SpringBoot中的Actuator

前序

Spring Boot有四大神器，分别是auto-configuration、starters、cli、actuator，本文主要讲actuator。actuator是spring boot提供的对应用系统的自省和监控的集成功能，可以对应用系统进行配置查看、相关功能统计等。

使用actuator

<dependency>

            org.springframework.boot

            spring-boot-starter-actuator

</dependency>

/autoconfig

{    "positiveMatches": {        "AuditAutoConfiguration.AuditEventRepositoryConfiguration": [

            {                "condition": "OnBeanCondition",

                "message": "@ConditionalOnMissingBean (types: org.springframework.boot.actuate.audit.AuditEventRepository; SearchStrategy: all) found no beans"

            }

        ]

    },

    "negativeMatches": {        "CacheStatisticsAutoConfiguration": [

            {                "condition": "OnBeanCondition",

                "message": "@ConditionalOnBean (types: org.springframework.cache.CacheManager; SearchStrategy: all) found no beans"

            }

        ]

    }

}

/configprops

{    "management.health.status.CONFIGURATION_PROPERTIES": {        "prefix": "management.health.status",

        "properties": {            "order": null

        }

    },

    "multipart.CONFIGURATION_PROPERTIES": {        "prefix": "multipart",

        "properties": {            "enabled": false,

            "maxRequestSize": "10Mb",

            "location": null,

            "fileSizeThreshold": "0",

            "maxFileSize": "1Mb"

        }

    },

    "environmentEndpoint": {        "prefix": "endpoints.env",

        "properties": {            "id": "env",

            "enabled": true,

            "sensitive": true

        }

    }

}

/beans

[

    {        "context": "application:8080",

        "parent": null,

        "beans": [

            {                "bean": "appMain",

                "scope": "singleton",

                "type": "com.xixicat.AppMain$$EnhancerBySpringCGLIB$$29382b14",

                "resource": "null",

                "dependencies": [ ]

            },

            {                "bean": "videoInfoMapper",

                "scope": "singleton",

                "type": "com.xixicat.dao.VideoInfoMapper",

                "resource": "file [/Users/xixicat/workspace/video-uber/target/classes/com/xixicat/dao/VideoInfoMapper.class]",

                "dependencies": [                    "sqlSessionFactory"

                ]
