I am building an application where Rest endpoints uses, boot bindings to send Neo4j Entitites to Neo4j Repo, and thats the pattern we repeated few times across jpa backed repositories. In current configuration;
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j</artifactId>
</dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
JPA repositories and neo4j repositories works ok, until i add;
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Erros i am facing are;
APPLICATION FAILED TO START
Description:
Constructor in org.springframework.data.neo4j.repository.config.Neo4jOgmEntityInstantiatorConfigurationBean required a single bean, but 2 were found:
- mvcConversionService: defined by method 'mvcConversionService' in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]
- integrationConversionService: defined in null
:: Spring Boot :: (v2.1.0.M2)
:: Java 8
Updating project dependencies to
<spring.boot.version>2.1.0.RELEASE</spring.boot.version>
<spring.cloud.version>2.1.0.RC3</spring.cloud.version>
has fixed the issue as per #meistermeier suggestion.

I have an application that created with Spring boot and Spring kafka libraries. Now I added jsonschema2pojo-core library to my pom file. After adding this jar file my test cases are failing with below error
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedKafka': Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: scala/runtime/java8/JFunction0$mcZ$sp

It's probably similar to this https://docs.spring.io/spring-kafka/docs/2.5.11.RELEASE/reference/html/#jacksonscala-incompatibility
with the library pulling in an incompatible scala library.
Yes, adding
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>2.12.11</version>
</dependency>
fixed it for me; but I can't guarantee that jsonschema2pojo will work with that version.
The scala folks are notorious for breaking API changes in patch releases.
everybody!
Could you give me advice about such an issue.
I have a simple test project in order to test using Microprofile config.
Field of my test class I test:
#Inject
#ConfigProperty(name = "injected.value")
private String injectedValue;
So this is the dependencies section of my pom:
<dependencies>
<!-- https://mvnrepository.com/artifact/org.eclipse.microprofile/microprofile -->
<dependency>
<groupId>org.eclipse.microprofile</groupId>
<artifactId>microprofile</artifactId>
<version>3.3</version>
<type>pom</type>
<scope>provided</scope>
</dependency>
</dependencies>
I build the war and then:
1. when i deploy war into the tomee 8.0.1-microprofile (tomee-maven-plugin with tomeeClassifier set up to microprofile) -> then all works OK.
2. BUT when i deploy war into the tomee 8.0.1-plus (tomee-maven-plugin with tomeeClassifier set up to plus) -> then i got exception:
org.apache.webbeans.exception.WebBeansDeploymentException: javax.enterprise.inject.UnsatisfiedResolutionException: Api type [java.lang.String] is not found with the qualifiers
Qualifiers: [#org.eclipse.microprofile.config.inject.ConfigProperty(name=injected.value, defaultValue=org.eclipse.microprofile.config.configproperty.unconfigureddvalue)]
for injection into Field Injection Point, field name : injectedValue, Bean Owner : ...
More over in case 1 (deploy to tomee 8.0.1-microprofile) when i change pom dependencies to:
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>8.0.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.microprofile.config</groupId>
<artifactId>microprofile-config-api</artifactId>
<version>1.4</version>
</dependency>
</dependencies>
i got the error:
org.apache.webbeans.exception.WebBeansDeploymentException: javax.enterprise.inject.UnsatisfiedResolutionException: Api type [java.lang.String] is not found with the qualifiers
Qualifiers: [#org.eclipse.microprofile.config.inject.ConfigProperty(name=injected.value, defaultValue=org.eclipse.microprofile.config.configproperty.unconfigureddvalue)]...
Please could anybody help me with this issue?
I need to use Microptofile in the prod and for now, I can't do it.
for the plus and plume version to work, you must include the following property in system.properties:
tomee.mp.scan = all
reference:
http://tomee-openejb.979440.n4.nabble.com/MicroProfile-Integration-in-Plus-and-Plume-td4686818i60.html
another way is using the tomee plugin and adding this property in pom.xml :
<systemVariables>
<tomee.mp.scan>all</tomee.mp.scan>
</systemVariables>
I wanna use Kafka client in Spring boot.
After reading the offical documentaion,
I added the maven dependency.
Then I tried to start Spring Boot. It throws
ClassNotFoundException.
This class is 'org.springframework.kafka.listener.RecordInterceptor '
Could anyone can solve this problem?
Version:
<spring.boot.version>2.2.1.RELEASE</spring.boot.version>
<spring.version>5.2.1.RELEASE</spring.version>
pom.xml:
<dependency>

<artifactId>spring-kafka</artifactId>
<version>${spring.boot.version}</version>

When using Spring Boot, you should let boot manage the version, for Boot 2.2.1, the proper version is 2.3.3.
Docs.
But, when using Boot, you can omit the version and Boot will automatically use the right version.

I'm trying to setup actuator metrics in Spring Boot 2 RESTful app, however - the list of supported metrics below does not include the
http.server.requests metric,
which is part of Spring MVC metrics, as described in https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready-metrics-spring-mvc
Below are the available metrics that are returned:
{
"names": [
"jvm.threads.states",
"jvm.memory.used",
"jvm.gc.memory.promoted",
"jvm.memory.max",
"jvm.gc.max.data.size",
"jvm.memory.committed",
"system.cpu.count",
"logback.events",
"tomcat.global.sent",
"jvm.buffer.memory.used",
"tomcat.sessions.created",
"jvm.threads.daemon",
"system.cpu.usage",
"jvm.gc.memory.allocated",
"tomcat.global.request.max",
"tomcat.global.request",
"tomcat.sessions.expired",
"jvm.threads.live",
"jvm.threads.peak",
"tomcat.global.received",
"process.uptime",
"tomcat.sessions.rejected",
"process.cpu.usage",
"tomcat.threads.config.max",
"jvm.classes.loaded",
"jvm.classes.unloaded",
"tomcat.global.error",
"tomcat.sessions.active.current",
"tomcat.sessions.alive.max",
"jvm.gc.live.data.size",
"tomcat.threads.current",
"jvm.gc.pause",
"jvm.buffer.count",
"jvm.buffer.total.capacity",
"tomcat.sessions.active.max",
"tomcat.threads.busy",
"process.start.time"
]
}
I have included following dependencies (among all):
...
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>
...
Is there a way to include the http.server.requests metric in my Spring Boot 2 application?
As it turned out - you need to do at least one http request to the application itself - excluding the management endpoints.
Just hitting any url within the app with a browser caused the http.server.requests to appear in the list of metrics.
I am using Spring boot version 2.2.0.M4. When I am adding dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<version>2.1.2.RELEASE</version>
</dependency>
while starting server it fails to start with below mentioned error
APPLICATION FAILED TO START
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.cloud.client.discovery.health.DiscoveryCompositeHealthIndicator.<init>(DiscoveryCompositeHealthIndicator.java:42)
The correct way of working with Spring Cloud projects versioning is using the dependencyManagement plugin and release trains versions rather than passing versions of separate artifacts manually.
You can get a correct pom generated automatically (with all the correct versions) at start.spring.io.
On the date that question was posted, a version of Spring Cloud supporting Spring Boot 2.2.x has not been released yet. The latest Spring Cloud release version available is Greenwich.SR2, that supports Spring Boot 2.1.6.RELEASE.
UPDATE: Spring Cloud Hoxton.M1 that supports Spring Boot 2.2.0.M4 was released on 3rd July 2019. You can now use it and also generate correct build files with this version from start.spring.io.
For the following dependency:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
The Following spring cloud version worked for me.
<properties>
<java.version>11</java.version>
<spring-cloud.version>Hoxton.SR4</spring-cloud.version>
