原文描述
[quote]Configuring the behavior of Eclipse is straightforward - in the Preferences Dialog, the Debug pane under Java in the tree hierarchy, has the option titled "Suspend execution on uncaught exceptions", which can be unchecked.[/quote]

Windows->Preferences->Java->Debug
取消勾选 "Suspend execution on uncaught exceptions"，如图

Eclipse 在 Java 多线程编程中的应用
Java大师兄的博客
05-27 906
在当今的软件开发领域，多线程编程是提高程序性能和响应能力的关键技术。Java 作为一种广泛使用的编程语言，提供了强大的多线程支持。Eclipse 作为一款功能强大的集成开发环境（IDE），为 Java 多线程编程提供了丰富的工具和便利。本文的目的是详细介绍 Eclipse 在 Java 多线程编程中的各种应用，包括代码开发、调试、性能分析等方面。范围涵盖了从基本的多线程概念到实际项目中的应用，旨在帮助开发者更好地利用 Eclipse 进行 Java 多线程编程。
eclipse老是间歇性报ThreadPoolExecutor

今天下载了个eclipse的kapler版本，运行了个项目，用debug模式开启。 但是线程老是间歇性的停在 ThreadPoolExecutor$Worker.run()。上网搜了下，说是未捕捉异常导致的。可以在eclipse中修改下配置： 把"Suspend execution on uncaught exceptions" 把前面的勾去掉，然后就OK了

在MyEclipse中选择Window->Preference->Java->Debug， 然后将右侧的“Suspend execution on uncaught exceptions”的勾去掉即可
eclipse总是自动跳到ThreadPoolExecutor

出现这种状况是因为Eclipse默认开启挂起未捕获的异常(Suspend execution on uncaught exceptions)，只要关闭此项就可以了。 解决方法：在eclipse中选择Window->Preference->Java->Debug，将“Suspend execution on uncaught exceptions”的勾去掉即可。

Eclipse -> Preferences ->Java ->Debug “Suspend execution on uncaught exceptions” 勾去掉 就不会进debug了 注：Suspend execution on uncaught exceptions的意思是“当有未捕获的异常时暂停执行“

网页开发，在线%新版本旅游管理%系统，基于eclipse,html,css,jquery,servlet,jsp,mysql数据库

在帮助客户修改这个在线旅游管理系统Demo时，从需求分析到上线迭代，踩了不少坑也攒了些经验。用Eclipse搭框架，HTML+CSS 搞前端页面，jQuery优化交互，Servlet 和 JSP 做后端处理，再配上MySQL存数据，整套下来也算顺顺当当。开发时候关键是多测多改，用户体验这块不能偷懒。现在系统功能稳定，既能满足基础管理需求，也支持定制开发。
Eclipse为方法添加注释
chinalog的专栏
11-24 294
Eclipse中为方法添加文档注释的快捷键是 ‌Alt + Shift + J‌。将光标放置在方法名所在行或方法内部，使用此快捷键即可自动生成包含 @param、@return 等标签的文档注释模板。‌多行注释‌：Ctrl + Shift + / 添加注释，Ctrl + Shift + \ 取消注释。小建议‌：如果不确定快捷键，可以随时按 Ctrl + Shift + L5 调出完整的快捷键列表进行查阅。‌单行注释‌：Ctrl + /，可快速注释或取消注释当前行。

界面用HTML搭页面框架，再用CSS调样式，总在布局对齐上卡壳，最后靠jQuery写了些动态效果，页面才活起来。后端咱们用Servlet处理请求时，毕竟有点老了项目总遇到参数传递的坑，调试半天才发现是请求方式没对应上。连接MySQL数据库时，还踩过字段类型不匹配的雷，改了好几次表结构才通。整个过程虽然常加班改bug，但看着查询景点、预订订单这些功能跑通，特别有成就感。也明白做开发得细心，前后端衔接、数据交互每一步都不能马虎，不然一点小问题就可能让整个系统卡壳。
Eclipse 内置浏览器

Eclipse内置浏览器(Internal Web Browser)是提升开发效率的隐藏神器。通过快捷键Ctrl+Alt+B可快速打开，支持直接调试接口、查看Swagger文档、查询Javadoc、填写测试数据等10大实用场景。优化设置后，可将其设为开发专用导航页，绑定常用地址如本地Swagger接口。该工具能实现代码、接口和文档同屏操作，避免频繁切换浏览器，特别适合深色主题下的开发调试。通过简单配置，可让内置浏览器成为日常开发的效率加速器，大幅减少对外部浏览器的依赖。
基于数据驱动的 Koopman 算子的递归神经网络模型线性化，用于纳米定位系统的预测控制研究（Matlab代码实现）
最新发布
11-27
基于数据驱动的 Koopman 算子的递归神经网络模型线性化，用于纳米定位系统的预测控制研究（Matlab代码实现）内容概要：本文围绕“基于数据驱动的Koopman算子的递归神经网络模型线性化”展开，旨在研究纳米定位系统的预测控制问题，并提供完整的Matlab代码实现。文章结合数据驱动方法与Koopman算子理论，利用递归神经网络（RNN）对非线性系统进行建模与线性化处理，从而提升纳米级定位系统的精度与动态响应性能。该方法通过提取系统隐含动态特征，构建近似线性模型，便于后续模型预测控制（MPC）的设计与优化，适用于高精度自动化控制场景。文中还展示了相关实验验证与仿真结果，证明了该方法的有效性和先进性。; 适合人群：具备一定控制理论基础和Matlab编程能力，从事精密控制、智能制造、自动化或相关领域研究的研究生、科研人员及工程技术人员。; 使用场景及目标：①应用于纳米级精密定位系统（如原子力显微镜、半导体制造设备）中的高性能控制设计；②为非线性系统建模与线性化提供一种结合深度学习与现代控制理论的新思路；③帮助读者掌握Koopman算子、RNN建模与模型预测控制的综合应用。; 阅读建议：建议读者结合提供的Matlab代码逐段理解算法实现流程，重点关注数据预处理、RNN结构设计、Koopman观测矩阵构建及MPC控制器集成等关键环节，并可通过更换实际系统数据进行迁移验证，深化对方法泛化能力的理解。
