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'}]}
