Spring Boot + Rest Template full logging

This example shows how to log all the requests/responses from a Rest Template call.

About the example

• Spring Boot 1.5.6.RELEASE
• Spring Web 4.3.10.RELEASE
• Slf4j 1.7.25
• Logback 1.1.11
• Groovy 2.4.12

The interceptor FullLoggingInterceptor is the responsible to print all the requests made through restTemplate.

For this, we need to specify the interceptor for this object declaring in a @Configuration class, in this example: ApplicationConfiguration

@Configuration
class ApplicationConfiguration {

  @Autowired
  FullLoggingInterceptor fullLoggingInterceptor

  @Bean
  RestTemplate restTemplate(){
    RestTemplate restTemplate = new RestTemplate()
    restTemplate.interceptors = [fullLoggingInterceptor]
    restTemplate
  }
}

How to build the example

 ./gradlew clean build

How to Run

 ./gradlew bootRun

Call the endpoint:

http://localhost:8080/spring-resttemplate-log/

Then check in the logs the result:
