SSM框架可以使用SpringMVC作为控制器,Spring作为容器管理Bean,MyBatis作为持久层框架,来实现登录注册的功能。
下面是一个简单的示例代码:
1. 在Spring MVC的Controller中实现登录和注册的处理方法:
```
@Controller
public class UserController {
@Autowired
private UserService userService;
// 登录
@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(@RequestParam("username") String username, @RequestParam("password") String password, HttpSession session) {
User user = userService.login(username, password);
if (user != null) {
session.setAttribute("user", user);
return "redirect:/index";
} else {
return "redirect:/login";
}
}
// 注册
@RequestMapping(value = "/register", method = RequestMethod.POST)
public String register(@RequestParam("username") String username, @RequestParam("password") String password) {
User user = new User();
user.setUsername(username);
user.setPassword(password);
userService.register(user);
return "redirect:/login";
}
}
```
2. 在Spring中配置MyBatis的SqlSessionFactory和MapperScannerConfigurer:
```
@Configuration
@MapperScan("com.example.dao")
public class MybatisConfig {
@Bean
public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource) {
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource);
return sessionFactoryBean;
}
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() {
MapperScannerConfigurer scannerConfigurer = new MapperScannerConfigurer();
scannerConfigurer.setBasePackage("com.example.dao");
return scannerConfigurer;
}
}
```
3. 在MyBatis的Mapper接口中定义SQL语句和对应的方法:
```
public interface UserMapper {
@Select("SELECT * FROM user WHERE username=#{username} AND password=#{password}")
User login(@Param("username") String username, @Param("password") String password);
@Insert("INSERT INTO user(username,password) VALUES(#{username},#{password})")
void register(User user);
}
```
4. 在Spring中配置数据源和事务管理器:
```
@Configuration
public class DataSourceConfig {
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/test");
dataSource.setUsername("root");
dataSource.setPassword("root");
return dataSource;
}
@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
}
```
以上就是一个简单的SSM框架实现登录注册的示例。当然,实际开发中可能会更加复杂,需要考虑到安全、性能等方面的问题。
