SpringBoot2 配置prometheus浏览器访问404

背景:SpringBoot2的项目要配置 actuator + prometheus的健康检查，按照教程配置好之后再浏览器测试 http://localhost:port/prometheus 后404错误

项目pom文件添加;

<!--actuator-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
    <version>2.0.1.RELEASE</version>
</dependency>
<!--pometheus 监控-->
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
    <version>1.0.3</version>
</dependency>

springboot2的配置文件application.properties添加

management.endpoints.enabled-by-default=true
management.endpoints.web.exposure.include="*"
management.endpoints.web.base-path=/
management.endpoints.jmx.exposure.include="*"
management.endpoints.jmx.shutdown.enabled=false
management.endpoints.metrics.export.prometheus.enabled=true
management.endpoints.metrics.distribution.percentiles-histogram[http.server.requests]=true
management.endpoints.security.enabled=false
management.endpoint.health.show-details=always

然后启动项目发现 

 问题解决：

 

 *号在yaml文件中属于关健字，所以要加引号，但是再properties文件中就不能加引号

 

项目改成多模块应用后，prometheus又发生了404错误。经过排查，是根目录的pom.xml中prometheus配置的不对

错误的配置: 不能够配置到<dependencyManagement>标签中

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>
        <!--pometheus 监控-->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.0.3</version>
        </dependency>
    </dependencies>
</dependencyManagement>

正确的配置：

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>
        <!--pometheus 监控-->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.0.3</version>
        </dependency>
</dependencies>
