Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

介绍

Spring从2.0开始引入了一个新的机制用于扩展xml模式，我们就可以编写自定义的xml bean解析器然后集成到Spring IoC容器中。

xml扩展大概有以下几个步骤：

• 编写自定义类
• 编写xml schema来描述自定义元素
• 编写NamespaceHandler新样式.css的实现类
• 编写BeanDefinitionParser实现类
• 把以上组建注册到Spring
