How to configure Java8TimeDialect manually in a Spring Boot application - spring

Question

Since I'm using Thymeleaf only for email template processing (not for view creation), I have the following exclusion in my application class (i.e. a class extending SpringBootServletInitializer):
#SpringBootApplication(exclude=org.springframework.boot.autoconfigure.thymeleaf.ThymeleafAutoConfiguration.class)
Absent Spring Boot's autoconfiguration, I need to configure the Java8TimeDialect class manually, so I've added the following bean to my ThymeleafConfig class:
#Bean
public Java8TimeDialect java8TimeDialect() {
return new Java8TimeDialect();
}
Nonetheless, I'm still getting the following exception:
Attempted to call method
format(java.time.LocalDateTime,java.lang.String) on null context
object
Clearly the temporals object isn't being added to the context. How can I resolve this?
I've included Thymeleaf in my POM file as follows:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>

Answer 1

Add pom.xml
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
then:
package com.users.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.thymeleaf.extras.java8time.dialect.Java8TimeDialect;
import nz.net.ultraq.thymeleaf.LayoutDialect;
#Configuration
public class Thymeleaf {
//TemplateEngine templateEngine = new TemplateEngine();
#Bean
public Java8TimeDialect java8TimeDialect() {
return new Java8TimeDialect();
}
#Bean
public LayoutDialect layoutDialect() {
return new LayoutDialect();
}
Finnally:
The time is: <strong th:text="${#temporals.format(now, 'dd/MMM/yyyy HH:mm')}">31/12/2015 15:00</strong>
