1. 介紹

在我們?nèi)粘５腏ava開發(fā)中蹋半，免不了和其他系統(tǒng)的業(yè)務(wù)交互猎醇，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?duì)接口出參加密火焰，入?yún)⒔饷堋?/p>

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

2. 前置知識(shí)

2.1 hutool-crypto加密解密工具

hutool-crypto提供了很多加密解密工具荐健，包括對(duì)稱加密，非對(duì)稱加密琳袄，摘要加密等等江场，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)用鏈中窖逗，request的請(qǐng)求流只能調(diào)用一次址否，處理之后，如果之后還需要用到請(qǐng)求流獲取數(shù)據(jù)碎紊，就會(huì)發(fā)現(xiàn)數(shù)據(jù)為空佑附。

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)仗考，對(duì)參數(shù)進(jìn)行了校驗(yàn)音同，那么之后就不能在獲取request請(qǐng)求流了

2.2.2 解決辦法

繼承HttpServletRequestWrapper，將請(qǐng)求中的流copy一份秃嗜，復(fù)寫getInputStream和getReader方法供外部使用权均。每次調(diào)用后的getInputStream方法都是從復(fù)制出來的二進(jìn)制數(shù)組中進(jìn)行獲取，這個(gè)二進(jìn)制數(shù)組在對(duì)象存在期間一致存在锅锨。

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

這樣就實(shí)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;

/**

 */
public class InputStreamHttpServletRequestWrapper extends HttpServletRequestWrapper {

    /**

     */
    private ByteArrayOutputStream cachedBytes;

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

    @Override
    public ServletInputStream getInputStream() throws IOException {
        if (cachedBytes == null) {
            // 首次獲取流時(shí)必指，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(shí)，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恕洲。為了方便, 我使用 org.apache.commons IOUtils
        cachedBytes = new ByteArrayOutputStream();
        IOUtils.copy(super.getInputStream(), cachedBytes);
    }

    /**

     */
    public static class CachedServletInputStream extends ServletInputStream {

        private final ByteArrayInputStream input;

        public CachedServletInputStream(byte[] buf) {
            // 從緩存的請(qǐng)求正文創(chuàng)建一個(gè)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();
        }
    }

}

2.3 SpringBoot的參數(shù)校驗(yàn)validation

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

SpringBoot-validation提供了優(yōu)雅的參數(shù)校驗(yàn)梅割，入?yún)⒍际菍?shí)體類，在實(shí)體類字段上加上對(duì)應(yīng)注解谱邪，就可以在進(jìn)入方法之前炮捧，進(jìn)行參數(shù)校驗(yàn)，如果參數(shù)錯(cuò)誤惦银，會(huì)拋出錯(cuò)誤BindException，是不會(huì)進(jìn)入方法的末誓。

這種方法扯俱，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(gè)實(shí)體類的校驗(yàn)功能喇澡，所以需要如下工具類

ParamException

package xyz.hlh.cryptotest.exception;

import lombok.Getter;

2.4 自定義starter

自定義starter步驟

• 創(chuàng)建工廠迅栅，編寫功能代碼

• 聲明自動(dòng)配置類，把需要對(duì)外提供的對(duì)象創(chuàng)建好晴玖，通過配置類統(tǒng)一向外暴露

• 在resource目錄下準(zhǔn)備一個(gè)名為spring/spring.factories的文件读存，以org.springframework.boot.autoconfigure.EnableAutoConfiguration為key，自動(dòng)配置類為value列表呕屎，進(jìn)行注冊(cè)

2.5 RequestBodyAdvice和ResponseBodyAdvice

• RequestBodyAdvice是對(duì)請(qǐng)求的json串進(jìn)行處理让簿， 一般使用環(huán)境是處理接口參數(shù)的自動(dòng)解密

• ResponseBodyAdvice是對(duì)請(qǐng)求相應(yīng)的jsoin傳進(jìn)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(shí)候秀睛，返回的是加密之后的數(shù)據(jù) 接口入?yún)⒌臅r(shí)候尔当，接收的是解密之后的數(shù)據(jù)，但是在進(jìn)入接口之前蹂安，會(huì)自動(dòng)解密椭迎，取得對(duì)應(yīng)的數(shù)據(jù)

4. 功能細(xì)節(jié)

加密解密使用對(duì)稱加密的AES算法，使用hutool-crypto模塊進(jìn)行實(shí)現(xiàn)

所有的實(shí)體類提取一個(gè)公共父類田盈，包含屬性時(shí)間戳畜号，用于加密數(shù)據(jù)返回之后的實(shí)效性，如果超過60分鐘允瞧，那么其他接口將不進(jìn)行處理简软。

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類瓷式，則自動(dòng)對(duì)數(shù)據(jù)進(jìn)行加密替饿。如果是繼承了統(tǒng)一父類RequestBase的數(shù)據(jù)，自動(dòng)注入時(shí)間戳贸典，確保數(shù)據(jù)的時(shí)效性

如果接口加了解密注解DecryptionAnnotation视卢，并且參數(shù)使用RequestBody注解標(biāo)注，傳入json使用統(tǒng)一格式RequestData類廊驼，并且內(nèi)容是繼承了包含時(shí)間長(zhǎng)的父類RequestBase据过，則自動(dòng)解密惋砂，并且轉(zhuǎn)為對(duì)應(yīng)的數(shù)據(jù)類型

功能提供Springboot的starter，實(shí)現(xiàn)開箱即用
