I have a Spring boot project which is built with Gradle.
I need to migrate it to Maven, which I thought would be easy (should be), but I've encountered an issue in the Zuul depedency, or to be exact: spring-cloud-starter-zuul.
When I run the Spring boot application with the annotation #EnableZuulProxy it produces the following error:
2017-03-30 00:02:57.521 WARN 11380 --- [ost-startStop-1] c.n.c.sources.URLConfigurationSource : No URLs will be polled as dynamic configuration sources.

2017-03-30 00:02:57.588 ERROR 11380 --- [ main] o.s.boot.SpringApplication : Application startup failed
The error only occurs on the Maven build, which narrow the problem to the pom.xml file vs build.gradle which does run.
After tinkering with the working build.gradle file, I've managed to produce the error when commenting out this part:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.3.RELEASE")
}
}
apply plugin: 'org.springframework.boot'
So the issue is I don't use the plugin in my maven file?

How can I make my maven project run? Or more specifically, what is the purpose of the spring boot gradle plugin?
Any help will be greatly appreciated!
You need to add dependency management in your pom.xml like below.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Camden.SR6</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I managed to get it working after a lot of trial and error.

I try to implement the spring-boot project with mongoDB.
The mongoDB isn't installed locally - I use docker image for this task.
So:
docker run -d --name mongodb -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=pass -p 27017:27017
docker image installed successfully and I able to enter into docker shell with
docker exec -it {conteinerId} bash
Now, I try to execute spring-boot application.
application.properties:
spring.data.mongodb.database=proxy_db
spring.data.mongodb.host=localhost
spring.data.mongodb.username=root
spring.data.mongodb.password=pass
spring.data.mongodb.port=27017

After launching I received warning:

And as result, error:
APPLICATION FAILED TO START
Description:
Failed to configure a DataSource: 'url' attribute is not specified and
no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
As I understand - the spring can't establish the connection with the database.
So, how to correctly manage MongoDB in the spring-boot + docker?
You are using the wrong property names, eg url, hence "Failed to configure a DataSource: 'url' attribute is not specified."
Try these:
spring.datasource.url = mongodb://localhost:27017/proxy_db
spring.datasource.username = root
spring.datasource.password = password
Optionally you may need this:
spring.datasource.driver-class-name = com.mongodb.Mongo
Also there appear to be missing/incorrect dependencies:
<!-- https://mvnrepository.com/artifact/org.mongodb/mongo-java-driver -->
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>

I have started creating a RESTful API using Spring Boot. I haven't touched Spring in 2 years. I am using Maven. I have the main class:

Any thoughts or directions I should move to? I have tried to synchronize dependencies and tried the latest and RELEASE packages in the pom. I have also deleted the whole m2 repo (twice).
Your problem is F:/Workspace/Uni/SoftwareEngineer/peopleapi/lib/javax.servlet.jar. Check why you have that JAR in your classpath (most likely it comes through some script or so). This seems to be an older version than the one you're referencing in your pom.xml

From the logs, it seems Spring is picking a different version for groupId org.springframework.data than the one provided with spring-data-jpa. If you could match the versions of spring-boot-starter-web and spring-data-jpa, it should work.
Quick fix being: Remove the version number for spring-data-jpa and it will by default take the latest version, which in your case is 2.1.10.RELEASE.

It seems like Jackson libraries not available for this boot project.
Either add Jackson libraries manually or add the following dependencies which will internally import Jackson libraries.

I solved the problem by excluding hibernate-validator dependency in pom.xml. It is working fine without any issues.
Resolved the issue by adding the below dependency for Jackson:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
Also make sure to remove classpath entries for Jackson

How should I make the package available to gradle?
You are using org.springframework.boot.context.web.SpringBootServletInitializer this is deprecated. Instead:
Use
org.springframework.boot.web.support.SpringBootServletInitializer
For SpringBoot 2.0
org.springframework.boot.web.servlet.support.SpringBootServletInitializer
It's probably an import issue in your source code - your Gradle build script uses Spring Boot 1.3.6.RELEASE in which SpringBootServletInitializer has the following fully qualified name:
org.springframework.boot.context.web.SpringBootServletInitializer
Your Maven pom.xml, however, uses Spring Boot 1.4.0.BUILD-SNAPSHOT, in which the package name was changed to:
org.springframework.boot.web.support.SpringBootServletInitializer
So if you go to your SampleJettyJspApplication and change the import to
import org.springframework.boot.context.web.SpringBootServletInitializer;
everything should be fine.
Alternatively, you could alter your Gradle build script to import 1.4.0.BUILD-SNAPSHOT, but that would require adding Spring's snapshot repository:
buildscript {
repositories {
maven.url "http://repo.spring.io/snapshot"
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.0.BUILD-SNAPSHOT")
}
}
You should use the same spring boot version 1.4.0.BUILD-SNAPSHOT as in maven. org.springframework.boot.web.support.SpringBootServletInitializer was introduced since 1.4.0 that's why gradle cannot find it.
org.springframework.boot.web.support.SpringBootServletInitializer
is deprecated.
use below instead:
org.springframework.boot.web.servlet.support.SpringBootServletInitializer
