首先没有安装组件的先安装springcloud alibaba(一) 组件安装,然后创建一个空的文件夹,然后用idea打开。

依然是在最外层的onlyone文件夹创建,不在parent上面创建,其他模块创建也是一样。
这个模块用来存放一些其他模块共用的实体类,共用方法等,因为本项目服务间的调用,用的dubbo插件,所以多了个service文件夹(共用的接口)。

标签的内容是parent模块的pom信息,其他模块也一样)

该模块用于服务数据提供。
这里parent
与common一样,并且将common模块引入,就可以使用共用方法了。
接着引入nacos包spring-cloud-starter-alibaba-nacos-discovery
,将application.yml配置内容放到nacos的包spring-cloud-starter-alibaba-nacos-config
,douuo包暴露提供方的数据方法spring-cloud-starter-dubbo
,bootstrap.yml 在cloud alibaba 2020.0.0 默认不在加载bootstrap 配置文件
,要用bootstrap 配置文件 需要手动添加spring-cloud-starter-bootstrap
依赖,不然启动项目会报错的,以及一些常规的插件包。

服务提供模块暴露的接口方法在 public 命名空间,不知道咋回事。
启动服务数据提供模块看看:
启动成功了!
该模块用于服务数据调用。
pom 文件和上面的provider差不多,多了个sentinel
的包spring-cloud-starter-alibaba-sentinel
,用于接口的限流以及sentinel配置持久化到nacos的包sentinel-datasource-nacos
。

注意:这里需要注意的就是 sentinel 持久化到 nacos 的配置
注意:这里的 命名空间 组名称,之前的yaml 换成 Json
配置内容:
[
{
"resource": "infof",
"limitApp": "default",
"grade": 1,
"count": 1,
"strategy": 0,
"controlBehavior": 0,
"clusterMode": false
},
{
"resource": "infoe",
"limitApp": "default",
"grade": 1,
"count": 1,
"strategy": 0,
"controlBehavior": 0,
"clusterMode": false
}
]
里面的参数对应说明请查看sentinel 官网说明
对应下图的表单里面的字段
启动项目看看
@DubboService
,目前最新的是@DubboService,老版本的是@Service
注意导包。@SentinelResource
value
:对应nacos里面sentinel json配置的"resource": "infof"
。blockHandlerClass
:发生流控时的回调方法。blockHandler
:具体流控回调方法。fallbackClass
:代码发生错误时的回调方法。fallback
:具体错误回调方法。public static String handler(BlockException blockException) {
String ruleLimitApp = blockException.getRuleLimitApp();
return "....被限流了.... "+ruleLimitApp;
}
public static String fallBack() {
return "....系统运行异常....";
