LaunchedURLClassLoader导致的内存溢出处理办法

问题：生产服务器，运行段时间后会导致微服务内存溢出，服务不可用，通过查看hprof文件，发现是由于类加载器导致的内存溢出

解决：

       <dependency>
            <groupId>se.jiderhamn.classloader-leak-prevention</groupId>
            <artifactId>classloader-leak-prevention-servlet3</artifactId>
            <version>2.7.0</version>
        </dependency>

        <dependency>
            <groupId>se.jiderhamn</groupId>
            <artifactId>classloader-leak-prevention</artifactId>
            <version>1.15.4</version>
        </dependency>

启动类注入

    @Bean
    public ServletListenerRegistrationBean servletListenerRegistrationBean(){
        ServletListenerRegistrationBean servletListenerRegistrationBean = new ServletListenerRegistrationBean();
        servletListenerRegistrationBean.setListener(new ClassLoaderLeakPreventor());
        return servletListenerRegistrationBean;
    }
