In my entities I have to use fetch = FetchType.EAGER because I have a mistake:

If I use this then my app goes correct, but the time execution is too, between page and page around 7 seconds (now bbdd has little data)

I have two problems.

* If I put FetchType.LAZY my app does not work
* If I put FetchType.EAGER my app has a lot of time of execution

PF.class (Entity) 

```
@OneToMany(fetch = FetchType.EAGER, mappedBy = "pf", cascade = CascadeType.ALL)
private Set<HDSEntity> hardwareDeviceStocks = new HashSet<HDSEntity>();

@OneToMany(fetch = FetchType.EAGER, mappedBy = "pf", cascade = CascadeType.ALL)
private Set<BSEntity> bS = new HashSet<BSEntity>();

@OneToMany(cascade = CascadeType.ALL, mappedBy = "pf", fetch = FetchType.EAGER)
private Set<CEntity> cp = new HashSet<CEntity>();

```

HDS.class (Entity)

```
 @ManyToOne(cascade = {CascadeType.ALL})
 @JoinColumn(name = "fk_pf")
 private PFEntity pf;

```

BS.class (Entity)

```
@ManyToOne(cascade = CascadeType.ALL)
 @JoinColumn(name = "fk_pf")
 private PFEntity pf;

```

Thanks. ;)
