SpringBoot-04-配置文件(IEDA)

由 江枫思渺然 提交于 2020-01-31 22:36:56
4.1 SpringBoot配置文件类型和作用 SpringBoot是基于约定的，所以很多配置都有默认值，但如果想使用自己的配置替换默认配置的话，就可以使用 application.properties或者application.yml（application.yaml）进行配置。 SpringBoot默认会从Resources目录下加载application.properties或application.yml（application.yaml）文件 其中，application.properties文件是键值对类型的文件，之前一直在使用，所以此处不在对properties文件的格式 进行阐述。除了properties文件外，SpringBoot还可以使用yml文件进行配置，下面对yml文件进行讲解。 4.2application.yml配置文件 yml配置文件简介 YML文件格式是YAML (YAML Aint Markup Language)编写的文件格式，YAML是一种直观的能够被电脑识别的的数 据数据序列化格式，并且容易被人类阅读，容易和脚本语言交互的，可以被支持YAML库的不同的编程语言程序导 入，比如： C/C++, Ruby, Python, Java, Perl, C#, PHP等。YML文件是以数据为核心的，比传统的xml方式更加简 洁。

Conversion to Automatic Reference Counting (ARC): 'Use of undeclared identifier' errors

问题 In one of the very big projects I used auto-synthesized properties everywhere: //MyClass.h file: @interface MyClass : NSObject @property (nonatomic, retain) NSString *deviceName; @property (nonatomic, retain) NSString *deviceID; @end //MyClass.m file: #import "MyClass.h" @implementation ApplicationStatus // no @synthesize used at all. -(void)dealloc{ [_deviceName release]; // gives errors only while converting to ARC with LLVM 5.0 [_deviceID release]; [super dealloc]; } @end The code above

SpringBoot整合Druid多数据源含Sql和Web监控 新建数据库 导入依赖 修改配置文件 新建参数配置相关类 新建上下文环境相关类 新建主配置类 新建注解和AOP类 新建Sql和Web监控类 新建测试接口类 测试结果展示 新建数据库 新建三个数据库，准备测试。为了简单就随便意思一下吧，分别起名为springboot，springboot1，springboot2。然后在每个数据库里面都新建上一张名为person的表，并存入不同的数据。测试的时候就来查这些个person的列表。 导入依赖 其中 aop 多数据源要用到，druid用来实现监控，lombok用来减少代码，不用自己写getter、setter方法。 < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-aop </ artifactId > </ dependency > <!-- https://mvnrepository.com/artifact/com.alibaba/druid --> < dependency > < groupId > com.alibaba </ groupId > < artifactId > druid </ artifactId >

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 6 years ago . Many code samples in C# contain get and set code blocks. What is the purpose of them? I copy these blocks whey they appear in sample code, but have no idea what it is used for. Can someone please explain this to me? 回答1: Getters and setters enable you to combine a pair of functions into one

C# expression body with {get;} vs without [duplicate]

问题 This question already has answers here : What is the difference between getter-only auto properties and expression body properties? (2 answers) Closed 2 years ago . Since I don't know the term that applies to this, I am not sure what to search for existing comments on this. I recently wasted a ton of time with an expression body similar to: public SomeListViewModel SearchSomeModel => new ShowSomeViewModel{...}; When I tried to set values such as: SearchSomeModel.Property = 12345; It acted

Why is a property hiding Inherited function with same name?

由 给你一囗甜甜゛ 提交于 2020-01-30 06:05:46
问题 I have a class Foo with a function myName in it. Class bar Inherits from Foo and have a Property that is also called myName I figured this should be OK since: The property will compile to get_myName() (so there would not be a collision with Foo::myName(int,int) ) Foo::myName has arguments while, obviously, the property does not (again, no colision). Yet I still get the warning: 'Bar.myName' hides inherited member 'Foo.myName(int, int)'. Use the new keyword if hiding was intended. Example Code

问题 I'd like to do something like this: Private _myCollection As IList(Of T) Public Property MyProperty(Of T)() as IList(Of T) Get Return Me._myCollection End Get Set(ByVal value As String) Me._myCollection = value End Set End Property Basically, I want to have a collection of items that may be of any type. Then, I'll be able to do something like this: Dim myPropertyValue as <the type of some value> if (MyProperty.Contains(<some value>)) myPropertyValue = CType(MyProperty(<some value>), <the type
