Springs RestTemplate默认连接池 [英] Springs RestTemplate default connection pool

问题描述

只是想知道RestTemplate是否开箱即用使用连接池，还是只是每次都建立一个新的连接?

Just wondering if RestTemplate out of the box uses connection pooling or does it simply establish a new connection each time ?

推荐答案

我相信RestTemplate不会使用连接池发送请求，它会使用SimpleClientHttpRequestFactory来包装标准JDK的打开和关闭连接.

I believe RestTemplate doesn’t use a connection pool to send requests, it uses a SimpleClientHttpRequestFactory that wraps a standard JDK’s HttpURLConnection opening and closing the connection.

实际上，您可以将RestTemplate配置为使用池化的实现，例如HttpComponentsClientHttpRequestFactory，但是最有可能的是，您可能还需要配置一些设置以防止请求超时.

Indeed you can configure RestTemplate to use a pooled implementation such as HttpComponentsClientHttpRequestFactory but most-likely you might also need to configure some settings to prevent requests from timing out.
