This code includes a method that decrypts a given cipher text. It checks if the cipher text matches a specific pattern and if it does, it uses a public key to decrypt it. The decrypted text is then returned. In the configuration file, the password and public key are specified using the ENC(xxx) format. After the decryption process, there is no further action.

Actually, decryption is already built-in.

com.baomidou.dynamic.datasource.spring.boot.autoconfigure.DataSourceProperty

	private String decrypt(String cipherText) {
        if (StringUtils.hasText(cipherText)) {
            Matcher matcher = ENC_PATTERN.matcher(cipherText);
            if (matcher.find()) {
                try {
                    return CryptoUtils.decrypt(this.publicKey, matcher.group(1));
                } catch (Exception var4) {
                    log.error("DynamicDataSourceProperties.decrypt error ", var4);
                }
            }
        }

        return cipherText;
    }

After detecting the format ENC(xxx), it will decrypt.

In the configuration file, you only need to add:

spring.datasource.dynamic.datasource.gesoft_pcp.password=ENC(xxxxx)
spring.datasource.dynamic.datasource.gesoft_pcp.public-key=xxxxxx

That's all, there is no more.
