哈喽~我来啦。这篇blog给大家分享一下SSH+MySQL实现增删改查
准备工作：创建一个web项目，加入所需要的JAR包。分包分模块，配置所需要的核心配置文件。如果不会的小伙伴去看我https://blog.csdn.net/Ccccyxji/article/details/83388503 这篇文章哦！
Ok~贴代码
1、 User.java
public class User {
private Integer id;
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "User [id=" + id + ", name=" + name + "]";
}
public User(Integer id, String name) {
super();
this.id = id;
this.name = name;
}
public User() {
super();
// TODO Auto-generated constructor stub
}
}
2、user.hbm.xml
<hibernate-mapping>
<class name="com.baidu.pojo.User" table="user">
<id name="id" column="id" type="int">
<generator class="native"></generator>
</id>
<property name="name"></property>
</class>
</hibernate-mapping>
3、UserdaoI.java
public interface UserDaoI {
List<User> findList();
void delete(User user);
void add(User user);
User toUpdate(Integer id);
void update(User user);
}
4、UserDaoImpl.java
@Repository
public class UserdaoImpl implements UserDaoI{
@Autowired
private HibernateTemplate hibernateTemplate;
public List<User> findList() {
List list = hibernateTemplate.find("from User");
return list;
}
public void delete(User user) {
hibernateTemplate.delete(user);
}
public void add(User user) {
hibernateTemplate.save(user);
}
public void update(User user) {
hibernateTemplate.update(user);
}
public User toUpdate(Integer id) {
User user = hibernateTemplate.get(User.class, id);
return user;
}
}
5、UserServiceI.java
public interface UserServiceI {
List<User> findList();
void delete(User user);
void add(User user);
void update(User user);
User toUpdate(Integer id);
}
6、UserServiceImpl.java
@Service
public class UserServiceImpl implements UserServiceI{
@Autowired
private UserDaoI userDao;
public List<User> findList() {
return userDao.findList();
}
public void delete(User user) {
userDao.delete(user);
}
public void add(User user) {
userDao.add(user);
}
public void update(User user) {
userDao.update(user);
}
public User toUpdate(Integer id) {
return userDao.toUpdate(id);
}
}
7、UserController.java
@Controller
@Scope(value=“prototype”)
public class UserController extends ActionSupport implements ModelDriven{
@Autowired
private UserServiceI userService;
HttpServletRequest request = ServletActionContext.getRequest();
private User user=new User();
public String list(){
List<User> list = userService.findList();
request.setAttribute("list", list);
return "list";
}
public String delete(){
int id= user.getId();
userService.delete(user);
return "delete";
}
public String add(){
userService.add(user);
return "add";
}
public String toUpdate(){
User user1 = userService.toUpdate(user.getId());
request.setAttribute("user", user1);
return "toUpdate";
}
public String update(){
userService.update(user);
return "update";
}
public User getModel() {
// TODO Auto-generated method stub
return user;
}
}
