I am trying to implement a REST based MongoDB service through Spring, but I have run into some trouble. I cannot import a certain library.
I have this in my class:
package main;
import java.util.List;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
#RepositoryRestResource(collectionResourceRel = "people", path = "people")
public interface PersonRepository extends MongoRepository<Person, String> {
List<Person> findByLastName(#Param("name") String name);
}
But the import org.springframework.data.rest.core.annotation.RepositoryRestResource;
is not working for some reason and is giving me the error: The import org.springframework.data.rest cannot be resolved
This is my maven pom.xml:

Also, I am directly following this guide: http://spring.io/guides/gs/accessing-mongodb-data-rest/
How can this be resolved? Thanks
Edit your pom.xml.... and add these lines inside <dependencies></dependencies>...
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
<version>1.2.5.RELEASE</version>
</dependency>
I had a same problem on 1.3.6.RELEASE.
It said,
org.springframework.data.rest.core.annotation.RepositoryRestResource cannot be resolved to a type
So I set the version of spring-boot as 1.2.8.RELEAS, now I solve the problem.
My current spring-boot's pom.xml is below.
....
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.8.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
....
I had the same problem with this error message. In my case was the cause a refresh problem in the IDE (Intellij).
Deleting the line with the annotation (#RepositoryRestResource) and reinsert it helped a lot.
I also had tried to follow the same from https://spring.io/guides/gs/accessing-mongodb-data-rest/
For me, this issue got resolved after I added the version from https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-rest/2.3.0.RELEASE
to be more precise and clear, I added this in the pom.xml file to solve this issue. Maybe if you add the version it will start working!

I am working on microservices using springboot. While configuring the server, everything is going smoothly. I am working on springboot 2.4 with cloud version 2020.0.0.
enabled #EnableConfigServer on the main application class
added bootstrap dependency
created new git repo and property file
added configuration to the pom file
But when I work with a local git repo, my server responds and I can access the application through URL (eg. localhost:8888/client/default).
However, when I provide my remote git URL, the server does not respond to anything. My URL is correct and I have provided the username and passwords too.
There are no errors and nothing. Only 404 error page created by springboot.
What is the issue here? can anyone help?

But when I replace spring.cloud.config.server.git.url with local repo works fine. However, implementing a remote git address does not work. It doesn't give any errors too.
I found your git repository has main branch not master which is default branch for cloud config server.
To resolve this, you need to run client with property -Dspring.cloud.config.label=main or create master branch from main branch.

Tried this solution but no help
Log4j2 could not find a logging implementation with Sprint Boot
Add dependency to your pom
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-to-slf4j</artifactId>
<version>2.8.2</version>
</dependency>
This is because for my case the log4j is printing from Elasticsearch. I have implemented logback.xml for logging.
To overcome default log4j error messages, you can override with slf4j.
I have this problem in NetBeans 8.0 when I added the jar log4j-api-2.12.2.jar.
Netbeans print this message in the console.
"StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console..."
I resolved this problem when I added log4j-core-2.12.2.0001L.jar in my project.
I supposed in Spring, just most add the dependency log4j-core in maven.

I'm pretty new at Spring framework, and I try to start a project for practice.
But I have an error and I have no idea how to fix this.
I've created a new Spring project in IntelliJ Idea, with Spring Initializr option (In Intellij, not with start.spring.io ). I added only 2 dependedncies for start (Web and Thymeleaf), but it throws error for Thymeleaf dependency if i run it with
'mvn spring-boot:run' command.
My spring project is "empty" , I have no controllers, beans, jpa entites, etc.. but it i think it shound run in this way too. I just wanted to make sure if it works if I run it.
If I create a same project, without Thymeleaf dependency (only Web dependency), it starts correctly on localhost.
I'm using Java 9.0.4 and Apache Maven 3.5.3

I solved it with deleting the whole C\Users\user.m2 directory.
After then with 'mvn spring-boot:run' it started successfully on localhost.
But I've got one more question:
When I run it, at terminal there are a couple of Warning messages.
Spring application runs anyway, but is there something to do with these messages?
Warning messages during Spring application run.
I am learning Spring Boot. I have just created my first project using maven, Spring Boot, Spring Rest support and MongoDB. It compiles successfully, but it resolves all the dependencies, but do not compile the java classes at all.
After compilation, jar file is correctly created, it contain lib folder, metadata etc, but it do not contain project class file at all.
Hence when i run the project with mvn spring-boot:run, it throws an exception that class not found (Main method class for Spring boot initialization).
Please suggest, what I am doing wrong here, here is my maven configuration class:
<?xml version="1.0" encoding="UTF-8"?>

And here is the main initializer class:

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class BootInitializer {
public static void main(String[] args) {
SpringApplication.run(BootInitializer.class, args);
}
}
What I need to do, to ensure that maven is compiling the java classes and including them in the jar file.
Thanks.
I am learning Spring Boot.
Okay, good. Let's do one step at a time. Go to start.spring.io and generate a template project with whatever dependencies you want and whatever build tool (maven / gradle) you like. Build it and run it and see whether it is coming up or not. Then incrementally build on top of it.
I was trying to connect spring boot with jboss for a week... I read many topics on this forum and many of them are too old. I get error 404 every time when i want run server. Can you please help me to config my app with jboss properly?
UPDATE:
Thank you for help with error 404. I changed package to "war". But now when I run wildfly server Im getting error 403 (forbidden). I was looking how to fix it and still stay in the same place. It is so hard to get wildfly work with spring boot...

Follow this instructions: http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
You basically have to package your app as a WAR and implement SpringBootServletInitializer.
I found many mistakes in my project and now its working. I will write here answer for my app.
Physical naming was wrong. It should be: spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl. Or I could delete this line and it will be provided default from spring boot
I have Application.class in pl.seweryn.init package. I added #ComponentScan(pl.seweryn)
BookDaoImpl was not a spring component. Added line #Component
