  import lombok.AllArgsConstructor;
  import lombok.Data;
  import lombok.NoArgsConstructor;
  
  @Data
  @NoArgsConstructor
  @AllArgsConstructor
  public class Role {
      private Integer id;
      private String name;

  public class HelloController {
      @GetMapping("/hello")
      public ResultModel hello() {
          return ResultModel.success(HttpStatus.OK.value(), "访问成功", "Hello developer,You successfully retrieved the data!");
      }
  }
  

JSON 响应和统一数据返回

• 响应

  public class ResponseUtil {
      public static void out(HttpServletResponse response,ResultModel resultModel){
          ObjectMapper objectMapper = new ObjectMapper();
          // 设置响应的状态为 200
          response.setStatus(HttpStatus.OK.value());
          // 设置响应的格式为 JSON 格式
          response.setContentType(MediaType.APPLICATION_JSON_VALUE);
          try {
              // 使用jackson，把json格式的resultModel写入到response的输出流中
              objectMapper.writeValue(response.getOutputStream(),resultModel);
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
  }
  

• 统一数据返回模型

  import lombok.Data;
  
  import java.io.Serializable;
  
  @Data
  public class ResultModel<T> implements Serializable {
      // 状态码
      private int code; // 1000表示成功 401 表示认证失败
      // 消息
      private String message;
      // 数据
      private T data;
  
  
      private static ResultModel resultModel = new ResultModel();
  
  
      public static ResultModel success(String message) {
          resultModel.setCode(1000);
          resultModel.setMessage(message);
          resultModel.setData(null);
          return resultModel;
      }
  
      public static ResultModel success(Object data) {
          resultModel.setCode(1000);
          resultModel.setMessage("success");
          resultModel.setData(data);
          return resultModel;
      }
  
      public static ResultModel success(String message, Object data) {
          resultModel.setCode(1000);
          resultModel.setMessage(message);
          resultModel.setData(data);
          return resultModel;
      }
  
      public static ResultModel success(Integer code, String message) {
          resultModel.setCode(1000);
          resultModel.setMessage(message);
          return resultModel;
      }
  
      public static ResultModel success(Integer code, String message, Object data) {
          resultModel.setCode(code);
          resultModel.setMessage(message);
          resultModel.setData(data);
          return resultModel;
      }
      
      public static ResultModel error() {
          resultModel.setCode(500);
          resultModel.setMessage("error");
          return resultModel;
      }
  
      public static ResultModel error(int code, String message) {
          resultModel.setCode(code);

记住我

• 实现

  package com.example.baizhisecurity.config.rememberme;
  
  import org.springframework.core.log.LogMessage;
  import org.springframework.security.core.userdetails.UserDetailsService;
  import org.springframework.security.web.authentication.rememberme.PersistentTokenBasedRememberMeServices;
  import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;
  import org.springframework.util.ObjectUtils;
  
  import javax.servlet.http.HttpServletRequest;

                  this.logger.debug(LogMessage.format("Did not send remember-me cookie (principal did not set parameter '%s')", parameter));
                  return false;
              } else {
                  return true;
              }
          }
          // 进行传统表单认证
          return super.rememberMeRequested(request, parameter);
      }
  }
  
  

跨域配置

• 这个地方很特殊,在看到的教学过程中会在当前类下创建一个配置类,设置为数据源,但在这个项目学习的过程中出现了意外的错误CORS error，在这个过程中,预检请求发送成功,但是到了最真实的请求时,就出现错误,经过不断地修改跨域配置,前期在Vue项目中添加了devServer配置,对于跨域同样是失效的。

  // http 此种配置可能未生效在前后端分离中,但是之前使用的时候是生效的,这个点暂时属于疑问，希望多多评论
  http.cors().configurationSource(configurationSource())
  
  // SpringSecurity 配置后未能生效的跨域配置
  CorsConfigurationSource configurationSource() {
      CorsConfiguration corsConfiguration = new CorsConfiguration();
      corsConfiguration.setAllowedHeaders(Arrays.asList("*"));
      corsConfiguration.setAllowedMethods(Arrays.asList("*"));
      corsConfiguration.setAllowedOrigins(Arrays.asList("*"));
      corsConfiguration.setMaxAge(3600L);
      UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
      source.registerCorsConfiguration("/**", corsConfiguration);
      return source;
  }
  

• 真实有效的解决方案

  package com.example.baizhisecurity.config;
  
  import org.springframework.context.annotation.Configuration;
  import org.springframework.web.servlet.config.annotation.CorsRegistry;
  import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
  
  /**
   * 1. 先对 SpringBoot 配置,运行跨域请求
   */
  @Configuration
  public class CorsConfig implements WebMvcConfigurer {
      @Override
      public void addCorsMappings(CorsRegistry registry) {
          // 设置允许跨域的路径
          registry.addMapping("/**")
                  // 设置允许跨域请求的域名
                  .allowedOriginPatterns("*")
                  // 是否允许 Cookie
                  .allowCredentials(true)
                  // 设置允许的请求方式
                  .allowedMethods("GET", "POST", "DELETE", "PUT")
                  // 设置允许的 header 属性
                  .allowedHeaders("*")
                  // 设置允许时间
                  .maxAge(3600L);
      }
  }
  

  // 2. 最后只需要在 SpringSecurity 的 hppt 配置跨域
  http.cors();
  

  在经过上面两步后,成功解决CORS引起的问题并成功的获取到了数据。

验证码

• 配置验证码

  @Configuration
  public class KaptchaConfig {
      @Bean
      public Producer kaptcha() {
          Properties properties = new Properties();
          properties.setProperty("kaptcha.image.width", "120");
          properties.setProperty("kaptcha.image.height", "40");
          properties.setProperty("kaptcha.textproducer.char.string", "0123456789qwertyuiopasdfghjklzxcvbnmQWERTYUIOASDFGHJKLZXCVBNM");
          properties.setProperty("kaptcha.textproducer.char.length", "4");
          Config config = new Config(properties);
          DefaultKaptcha defaultKaptcha = new DefaultKaptcha();
          defaultKaptcha.setConfig(config);
          return defaultKaptcha;
      }
  }
  

• 验证码的控制器类

  @Slf4j
  @CrossOrigin
  @RestController
  public class CaptchaController {
      @Autowired
      private Producer producer;
      @Autowired
      private StringRedisTemplate redisTemplate;
  
      @GetMapping("/captcha")
      public ResultModel getVerifyCode(HttpServletRequest request, HttpServletResponse response, HttpSession session) throws IOException {
          // 1. 生成验证码
          String text = producer.createText();
          log.info("code text: {}", text);
          // 2. TODO 放入 session/redis
          redisTemplate.opsForValue().set("kaptcha", text);
          // 3. 生成图片
          BufferedImage image = producer.createImage(text);
          FastByteArrayOutputStream fos = new FastByteArrayOutputStream();
          ImageIO.write(image, "jpg", fos);
          String base64Img = Base64.encodeBase64String(fos.toByteArray());
          return ResultModel.success(HttpStatus.OK.value(), "验证码获取成功!", base64Img);
      }
  }
  

自定义全局异常

• 验证码异常

      public KaptchaNotMatchException(String msg, Throwable cause) {
          super(msg, cause);
      }
      public KaptchaNotMatchException(String msg) {
          super(msg);
      }
  }
  

• 全局异常处理

  @ControllerAdvice
  public class GlobalExceptionHandle {
      @ResponseBody
      @ExceptionHandler(Exception.class)
      public ResultModel error(Exception e) {
          e.printStackTrace();
          return ResultModel.error(HttpStatus.INTERNAL_SERVER_ERROR.value(), "执行了全局异常处理!");
      }
  }

• 发送请求认证测试

  表单测试

代码下载

• 源代码下载

  https://gitee.com/coderitl/split-springsecurity.git

特殊点说明

• 项目整体采用的是前后端分离开发
• 前后端分离后的特点是所有响应以JSON格式显示
• 在登录页面上，需要特别的注意自定义登录页面是针对传统的WEB开发,而前后端分离是将登陆表单以JSON格式显示的

项目测试

• 测试获取验证码

  http://localhost:8080/captcha

  data是图片数据的Base64显示,前端是需要拼接的	POSTMAN测试

• 测试直接访问控制器数据

  未登陆时访问数据

  • 细节

    1. 这里需要注意，使用的时候需要在header中添加CSRF需要的键值

       第一步获取cookie中关于CSRF相关的键值

    2. 将上图中红色框中的值复制下来,添加到本次请求的header中

       CSRF配置

    3. 在添加好后,再次访问请求

       成功获得认证

    4. 下次访问时，需要删除header中CSRF的值，之后再次添加

    5. 疑问点难道每一次都需要访问一次失败的再添加cookie后才能访问成功吗?

       在前端使用的时候,是通过添加相关的配置获取的是cookie的内容，所以访问时就已经实现了添加，所以不会出现访问失败一次的现象。

    6. Vue中CSRF的配置

       • 下载插件

         # 下载 cookie 使用的插件
         npm install vue-cookie --save
         

       • 使用

         // config.js
         import axios from "axios";
         import VueCookie from "vue-cookie";
         
         axios.defaults.xsrfHeaderName = "X-CSRF-TOKEN";
         axios.defaults.xsrfCookieName = "CSRF-TOKEN";
         axios.defaults.withCredentials = "true";
         
         export function request(config) {
           // 1.创建axios的实例
           const instance = axios.create({
             baseURL: "http://localhost:8080",
             timeout: 5000,
           });
         
           // 2.axios的拦截器
           // 2.1.请求拦截的作用
           instance.interceptors.request.use(
             (config) => {
               // 在发送请求之前做些什么
               // 获取 CSRF Token
               const csrfToken = VueCookie.get("XSRF-TOKEN");
               console.log("csrfToken: " + csrfToken);
               if (csrfToken) {
                 // 在请求头中添加 CSRF Token
                 config.headers["X-XSRF-TOKEN"] = csrfToken;
               }
               return config;
             },
             (err) => {
               // 对请求错误做些什么
               return Promise.reject(err);
             }
           );
         
           // 2.2.响应拦截
           instance.interceptors.response.use(
             (res) => {
               return res.data;
             },
             (err) => {
               console.log(err);
             }
           );
         
           // 3.发送真正的网络请求
           return instance(config);
         }
