1.自定义配置文件

######
    #服装
    etl.map[10]=服装
    etl.map[11]=春秋服
    etl.map[12]=半袖衬衣
    etl.map[13]=冬罩衣
    etl.map[14]=棉衣
    etl.map[15]=制式短裤
    etl.map[16]=针织背心
    #鞋
    etl.map[20]=鞋
    etl.map[21]=单鞋
    etl.map[22]=棉鞋
    #床上用品
    etl.map[30]=床上用品
    etl.map[31]=床单
    etl.map[32]=棉被
    etl.map[33]=棉褥
    etl.map[34]=被罩
    etl.map[35]=枕套
    etl.map[36]=枕套枕巾
    #配饰
    etl.map[40]=配饰
    etl.map[41]=皮带
    etl.map[42]=棉帽
    etl.map[44]=单帽
    #其他
    etl.map[90]=其他
    
    
    #list
    etl.list[0]=a
    etl.list[1]=b
    etl.list[2]=c

2.java config

package com.example.demo;
    
    import java.util.List;
    import java.util.Map;
    
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.PropertySource;
    
    import lombok.Data;
    /**
     * 读取配置文件
     * @author Bowin
     *
     */
    @Data
    @Configuration 
    @ConfigurationProperties(prefix = "etl",ignoreUnknownFields = false)
    @PropertySource(value ={"file:${user.dir}/config/custom.properties","file:${user.dir}/config/custom_prison.properties"}, ignoreResourceNotFound = true)
    public class PropertiesConfig {
    	private  Map<String,String> map;
    	
    	private List<String> list;
    	
    	private Map<String,String> prison;//监狱
    	
    }

3.测试

package com.example.demo;
    
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class DemoApplication  implements CommandLineRunner{
        @Autowired
    	private PropertiesConfig propertiesConfig;
      
       
    	public static void main(String[] args) {
    		SpringApplication.run(DemoApplication.class, args);
    	}
    
    	@Override
    	public void run(String... arg0) throws Exception {
    		Map<String, String> map = propertiesConfig.getMap();
    		System.out.println(map.size());
    	}
    }
