Phalcon vs Spring 用法对照表(持续更新)

FYI https://github.com/oscm/shell/blob/master/lang/php/pecl/phalcon.sh

You need to install with compiler, make tools.

 

#!/bin/sh

cd /usr/local/src/

git clone --depth=1 git://github.com/phalcon/cphalcon.git

cd cphalcon/build

./install

cat /srv/php/etc/conf.d/phalcon.ini EOF

extension=phalcon.so

 

1.2. Spring

You just only create a file as pom.xml, the maven will be fetch them.

9. Message Queue
Spring系列（十一）：@Profile 注解用法介绍 在Spring容器中如果存在同一类型的多个组件，可以使用@Profile注解标识实际要获取的是哪一个bean，这在不同的环境使用不同的变量的场景下非常有用。 最典型的例子：开发环境、测试环境、生产环境会配置不同的数据源，在尽量不修改代码的情况下，可以使用这个注解来动态指定要连接的数据源。
Spring系列（八）：Spring生命周期中BeanPostProcessor接口用法介绍 BeanPostProcessor接口通常被称为Bean的后置处理器，它是Spring中定义的接口，可以在Spring容器的创建过程中（主要在Bean初始化前后进行工作）回调BeanPostProcessor中定义的两个方法。
Spring系列（七）：@FactoryBean注解用法介绍 FactoryBean是实现了FactoryBean T 接口的Bean，可以该Bean的ID从BeanFactory中获取的实际上是FactoryBean中getObject()方法返回的实例对象，而并不是直接FactoryBean本身，想要获取FactoryBean对象本身，可以在id前面加一个 符号来获取
Spring系列（六）：@Conditional注解用法介绍 @Conditional是Spring4版本新提供的一种注解，它的作用是按照设定的条件进行判断，把满足判断条件的bean注册到Spring容器。
Spring系列（五）：@Lazy懒加载注解用法介绍 @Lazy 懒加载注解的概念 SpringIoC容器会在启动的时候实例化所有单实例 bean 。如果我们想要实现 Spring 在启动的时候延迟加载 bean，即在首次调用bean的时候再去执行初始化，就可以使用 @Lazy 注解来解决这个问题
Spring系列（四）：@Scope注解用法介绍 @Scope注解主要作用是调节Ioc容器中的作用域，在Spring IoC容器中主要有以下五种作用域：基本作用域：singleton（单例）、prototype(多例)；Web 作用域（reqeust、session、globalsession），自定义作用域。
