生效

如果是為spring boot項目的配置文件加密，則無需額外配置，啟動類上的@SpringBootApplication自動會將其注入程序，使其生效。

作用域

指定配置文件的作用域，其他配置文件不受jasypt影響

@Configuration
@EncryptablePropertySources({
    @EncryptablePropertySource("classpath:sentinel-1.properties"),                          
    @EncryptablePropertySource("classpath:sentinel-2.properties")
    })

應(yīng)用
