ssh增删改查的代码

我想寻求用三大框架实现增删改查的代码

Answer 1

/**
* 删除用户信息
* @return
*/
public int delUser(Users u){
try{
Users users = (Users)super.getHibernateTemplate().get(Users.class, u.getUserId());
super.getHibernateTemplate().delete(users);
}catch(Exception e){
return 0;
}
return 1;
}

/**
* 添加用户信息
*/
public int addUsers(Users users) {
try {
super.getHibernateTemplate().save(users);
} catch (Exception e) {
e.printStackTrace();
return 0;
}
return 1;
}

/**
* 获取用户信息总数
* @return
*/
public int selCountUsers(){
int count = 0;
try{
String hql = "from Users as u";
count = (Integer)super.getHibernateTemplate().find(hql).size();
}catch(Exception e){
return 0;
}
return count;
}

/**
* 根据查找角色信息
* @return
*/
public Role findRoleByRoleId(int RoleId) {
Role role = new Role();
try{
String hql = "from Role as r where r.roleId=" RoleId;
role = (Role) super.getHibernateTemplate().find(hql).get(0);
}catch(Exception e){
return null;
}
return role;
}

/**
* 更该用户信息
* @param users
* @return
*/
public int updateUserInfo(Users users) {
try{
super.getHibernateTemplate().update(users);
}catch(Exception e){
e.printStackTrace();
return 0;
}
return 1;
}
