How to fix Found use of deprecated [org.hibernate.id.SequenceGenerator] sequence-based id generator; use org.hibernate.id.enhanced.SequenceStyleGenerator instead

Question

I have following code in my POJO
```java
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
```
On startup Hibernate giving me the following warning
```java
HHH90000014: Found use of deprecated [org.hibernate.id.SequenceGenerator] sequence-based id generator;
use org.hibernate.id.enhanced.SequenceStyleGenerator instead. 
See Hibernate Domain Model Mapping Guide for details.
```

Start using GenericGenerator for sequence generation.

declare your GenericGenerator with the following code
```java
	@GenericGenerator(
	        name = "userSequenceGenerator",
	        strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
	        parameters = {
	                @Parameter(name = "sequence_name", value = "userSequence"),
	                @Parameter(name = "initial_value", value = "1"),
	                @Parameter(name = "increment_size", value = "1")
	        }
	)
```
and start using it for your id field

```java
@Id
	@GeneratedValue(generator = "userSequenceGenerator")
	private Long id;
```
