很抱歉,我无法提供完整的 SSM 框架项目的 Java 代码,因为这需要根据具体的业务需求和实现进行开发。但是,我可以给您提供一个简单的 SSM 框架项目的示例代码,以供参考:
1. 实体类代码
```
public class User {
private int id;
private String name;
private int age;
// 省略 getter 和 setter 方法
}
```
2. DAO 层接口代码
```
public interface UserDao {
User getUserById(int id);
void addUser(User user);
void updateUser(User user);
void deleteUser(int id);
}
```
3. DAO 层实现代码
```
@Repository
public class UserDaoImpl implements UserDao {
@Autowired
private SqlSession sqlSession;
@Override
public User getUserById(int id) {
return sqlSession.selectOne("getUserById", id);
}
@Override
public void addUser(User user) {
sqlSession.insert("addUser", user);
}
@Override
public void updateUser(User user) {
sqlSession.update("updateUser", user);
}
@Override
public void deleteUser(int id) {
sqlSession.delete("deleteUser", id);
}
}
```
4. Service 层接口代码
```
public interface UserService {
User getUserById(int id);
void addUser(User user);
void updateUser(User user);
void deleteUser(int id);
}
```
5. Service 层实现代码
```
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public User getUserById(int id) {
return userDao.getUserById(id);
}
@Override
public void addUser(User user) {
userDao.addUser(user);
}
@Override
public void updateUser(User user) {
userDao.updateUser(user);
}
@Override
public void deleteUser(int id) {
userDao.deleteUser(id);
}
}
```
6. Controller 层代码
```
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/user/{id}")
@ResponseBody
public User getUserById(@PathVariable("id") int id) {
return userService.getUserById(id);
}
@RequestMapping(value = "/user", method = RequestMethod.POST)
@ResponseBody
public String addUser(@RequestBody User user) {
userService.addUser(user);
return "success";
}
@RequestMapping(value = "/user", method = RequestMethod.PUT)
@ResponseBody
public String updateUser(@RequestBody User user) {
userService.updateUser(user);
return "success";
}
@RequestMapping(value = "/user/{id}", method = RequestMethod.DELETE)
@ResponseBody
public String deleteUser(@PathVariable("id") int id) {
userService.deleteUser(id);
return "success";
}
}
```
以上代码是一个简单的 SSM 框架项目示例,其中包含了实体类、DAO 层、Service 层和 Controller 层的代码。需要注意的是,这只是一个示例,实际开发中需要根据具体的业务需求进行相应的修改和补充。
