springmvc项目+cxf+webservice+jsp开发登录功能

好的，下面是一个基于SpringMVC、CXF、WebService和JSP的登录功能的示例代码，供你参考：

1. 创建User模型类

public class User {
    private String username;
    private String password;
    // 省略getter、setter方法
}

2. 创建UserDAO接口和UserDAOImpl实现类

public interface UserDAO {
    User findUserByUsernameAndPassword(String username, String password);
}

@Repository
public class UserDAOImpl implements UserDAO {
    @Autowired
    private SqlSessionTemplate sqlSessionTemplate;

    @Override
    public User findUserByUsernameAndPassword(String username, String password) {
        Map<String, String> params = new HashMap<>();
        params.put("username", username);
        params.put("password", password);
        return sqlSessionTemplate.selectOne("UserMapper.findUserByUsernameAndPassword", params);
    }
}

3. 创建UserService接口和UserServiceImpl实现类

public interface UserService {
    User login(String username, String password);
}

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDAO userDAO;

    @Override
    public User login(String username, String password) {
        return userDAO.findUserByUsernameAndPassword(username, password);
    }
}

4. 创建LoginController

@Controller
public class LoginController {
    @Autowired
    private UserService userService;

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(HttpServletRequest request, String username, String password) {
        User user = userService.login(username, password);
        if (user != null) {
            request.getSession().setAttribute("user", user);
            return "redirect:/index";
        } else {
            request.setAttribute("message", "用户名或密码错误");
            return "login";
        }
    }
}

5. 创建UserWebService接口和UserWebServiceImpl实现类

@WebService
public interface UserWebService {
    User login(String username, String password);
}

@Service
@WebService(endpointInterface = "com.example.UserWebService")
public class UserWebServiceImpl implements UserWebService {
    @Autowired
    private UserService userService;

    @Override
    public User login(String username, String password) {
        return userService.login(username, password);
    }
}

6. 创建CXF配置文件

在applicationContext.xml中添加以下配置：

<jaxws:endpoint id="userWebService" implementor="#userWebServiceImpl" address="/user" />
<bean id="userWebServiceImpl" class="com.example.UserWebServiceImpl" />

7. 创建JSP页面

<form action="${pageContext.request.contextPath}/login" method="post">
    <label>用户名：</label>
    <input type="text" name="username"><br>
    <label>密码：</label>
    <input type="password" name="password"><br>
    <input type="submit" value="登录">
</form>

以上是一个简单的示例，仅供参考。具体实现还需要根据你的具体需求进行调整。
