To reference the properties or to configure in XML, there are two configuration methods for referencing a single properties file, and multiple properties files One, read a single properties file In the

• When configuring beans in a configuration file, it is sometimes necessary to mix the details of the system deployment in the bean's configuration (for example: file path, data source configuration information, etc.). And these deployment details actually need to be separated from the bean configuration The Spring provides a propertyplaceholderconfigurer Beanfa

The 1.Spring provides a propertyplaceholderconfigurer Beanfactory post processor that allows the user to put part of the bean's configurationMove to the properties file. You can load a property in a propertyplaceholderconfigurer dependency file by using a variable of ${var} in the bean configuration file.General

In the project if some parameters often need to be modified, or later may need to be modified, then we'd better put these parameters in the properties file, the source code read properties inside the configuration, so that only need to change the properties of the file can b

To understand the spring-boot of this technique, you should know Spring-boot's core profile application.properties, and of course you can customize the profile **.properties information through annotations. I. Reading the contents of the core profile information Application.properties A core profile is a application.properties or application.yml configuration

As we all know, spring can read the values in properties in a @value way, You only need to configure Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in the configuration fileBeanID= "Propertyconfigurer"class= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> Propertyname= "Location"> value>Classpath:config.propertiesvalue> Property>

At Spring boot learning 1 o'clock, you know that spring boot will read the configuration application.properties by default. So if we add a custom configuration item directly to the Application.properties, how to read it. Or do not want to put all the configuration in the application.properties, but instead of customizing a properties

The wildcard match in the Spring configuration file is comprehensive, but it is not possible to find the declaration of the element ' Context:property-placeholder ', which is basically the DTD parsing file that we did not introduce correctly when we introduced the namespace. Of course you have to import the appropriate package of
