Spring Boot and Hibernate: for org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor

I'm setting up a Spring Boot/Hibernate project for simple CRUD operation. For that I took help from several online tutorials and written the following code. But seems there is some version mismatch or similar dependencies in my POM.xml which I am unable to understand.
I getting a MAVEN build failure each time.

The specific error are as follows:
I am unable to understand how to correct the classpath of the application so that it contains a single, compatible version

How can i fix this ?

I encountered the same error recently, with spring boot 2.0.3.RELEASE.
When I added openfeign dependency first, without the version, I found that Maven was not pulling down the dependency (not sure why).
So I had to define the version explicitly for maven to actually pull it. With that, I also got the spring-cloud-starter-Netflix-ribbon transitively.
At this point, when I started up the server, I got the same error specified in the first post.
After adding spring-cloud-starter-Netflix-ribbon dependency with the version in the pom, the error got resolved. So I ended up adding these 2 dependencies:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>

Add ribbon dependency in your pom.xml.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-cloud-starter-ribbon</artifactId>
</dependency>
I also see some discrepancy in your BookFeignClient. #PathVariable should be used in place of #RequestParam.
#FeignClient(name="book-service")
public interface BookFeignClient {
#RequestMapping("book/view/{id}")
public Book viewBook(#PathVariable("id") String id);
}

#SpringBootApplication
#EnableFeignClients
#EnableDiscoveryClient
public class FeignClient {
public static void main(String[] args) {
SpringApplication.run(FeignClient.class, args);
}
}
change to
#SpringBootApplication
#EnableFeignClients
#EnableDiscoveryClient
public class FeignClientApplication {
public static void main(String[] args) {
SpringApplication.run(FeignClient.class, args);
}
}
it work now

I am working on a Hobby project, Here is my observation
I have followed this url issue on Feign, also from related question and answer from Abduqoidir
I have changed my spring boot project version
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.4.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
and changed the spring cloud version to
<spring-cloud.version>Hoxton.SR1</spring-cloud.version>

Try to add following code in your application class i.e. FeignClient :
#Bean
#LoadBalanced
RestTemplate restTemplate() {
return new RestTemplate();
}
and then check.
Plus I think your
#GetMapping("feign/view/{id}")
public Book viewBook(#PathVariable String id) { // pertaining to feign Controller
Should be replace with:
#RequestMapping("book/view/{id}")
public Book viewBook(#RequestParam("id") String id);

Would change the interface BookFeignClient, to version that is below, after this change Spring will not require balancing.
#FeignClient(name="book-service", url = "https://meu.dominio.com")
public interface BookFeignClient {
#RequestMapping("book/view/{id}")
public Book viewBook(#PathVariable("id") String id);
}

I think you should add the following anotation in your proxy:
#FeignClient(name="book-service")
#RibbonClient(name="external-service-name") // this is missing, the name of the external service registered in your naming server
public interface BookFeignClient {
...

Adding below dependency should solve the issue:
<!-- https://mvnrepository.com/artifact/io.github.openfeign/feign-slf4j -->
<dependency>
<groupId>io.github.openfeign</groupId>
<artifactId>feign-slf4j</artifactId>
<version>9.3.1</version>
</dependency>
Chose compatible version while adding. This dependency already present with-in the spring-cloud-openfeign-core but for some reason it does not get pulled.

Adding the below Maven dependency helped me to solve this issue-
<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form</artifactId>
<version>3.4.1</version>
</dependency>

Feign Client, Spring Boot Application, and rx/Observable Class Not Found Error

Some background: I have built two Spring Boot applications that are designed to be microservices. The first application (schedule provision) is a RESTful service that provides data for the other application (schedule checker). Therefore, there is a simple producer-consumer relationship between the two services.
After following the Spring tutorials for setting up microservice discovery using Eureka, I have a Eureka service registry that can be successfully stood up and the schedule provision and schedule checker services successfully register themselves with the Eureka service registry (validated by checking the landing page for the Eureka service).
I have now attempted to set-up microservice communication using Feign Client, i.e. I defined a Feign Client interface in the schedule checker service which should enable this service to contact the schedule provision service through Eureka end-point resolution, and consume data from the schedule provision service. However, after starting the Eureka discovery service and schedule provision services as Spring Boot applications, I keep receiving the following error when attempting to run the schedule checker service as a Spring boot application:
java.lang.ClassNotFoundException: rx.Observable
This is the root cause of an error chain that reads from top to bottom as:

As far as I can tell, the error appears to be being caused by a missing dependency on RxJava that results in the rx.Observable class not being available. However, after adding an RxJava dependency to the schedule checker service's pom.xml and running mvn clean install, the error detailed above persists. I'm unsure as to how to solve this issue since there doesn't appear to be any resources available online that address this problem in particular. The relevant classes/files from the two microservices I've built that should enable the behaviour I'm expecting (the schedule checker service consumes schedule provision service data through the REST endpoint defined in the schedule provision service):

After preparing this question, I resolved the issue with 2 co-workers help. The changes to be made are as follows:
RxJava is declared as a dependency by a number of Spring Boot dependencies so, the RxJava dependencies declared by these should be excluded to prevent conflicts.
A particular version of RxJava appears to be needed, I have included a dependency on the 1.0.12 version and this appears to be part of resolving the problem.
The project containing the services I'm building is a multi-module Maven project and as such, there is a parent pom.xml file. In this file, there is a dependency on org.springframework.cloud.spring-cloud-dependencies.pom.xml. The version of this dependency was set to Camden.SR3 but is now defined to be Dalston.RELEASE. Changing the version back to Camden.SR3 appears to cause the error defined in my original question.
There is some auto-configuration of beans performed by this spring-cloud-netflix class. This seems to cause the java.lang.ClassNotFoundException: rx.Observable issue mentioned. To resolve this, add the following annotation to the application class of the service that contains the Feign Client you want to set-up: #EnableAutoConfiguration(exclude = {RxJavaAutoConfiguration.class})
In summation, the changes to be made are as follows. With regard to the schedule checker service pom.xml (not the parent pom for the whole project), all other code remains as detailed in my original question:
Schedule Checker Parent

public class EmailArrivalMonitoringApplication {
public static void main(String args[]) {
SpringApplication.run(EmailArrivalMonitoringApplication.class, args);
}
}
Finally, it may be the case that: after running mvn clean install on your project (as I did), and starting the Eureka discovery service and services that should communicate (in my case, the schedule provision service and the schedule checker service), that the service containing the Feign Client throws an exception. I'm unsure as to why this occurs but, if you terminate the service and start it again, everything works well together.
I hope this helps, its taken me around 2 days to rectify this issue and I would urge the relevant persons at Spring Boot to update their documentation quickly and accordingly!

I inject a list of instances using yml:
myPrefix.locales:
-
code: "en"
language: "English"
-
code: "sv"
language: "Svenska"
#Data
#Component
public class Locale {
private String code;
private String language;
}
and this list is injected despite of error ( I log list values it in #PostConstruct method ), but then it fails with above exception.
spring boot version: 1.3.5.RELEASE
it works fine without sleuth.

I guess you've also asked this in Sleuth's repo - https://github.com/spring-cloud/spring-cloud-sleuth/issues/288

Spring: can't load properties on junit with PropertyPlaceholderConfigurer

Note: I've added the projects described above in a drop file service for easy reproduction and browsing -> http://dropcanvas.com/ujzw5
Only available for 3 days though.
Problem:
I have a program that works, called SomeBean. Running it I get the expected results and Spring wiring.
I'd like to make a separate test project which has a test class with Junit: acme-package2, to test my wiring on acme-package1. This works fine if SomeBean is injected with other beans, but not with properties from PropertyPlaceholderConfigurer.
My Question: I would like to know how to make SomeBeanWireTest from acme-package2 work.
I don't want to change acme-package1's SomeBean class, and I do want to continue using the springcontext.xml with classpath location on the PropertyPlaceholderConfigurer if possible.
Since my test is to verify the wiring of acme-package1, I don't want to have a different springcontext.xml on the test project because it defeats the purpose of testing the wiring of the original project.
My hope is that there is something I can do on SomeBeanWireTest that will test SomeBean's wiring without having to change SomeBean's code. Here's the code of the project:
SomeBean:
package com.acme.package1;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

private final static String CLASSPATH_METAINF_PREFIX = "classpath*:META-INF/";
#Autowired
private String injectedString;
public void setInjectedString(String injectedString) {
this.injectedString = injectedString;
}
public static void main(String[] args)
{
ConfigurableApplicationContext springContext = new ClassPathXmlApplicationContext(CLASSPATH_METAINF_PREFIX + "springcontext.xml");
SomeBean testBean = springContext.getBean(SomeBean.class);
testBean.printInjectedString();
springContext.close();
}
private void printInjectedString() {
System.out.println("Injected String: " + injectedString);
}
}

acme.injectedString=I am an injected String

Since springcontext.xml is explicitly setting the injectedString property, there's no reason to annotate the field with #Autowired. I'm not sure why it works in one context but not the other. Could be a difference in the behavior of ClassPathXmlApplicationContext (used in the main method) and GenericApplicationContext (used by the test class).
In any event, removing #Autowired will fix it. Another option would be annotating injectedString with #Value("${acme.injectedString}") and removing the <property name="injectedString" value="${acme.injectedString}" /> line from springcontext.xml.
