retrofit 线程池监控

Retrofit本身没有提供线程池监控功能,但可以通过一些第三方库和工具实现线程池监控。以下是一种实现方式:
1. 在OkHttpClient中配置拦截器,用于监控线程池的使用情况。
```java
public class ThreadPoolMonitorInterceptor implements Interceptor {
private ThreadPoolExecutor executor;
public ThreadPoolMonitorInterceptor(ThreadPoolExecutor executor) {
this.executor = executor;
}
@Override
public Response intercept(Chain chain) throws IOException {
// 在执行请求之前打印线程池的状态
System.out.println("Active threads: " + executor.getActiveCount());
System.out.println("Completed tasks: " + executor.getCompletedTaskCount());
System.out.println("Task count: " + executor.getTaskCount());
return chain.proceed(chain.request());
}
}
```
2. 在创建Retrofit实例时,将上述拦截器添加到OkHttpClient中。
```java
ThreadPoolExecutor executor = new ThreadPoolExecutor(10, 10,
60L, TimeUnit.SECONDS,
new LinkedBlockingQueue<>());
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new ThreadPoolMonitorInterceptor(executor))
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.example.com/")
.client(client)
.build();
```
通过这种方式,我们可以在控制台输出线程池的状态信息,从而监控线程池的使用情况。当然,也可以将这些信息输出到日志文件中,方便后续分析和调优。
