Springboot + Vue3 使用Rsa加解密示例代码

以下是一个使用Spring Boot和Vue3进行RSA加解密的示例代码：

后端代码（Spring Boot）：

import org.springframework.security.crypto.encrypt.RsaEncryptor;
import org.springframework.security.crypto.encrypt.RsaSecretEncryptor;
import org.springframework.util.Base64Utils;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class RsaController {

    private final RsaEncryptor rsaEncryptor;

    public RsaController(RsaEncryptor rsaEncryptor) {
        this.rsaEncryptor = rsaEncryptor;
    }

    @PostMapping("/encrypt")
    public String encrypt(@RequestBody String plainText) {
        byte[] encryptedBytes = rsaEncryptor.encrypt(plainText.getBytes());
        return Base64Utils.encodeToString(encryptedBytes);
    }

    @PostMapping("/decrypt")
    public String decrypt(@RequestBody String encryptedText) {
        byte[] encryptedBytes = Base64Utils.decodeFromString(encryptedText);
        byte[] decryptedBytes = rsaEncryptor.decrypt(encryptedBytes);
        return new String(decryptedBytes);
    }
}

前端代码（Vue3）：

<template>
  <div>
    <input v-model="plainText" type="text" placeholder="Plain Text" />
    <button @click="encrypt">Encrypt</button>
    <input v-model="encryptedText" type="text" placeholder="Encrypted Text" />
    <button @click="decrypt">Decrypt</button>
    <input v-model="decryptedText" type="text" placeholder="Decrypted Text" />
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      plainText: '',
      encryptedText: '',
      decryptedText: '',
    };
  },
  methods: {
    async encrypt() {
      try {
        const response = await axios.post('/encrypt', this.plainText);
        this.encryptedText = response.data;
      } catch (error) {
        console.error(error);
      }
    },
    async decrypt() {
      try {
        const response = await axios.post('/decrypt', this.encryptedText);
        this.decryptedText = response.data;
      } catch (error) {
        console.error(error);
      }
    },
  },
};
</script>

在上述代码中，后端使用了Spring Boot的RsaEncryptor来进行RSA加密和解密操作。前端使用了Vue3框架，并使用axios库发送加密和解密请求。

请注意，上述代码仅提供了一个基本的示例，实际应用中需要根据具体的需求进行适当的修改和调整
