private int id;
#Column
private String category1;

}
public void setId(int id) {

}
public String getCategory1() {
return category1;
}
public void setCategory1(String category1) {

}
public String getDesccategory1() {
return desccategory1;
}
public void setDesccategory1(String desccategory1) {
this.desccategory1 = desccategory1;

This is my Dao class
public interface CategoriesDao {
public void add(CategoriesModel categories);
public void edit(CategoriesModel categories);
public void delete(int id);
public CategoriesModel getCategoriesModel(int id);
public List getAllCategoriesModel();
}
This is my Dao impl class
#Repository
public class CategoriesDaoImpl implements CategoriesDao {
#Autowired
private SessionFactory session;
#Override
public void add(CategoriesModel categories) {
session.getCurrentSession().save(categories);
//this "categories" is a table name
}
#Override
public void edit(CategoriesModel categories) {
session.getCurrentSession().update(categories);
//this "categories" is a table name
}
#Override
public void delete(int id) {
session.getCurrentSession().delete(getCategoriesModel(id));
//this "id" is a feild in Model
}
#Override
public CategoriesModel getCategoriesModel(int id) {
return (CategoriesModel) session.getCurrentSession().get(CategoriesModel.class, id);
}
#Override
public List getAllCategoriesModel() {
return session.getCurrentSession().createQuery("from CategoriesModel").list();
//this "CategoriesModel" is a its model name
}
This is my service class
public void add(CategoriesModel categories);
public void edit(CategoriesModel categories);
public void delete(int id);
public CategoriesModel getCategoriesModel(int id);
public List getAllCategoriesModel();
This is my service impl class
#Service
public class CategoriesServiceImpl implements CategoriesService {
#Autowired
private CategoriesDao CategoriesDao;
#Transactional
public void add(CategoriesModel categories) {
CategoriesDao.add(categories);
}
#Transactional
public void edit(CategoriesModel categories) {
CategoriesDao.edit(categories);
}
#Transactional
public void delete(int id) {
CategoriesDao.delete(id);
}
#Transactional
public CategoriesModel getCategoriesModel(int id) {
return CategoriesDao.getCategoriesModel(id);
}
#Transactional
public List getAllCategoriesModel() {
return CategoriesDao.getAllCategoriesModel();
}
this is my controller class
#Autowired
private CategoriesService CategoriesService;
#RequestMapping("/")
public String setupForm(Map<String, Object> map) {
CategoriesModel categories = new CategoriesModel();
//Create a new object from details Model
map.put("category", categories);
//new created object is assign and view name
map.put("categoriesList", CategoriesService.getAllCategoriesModel());
//view feild assign list in view page
System.out.println(categories);
return "allcategories";
//return page(view name)
}
this is my view
<c:forEach items="${categoriesList}" var="category">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
<div id="category">
<div class="col-lg-2 col-md-2 col-sm-4 col-xs-6 ">
<a href="" target="_self"><img src="images/properties/cars.png" class="img-responsive">
<div class="link">
<p>${category.category1}</p>
