Spring Boot - Issue with Spring Boot Starter Actuator

所以我正在创建一个新的 spring 引导项目并想尝试使用 spring-boot-starter-actuator。但是我在启动应用程序时遇到问题。

Pom 代码段:

      <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <!--<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

<spring-boot.version>2.2.0.RELEASE</spring-boot.version>

spring-boots 在我的类路径上:

启动应用程序时出错:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.boot.actuate.autoconfigure.metrics.orm.jpa.HibernateMetricsAutoConfiguration.bindEntityManagerFactoryToRegistry(HibernateMetricsAutoConfiguration.java:68)

The following method did not exist:

    io.micrometer.core.instrument.binder.jpa.HibernateMetrics.<init>(Lorg/hibernate/SessionFactory;Ljava/lang/String;Ljava/lang/Iterable;)V

The method's class, io.micrometer.core.instrument.binder.jpa.HibernateMetrics, is available from the following locations:

    jar:file:/C:/Users/rahul/.m2/repository/io/micrometer/micrometer-core/1.0.2/micrometer-core-1.0.2.jar!/io/micrometer/core/instrument/binder/jpa/HibernateMetrics.class

It was loaded from the following location:

    file:/C:/Users/rahul/.m2/repository/io/micrometer/micrometer-core/1.0.2/micrometer-core-1.0.2.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of io.micrometer.core.instrument.binder.jpa.HibernateMetrics

此时出现异常:

然而 HibernateMetrics 的构造函数只有一个,如下所示:

public HibernateMetrics(EntityManagerFactory entityManagerFactory, String entityManagerFactoryName, Iterable<Tag> tags) {
        this.tags = Tags.concat(tags, "entityManagerFactory", entityManagerFactoryName);
        this.stats = hasStatisticsEnabled(entityManagerFactory) ? getStatistics(entityManagerFactory) : null;
    }

从依赖分析器可以看出micrometer-core没有多个版本:

我也尝试过 spring-boot-starter-actuator version of 2.2.0.RELEASE,但它有同样的问题。

我不确定我在这里遗漏了什么,非常感谢任何帮助。

假设您将 spring-boot-actuator 应用程序连接到 JMX 控制台。 ("because it's not a web application")

我根据您的 pom 依赖项和 CommandLine运行ner 示例使用了 Spring Initializr。 Github 示例:https://github.com/thiagochagas/actuator-example

调整: 我删除了 "spring-boot-starter" 依赖项:

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter</artifactId>
     <exclusions>
         <exclusion>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-logging</artifactId>
         </exclusion>
     </exclusions>
</dependency>

我在 DemoApplication class 中使用了 Thread.sleep(30000L) 来简化示例。

安装并运行应用程序:

./mvnw clean install
java -jar target/demo-0.0.1-SNAPSHOT.jar

打开 jconsole:

$JAVA_HOME/bin/jconsole

虽然您的应用程序 运行 它应该在 jconsole 上。

Select 你的"demo-0.0.1-SNAPSHOT.jar" 分析一下:

如果显示此消息,select 选项 "Insecure Connection":
