configurationproperties spring boot

In the use of spring boot, you can assign a value to a class by @configurationproperties and @Value two annotations, but two are used differently, and the following is an official description and an introduction to your own use. 1. According to their comparison, you can simply understand: 1 untie the set: @

24.7.4 @ConfigurationProperties ValidationSpring Boot'll attempt to validate external configuration by default using JSR-303 (if it's on the classpath).You can simply add JSR-303 javax.validation constraint annotations to your @ConfigurationProperties class:@ConfigurationProperties (prefix= "foo")publicclass fooproperties { @NotNull Private inetaddress re

Use mail to do the example. The configuration is placed in the Mail.properties file. The property must be named for the specification to bind successfully.Spring Boot uses some loose rules to bind attributes to the @ConfigurationProperties bean and supports a hierarchical structure (hierarchical structure).To start creating a @ConfigurationProperties bean:@

Sometimes there is such a situation, we want to the configuration file information, read and automatically encapsulated into the entity class, this way, we use in the code is easier and more convenient,At this point, we can use @configurationproperties, which can automatically encapsulate similar configuration information into entity classes.First in the configuration file, this information is such a dropConnection.username=Adminconnection.password=ky

External configuration Spring boot allows you to perform an externalized configuration, so you can run the same application code in different environments. You can use attribute files, YAML files, environment variables, and command-line parameters for external configuration. Attribute values can be injected directly into your beans using the @va

remark: A basic understanding of spring boot has been made through the previous chapters, but spring boot is just a box that encapsulates an integrated reference and needs to be combined with a specific project to really use it. The main record is to use spring

to annotate their main class. Since these annotations are used so frequently (especially if you follow these best practices), Spring boot provides a convenient @springbootapplication choice. The @springbootapplication annotation is equivalent to using @configuration, @EnableAutoConfiguration, and @componentscan with default properties.
