此篇文章使用版本：2.2.2.RELEASE
热部署 源码
监控 源码

热部署

1）、加入依赖

<!--热部署-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
</dependency>

2）、修改了之后，使用Ctrl + F9使修改生效。也就是构建项目的快捷键。
在这里插入图片描述

3）、这里我添加了快捷键F5，使用Ctrl + F9 和 F5都可以构建。
设置编辑器的快捷键

# actuator 应用监控
        <!--actuator 应用监控-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

        ### actuator
        management.endpoint.metrics.enabled = true
        management.endpoint.prometheus.enabled = true
        management.endpoints.web.exposure.include = *
        management.metrics.export.prometheus.enabled = true
        management.metrics.tags.application = ${spring.application.name}
        management.health.redis.enabled = false
        management.health.ldap.enabled = false

# prometheus
可选择 => 例如 http://10.11.12.232:18003/actuator/prometheus
        <!--prometheus 监控采集-->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.8.2</version>
        </dependency>
        
        // fastjson 访问不了 prometheus 问题
        @Configuration
        public class WebMvcConfig implements WebMvcConfigurer {
        
            @Override
            public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
                FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter();
                FastJsonConfig fastJsonConfig = new FastJsonConfig();
                fastJsonConfig.setSerializerFeatures(SerializerFeature.QuoteFieldNames,
                        SerializerFeature.WriteEnumUsingToString,
                        SerializerFeature.WriteMapNullValue,
                        SerializerFeature.WriteDateUseDateFormat,
                        SerializerFeature.DisableCircularReferenceDetect);
                fastConverter.setFastJsonConfig(fastJsonConfig);
                converters.add(0, new StringHttpMessageConverter(StandardCharsets.UTF_8));
                converters.add(1, fastConverter);
            }
        }
