SpringBoot实战第2章--自定义配置

注解

属性文件外置配置

• 要想使用属性文件外置配置，根据 Generating your own meta-data using the annotation processor 需要配置spring-boot-configuration-processor依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

• 配置properties文件

amazon.accountId=pengganyu

• PropertyConfig信息，需要添加@ConfigurationProperties注解

package com.idcos.automate.config;

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

@Component
@ConfigurationProperties(prefix = "amazon")
public class PropertyConfig {

    private String accountId;

    public String getAccountId() {
        return accountId;
    }

    public void setAccountId(String accountId) {
        this.accountId = accountId;
    }
}
