作者接手一個(gè)SpringCloud項(xiàng)目時(shí)發(fā)現(xiàn)Eureka注冊(cè)的服務(wù)端口與實(shí)際Ribbon調(diào)用的實(shí)例端口不一致,通過(guò)查閱資料發(fā)現(xiàn)是Eureka讀取server.port不生效,通過(guò)在配置文件里添加nonSecurePort參數(shù)即可強(qiáng)制綁定端口

這段時(shí)間接手了一個(gè)公司的老項(xiàng)目，用的是SpringCloud
獲取到以后發(fā)現(xiàn)端口和配置的端口不一致
通過(guò)這個(gè)可以看到實(shí)例端口和實(shí)例id是不一致的
在Debug注冊(cè)Eureka的時(shí)候我發(fā)現(xiàn)
不知道因?yàn)槭裁丛驅(qū)е碌膃ureka讀取server.port不生效

這段時(shí)間接手了一個(gè)公司的老項(xiàng)目，用的是SpringCloud

在我用的時(shí)候突然發(fā)現(xiàn)有一個(gè)服務(wù)，注冊(cè)到Eureka后，界面顯示的端口和實(shí)際Ribbon調(diào)用的實(shí)例端口是不一致的，后來(lái)我自己寫(xiě)了個(gè)端口獲取了一下所有的實(shí)例信息，

方法如下：

@RestController
public class TestController {
    @Resource
    private DiscoveryClient discoveryClient;

    @RequestMapping("getServicesList")
    @ResponseBody
    public Object getServicesList() {
        List<List<ServiceInstance>> servicesList = new ArrayList<>();
        //獲取服務(wù)名稱
        List<String> serviceNames = discoveryClient.getServices();
        for (String serviceName : serviceNames) {
            //獲取服務(wù)中的實(shí)例列表
            List<ServiceInstance> serviceInstances = discoveryClient.getInstances(serviceName);
            servicesList.add(serviceInstances);
        }
        return servicesList;
    }
}

這個(gè)可以獲取當(dāng)前注冊(cè)到Eureka的所有實(shí)例信息。

獲取到以后發(fā)現(xiàn)端口和配置的端口不一致
