SpringSecurity加密认证

加密认证

在IOC容器中提供加密对象

<!--加密对象-->
<bean id="passwordEncoder"
class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
<!--设置Spring Security认证用户信息的来源-->
    <security:authentication-manager>
        <security:authentication-provider user-service-ref="userServiceImpl">
        <!--指定认证使用的加密对象-->
        <security:password-encoder ref="passwordEncoder"/>
    </security:authentication-provider>
</security:authentication-manager>

修改认证方法

去掉{noop}，该方法可以让我们的密码不加密

@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
    SysUser sysUser = userDao.findByName(username);
    if(sysUser==null){
        //若用户名不对，直接返回null，表示认证失败。
        return null;
    }
    List<SimpleGrantedAuthority> authorities = new ArrayList<>();
    List<SysRole> roles = sysUser.getRoles();
    for (SysRole role : roles) {
    	authorities.add(new SimpleGrantedAuthority(role.getRoleName()));
    }
    //最终需要返回一个SpringSecurity的UserDetails对象，{noop}表示不加密认证。
    return new User(sysUser.getUsername(), sysUser.getPassword(), authorities);
}

修改添加用户的操作

@Service
@Transactional
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;
    @Autowired
    private RoleService roleService;
    @Autowired
    private BCryptPasswordEncoder passwordEncoder;
    @Override
    public void save(SysUser user) {
        //对密码进行加密，然后再入库
        user.setPassword(passwordEncoder.encode(user.getPassword()));
        userDao.save(user);
	}
}

手动将数据库中用户密码改为加密后的密文
