Spring CommonsRequestLoggingFilter not log body

Hi,

I am using Spring CommonsRequestLoggingFilter for log requests and responses in my application.

I configured it

```
@Configuration
public class RequestLoggingFilterConfig {

@Bean
public CommonsRequestLoggingFilter logFilter() {

CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter()
filter.setIncludeQueryString(true)
filter.setIncludePayload(true)
filter.setIncludeHeaders(true)
filter.setIncludeClientInfo(true)

return filter
}
}
```
body request contains

`{
"interactionId" : "6d1ed753-8169-4475-8a52-637946b35a0d"
}`

and this is the logs
`10:20:56.690 [http-nio-8094-exec-8] DEBUG - Line 47 in o.s.w.f.CommonsRequestLoggingFilter - Before request [uri=/advisor/lookup;client=0:0:0:0:0:0:0:1;headers={accept=[application/json], grant=[grant], cache-control=[no-cache], postman-token=[52a3671a-5298-4608-a0a9-d417851449f1], user-agent=[PostmanRuntime/7.1.5], host=[localhost:8094], accept-encoding=[gzip, deflate], content-length=[61], connection=[keep-alive], Content-Type=[application/json;charset=UTF-8]}]`

### Environment Information

- **Operating System**: Ubuntu 16.04LTS
- **Grails Version:** 3.2.0
- **JDK Version:** jdk1.8.0_31

The same configuration with Spring Boot works good.

Any suggestions?

Thanks,
Mario.
