短信验证码登录思路

短信验证码登录

public class ValidateCode {
    private String code;
    //有效期
    private LocalDateTime expireTime;

    public ValidateCode(String code, int expireTime) {
        this.code = code;
        this.expireTime = LocalDateTime.now().plusSeconds(expireTime);
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public LocalDateTime getExpireTime() {
        return expireTime;
    }

    public void setExpireTime(LocalDateTime expireTime) {
        this.expireTime = expireTime;
    }

    public boolean isExpried() {
        return LocalDateTime.now().isAfter(expireTime);
    }

}

/**
 * 短信发送接口
 */
public interface SmsCodeSender {
    void send(String mobile, String code);
}

public class DefaultSmsCodeSender implements SmsCodeSender {
    @Override
    public void send(String mobile, String code) {
        System.out.println("向手机"+mobile+"发送短信验证码"+code);
    }
}

@Component("smsValidateCodeGenerator")
public class SmsCodeGenerator implements ValidateCodeGenerator {
    @Autowired
    private SecurityProperties securityProperties;
    public void setSecurityProperties(SecurityProperties securityProperties) {
        this.securityProperties = securityProperties;
    }
    @Override
    public ValidateCode generate(HttpServletRequest request) {
        String code = RandomStringUtils.randomNumeric(securityProperties.getCode().getSmsCode().getLength());
        return new ValidateCode(code, securityProperties.getCode().getSmsCode().getExpireIn());
    }
}

只有在用户没有实现smsCodeSender时才会使用默认实现

@Configuration
public class ValidateCodeBeanConfig {
    @Autowired
    private SecurityProperties securityProperties;

    @Bean
    @ConditionalOnMissingBean(name = "smsCodeSender")
    public SmsCodeSender smsCodeSender(){
        return new DefaultSmsCodeSender();
    }
}

@RestController
public class ValidateCodeController {
    public static final String SESSION_KEY_SMS = "smscode";

    @Autowired
    @Qualifier("smsValidateCodeGenerator")
    private ValidateCodeGenerator smsValidateCodeGenerator;

    @Autowired
    private SmsCodeSender smsCodeSender;

    @GetMapping("/code/sms")
    public void getsmsCaptcha(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ValidateCode smsCode = smsValidateCodeGenerator.generate(request);
        request.getSession().setAttribute(SESSION_KEY_SMS,smsCode);
        smsCodeSender.send(ServletRequestUtils.getRequiredStringParameter(request,"mobile"),smsCode.getCode());
    }
}

现在已经有了两种验证方式，接下来我们进行代码重构

用到一个session的操作工具SessionStrategy，需要引入依赖

        <dependency>
            <groupId>org.springframework.social</groupId>
            <artifactId>spring-social-web</artifactId>
            <version>1.1.6.RELEASE</version>
        </dependency>

/**
 * 校验码处理器，封装不同校验码的处理逻辑
 */
public interface ValidateCodeProcessor {
    //验证码放入session时的前缀
    String SESSION_KEY_PREFIX = "SESSION_KEY_FOR_CODE_";
    //创建校验码 ServletWebRequest 已经包含request response
    void create(ServletWebRequest request) throws Exception;
}

public abstract class AbstractValidateCodeProcessor<C extends ValidateCode> implements ValidateCodeProcessor {
    private SessionStrategy sessionStrategy = new HttpSessionSessionStrategy();
    /**
     * 收集系统中所有的 {@link ValidateCodeGenerator} 接口的实现。
     */
    @Autowired
    private Map<String, ValidateCodeGenerator> validateCodeGenerators;

    @Override
    public void create(ServletWebRequest request) throws Exception {
        C validateCode = generate(request);
        save(request,validateCode);
        send(request,validateCode);
    }

    /**
     * 保存验证码到session
     * @param request
     * @param validateCode
     */
    private void save(ServletWebRequest request, C validateCode){
        sessionStrategy.setAttribute(request,getSessionKey(request),validateCode);

    }

    private String getSessionKey(ServletWebRequest request){
        return SESSION_KEY_PREFIX + getProcessorType(request).toUpperCase();
    }

    /**
     * 发送验证码有子类实现
     * @param request
     * @param validateCode
     * @throws Exception
     */
    protected abstract void send(ServletWebRequest request, C validateCode) throws Exception;

    //生成验证码
    @SuppressWarnings("unchecked")
    private C generate(ServletWebRequest request) {
        String type = getProcessorType(request);
        ValidateCodeGenerator validateCodeGenerator = validateCodeGenerators.get(type + "CodeGenerator");
        return (C) validateCodeGenerator.generate(request);
    }

    //根据请求的url获取校验码的类型
    private String getProcessorType(ServletWebRequest request){
        return StringUtils.substringAfter(request.getRequest().getRequestURI(),"/code/");
    }
}

public class ValidateCode {
    private String code;
    //有效期
    private LocalDateTime expireTime;

    public ValidateCode(String code, int expireTime) {
        this.code = code;
        this.expireTime = LocalDateTime.now().plusSeconds(expireTime);
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public LocalDateTime getExpireTime() {
        return expireTime;
    }

    public void setExpireTime(LocalDateTime expireTime) {
        this.expireTime = expireTime;
    }

    public boolean isExpried() {
        return LocalDateTime.now().isAfter(expireTime);
    }
}

public class ImageCode extends ValidateCode {
    private BufferedImage image;

    public ImageCode(String code, int expireTime,BufferedImage image) {
        super(code,expireTime);
        this.image = image;
    }

    public BufferedImage getImage() {
        return image;
    }

    public void setImage(BufferedImage image) {
        this.image = image;
    }
}

@Component("imageCodeProcessor")
public class ImageCodeProcessor extends AbstractValidateCodeProcessor<ImageCode> {

    @Override
    protected void send(ServletWebRequest request, ImageCode validateCode) throws Exception {
        ServletOutputStream out = request.getResponse().getOutputStream();
        ImageIO.write(validateCode.getImage(),"jpg",out);
    }
}

短信的

@Component("smsCodeProcessor")
public class SmsCodeProcessor extends AbstractValidateCodeProcessor<ValidateCode> {
    @Autowired
    private SmsCodeSender smsCodeSender;
    @Override
    protected void send(ServletWebRequest request, ValidateCode validateCode) throws Exception {
        String mobile = ServletRequestUtils.getRequiredStringParameter(request.getRequest(), "mobile");
        smsCodeSender.send(mobile, validateCode.getCode());
    }
}

默认bean配置

@Configuration
public class ValidateCodeBeanConfig {
    @Autowired
    private SecurityProperties securityProperties;

    @Bean
    @ConditionalOnMissingBean(name = "imageCodeGenerator")
    public ValidateCodeGenerator imageCodeGenerator(){
        ImageCodeGenerator codeGenerator = new ImageCodeGenerator();
        codeGenerator.setSecurityProperties(securityProperties);
        return codeGenerator;
    }

    @Bean
    @ConditionalOnMissingBean(name = "smsCodeSender")
    public SmsCodeSender smsCodeSender(){
        return new DefaultSmsCodeSender();
    }
}

修改controller

@RestController

    @Autowired

    @GetMapping("/code/{type}")
    public void getCaptcha(@PathVariable("type") String type, HttpServletRequest request, HttpServletResponse response) throws Exception {
        validateCodeProcessors.get(type+"CodeProcessor").create(new ServletWebRequest(request,response));
    }
}

修改WebSecurityConfig加入ValidateCodeFilter与smsCodeAuthenticationSecurityConfig

                    .apply(smsCodeAuthenticationSecurityConfig);
    }
    @Bean
    public UserDetailsService userDetails(){
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("user").password(passwordEncoder.encode("123")).roles("USER").build());
