人面兽心, 行尸走肉, 所有人, 变坏
见风使舵, 投机倒把, 所有人, 起诉
在庭上,新闻里，所有人一文不值
吓死, 所有人愤怒了
我只是想说有谁在乎我们
我只是想说有谁在乎我们
打击我,憎恨我,你永远无法击垮我
利诱我, 威胁我, 你永远无法杀死我
我是犹太人, 你就要告我, 所有人都想整我,踢我
你颠倒是非黑白
我只是想说有谁在乎我们
我只是想说有谁在乎我们
告诉我我的生活变成了什么
我有个爱着我的妻子和两个孩子
我现在是个警察暴力的受害者了
我已厌倦作为厌恶的受害者
你在掠夺我的自豪
噢 究竟为了什么
我这是想把人间变为天堂...
放过我
人面兽心, 行尸走肉, 所有人, 变坏
人面兽心, 行尸走肉, 所有人, 变坏
见风使舵, 投机倒把, 所有人, 起诉
在庭上,新闻里，所有人一文不值
小人,告密,患难同胞,投入监狱
我只是想说有谁在乎我们
我只是想说有谁在乎我们
告诉我什么是我的权力
你对我视而不见我就不存在了吗？
你曾向我承诺自由
我已厌倦成为阴谋的受害者
他们把对我进行肆意的毁谤
我无法相信这就是养育我的那片土地
你知道我真的不想这么说
政府也不想看到这
如果罗斯福活着，他绝不会让这一切发生，不，不
人面兽心, 行尸走肉, 所有人, 变坏
见风使舵, 投机倒把, 所有人, 起诉
打击我,憎恨我,你永远无法击废我
袭击我,践踏我,你永远无法打垮我
我只是想说有谁在乎我们
我只是想说有谁在乎我们
生命中有些事是他们不想看到的
但如果马丁路德金活着的话
他绝不会允许它发生
人面兽心, 行尸走肉, 所有人, 变坏
见风使舵, 投机倒把, 所有人, 起诉
在庭上,新闻里，所有人一文不值
绊倒我,毁谤我,你指手画脚
我只是想说有谁在乎我们
我只是想说有谁在乎我们
我只是想说有谁在乎我们
我只是想说有谁在乎我们
我只是想说有谁在乎我们

【Android逆向工程】第8章：Frida 高级应用：函数追踪与 RPC 调用
w987333120的博客
12-01 204
本文介绍了Frida框架的核心功能与应用技巧，包括函数调用栈追踪、RPC机制、批量Hook、内存操作和脚本模块化等关键技术。重点讲解了Thread.backtrace()和DebugSymbol.fromAddress()的用法，提供Java和Native函数的调用栈追踪示例，并展示了调用栈过滤与分析方法。最后通过实战案例演示登录流程追踪和RPC调用，同时给出常见问题解决方案。这些技术可有效提升逆向分析效率，适用于移动应用安全测试场景。

主要是因为ClickHouse的DateTime类型精度只到秒级，不支持毫秒部分，而Java的LocalDateTime默认包含毫秒精度。（1） 服务提供者： 通过k8s Service 暴露出一组pod实例，并拥有一个稳定的DNS名称 ： user-service.default.svc.cluster.local。这个注解的正确使用对于保证对象比较的正确性非常重要，特别是在使用HashSet、HashMap等集合时！轻量级，中心化的调度方案，依赖JobRunLock，同一任务实例互斥。

78.56 MBopenjdk二进制下载地址Dockerfile中，source /etc/profile不能加载的原因为什么还需要选择使用他的原因：三 中，tomcat普通用户交互式启动tomcat#在 Docker 容器中，/etc/profile 文件不会在容器启动时自动执行，这是因为 Docker 容器通常不会启动交互式登录 shell，而是直接运行指定的命令。

在上述过程中，DispatcherServlet、HandlerMapping、HandlerAdapter和ViewResolver对象的工作是在框架内部执行的，开发人员只需要配置DispatcherServlet，完成Controller中的业务处理并在View中展示相应信息。DispatcherServlet是前端控制器，是整个流程控制的中心。（5） HandlerAdapter会调用并执行Handler（处理器），这里的处理器指的就是程序中编写的Controller类，也被称之为后端控制器。
