路由刷新

路由配置

ChoerodonRouteData choerodonRouteData = new ChoerodonRouteData();
choerodonRouteData.setName(environment.getProperty("hzero.service.current.name", "demo"));
choerodonRouteData.setPath(environment.getProperty("hzero.service.current.path", "/demo/**"));
choerodonRouteData.setServiceId(environment.getProperty("hzero.service.current.service-name", "demo"));

• choerodonRouteData.name: 路由名称, gatewayRoute的标识，对应gatewayRoute的id字段
• choerodonRouteData.path: 路由的路径;
• choerodonRouteData.serviceId: 通过实测、查看代码, 业务服务的这个配置无效; 虽然无效, 但是也不能不设置, 否则程序启动报错, bean实例化失败;

admin刷新路由的时候, 会把路由配置里的serviceId设置为serviceName: 
ParseRouteServiceImpl#executeRefreshRoute
data.setServiceId(serviceName);

如果开启了context-path, 路由配置需注意

//如果开启了context-path, 这里的路径必须和context-path保持一致
choerodonRouteData.setPath(environment.getProperty("hzero.service.current.path", "/demo-qxx/**"));
//这里设置为false
choerodonRouteData.setStripPrefix(false);

业务服务路由的name或path重复

新服务注册的路由如果和已有服务重复, 新服务会注册不上路由, 业务服务的日志里没有任何提示; admin服务里会info:

ParseRouteServiceImpl#executeRefreshRoute
LOGGER.info("route conflict, try to modify it on the interface, cause: {}", cause.toString());

路由被占用, 服务路由注册失败, swagger里会看不到服务, 普通开发者很难排查问题;
最终采用的解决办法: 服务启动时路由注册成功才能启动(hzero原版检查健康状态为up就能启动)

手动刷新路由报错: http transport failed, ExceptionResponse: For input string: "80,80"

dev环境正常, prod环境访问服务时报错error.permission.routeNotFound, 路由管理能看到路由, 手动刷新路由报错:

refresh service route error, serviceName=hw-platform, ex=fetch failed, instance: hw-platform, ex=http transport failed, ExceptionResponse: For input string: "80,80"

admin报错代码位置:

StringHttpTransporter#transport
ExceptionResponse response = objectMapper.readValue(body, ExceptionResponse.class);
if (response != null && response.getFailed()) {
    throw new RestClientException("http transport failed, ExceptionResponse: " + response.getMessage());
}

服务报错:

java.lang.NumberFormatException: For input string: "80,80"
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) ~[na:1.8.0_272]
    at java.lang.Integer.parseInt(Integer.java:580) ~[na:1.8.0_272]
    at java.lang.Integer.parseInt(Integer.java:615) ~[na:1.8.0_272]
    at ....swagger.controller.CustomController.componentsFrom(CustomController.java:145) ~[starter-core-2.0.0.RELEASE.jar!/:2.0.0.RELEASE]

代码位置:

...swagger.controller.CustomController#componentsFrom
String port = request.getHeader("X-Forwarded-Port");

if (hasText(port)) {
    builder.port(Integer.parseInt(port));
}

报错原因: X-Forwarded-Port=80,80;
修复方法: 加try..catch, 重置为-1;
