本文介绍了解决因JRE与JDK版本不匹配导致的问题的方法：使用较新版本的Java JRE运行Java代码，或者指定目标参数给Java编译器以生成与旧版Java兼容的代码。
To fix the actual problem you should try to either run the Java code with a newer version of Java JRE or specify the target parameter to the Java compiler to instruct the compiler to create code compatible with earlier Java versions.

网上很多资料都说是 JDK 版本问题，我没试过，最后把 project 级的 build.gradle 版本由 2.2.0 改为Android studio 对应的版本 2.3.2 ，gradle-wrapper.properties 也对应修改为 3.3-all.zip 版本。

Tomcat启动报错问题：unsupported major.minor version 52.0
Gawin的博客

首先，我们来分析几种可能的原因： 1、项目默认的JDK版本、项目编译的JDK版本、Tomcat的运行JDK版本不一致； 2、Tomcat版本过低，无法支持高版本jdk，导致web项目里包好的jar文件不能正确解析 但是究其根本，其实都是在启动过程中服务器JDK不能够正确执行被高版本JDK编译的项目，所以此时会爆出不能兼容的jdk版本错误，这里的52.0代指这jdk1.8版...

Java原生网络编程-BIO与NIO
照母山挖洋芋
11-24 760
摘要：本文对比了Java原生JDK中的BIO(阻塞I/O)和NIO(非阻塞I/O)网络编程模型。BIO采用"一连接一线程"模式，存在线程资源浪费和性能瓶颈问题，可通过线程池优化为伪异步I/O模型。NIO通过Selector、Channel和Buffer三大核心组件实现非阻塞通信，支持单线程管理多个通道。重点介绍了NIO的Reactor模式、事件类型(OP_READ/OP_WRITE等)及服务端/客户端的不同关注点，展示了NIO相比BIO在高并发场景下的优势。（149字）
spring全局懒加载(default-lazy-init)导致的afterPropertiesSet不执行问题
豆豆的博客
11-21 566
Spring配置default-lazy-init="true"会导致所有Bean延迟初始化，影响afterPropertiesSet方法的执行时机。解决方案包括：1)为关键Bean显式设置lazy-init="false"；2)使用@Lazy(false)注解；3)编程式强制初始化；4)使用DependsOn控制顺序。最佳实践建议分层配置策略，核心组件立即初始化，业务组件懒加载，并通过配置文件分离和环境区分优化配置。实际应用中，Web应用的请求处理相关Bean和批处
