bootstrap和application dev
时间: 2023-10-06 22:09:59 浏览: 45
bootstrap.yml和application-dev.yml是Spring Boot项目中的两个配置文件。bootstrap.yml主要用于程序引导时执行,用来配置一些更加早期的配置信息,例如可以配置application.yml中使用到的参数。而application-dev.yml是针对开发环境的配置文件,用于配置开发环境下的相关属性。这两个配置文件在Spring Boot中的执行时机是在应用程序启动之前。

bootstrapProperties
Bootstrap properties are a set of configuration properties used during the application startup process in a software framework or platform like Spring Boot. These properties are typically defined in a configuration file, such as `application.properties` or `application.yaml`, and are used to configure various aspects of the application's behavior.
Bootstrap properties are specifically loaded and processed early in the application startup process, before other properties are loaded. They are usually responsible for configuring fundamental aspects of the application, such as logging, profiles, encryption, and data sources.
By setting bootstrap properties, developers can customize the behavior of the application without modifying the source code. These properties provide a convenient way to configure essential settings that are crucial for the application to start and function properly.
Here's an example of some common bootstrap properties in Spring Boot:
```
spring.application.name=MyApp
spring.profiles.active=dev
spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password=pass123
```
In this example, we set the application name, active profiles, and database connection details using bootstrap properties. These values will be picked up by the application during startup and used for configuration purposes.
It's important to note that bootstrap properties are specific to the framework or platform being used and may vary depending on the implementation.
spring cloud项目怎么确定引用application-dev.yml配置文件
在Spring Cloud项目中,可以通过`spring.profiles.active`属性来指定当前应用程序所处的环境。例如,将`spring.profiles.active`设置为`dev`,就表示当前应用程序处于开发环境。
在确定引用`application-dev.yml`配置文件时,可以通过以下方式来指定:
1. 在`bootstrap.yml`或`bootstrap.properties`配置文件中,可以通过`spring.cloud.config.name`和`spring.cloud.config.profile`属性来指定要加载的配置文件的名称和环境。例如,将`spring.cloud.config.name`设置为`application`,`spring.cloud.config.profile`设置为`dev`,就表示要加载`application-dev.yml`配置文件。
2. 在启动命令中,可以通过`--spring.profiles.active`选项来指定当前应用程序所处的环境。例如,使用以下命令启动应用程序:
```
java -jar myapp.jar --spring.profiles.active=dev
```
就表示当前应用程序处于开发环境,会自动加载`application-dev.yml`配置文件。
无论使用哪种方式,Spring Cloud都会根据指定的配置文件名和环境来加载相应的配置文件。如果找不到指定的配置文件,则会抛出异常。
