Question

我具有以下依赖性：

dependencies {
    compile('org.springframework.boot:spring-boot-starter')
    compile group: 'de.codecentric', name: 'spring-boot-admin-server-ui', version: '2.1.3'
    compile group: 'de.codecentric', name: 'spring-boot-admin-server', version: '2.1.3'
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

springBootVersion = '1.5.3.RELEASE'

当我尝试启动我的应用程序时：

@EnableAdminServer
@SpringBootApplication
public class MonitoringAdminApplication {

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

}

我看到错误：

我尝试将spring-boot-admin-server-ui和spring-boot-admin-server的版本降级为1.5.5，并在应用程序成功启动之后。

但是我想使用最新版本。我无法使用Spring Boot 2。

我该如何解决？

Answer 1

您不能也不应。与其他任何Spring Boot应用程序一样，Spring-boot-admin是在特定的Spring Boot版本上开发的。

spring-boot-admin 1.5.x基于Spring Boot 1.5.x
spring-boot-admin 2.0.x基于Spring Boot 2.0.x
spring-boot-admin 2.1.x基于Spring Boot 2.1.x

如果您不熟悉Spring Boot 1.5，则应该使用spring-boot-admin 1.5.7（1.5.x分支的最新版本）。

如何使用版本2的spring boot admin和版本1.5的spring boot？
