Poderiam enumerar as aulas para que seja possível acompanhar posteriormente na mesma ordem?

Bom quero compartilhar que fiz uma implementação do codigo da dio , num projeto que tinha começado para uma seleção de emprego mas que eu não tinha concluido, so que fiz algumas modificações, em vez de usar maven usei gradle e troquei o application.properties, por application.yml , e subi o banco por um arquivo sql , gostei do resultado final e gostaria de compartilhar aqui , ainda quero expandir esse projeto fazer outras modificações de repente pode ajudar alguém. https://github.com/claudioneves1981/controle-vendas

Boa tarde!
Estou realizando o curso Adicionando Segurança a uma API REST com Spring Security, e obtive o seguinte erro ao tentar adicionar o usuário:

Não sei como resolver, parece que é um erro no header do token...
Baixei o seu no github e apresentou o mesmo problema:


Poderia me ajudar a resolver??
Obrigada!!!!

Nessa parte do código está dando um erro no momento do extends, pois o adapter não se encontra mais ativo o seu import.

Existe algum motivo específico para criar métodos do repository? Não seria mais fácil utilizar os methods da JPA repository?

Só pra informar que é necessário fazer a modificação do nome da tabela user quando for integrar no db, senão dá erro por conflito com a palavra reservada do db. A modificação que eu fiz foi essa:

@entity
@table(name = "users") // modificando o nome da tabela para evitar conflito com a palavra reservada USER
public class User {...}

só colocar esse alias na table foi o suficiente.

Não estou conseguindo rodar aplicação da aula de Swagger:

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.plugin.core.support.AbstractTypeAwareSupport$BeansOfTypeTargetSource.<init>(AbstractTypeAwareSupport.java:135)

The following method did not exist:

    'void org.springframework.util.Assert.notNull(java.lang.Object)'

The calling method's class, org.springframework.plugin.core.support.AbstractTypeAwareSupport$BeansOfTypeTargetSource, was loaded from the following location:

    jar:file:/C:/Users/Sabbathhj/.m2/repository/org/springframework/plugin/spring-plugin-core/1.2.0.RELEASE/spring-plugin-core-1.2.0.RELEASE.jar!/org/springframework/plugin/core/support/AbstractTypeAwareSupport$BeansOfTypeTargetSource.class

The called method's class, org.springframework.util.Assert, is available from the following locations:

    jar:file:/C:/Users/Sabbathhj/.m2/repository/org/springframework/spring-core/6.1.8/spring-core-6.1.8.jar!/org/springframework/util/Assert.class

The called method's class hierarchy was loaded from the following locations:

    org.springframework.util.Assert: file:/C:/Users/Sabbathhj/.m2/repository/org/springframework/spring-core/6.1.8/spring-core-6.1.8.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.plugin.core.support.AbstractTypeAwareSupport$BeansOfTypeTargetSource and org.springframework.util.Assert


Process finished with exit code 1

Pesquisando, parece ser uma impompatibilidade entre Swagger e Springboot.
Estou com Java 17, e Springboot 3.3.0

Hello! I am teamed up with a large investor, looking for someone who can help build an app/platform around problem solving, that will allow multiple users to enter their point of view, allowing AI to reach a concencus. There are various complexities that make it quite a bit different and more robust than other AI "problem solving" platforms. I'm looking for someone who sees the vision enough to keep it on the budget friendly side, however aside from the project's funding I'm willing to be extremely generous with equity. Looking for someone who will hear my pitch, see the vision, and build something great together.

Erro no Terminal do Visual Studio Code.
