【Properties】在Properties中配置List

my.properties

master.pool[0].id=poolId001
master.pool[0].endpoint=http://192.168.1.101:8080/v1
master.pool[1].id=poolId002
master.pool[1].endpoint=http://192.168.1.102:8080/v1
master.pool[2].id=poolId003
master.pool[2].endpoint=http://192.168.1.103:8080/v1

测试

package com.ssslinppp.controller;

import com.ssslinppp.commons.properties.PropertiesGet;
import com.ssslinppp.model.PropertiesList;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/prop")
public class PropController {

     @Autowired
    private PropertiesList propertiesList;

    @RequestMapping("/printProps")
    public String printProps(){
        System.out.println(propertiesList.toString());
        return propertiesList.toString();
    }

}

输出

PropertiesList{pool=[PoolConfiguration{id='poolId001', endpoint='http://192.168.1.101:8080/v1'}, PoolConfiguration{id='poolId002', endpoint='http://192.168.1.102:8080/v1'}, PoolConfiguration{id='poolId003', endpoint='http://192.168.1.103:8080/v1'}]}
