一、新建一个maven 工程
二、在pom.xml文件中加入如下依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.bt.com.cn</groupId>
<artifactId>bt-springboot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>bt-springboot</name>
<description>bt-springboot</description>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
</parent>
<!-- Add typical dependencies for a web application -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<!-- Package as an executable jar -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
三、在src/main/resources下新建如下文件
内容分别
application-dev.properties
application-prd.properties
application-test.properties
appliction.properties
其中application.properties中spring.profiles.active=prd prd 为上面想要读文件的后一部分文件名
四、编写启动类
package com.batian;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
四、编写一个controller
package com.batian.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HttpController {
@Value("${httpUrl}")
private String httpUrl;
@RequestMapping("/getHttpUrl")
public String getHttpUrl(){
return httpUrl;
}
}
五、分别修改application.properties中spring.profiles.active=prd
1、当spring.profiles.active=prd 执行结果如下
2.当spring.profiles.active=test
3、当spring.profiles.active=dev
此时已实现不同环境下读取不同的配置文件
