      介绍

      在我们日常的Java开发中,免不了和其他系统的业务交互,或者微服务之间的接口调用;如果我们想保证数据传输的安全,对接口出参加密,入参解密。但是不想写重复代码,我们可以提供一个通用starter,提供通用加密解密功能。

      基础知识

      hutool-crypto加密解密工具

      hutool-crypto提供了很多加密解密工具,包括对称加密,非对称加密,摘要加密等等,这不做详细介绍。

      request流只能读取一次的问题

      问题描述

      在接口调用链中,request的请求流只能调用一次,处理之后,如果之后还需要用到请求流获取数据,就会发现数据为空。

      比如使用了filter或者aop在接口处理之前,获取了request中的数据,对参数进行了校验,那么之后就不能在获取request请求流了。

      解决办法

      继承HttpServletRequestWrapper,将请求中的流copy一份,复写getInputStream和getReader方法供外部使用。每次调用后的getInputStream方法都是从复制出来的二进制数组中进行获取,这个二进制数组在对象存在期间一致存在。

      使用Filter过滤器,在一开始,替换request为自己定义的可以多次读取流的request。

      下面这样就实现了流的重复获取:

      工具类(InpjavascriptutStreamHttpServletRequestWrapper):

      package com.mry.springboottools.validation;
      import org.apache.commons.io.IOUtils;
      import javax.servlet.ReadListener;
      import javax.servlet.ServletInputStream;
      import javax.servlet.http.HttpServletRequest;
      import javax.servlet.http.HttpServletRequestWrapper;
      import java.io.BufferedReader;
      import java.io.ByteArrayInputStream;
      import java.io.ByteArrayOutputStream;
      import java.io.IOException;
      import java.io.InputStreamReader;
      /**
       * 请求流支持多次获取
       */
      public class InputStreamHttpServletRequestWrapper extends HttpServletRequestWrapper {
          /**
           * 用于缓存输入流
           */
          private ByteArrayOutputStream cachedBytes;
          public InputStreamHttpServletRequestWrapper(HttpServletRequest request) {
              super(request);
          }
          @Override
          public ServletInputStream getInputStream() throws IOException {
              if (cachedBytes == null) {
                  // 首次获取流时,将流放入 缓存输入流 中
                  cacheInputStream();
              }
              // 从 缓存输入流 中获取流并返回
              return new CachedServletInputStream(cachedBytes.toByteArray());
          }
          @Override
          public BufferedReader getReader() throws IOException {
              return new BufferedReader(new InputStreamReader(getInputStream()));
          }
          /**
           * 首次获取流时,将流放入 缓存输入流 中
           */
          private void cacheInputStream() throws IOException {
              // 缓存输入流以便多次读取。为了方便, 我使用 org.apache.commons IOUtils
              cachedBytes = new ByteArrayOutputStream();
              IOUtils.copy(super.getInputStream(), cachedBytes);
          }
          /**
           * 读取缓存的请求正文的输入流
           * <p>
           * 用于根据 缓存输入流 创建一个可返回的
           */
          public static class CachedServletInputStream extends ServletInputStream {
              private final ByteArrayInputStream input;
              public CachedServletInputStream(byte[] buf) {
                  // 从缓存的请求正文创建一个新的输入流
                  input = new ByteArrayInputStream(buf);
              }
              @Override
              public boolean isFinished() {
                  return false;
              }
              @Override
              public boolean isReady() {
                  return false;
              }
              @Override
              public void setReadListener(ReadListener listener) {
              }
              @Override
              public int read() throws IOException {
                  return input.read();
              }
          }
      }

      Filter过滤器(HttpServletRequestInputStreamFilter):

      package com.mry.springboottools.validation;
      import org.springframework.core.annotation.Order;
      import org.springframework.stereotype.Component;
      import javax.servlet.Filter;
      import javax.servlet.FilterChain;
      import javax.servlet.ServletException;
      import javax.servlet.ServletRequest;
      import javax.servlet.ServletResponse;
      import javax.servlet.http.HttpServletRequest;
      import java.io.IOException;
      import static org.springframework.core.Ordered.HIGHEST_PRECEDENCE;
      /**
       * @author
       * @description: 请求流转换为多次读取的请求流 过滤器
       */
      @Component
      @Order(HIGHEST_PRECEDENCE + 1)  // 优先级最高
      public class HttpServletRequestInputStreamFilter implements Filter {
          @Override
          public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
              // 转换为可以多次获取流的request
              HttpServletRequest httpServletRequest = (HttpServletRequest) request;
              InputStreamHttpServletRequestWrapper inputStreamHttpServletRequestWrapper = new InputStreamHttpServletRequestWrapper(httpServletRequest);
              // 放行
              chain.doFilter(inputStreamHttpServletRequestWrapper, response);
          }
      }

      SpringBoot的参数校验validation

      为了减少接口中,业务代码之前的大量冗余的参数校验代码

      SpringBoot-validation提供了优雅的参数校验,入参都是实体类,在实体类字段上加上对应注解,就可以在进入方法之前,进行参数校验,如果参数错误,会抛出错误BindException,是不会进入方法的。

      这种方法,必须要求在接口参数上加注解@Validated或者是@Valid

      但是很多清空下,我们希望在代码中调用某个实体类的校验功能,所以需要如下工具类。

      package com.mry.springboottools.validation;
      import javax.validation.ConstraintViolation;
      import javax.validation.Validation;
      import javax.validation.Validator;
      import java.util.LinkedList;
      import java.util.List;
      import java.util.Set;
      /**
       * @author
       * @description 验证工具类
       */
      public class ValidationUtils {
          private static final Validator VALIDATOR = Validation.buildDefaultValidatorFactory().getValidator();
          /**
           * 验证数据
           * @param object 数据
           */
          public static void validate(Object object) throws CustomizeException {
              Set<ConstraintViolation<Object>> validate = VALIDATOR.validate(object);
              // 验证结果异常
              throwparamException(validate);
          }
          /**
           * 验证数据(分组)
           * @param object 数据
           * @param groups 所在组
           */
          public static void validate(Object object, Class<?> ... groups) throws CZAqRMUCustomizeException {
              Set<ConstraintViolation<Object>&gCZAqRMUt; validate = VALIDATOR.validate(object, groups);
              // 验证结果异常
              throwParamException(validate);
          }
          /**
           * 验证数据中的某个字段(分组)
           * @param object 数据
           * @param propertyName 字段名称
           */
          public static void validate(Object object, String propertyName) throws CustomizeException {
              Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName);
              // 验证结果异常
              throwParamException(validate);
          }
          /**
           * 验证数据中的某个字段(分组)
           * @param object 数据
           * @param propertyName 字段名称
           * @param groups 所在组
           */
          public static void validate(Object object, String propertyName, Class<?> ... groups) throws CustomizeException {
              Set<ConstraintViolation<Object>> validate = VALIDATOR.validateProperty(object, propertyName, groups);
              // 验证结果异常
              throwParamException(validate);
          }
          /**
           * 验证结果异常
           * @param validate 验证结果
           */
          private static void throwParamException(Set<ConstraintViolation<Object>> validate) throws CustomizeException {
              if (validate.size() > 0) {
                  List<String> fieldList = new LinkedList<>();
                  List<String> msgList = new LinkedList<>();
                  for (ConstraintViolation<Object> next : validate) {
                      fieldList.add(next.getPropertyPath().toString());
                      msgList.add(next.getMessage());
                  }
                  throw new ParamException(fieldList, msgList);
              }
          }
      }

      自定义参数异常:

      package com.mry.springboottools.validation;
      import lombok.Getter;
      import org.springframework.util.CollectionUtils;
      import java.util.List;
      /**
       * @author
       * @description 自定义参数异常
       */
      @Getter
      public class ParamException extends CustomizeException {
          private List<String> fieldList;
          private List<String> msgList;
          public ParamException(String message) {
              super(message);
          }
          public ParamException(String message, Throwable cause) {
              super(message, cause);
          }
          public ParamException(List<String> fieldList, List<String> msgList) throws CustomizeException {
              super(generatorMessage(fieldList, msgList));
              this.fieldList = fieldList;
              this.msgList = msgList;
          }
          public ParamException(List<String> fieldList, List<String> msgList, Exception ex) throws CustomizeException {
              super(generatorMessage(fieldList, msgList), ex);
              this.fieldList = fieldList;
              this.msgList = msgList;
          }
          private static String generatorMessage(List<String> fieldList, List<String> msgList) throws CustomizeException {
              if (CollectionUtils.isEmpty(fieldList) || CollectionUtils.isEmpty(msgList) || fieldList.size() != msgList.size()) {
                  return "参数错误";
              }
              StringBuilder message = new StringBuilder();
              for (int i = 0; i < fieldList.size(); i++) {
                  String field = fieldList.get(i);
                  String msg = msgList.get(i);
                  if (i == fieldList.size() - 1) {
                      message.append(field).append(":").append(msg);
                  } else {
                      message.append(field).append(":").append(msg).append(",");
                  }
              }
              return message.toString();
          }
      }

      自定义异常:

      package com.mry.springboottools.validation;
      /**
       * @author
       * @description: 自定义异常
       */
      public class CustomizeException extends Exception {
          public CustomizeException(String message, Throwable cause) {
              super(message, cause);
          }
          public CustomizeException(String message) {
              super(message);
          }
      }

      自定义starter

      自定义starter步骤:

      1.创建工厂,编写功能代码;

      2.声明自动配置类,把需要对外提供的对象创建好,通过配置类统一向外暴露;

      3.在resource目录下准备一个名为spring/spring.factories的文件,以org.springframework.boot.autoconfigure.EnableAutoConfiguration为key,自动配置类为value列表,进行注册;

      RequestBodyAdvice和ResponseBodyAdvice

      1.RequestBodyAdvice是对请求的json串进行处理, 一般使用环境是处理接口参数的自动解密;

      2.ResponseBodyAdvice是对请求响应的json传进行处理,一般用于相应结果的加密;

      功能介绍

      接口数据的时候,返回的是加密之后的数据 接口入参的时候,接收的是解密之后的数据,但是在进入接口之前,加密的会自动解密,取得对应的数据。

      功能细节

      加密解密使用对称加密的AES算法,使用hutool-crypto模块进行实现

      所有的实体类提取一个公共父类,包含属性时间戳,用于加密数据返回之后的实效性,如果超过60分钟,那么其他接口将不进行处理。

      如果接口加了加密注解EncryptionAnnotation,并且返回统一的json数据Result类,则自动对数据进行加密。如果是继承了统一父类RequestBase的数据,自动注入时间戳,确保数据的时效性。

      如果接口加了解密注解DecryptionAnnotation,并且参数使用RequestBody注解标注,传入json使用统一格式RequestData类,并且内容是继承了包含时间长的父类RequestBase,则自动解密,并且转为对应的数据类型。

      功能提供Springboot的starter,实现开箱即用。
