKS LIKE. Everything looks correct and I don't know what i've done wrong
my configuration file :
#Configuration
public class ThymeleafConfig {
#Bean
public ClassLoaderTemplateResolver templateResolver() {
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setPrefix("templates/");
templateResolver.setTemplateMode("HTML5");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode("XHTML");
templateResolver.setCharacterEncoding("UTF-8");
templateResolver.setOrder(1);
return templateResolver;
}
}
my PdfService :
#Service
public class PdfService {
#Autowired
private TemplateEngine templateEngine;
public void createPDF() throws DocumentException, IOException {
Context context = new Context();
context.setVariable("name","developper.com");
String processHtml = templateEngine.process("helloworld",context);
OutputStream outputStream = new FileOutputStream("message.pdf");
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(processHtml);
renderer.layout();
renderer.createPDF(outputStream,false);
renderer.finishPDF();
outputStream.close();
}
}
my main app :
#Bean
CommandLineRunner run(PdfService pdfService) {
return args -> {
System.out.println("creating pdf...");
pdfService.createPDF();
System.out.println("pdf creation complete!");
};
}
EDIT : i managed to overcome the problem, but now i've been hit with another error :

In configuration class, you need to create template engine bean and set template resolver which you have created:
#Bean
public SpringTemplateEngine templateEngine() {
var templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
return templateEngine;
}
NOTE: TemplateEngine bean is not autoconfigured.

TemplateEngine is not autoconfigured, so you need to add to your configuration something like (remember to set the TemplateResolvers)
#Bean
public TemplateEngine templateEngine() {
return new TemplateEngine();
}
or alternatively, you can just inject it in the service via
final TemplateEngine templateEngine = new TemplateEngine();

After switching to SpringBoot from TomcatServerConf Request method 'POST' not supported

Initially, I started the project with IntelliJ Idea Tomcat Local Server configuration (everything worked), but decided to use Spring Boot Application. I added the main class, changed pom.xml (delete spring-context and add spring-boot-starter-parent, spring-boot, spring-boot-starter-tomcat, spring-boot-starter-web, spring-boot-autoconfigure), after that application runs , GET-Method works, but POST - not supported. Help me please!!! Thank you!

To implement the configure method in the main class you could do:
#SpringBootApplication
public class Main extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
#Override
protected SpringApplicationBuilder configure(
SpringApplicationBuilder builder) {
return builder.sources(Main.class);
}
}
I think these dependencies should be enough (assuming you are using Thymeleaf):

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.4.3</version>
<relativePath/>
</parent>

</dependency>

</dependency>
EDIT: Your ModelAttribute 'Category' might not be parsed successfully. Either the mapping fails, or maybe the validation? You might find out by adding an error handler and/or debugging the sessions.
Other ideas: Use #RestController instead of #Controller. Try to make the request mappings more explicit. Instead of on the class, put one on each method:
#RequestMapping(value = "/categories", produces = "application/json", method=RequestMethod.GET)
public String index(Model model) {
...
#RequestMapping(value = "/categories", produces = "application/json", method=RequestMethod.POST)
public String addCategory(#ModelAttribute("category") #Valid Category category,
BindingResult bindingResult, Model model) {
...

Thanks everyone! I found answer on my question. It was some problems with HiddenHttpMethodFilter. I just added this code in my Spring Config and extra dependencies was . It stared to work!!!
public FilterRegistrationBean<HiddenHttpMethodFilter> hiddenHttpMethodFilter() {
FilterRegistrationBean<HiddenHttpMethodFilter> filterRegistrationBean =
new FilterRegistrationBean<HiddenHttpMethodFilter>(new HiddenHttpMethodFilter());
filterRegistrationBean.setUrlPatterns(Collections.singletonList("/*"));
return filterRegistrationBean;
}

How can I pass object to thymeleaf template and access its attributes?

Is it possible to pass object let's say User (who contains 3 String attributes - name, password, detail) to thymeleaf template via context myContext.setVariable("user", myUser) and access it attributes from template like this <div th:text="${user.name}"/> ?
If so how can I do that ?
My object contains a lot of attributes and I am trying to avoid creating context with a lot of variables.
I am very new to thymeleaf so thank you for any help.

If you are using spring and thymeleaf then they should work for you like a charm. In the case it's as simple as:
private static final VAR_USER = "user"
#Autowired
private SpringTemplateEngine templateEngine;
...
public void method(User user,...) {
Map<String, Object> variables;
variables.put(VAR_USER, user);
context.setVariables(variables);
org.thymeleaf.context.Context context = new Context(locale);
String evaluated = templateEngine.process("myTemplate", context);
}
where myTemplate refers to resources/mails/myTemplate.html and it's content looks like:
<p th:text="#{email.userActivity.greeting}">Hello</p>
<p th:text="#{email.userActivity.text1}">Following user activity...</p>
<ul>
...
<li th:text="#{email.userActivity.phone(${user.phoneNumber}?: #{error.not.provided})}">Phone number:</li>
<li th:text="#{email.userActivity.membershipNumber(${user.membershipNumber}?: #{error.not.provided})}">Membership number:</li>
...
</ul>
<p th:text="#{email.userActivity.text2}">Thanks for taking care of this demand within the agreed period!</p>
<p th:text="#{email.userActivity.text3}">Regards</p>
and my User entity
public class User implements Serializable {
...
#Column(name = "membership_number")
private String membershipNumber;
#Column(name = "phone_number")
private String phoneNumber;
...
}
Then, my Thymeleaf configuration:

import org.apache.commons.lang3.CharEncoding;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

emailTemplateResolver.setPrefix("mails/");
emailTemplateResolver.setSuffix(".html");
emailTemplateResolver.setTemplateMode(TemplateMode.HTML);
emailTemplateResolver.setCharacterEncoding(CharEncoding.UTF_8);
emailTemplateResolver.setCheckExistence(true);
return emailTemplateResolver;
}

templateEngine = new MyTemplateEngine();
return templateEngine;
}
}

Root Cause

The templateResolver method needs to be fixed.
Try setting suffix
resolver.setSuffix(".html");
Try setting correct TemplateMode
resolver.setTemplateMode("HTML5");
I think this should solve the problem

Springfox Swagger2 - #ApiOperation not working

I use springfox-swagger2 for my Spring MVC REST API. Everything works good with swagger but my problem is I cannot add additional information to my swagger documentation.
Maven Dependency:
<!-- Swagger -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.2.2</version>
</dependency>
My Swagger config class:
#Configuration
#EnableWebMvc
#EnableSwagger2
#ComponentScan("path.to.controller.package")
public class SwaggerConfig {
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SPRING_WEB).apiInfo(apiInfo());
}
#Bean
public UiConfiguration uiConfig() {
return UiConfiguration.DEFAULT;
}
private ApiInfo apiInfo() {
ApiInfo apiInfo = new ApiInfo("Service API", "Simple REST Service", "0.0.1",
"mail#mail.com", "mail#mail.com", " ", " ");
return apiInfo;
}
}
My controller class:
#RestController
#RequestMapping("/persons")
public class PersonController {
Logger LOGGER = LoggerFactory.getLogger(PersonController.class);
#RequestMapping(value = "/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
#ApiOperation(value = "doStuff", response = Person.class)
#ApiImplicitParams({#ApiImplicitParam(name="Authorization", value="MY DESCRIPTION")})
public #ResponseBody Person getPerson(#PathVariable String id,
#RequestHeader(value = "Authorization") String authToken) throws Exception {
//do things and return
}
}
So, calling the swagger-ui the controller is shown, the method, everything except my additional infos defined in #ApiOperation and #ApiImplicitParams. Does anyone have an idea from where the problem can come from? The params are also not in the JSON file which is created from swagger.

Try to replace your customImplementation() method by:
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.build()
.apiInfo(apiInfo());
}
Build the project, and then your additional infos should appear.
