1.pom文件增加依赖
<dependency>
<groupId>com.github.ulisesbocchio</groupId>
<artifactId>jasypt-spring-boot-starter</artifactId>
<version>3.0.5</version>
</dependency>
2.修改启动类增加StringEncryptor实现
jasypt密码可以放到配置文件或者启动命令中，与其这样不如直接写到代码里
@Primary
@Bean("jasyptStringEncryptor")
public StringEncryptor stringEncryptor() {
PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
SimpleStringPBEConfig config = new SimpleStringPBEConfig();
config.setPassword("xxxx");//这里改成你的密码
config.setAlgorithm("PBEWITHHMACSHA512ANDAES_256");
config.setKeyObtentionIterations("1000");
config.setPoolSize("1");
config.setProviderName("SunJCE");
config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
config.setIvGeneratorClassName("org.jasypt.iv.RandomIvGenerator");
config.setStringOutputType("base64");
encryptor.setConfig(config);
return encryptor;
}
注意：上面的@Primary 注解必须加上，覆盖默认实现。
3.本地写一个加密类，对你要加密的敏感信息加密
import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;
public class JasyptTest {
public static void main(String[] args) {
PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
SimpleStringPBEConfig config = new SimpleStringPBEConfig();
config.setPassword("xxxx");//改成你的密码
config.setAlgorithm("PBEWITHHMACSHA512ANDAES_256");
config.setKeyObtentionIterations("1000");
config.setPoolSize("1");
config.setProviderName("SunJCE");
config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
config.setIvGeneratorClassName("org.jasypt.iv.RandomIvGenerator");
config.setStringOutputType("base64");
encryptor.setConfig(config);
String originStr = "xxxx" ;//原始字符串
String encStr = encryptor.encrypt(originStr);
System.out.println("originStr encrypt is {}"+ encStr);//加密后的字符串，这个贴到配置文件中
System.out.println("originStr is {}"+ encryptor.decrypt(encStr));//验证一下解密
}
}
4.修改配置文件
将加密后的信息用前面用 ENC( ) 包起来
例如：
原始配置：
spring.datascoure.password=yourpassword
改成：
spring.datascoure.password=ENC(JL2t1CZpj+cTQ30IFKu0lkoZCVpYbVIhLm1MRbBpaNI])
(完)
