Spring RestTemplate - Need to release connection?

Question

This is my Configuration for Rest Template,

    @Bean
    @Qualifier(\"myRestService\")
    public RestTemplate createRestTemplate(@Value(\"${connection.timeout}         


        

Answer 1

The question which you have asked: Do i need to release the connection after the above call or is it taken care by RestTemplate. If we need to take care of releasing connection.

No, you do not need to close the connection on the response, if you use resttemplate.

From the apache httpclient, you need to consume the complete response (EntityUtils.consume(HttpEntity) and close the response.

This can be verified in the ClientConnectionRelease.java

But RestTemplate does this for you, to verify the same have a look into RestTemplate.java

Look for method

protected  T doExecute(URI url,...) {
 try {
        ClientHttpRequest request = this.createRequest(url, method);
        ...
        response = request.execute();
        ...
        if(responseExtractor != null) {
            var7 = responseExtractor.extractData(response);
            return var7;
        }
       ...
       ...
    } finally {
        if(response != null) {
            response.close();
        }

    }
}

Where response extractor does the work for you by consuming the response using responseExtractor.extractData(response);

And after extracting the data completely it is closing response.close() as well.
