## Dubbo支持
|
||||
## DataSource支持
|
||||
|
||||
[Dubbo](http://dubbo.apache.org/)是一款高性能Java RPC框架。
|
||||
Sentinel内部提供了[动态规则的扩展实现DataSource](https://github.com/alibaba/Sentinel/wiki/%E5%8A%A8%E6%80%81%E8%A7%84%E5%88%99%E6%89%A9%E5%B1%95#datasource-%E6%89%A9%E5%B1%95)。
|
||||
|
||||
Sentinel提供了[sentinel-dubbo-adapter](https://github.com/alibaba/Sentinel/tree/master/sentinel-adapter/sentinel-dubbo-adapter)模块用来支持Dubbo服务调用的限流降级。sentinel-starter默认也集成了该功能。
|
||||
Sentinel starter整合了目前存在的4类DataSource。只需要在配置文件中进行相关配置，即可在Spring容器中自动注册DataSource。
|
||||
|
||||
比如有个FooService服务，定义如下：
|
||||
比如要定义一个FileRefreshableDataSource，配置如下：
|
||||
|
||||
package org.springframework.cloud.alibaba.cloud.examples.dubbo.FooService;
|
||||
public interface FooService {
|
||||
String hello(String name);
|
||||
spring.cloud.sentinel.datasource.type=file
|
||||
spring.cloud.sentinel.datasource.recommendRefreshMs=2000
|
||||
spring.cloud.sentinel.datasource.bufSize=2048
|
||||
spring.cloud.sentinel.datasource.charset=utf-8
|
||||
spring.cloud.sentinel.datasource.configParser=myParser
|
||||
spring.cloud.sentinel.datasource.file=/Users/you/rule.json
|
||||
|
||||
然后使用`@SentinelDataSource`注解修饰DataSource即可注入：
|
||||
|
||||
@SentinelDataSource("spring.cloud.sentinel.datasource")
|
||||
private DataSource dataSource;
|
||||
|
||||
`@SentinelDataSource`注解的value属性可以不填。默认值就是spring.cloud.sentinel.datasource。
|
||||
|
||||
value属性代表配置前缀。示例中会去找spring.cloud.sentinel.datasource.xxx相关的配置。
|
||||
|
||||
spring.cloud.sentinel.datasource.type就是对应的DataSource类型。
|
||||
|
||||
spring.cloud.sentinel.datasource.recommendRefreshMs里的recommendRefreshMs对应相关DataSource的属性。
|
||||
|
||||
spring.cloud.sentinel.datasource.configParser代表ConfigParser在Spring容器里的name。如果没找到，会抛出异常。
|
||||
|
||||
type目前支持file, nacos, zk, apollo。
|
||||
|
||||
### 自定义DataSource
|
||||
|
||||
自定义DataSource只需要两部。
|
||||
|
||||
1. 定义DataSource
|
||||
|
||||
public class CustomDataSource implements DataSource {
|
||||
private String fieldA;
|
||||
private String fieldB;
|
||||
...
|
||||
}
|
||||
|
||||
该服务在Sentinel下对应的资源名是 `org.springframework.cloud.alibaba.cloud.examples.dubbo.FooService:hello(java.lang.String)` 。
|
||||
2. 装配DataSource。有两种方式处理。
|
||||
|
||||
在Consumer端进行限流的话，需要处理SentinelRpcException。
|
||||
* 直接构造DataSource
|
||||
|
||||
FooService service = applicationContext.getBean(FooService.class);
|
||||
|
||||
for (int i = 0; i < 15; i++) {
|
||||
try {
|
||||
String message = service.hello("Jim");
|
||||
} catch (SentinelRpcException ex) {
|
||||
System.out.println("Blocked");
|
||||
} catch (Exception ex) {
|
||||
ex.printStackTrace();
|
||||
}
|
||||
@Bean
|
||||
public CustomDataSource customDataSource() {
|
||||
CustomDataSource customDataSource =
|
||||
new CustomDataSource();
|
||||
customDataSource.setFieldA("valueA");
|
||||
customDataSource.setFieldB("valueB");
|
||||
...
|
||||
return customDataSource;
|
||||
}
|
||||
|
||||
在Provider端进行限流的话，Consumer端调用的话会抛出RpcException。因为Provider端被限流抛出了SentinelRpcException。
|
||||
* 在classpath:/META-INF/sentinel-datasource.properties中管理DataSource信息
|
||||
|
||||
### Dubbo 应用启动
|
||||
custom = yourpackage.CustomDataSource
|
||||
|
||||
在启动ServiceApplication的前提下，再启动ConsumerApplication。
|
||||
在application.properties中定义DataSource
|
||||
|
||||
spring.cloud.sentinel.datasource.type = custom
|
||||
spring.cloud.sentinel.datasource.fieldA = valueA
|
||||
spring.cloud.sentinel.datasource.fieldB = valueB
|
||||
|
||||
注意：由于目前Sentinel的AbstractDataSource需要有个ConfigParser作为构造函数中的参数，并且它的子类的构造都是通过多个参数的构造函数构造的。
|
||||
所以目前所有的Sentinel starter中的DataSource都是基于FactoryBean并且通过设置属性构造的。如果有这方面的需求，需要再多加一个registerFactoryBean过程。
|
||||
|
||||
SentinelDataSourceRegistry.registerFactoryBean("custeom", CustomDataSourceFactoryBean.class);
|
||||
|
||||
如果自定义DataSource可以注入属性，那么没有必要使用SentinelDataSourceRegistry注册FactoryBean。
|
||||
|
||||
ConsumerApplication在Consumer端设置了限流规则，所以启动完成后查看控制台的打印信息，会发现部分调用被Block。
|
||||

## Dubbo
|
||||
## DataSource
|
||||
|
||||
[Dubbo](http://dubbo.apache.org/) is a high-performance, java based open source RPC framework.
|
||||
Sentinel provide [DataSource](https://github.com/alibaba/Sentinel/blob/master/sentinel-extension/sentinel-datasource-extension/src/main/java/com/alibaba/csp/sentinel/datasource/DataSource.java) to manage dynamic rules.
|
||||
|
||||
Sentinel provide a module named [sentinel-dubbo-adapter](https://github.com/alibaba/Sentinel/tree/master/sentinel-adapter/sentinel-dubbo-adapter) to support dubbo.sentinel-starter integrates this feature by default.
|
||||
Sentinel starter integrated 4 DataSources provided by Sentinel. It will be register into Spring Context if you write some configs in `application.properties`.
|
||||
|
||||
For example, a service named FooService, see the code below:
|
||||
If you want to define FileRefreshableDataSource:
|
||||
|
||||
package org.springframework.cloud.alibaba.cloud.examples.dubbo.FooService;
|
||||
public interface FooService {
|
||||
String hello(String name);
|
||||
spring.cloud.sentinel.datasource.type=file
|
||||
spring.cloud.sentinel.datasource.recommendRefreshMs=2000
|
||||
spring.cloud.sentinel.datasource.bufSize=2048
|
||||
spring.cloud.sentinel.datasource.charset=utf-8
|
||||
spring.cloud.sentinel.datasource.configParser=myParser
|
||||
spring.cloud.sentinel.datasource.file=/Users/you/rule.json
|
||||
|
||||
then use `@SentinelDataSource` to annotate DataSource:
|
||||
|
||||
@SentinelDataSource("spring.cloud.sentinel.datasource")
|
||||
private DataSource dataSource;
|
||||
|
||||
The value() of `@SentinelDataSource` is not required, it means the prefix of configuration. Default value is `spring.cloud.sentinel.datasource`.
|
||||
|
||||
spring.cloud.sentinel.datasource.type means the type of DataSource.
|
||||
|
||||
spring.cloud.sentinel.datasource.recommendRefreshMs means the recommendRefreshMs property of specified DataSource.
|
||||
|
||||
spring.cloud.sentinel.datasource.configParser means the name of spring bean that type is ConfigParser. If the bean is not exists, will throw exception.
|
||||
|
||||
Now datasource type support 4 categories: file, nacos, zk, apollo.
|
||||
|
||||
### User-defined DataSource
|
||||
|
||||
User-defined DataSource need 2 steps.
|
||||
|
||||
1. Define DataSource
|
||||
|
||||
public class CustomDataSource implements DataSource {
|
||||
private String fieldA;
|
||||
private String fieldB;
|
||||
...
|
||||
}
|
||||
|
||||
The resource name of this service is `org.springframework.cloud.alibaba.cloud.examples.dubbo.FooService:hello(java.lang.String)` .
|
||||
2. Assemble DataSource. There are 2 ways to do this.
|
||||
|
||||
You should handle SentinelRpcException if rpc invocation was be limited on Consumer side:
|
||||
* Construct DataSource directly
|
||||
|
||||
FooService service = applicationContext.getBean(FooService.class);
|
||||
|
||||
for (int i = 0; i < 15; i++) {
|
||||
try {
|
||||
String message = service.hello("Jim");
|
||||
} catch (SentinelRpcException ex) {
|
||||
System.out.println("Blocked");
|
||||
} catch (Exception ex) {
|
||||
ex.printStackTrace();
|
||||
}
|
||||
@Bean
|
||||
public CustomDataSource customDataSource() {
|
||||
CustomDataSource customDataSource = new CustomDataSource();
|
||||
customDataSource.setFieldA("valueA");
|
||||
customDataSource.setFieldB("valueB");
|
||||
...
|
||||
return customDataSource;
|
||||
}
|
||||
|
||||
It will throw RpcException on Consumer side if it was be limited on Provider side, because Provider side throw SentinelRpcException in this scene.
|
||||
* define DataSource metadata in `classpath:/META-INF/sentinel-datasource.properties`
|
||||
|
||||
### Dubbo Start Application
|
||||
custom = yourpackage.CustomDataSource
|
||||
|
||||
You can startup ConsumerApplication after ServiceApplication startup.
|
||||
define configuration in `application.properties`
|
||||
|
||||
ConsumerApplication init flow control rules after startup, so you will find some invocations have been blocked in console.
|
||||
spring.cloud.sentinel.datasource.type = custom
|
||||
spring.cloud.sentinel.datasource.fieldA = valueA
|
||||
spring.cloud.sentinel.datasource.fieldB = valueB
|
||||
|
||||
Note: The AbstractDataSource of Sentinel need a ConfigParser as a constructor param and the subclass of AbstractDataSource was construct by multi-param constructor.
|
||||
Now All DataSources in starter was construct by FactoryBean. If you want to do it in this way, you should register FactoryBean by SentinelDataSourceRegistry.
|
||||
|
||||
SentinelDataSourceRegistry.registerFactoryBean("custeom", CustomDataSourceFactoryBean.class);
|
||||
|
||||
It is no need to using SentinelDataSourceRegistry to register FactoryBean if your User-defined DataSource can inject fields.
