SpringBoot自定义配置以及IDEA配置提示

本篇文章将会讲解在springboot项目中如何实现自定义配置以及在IDEA或者Eclipse中实现配置项提示，就像spring的配置提示一样

想要做到这点其实非常简单

1.添加依赖

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

2.启用注解

在配置文件类上添加EnableConfigurationProperties注解，如下所示

@Configuration
@EnableConfigurationProperties
public class Config {

}

3.新增配置文件

以xxl配置为例新增如下配置文件

xxl:
  job:
    admin:
      addresses: http://127.0.0.1:8080/xxljob
    accessToken:
    executor:
      appname: my-app-name
      logpath: ./logs
      logretentiondays: 30

4.根据配置文件新建配置类

@Component
@Data
@ConfigurationProperties(prefix= "xxl.job")
public class XxlJobProperty {
    private String accessToken;
    private XxlJobAdminProperty admin;
    private XxlJobExecutor executor;
}

@Component
@Data
@ConfigurationProperties(prefix= "xxl.job.admin")
public class XxlJobAdminProperty {
    /**
     * xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
     */
    private String addresses;
}

@Data
@Component
@ConfigurationProperties(prefix= "xxl.job.executor")
public class XxlJobExecutor {
    private String appname;
    private String address;
    private String ip;
    private Integer port;
    private String logpath;
    private Integer logretentiondays;
}
