配置文件

设置Spring Boot 系统 yml 和自定义 yml文件

application.yml

spring:
  profiles:
    active: dev
    include: test  #或者 include: "test"
  application:
    name: test-yml-application

application-test.yml

test:
  msg: 这不就是配置文件的内容吗

基于抽象类的使用

常见的有两种方式

@Value

AbstractCp

public abstract class AbstractCp {

    @Value("${test.msg}")
    private String msg;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

}

Cp

@Component
public class Cp extends AbstractCp {

}

@ConfigurationProperties

AbstractCp

@EnableConfigurationProperties
@ConfigurationProperties("test")
public abstract class AbstractCp {

    private String msg;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

}

Cp

@Component
public class Cp extends AbstractCp {

}
