jdk1.8，这个没问题

这个是application的
@SpringBootApplication(exclude={WebMvcAutoConfiguration.class})
@EnableDiscoveryClient
@EnableFeignClients //注解是开启feign的扫描
@EnableJpaAuditing //加上这个,jpa才能在保存时自动生成时间
public class Application {

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

你期待的结果是什么？实际看到的错误信息又是什么？

有没有这块的行家，看一下

Answer 1

建议加上 spring boot 的版本号和 spring boot admin 的版本号。

java.lang.NoClassDefFoundError: org/springframework/boot/context/properties/bind/Binder

这块应该是 spring boot 2里面新增的扩展，我没记错的话，看看是不是你的spring boot 版本和 admin 不兼容。

Answer 2

在client的maven文件中添加两个包即可：

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
        </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency>
