报错如下：

 原因：如图，富文本路径中存在 / 字符，导致上传出错。

 解决方案：将富文本框内容在前端进行加密，后端再解密。

前端：

安装 crypto-js 插件

npm install crypto-js

创建工具类 :在 src 目录下的  utils  中创建asc.js

import CryptoJS from 'crypto-js'// 需要和后端一致
const KEY = CryptoJS.enc.Utf8.parse('wenhePiCloudSecre');
const IV = CryptoJS.enc.Utf8.parse('wenhePiCloudSecre');export default {/*** 加密* @param {*} word* @param {*} keyStr* @param {*} ivStr*/encrypt (word, keyStr, ivStr) {let key = KEY;let iv = IV;if (keyStr) {key = CryptoJS.enc.Utf8.parse(keyStr);iv = CryptoJS.enc.Utf8.parse(ivStr);}let srcs = CryptoJS.enc.Utf8.parse(word);var encrypted = CryptoJS.AES.encrypt(srcs, key, {iv: iv,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.ZeroPadding});return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);},/*** 解密* @param {*} word* @param {*} keyStr* @param {*} ivStr*/decrypt (word, keyStr, ivStr) {let key = KEY;let iv = IV;if (keyStr) {key = CryptoJS.enc.Utf8.parse(keyStr);iv = CryptoJS.enc.Utf8.parse(ivStr);}let base64 = CryptoJS.enc.Base64.parse(word);let src = CryptoJS.enc.Base64.stringify(base64);let decrypt = CryptoJS.AES.decrypt(src, key, {iv: iv,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.ZeroPadding});let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);return decryptedStr.toString();}
}

使用：引入函数，使用函数

asc.encrypt(data)

后端：

 maven中引入包：

            <dependency><groupId>org.bouncycastle</groupId><artifactId>bcprov-jdk15on</artifactId><version>1.60/version></dependency>

创建工具类：

package com.ruoyi.common.utils;import org.apache.commons.codec.binary.Base64;import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;/*** @author root*/
public class SecretUtil {/**** key和iv值需要和前端一致*/public static final String KEY = "wenhePiCloudSecre";public static final String IV = "wenhePiCloudSecre";/*** 加密方法** @param data 要加密的数据* @param key  加密key* @param iv   加密iv* @return 加密的结果*/public static String encrypt(String data, String key, String iv) {try {//"算法/模式/补码方式"NoPadding PkcsPaddingCipher cipher = Cipher.getInstance("AES/CBC/NoPadding");int blockSize = cipher.getBlockSize();byte[] dataBytes = data.getBytes();int plaintextLength = dataBytes.length;if (plaintextLength % blockSize != 0) {plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));}byte[] plaintext = new byte[plaintextLength];System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length);SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec);byte[] encrypted = cipher.doFinal(plaintext);return new Base64().encodeToString(encrypted);} catch (Exception e) {e.printStackTrace();return null;}}/*** 解密方法** @param data 要解密的数据* @param key  解密key* @param iv   解密iv* @return 解密的结果*/public static String desEncrypt(String data, String key, String iv) {try {byte[] encrypted1 = new Base64().decode(data);Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");SecretKeySpec keySpec = new SecretKeySpec(key.getBytes(), "AES");IvParameterSpec ivSpec = new IvParameterSpec(iv.getBytes());cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);byte[] original = cipher.doFinal(encrypted1);return new String(original).trim();} catch (Exception e) {e.printStackTrace();return null;}}
}

使用：

 object.setDocContent(SecretUtil.desEncrypt(object.getDocContent(),SecretUtil.KEY,SecretUtil.IV));

搞定～
