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());
