Explanation of a decorator class in python

邮差的信 提交于 2020-01-22 10:02:14
问题 While reading up about some python module I encountered this decorator class: # this decorator lets me use methods as both static and instance methods class omnimethod(object): def __init__(self, func): self.func = func def __get__(self, instance, owner): return functools.partial(self.func, instance) What I know about decorators, is that the can extend functionality (e.g. for a function). Could someone be so kind and explain to me why the class above is useful and how it exactly works ? It is

idea的配置文件------application.properties和application.yml

自作多情 提交于 2020-01-22 08:23:33
当application.yml 和 application.properties 两个文件同时存在的时候,application.properties的优先级是高于application.yml的,也就是说如果你的项目中存在 application.properties 文件时,application.yml文件是不能够发挥作用的。springboot更推荐使用application.yml代替application.properties,另外由于properties的配置文件含中文时读取会乱码,而在yml中不会,因此建议大家使用yml配置文件替换properties配置文件。 例子: 1 //application.yml 2 server: 3 port: 8080 4 spring: 5 application: 6 name: Admin Client 7 boot: 8 admin: 9 client: 10 url: http://localhost:9090 11 management: 12 endpoints: 13 web: 14 exposure: 15 include: '*' yml格式是大小写敏感的,使用缩进表示层级关系, 缩进时不允许使用Tab键,只允许使用空格, 缩进的空格数目不重要,只要相同层级的元素左侧对齐即可. (通常采用两个空格表示一个缩进

PropertiesFactoryBean PropertyPlaceholderConfigurer 区别

ぐ巨炮叔叔 提交于 2020-01-22 06:52:16
正如 stackoverflow 上说的,PropertiesFactoryBean 是PropertiesLoaderSupport 直接的实现类, 专门用来管理properties文件的工厂bean,默认是单例的, 而 PropertyPlaceholderConfigurer 是 解决 properties 文件占位符问题的,也实现了 PropertiesLoaderSupport 类。   在java 代码里,一般是使用@Value注解来引用 properties 文件的属性。 使用 PropertyPlaceholderConfigurer 时, @Value表达式的用法是 @Value(value="${properties key}") , 使用 PropertiesFactoryBean 时,我们还可以用@Value 读取 properties对象的值, @Value 用法 是 @Value(value="#{configProperties['properties key']}") <bean id="configProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="locations"> <list> <value

How to make a reference type property “readonly”

牧云@^-^@ 提交于 2020-01-20 17:32:30
问题 I have a class Bar with a private field containing the reference type Foo . I would like to expose Foo in a public property, but I do not want the consumers of the property to be able to alter Foo ... It should however be alterable internally by Bar , i.e. I can't make the field readonly . So what I would like is: private _Foo; public Foo { get { return readonly _Foo; } } ...which is of course not valid. I could just return a clone of Foo (assumming that it is IClonable ), but this is not
