1. 介紹

在我們?nèi)粘５腏ava開發(fā)中，免不了和其他系統(tǒng)的業(yè)務(wù)交互，或者微服務(wù)之間的接口調(diào)用

如果我們想保證數(shù)據(jù)傳輸?shù)陌踩瑢涌诔鰠⒓用埽雲(yún)⒔饷堋?/p>

但是不想寫重復(fù)代碼，我們可以提供一個通用starter，提供通用加密解密功能

2. 前置知識

2.1 hutool-crypto加密解密工具

hutool-crypto提供了很多加密解密工具，包括對稱加密，非對稱加密，摘要加密等等，這不做詳細(xì)介紹。

2.2 request流只能讀取一次的問題

2.2.1 問題：

在接口調(diào)用鏈中，request的請求流只能調(diào)用一次，處理之后，如果之后還需要用到請求流獲取數(shù)據(jù)，就會發(fā)現(xiàn)數(shù)據(jù)為空。

比如使用了filter或者aop在接口處理之前，獲取了request中的數(shù)據(jù)，對參數(shù)進行了校驗，那么之后就不能在獲取request請求流了

2.2.2 解決辦法

繼承HttpServletRequestWrapper，將請求中的流copy一份，復(fù)寫getInputStream和getReader方法供外部使用。每次調(diào)用后的getInputStream方法都是從復(fù)制出來的二進制數(shù)組中進行獲取，這個二進制數(shù)組在對象存在期間一致存在。

使用Filter過濾器，在一開始，替換request為自己定義的可以多次讀取流的request。

這樣就實現(xiàn)了流的重復(fù)獲取

InputStreamHttpServletRequestWrapper

package xyz.hlh.cryptotest.utils;

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;

/**
 * 請求流支持多次獲取
 */
public class InputStreamHttpServletRequestWrapper extends HttpServletRequestWrapper {

    /**
     * 用于緩存輸入流
     */
    private ByteArrayOutputStream cachedBytes;

    public InputStreamHttpServletRequestWrapper(HttpServletRequest request) {
        super(request);
    }

    @Override
    public ServletInputStream getInputStream() throws IOException {
        if (cachedBytes == null) {
            // 首次獲取流時，將流放入 緩存輸入流 中
            cacheInputStream();
        }

        // 從 緩存輸入流 中獲取流并返回
        return new CachedServletInputStream(cachedBytes.toByteArray());
    }

    @Override
    public BufferedReader getReader() throws IOException {
        return new BufferedReader(new InputStreamReader(getInputStream()));
    }

    /**
     * 首次獲取流時，將流放入 緩存輸入流 中
     */
    private void cacheInputStream() throws IOException {
        // 緩存輸入流以便多次讀取。為了方便, 我使用 org.apache.commons IOUtils
        cachedBytes = new ByteArrayOutputStream();
        IOUtils.copy(super.getInputStream(), cachedBytes);
    }

    /**
     * 讀取緩存的請求正文的輸入流
     * <p>
     * 用于根據(jù) 緩存輸入流 創(chuàng)建一個可返回的
     */
    public static class CachedServletInputStream extends ServletInputStream {

        private final ByteArrayInputStream input;

        public CachedServletInputStream(byte[] buf) {
            // 從緩存的請求正文創(chuàng)建一個新的輸入流
            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();
        }
    }

}

HttpServletRequestInputStreamFilter

package xyz.hlh.cryptotest.filter;

import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import xyz.hlh.cryptotest.utils.InputStreamHttpServletRequestWrapper;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;

import javax.servlet.http.HttpServletRequest;

 */
@Component
@Order(HIGHEST_PRECEDENCE + 1)  // 優(yōu)先級最高
public class HttpServletRequestInputStreamFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        // 轉(zhuǎn)換為可以多次獲取流的request
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        InputStreamHttpServletRequestWrapper inputStreamHttpServletRequestWrapper = new InputStreamHttpServletRequestWrapper(httpServletRequest);

        // 放行
        chain.doFilter(inputStreamHttpServletRequestWrapper, response);
    }
}

2.3 SpringBoot的參數(shù)校驗validation

為了減少接口中，業(yè)務(wù)代碼之前的大量冗余的參數(shù)校驗代碼

SpringBoot-validation提供了優(yōu)雅的參數(shù)校驗，入?yún)⒍际菍嶓w類，在實體類字段上加上對應(yīng)注解，就可以在進入方法之前，進行參數(shù)校驗，如果參數(shù)錯誤，會拋出錯誤BindException，是不會進入方法的。

這種方法，必須要求在接口參數(shù)上加注解@Validated或者是@Valid

但是很多清空下，我們希望在代碼中調(diào)用某個實體類的校驗功能，所以需要如下工具類

ParamException

package xyz.hlh.cryptotest.exception;

import lombok.Getter;

import java.util.List;

/**

public class ParamException extends Exception {

    private final List<String> fieldList;
    private final List<String> msgList;

    public ParamException(List<String> fieldList, List<String> msgList) {
        this.fieldList = fieldList;
        this.msgList = msgList;
    }
}

public class ValidationUtils {

    private static final Validator VALIDATOR = Validation.buildDefaultValidatorFactory().getValidator();

    /**

        Set<ConstraintViolation<Object>> validate = VALIDATOR.validate(object);

        // 驗證結(jié)果異常

    public static void validate(Object object, String propertyName, Class<?> ... groups) throws CustomizeException {

        // 驗證結(jié)果異常

    }

    /**

     */
    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);
        }
    }

}

2.5 自定義starter

自定義starter步驟

• 創(chuàng)建工廠，編寫功能代碼
• 聲明自動配置類，把需要對外提供的對象創(chuàng)建好，通過配置類統(tǒng)一向外暴露
• 在resource目錄下準(zhǔn)備一個名為spring/spring.factories的文件，以org.springframework.boot.autoconfigure.EnableAutoConfiguration為key，自動配置類為value列表，進行注冊

2.6 RequestBodyAdvice和ResponseBodyAdvice

• RequestBodyAdvice是對請求的json串進行處理， 一般使用環(huán)境是處理接口參數(shù)的自動解密
• ResponseBodyAdvice是對請求相應(yīng)的jsoin傳進行處理，一般用于相應(yīng)結(jié)果的加密

3. 功能介紹

接口相應(yīng)數(shù)據(jù)的時候，返回的是加密之后的數(shù)據(jù) 接口入?yún)⒌臅r候，接收的是解密之后的數(shù)據(jù)，但是在進入接口之前，會自動解密，取得對應(yīng)的數(shù)據(jù)

4. 功能細(xì)節(jié)

加密解密使用對稱加密的AES算法，使用hutool-crypto模塊進行實現(xiàn)

所有的實體類提取一個公共父類，包含屬性時間戳，用于加密數(shù)據(jù)返回之后的實效性，如果超過60分鐘，那么其他接口將不進行處理。

如果接口加了加密注解EncryptionAnnotation，并且返回統(tǒng)一的json數(shù)據(jù)Result類，則自動對數(shù)據(jù)進行加密。如果是繼承了統(tǒng)一父類RequestBase的數(shù)據(jù)，自動注入時間戳，確保數(shù)據(jù)的時效性

如果接口加了解密注解DecryptionAnnotation，并且參數(shù)使用RequestBody注解標(biāo)注，傳入json使用統(tǒng)一格式RequestData類，并且內(nèi)容是繼承了包含時間長的父類RequestBase，則自動解密，并且轉(zhuǎn)為對應(yīng)的數(shù)據(jù)類型

功能提供Springboot的starter，實現(xiàn)開箱即用
