Spring Cloud sleuth内存泄漏问题

Question

我正面临Spring云侦探的问题，因为它正在泄漏内存，因为我已经通过了我的应用程序的转储：

13.05mb（40.3%）的Java静态组织。springframework。云侦探。仪器异步。侦探ContextListener。隐藏物

Spring云版：霍克斯顿。SR8 Spring Boot版本：2.3.3。释放

请在下面找到heapdump报告：

请找到下面的代码回购，这是我在我的应用程序中使用的，同样在第一次运行时没有内存泄漏问题，但是在连续运行时，它显示了在heap转储报告中提到的内存泄漏问题

   package com.example.demo;

import java.util.Date;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

@SpringBootApplication
@EnableCaching
@EnableScheduling
public class DemoApplication {

    Logger log = LoggerFactory.getLogger(DemoApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @CacheEvict(cacheNames = { "config1", "config2" }, allEntries = true)
    @Scheduled(fixedDelay = 60000 * 5)
    public void cacheEvict() {
        log.info("Evicting all cache at: {}", new Date());
    }

}

Answer 1

你有一个完整的版本组合。为什么你说你在使用Hoxton和Boot 2.3如果你没有使用Hoxton，你在使用Greenwich和Boot 2.1

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Greenwich.SR4</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

请升级至Sleuth and Boot的最新版本。请转到“开始”复制此问题。Springio并生成一个新的、新鲜的项目。

更新：

在2020.0.3版本中，我改变了一个用来缓存bean工厂的类，现在它存储该类的散列。
