1.项目中引入依耐

<!-- 引入相关依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>
<!--lombok-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>

2.添加配置文件

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix = "file.upload")
@Data
public class FileUploadConfig {

    /** Maximum number of bytes per file */
    private String maxSize = "1024M";

    /** 不允许的文件后缀 */
    private String rejectSuffix;
}

　　

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import java.util.Map;


@Configuration
@ConfigurationProperties("map.test")
@Data
public class MapTestConfig {
    /** 测试Map类型数据的提示 */
    private Map<String, Object> data;

}

3.把项目 maven compile
