I have a method who gets some data with Hibernate, but if the entity is Null, when I try to compare with it throws NullPointerException
ExampleController.java
@RequestMapping(value = "/example/{exampleId}")
public String exampleMethod(@PathVariable("exampleId") final Integer exampleId, final ModelMap model) {
ExampleEntity ee = this.ExampleEntityService.load(exampleId);
if (ee.exampleAnidatedEntity() == null) {
model.addAttribute("exampleAnidatedEntity", ee.exampleAnidatedEntity());
} else {
model.addAttribute("exampleAnidatedEntity", new ExampleAnidatedEntity());
}
// Do some stuff...
Change this to
if (ee!=null && ee.exampleAnidatedEntity() == null) {
This will make the checking only when ee
is not null.
