with following code
@SpringBootApplication
@RestController
public class QuickPollApplication {
public static void main(String[] args) {
SpringApplication.run(QuickPollApplication.class, args);
}
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String testRest() {
return "rest tested";
}
and following is my pom.xml
UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-data-jpa org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-web-services org.hsqldb hsqldb runtime org.springframework.boot spring-boot-starter-test test org.springframework spring-web org.springframework.boot spring-boot-maven-plugin spring-snapshots Spring Snapshots https://repo.spring.io/snapshot true spring-milestones Spring Milestones https://repo.spring.io/milestone false spring-snapshots Spring Snapshots https://repo.spring.io/snapshot true spring-milestones Spring Milestones https://repo.spring.io/milestone falsePlease help me. I do not know how to solve this error
Solution 1:[1]
You have added
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
in your pom.xml.
Spring boot will try automatically create an entity factory for JPA, but you do not have defined anything regarding JPA models.
Try removing it in order to test what have you done so far.
Afterwards you can check a tutorial using spring-data-starter-jpa like this guy

I've fixed it by setting newer version of Hibernate.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<exclusions>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
</exclusion>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.10.Final</version>
</dependency>
You can find a fully working example here: https://github.com/zobarov/ptc-task-executor
Solution 3:[3]
You can also disable Spring Data JPA's repository support by excluding the following auto configuration class (e.g. in your @EnableAutoConfiguration
or @SpringBootApplication
annotation)
org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration
For example:
@EnableAutoConfiguration(exclude = JpaRepositoriesAutoConfiguration.class)

This worked for me.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<exclusions>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
</exclusion>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.2.10.Final</version>
</dependency>
