Spring-Boot:Profile简单示例

Posted 2020-08-29 告别的时代

//Resources目录下创建 application.properties
spring.profiles.active=prod

 

//Resources目录下创建 application-prod.properties
book.name=spring boot prod

 

package com.example.entity;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * Created by liz19 on 2017/1/26.
 */
@Component
@ConfigurationProperties(prefix = "book")
public class Book {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

 

package com.example;

import com.example.entity.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
@EnableConfigurationProperties({Book.class})
public class DemoApplication {

    @Autowired
    private Book book;

    @RequestMapping("/")
    public Book index(){

        return book;
    }

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

1. spring.profiles.active 指定使用的profile

2. Book为配置类， profile中的配置对Book类进行注入

3. @ConfigurationProperties(prefix = "book") 开启配置文件管理并用前缀为book的值进行注入
