如何使用2版的spring boot admin和1.5版的spring boot？

Question

我有以下依赖项：

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 的版本降级到 1.5.5，然后应用程序成功启动。

但是我想用最新的版本。我无法使用 spring boot 2.

我该如何解决？

Answer 1

你不能也不应该。 Spring-boot-admin，就像任何其他 Spring 引导应用程序一样，是在特定的 Spring 引导版本上开发的。

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

如果您坚持使用 Spring Boot 1.5，那么您应该使用 spring-boot-admin 1.5.7（1.5.x 分支的最新版本） .
