Spring Rest Template Logger

A simple way to log Spring RestTemplate requests and responses.

Requirements

  • Spring web 4+
  • Slf4j 1.7.7+

How it works

This project includes a new RestTemplate interceptor (RequestLoggerInterceptor) that logs the request and response. For this, you have to add this interceptor to your RestTemplate instance. Also, you will need to change the default request factory for a BufferingClientHttpRequestFactory, this is necessary to log de response body.

How to use

Without Spring Boot

Add the dependency to pom.xml

<dependency>
   <groupId>ar.com.onready</groupId>
   <artifactId>spring-resttemplate-logger</artifactId>
   <version>1.0.0</version>
</dependency>

Then, configure your RestTemplate instance:

RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new BufferingClientHttpRequestFactory(new SimpleClientHttpRequestFactory()));
List<ClientHttpRequestInterceptor> interceptors = restTemplate.getInterceptors();
if (CollectionUtils.isEmpty(interceptors)) {
  interceptors = new ArrayList<ClientHttpRequestInterceptor>(1);
}
interceptors.add(new RequestLoggerInterceptor());
restTemplate.setInterceptors(interceptors);

Important

In order to view the logs, the package ar.com.onready.springrequestlogger must be log in debug mode.
