Spring Boot 1.4.1 and Cassandra 3.x

Question

I want to use Cassandra 3.x in a Spring Boot project. I found out that the current release version of the Spring Data Cassandra project only supports Cassandra 2.x. So I wanted to use the DataStax Driver instead of the Spring Data Cassandra project. I added ``` compile 'com.datastax.cassandra:cassandra-driver-core:3.1.1' ``` as a dependency. Now I can insert values into a keyspace on a Cassandra cluster. But when running tests for a REST controller I get an error ``` java.lang.NoClassDefFoundError: io/netty/handler/codec/http/FullHttpRequest ``` So I added ``` compile 'io.netty:netty-all:4.1.6.Final' ``` as a dependency and the error went away. But now all tests using ``` TestRestTemplate.postForObject(...) ``` or ``` TestRestTemplate.put(...) ``` fail. But using ``` TestRestTemplate.getForObject(...) ``` works as expected. I assume there's some clash in the dependencies of Spring Boot and the Netty version I added as a dependency. I found out that the latest version of the DataStax C…

Accepted Answer

I stick to using Spring Data Cassandra 1.5.0.M1 and Cassandra driver 3.1.1 using the following version overrides:

```
ext['spring.version'] = '5.0.0.M2'
ext['spring-data-releasetrain.version'] = 'Ingalls-M1'
ext['cassandra-driver.version'] = '3.1.1'
```

To make Cassandra driver functionality work I had to add Netty as a dependency.

```
compile 'io.netty:netty-all:4.1.6.Final'
```

To make `TestRestTemplate.postForObject(...)` and `TestRestTemplate.put(...)` I had to provide a `RestTemplateBuilder` `@Bean` and configure it to use `SimpleClientHttpRequestFactory`.

```
@TestConfiguration
static class TestConfig {
    @Bean
    public RestTemplateBuilder restTemplateBuilder() {
        return new RestTemplateBuilder().detectRequestFactory(false).requestFactory(SimpleClientHttpRequestFactory.class);
    }
}
```
