# 使用指南
### 在启动类上加入@EnableCreateDiversionProxy
```java
@SpringBootApplication
@EnableCreateDiversionProxy
public class StartApp {
  public static void main(String[] args) {
    SpringApplication.run(StartApp.class,args);
  }
}
```
### 接口类

---
1. 在接口上添加 @CreateDiversionProxy 表示代理实现类的选择
2. 在接口方法添加 @Diverter(key="#key") 指定分流的方法和分流的key获取逻辑
```java
@CreateDiversionProxy(selector = DemoSelector.class)
public interface TestService {

  @Diverter(key = "#key")
  public void hello(String key);
}
```
> key 语法支持spel语法
---

### 实现类即被代理类
实现1
```java
@DiversionService(version = "v1")
public class TestServiceV1Impl implements TestService {
  
  @Override
  public void hello(String key) {
    System.out.println("hello v1");
  }
}
```
实现2
```java
@DiversionService(version = "v2")
public class TestServiceV2Impl implements TestService{

  @Override
  public void hello(String key) {
    System.out.println("hello v2");
  }
}
```
> @DiversionService 会自动注入spring bean不需要@Component,@Service等注解
---
### 自定义分流处理器
```java
public class DemoSelector implements DiversionSelector {
  @Override
  public Object nonDivert(Map<String, Object> proxyMap) {
    return proxyMap.get("v1");
  }
  @Override
  public Object divert(String key, Map<String, Object> proxyMap) {
    return proxyMap.get(key);
  }
}
```

### 大功告成了
 实现根据参数key来动态调用不同接口实现
