加解密：将明文转换成一串看不懂的东西，并且还能再转回来

引用jar包：

<dependency>
        <groupId>org.jasypt</groupId>
        <artifactId>jasypt</artifactId>
        <version>1.9.2</version>
    </dependency>

加解密类：

import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
    import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
    import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;
