Spring4 中使用 jasypt 加密数据密码

1.加载类jar
<dependency>
        <groupId>org.jasypt</groupId>
        <artifactId>jasypt</artifactId>
        <version>1.9.2</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.jasypt/jasypt-spring31 -->
    <dependency>
        <groupId>org.jasypt</groupId>
        <artifactId>jasypt-spring31</artifactId>
        <version>1.9.2</version>
    </dependency>

2.使用工具生成加密后的密码

package gjp.test;

import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig;

/**
* Created by gjp on 2017/7/5.
* 把密文放到配置文件中的时候要注意：
* ENC(密文)
*/
public class ConfigEncryptUtils {

    /**jasypt 加密算法
     * Pwd.
     */
    public static void enpwd(){
        //加密工具
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        //加密配置
        EnvironmentStringPBEConfig config = new EnvironmentStringPBEConfig();
        config.setAlgorithm("PBEWithMD5AndDES");
        //自己在用的时候更改此密码
        config.setPassword("123456");
        //应用配置
        encryptor.setConfig(config);
        String plaintext="shiro123";
        //加密
        String ciphertext=encryptor.encrypt(plaintext);
        System.out.println(plaintext + " : " + ciphertext);
    }


    /**jasypt 解密算法
     * De pwd.
     */
    public static void dePwd(){

        //加密工具
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        //加密配置
        EnvironmentStringPBEConfig config = new EnvironmentStringPBEConfig();
        config.setAlgorithm("PBEWithMD5AndDES");
        //自己在用的时候更改此密码
        config.setPassword("123456");
        //应用配置
        encryptor.setConfig(config);
        String ciphertext="PovZgl9pg6IXlalIyavYG6HQBq4NyM96";
        //解密
        String plaintext=encryptor.decrypt(ciphertext);
        System.out.println(ciphertext + " : " + plaintext);
    }
    public static void main(String[] args){


        ConfigEncryptUtils.enpwd();
    }
}


生成加密后的密码： rgsjYM2QG/lSuSUSuIvlXyD51NfWaEWb

3.配置文件： jdbcOracle_test.properties

#jdbc settings
jdbc.driverUrl=jdbc:oracle:thin:@192.168.6.24:1521:YUNBOCE
jdbc.username=shiro
jdbc.password=ENC(rgsjYM2QG/lSuSUSuIvlXyD51NfWaEWb)
#shiro123
jdbc.driver=oracle.jdbc.OracleDriver
#注意加密后的密码一定要使用ENC()

配置spring
