如何使用千分尺Springlegacy运行千分尺弹性？

Question

我对Spring很陌生，正在尝试将我的应用程序连接到麋鹿。该应用程序运行的是Spring boot 1.5.5，因此我使用的是微米遗产。我的pom看起来像这样：

		<dependency>
		  <groupId>io.micrometer</groupId>
		  <artifactId>micrometer-spring-legacy</artifactId>
		  <version>1.3.9</version>
		</dependency>
		<dependency>
		  <groupId>io.micrometer</groupId>
		  <artifactId>micrometer-registry-elastic</artifactId>
		  <version>1.5.1</version>
		</dependency>

每当我尝试启动我的应用程序时，我都会收到以下错误：

根本原因似乎是类io.micrometer.core.instrument.config.validate.Validated它似乎没有像它应该的那样出现在包中。对此有什么想法吗？

Answer 1

根本原因是千分尺内核的版本不匹配，这是由其他依赖关系造成的。我导入了以下内容

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-spring-legacy</artifactId>
  <version>1.3.9</version>
</dependency>
<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-elastic</artifactId>
  <version>1.5.1</version>
</dependency>

并遇到上述错误，因为这两个依赖项都包含一个版本的微米芯。在我的例子中，版本1.3.9。所需的类被添加到测微计。版本1.5.x的核心，因此解决方案是在版本1.1.x中显式定义依赖关系

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-spring-legacy</artifactId>
  <version>1.3.9</version>
</dependency>
<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-elastic</artifactId>
  <version>1.5.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.micrometer/micrometer-core -->
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-core</artifactId>
    <version>1.5.1</version>
</dependency>

无论如何，由于套接字超时，应用程序不会启动，但上面的错误已修复。:D迁移到Spring启动 2 可能是一个更快的解决方案。断续器
