Failed to start bean 'eurekaAutoServiceRegistration'

Question

I have the following error starting ApplicationContext in my SpringBoot application:

org.springframework.context.ApplicationContextException: Failed to start bean 'eurekaAutoServiceRegistration'; nested exception is java.lang.NullPointerException

I have enabled Eureka Client with decorator @EnableEurekaClient in main class.

And I have configure .properties file with:

eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
eureka.instance.preferIpAddress=true

I use:

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        <version>1.4.3.RELEASE</version>
</dependency>

First of all, I have run Eureka Server in other spring boot project (it works properly).

Note: this is the main class:

package es.ual.acg.cos.abstractcomponents;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication(scanBasePackages={"es.ual.acg.cos.abstractcomponents", "es.ual.acg.cos.util"})
@EnableEurekaClient
public class AbstractcomponentsApplication {

    public static void main(String[] args) {
        SpringApplication.run(AbstractcomponentsApplication.class, args);
    }
}

Solution

I met the same problem,the reason for me is the version conflict.

my springboot version is 1.5.9.RELEASE,my project maven dependency is abort following:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.2.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpcore</artifactId>
        <version>4.2.1</version>
    </dependency>
<dependencies>
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Dalston.SR1</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

the reason is because I introduce the httpcomponents and its version is 4.2.1 ,but is difference with the eureka introduced httpcomponents version(the version is httpclient/4.5.3 and httpcore/4.4.6,u can use mvn dependency:tree to check it),i thought is the reason that cause Failed to start bean 'eurekaAutoServiceRegistration'.

and finally i changed the version of httpclient to 4.5.3 and httpcore to 4.4.6,then it works,I hope it helps you ^_^
