目录
一、使用@Profile
1.1、@Profile修饰类
开发环境
package com.example.demo.config; import com.example.demo.entity.AppData; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Profile; @Configuration @Profile("development") public class DevelopmentConfig { @Bean public AppData getAppData() { AppData appData = new AppData(); appData.setEnvironmentName("development"); return appData; } }
正式环境
package com.example.demo.config; import com.example.demo.entity.AppData; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Profile; @Configuration @Profile("production") public class ProductionConfig { @Bean public AppData getAppData() { AppData appData = new AppData(); appData.setEnvironmentName("production"); return appData; } }
1.2、@Profile修饰方法
package com.example.demo.config; import com.example.demo.entity.AppData; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Profile; @Configuration public class AppConfig { // 开发环境 @Bean("appConfigData") @Profile("development") public AppData getDevelopmentAppData() { AppData appData = new AppData(); appData.setEnvironmentName("app development"); return appData; } // 正式环境 @Bean("appConfigData") @Profile("production") public AppData getProductionAppData() { AppData appData = new AppData(); appData.setEnvironmentName("app production"); return appData; } }
1.3、@Profile修饰注解
1、定义注解
开发环境
package com.example.demo.annotation; import org.springframework.context.annotation.Profile; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Profile("development") public @interface Development { }
正式环境
package com.example.demo.annotation; import org.springframework.context.annotation.Profile; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Profile("production") public @interface Production { }
2、使用注解
package com.example.demo.config; import com.example.demo.annotation.Development; import com.example.demo.annotation.Production; import com.example.demo.entity.AppData; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class AppConfig { // 开发环境 @Bean("appConfigData") @Development public AppData getDevelopmentAppData() { AppData appData = new AppData(); appData.setEnvironmentName("app development"); return appData; } // 正式环境 @Bean("appConfigData") @Production public AppData getProductionAppData() { AppData appData = new AppData(); appData.setEnvironmentName("app production"); return appData; } }
二、激活@Profile
2.1、配置文件方式激活@Profile
application.properties
spring.profiles.active=production
application.yml
spring: profiles: active: production
2.2、命令行方式激活@Profile
java -jar target/demo-0.0.1-SNAPSHOT.jar --spring.profiles.active=production
三、多Profile资源文件
配置文件
# 公共配置 application.properties # development application-development.properties # production application-production.properties
application.properties
# 激活配置文件 spring.profiles.active=production
application-development.properties
server.port=8081
application-production.properties
server.port=8082
