webmvc | Spring WebMVC / Jetty example | Model View Controller library

I'm getting this error because one of the fields in my domain class is a LocalDate. Stack trace below. Jackson is complaining about Java 8 date/time not being supported by default, but Spring Boot 2.5 comes with com.fasterxml.jackson.datatype:jackson-datatype-jsr310. How do I get Spring Batch to support my LocalDate field in my domain class?

If I change the field to be a java.util.Date it works perfectly.

Thanks!

I'm trying to get all information from Database inside a rest API in Sprint Boot, but I got the following error. I think Spring Boot doesn't recognize the Repository file I've created.

InstallationsRestController.java

I'm following the docs of spring framework and trying to realize it by code, but I'm stuck on AppConfig class. What dependency do I need to import AppConfig class? I've injected spring-beans, spring-web, spring-context, spring-webmvc already and my spring version is 5.2.5.RELEASE.

I googled "AppConfig cannot be resolved to a type" but couldn't get anything about it.

And this is the part of code from https://docs.spring.io/spring-framework/docs/current/reference/html/web.html#spring-web

I am trying to run a project in Java and came across the following issues:

I'm currently working on a microservices application for my internship using Consul for service discovery and feign clients for communicating between the services. When we started working on the existing project which already was built using microservices, we upgraded Spring boot to 2.4.3 & cloud to 2020.0.1, so that we could make use of Java 15 to use records instead of normal classes for dtos. The problem we have now is that, whenever we make a call to a composite service, that will try to retrieve data from multiple services (for example users and teams service), that we get the following stacktrace:

Firstly: Yes, i know there's lots of this question already asked but no one really helped me much.

Secondly:

-I've tried making a simple Auth with my username+password from MySQL credentials into the Postman but didn't worked

I've tried to remove the cookies from postman and that did not work.

Description:

link where i got the idea: youtube link for this crud web app

I'm trying to develop an simple CRUD web app with Spring Boot, Lombok, JPA and Hibernate, MySQL. Everytime i try to make a POST request into Postman it doesn't give me anything(401 Unathorized), as shown here:

It only gives me "401 Unauthorized".

Of course when i run the project it gives me the DB shown in MYSQL

Here's the project content:(That YML file has nothing in it)

Here's some code:

application.properties

I'm using Vaadin and Spring Boot to build webapp used as registration form.

I'm getting an issue when deploying the webapp inside a Tomcat (but never when lauching directly from Intellij IDE).

The Stacktrace is :

How should you setup a Spring entity that uses an Enum?

I have set up a spring-boot project and provided the code below so hopefully, someone can tell me the correct way this should be done.

I have a Spring entity setup

I am using Spring Boot to implement two web services, User and Book, and I am implementing the POST methods. When I send a POST request, i include the hard-coded JSON object in the HTTP Body: I am working at the same time on the two services, and while the creation of the "user" object works fine, Jackson throws an exception for the Book class. This situation occurres also with Postman, so it is not a problem of the JSON creation.

This is the Book class
