我已经构建了一个应用程序,它是一个Eureka服务器,服务注册表。 pom.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

<plugins>
<plugin>

<artifactId>spring-boot-maven-plugin</artifactId>

</build>
</project>
并且运行应用程序的主类如下:
package org.eureka.server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {
public static void main(String[] args) {
//ApplicationContext ctx = new SpringApplicationBuilder().bannerMode(Banner.Mode.CONSOLE).run(args);
SpringApplication.run(EurekaServiceApplication.class, args);
}
}
application.yml就是这样的:
server:
port: 8761
当它由clean spring-boot:run
命令运行时,会引发以下异常:
引起:java.lang.NoSuchMethodError:org.springframework.boot.builder.SpringApplicationBuilder.showBanner(Z)Lorg / springframework / boot / builder / SpringApplicationBuilder;在Org.springframework.cloud.bootstrap.BootstrapApp。 (BootstrapApplicationListener.java:1)位于org.springframework的org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172)org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165)。 org.springframework.boot.context.event.EventPublishingRunListener.environmentPrepared(EventPubl)中的org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:122)中的context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139) ishing.RringListener.java:74)org.springframework.boot.SpringApplicationRunListeners.environmentPrepared(SpringApplicationRunListeners.java:54)org.springframework.boot.SpringApplication.prepareEnvironment(SpringApplication.java:325)org.springframework.boot.SpringApplication.run (SpringApplication.java:296)org.springframework.boot.SpringApplication.run(SpringApplication.java:1118)org.springframework.boot.SpringApplication.run(SpringApplication.java:1107)org.eureka.server.EurekaServiceApplication。主(EurekaServiceApplication.java:16)
...还剩6个[INFO]
当我在pom.xml中删除eureka依赖项时,应用程序成功运行。 哪里错了?
你会像这样改变你的pom
