Jasypt安全框架提供了Spring的集成,主要是实现
PlaceholderConfigurerSupport类或者其子类。
在Sring 3.1之后,则推荐使用PropertySourcesPlaceholderConfigurer类作为属性替换配置类,这里Spring集成Jasypt则使用Jasypt对属性替换配置类的实现。EncryptablePropertySourcesPlaceholderConfigurer。
在Spring中集成比较容易,而且Jasypt官方也给出了配置Bean的方式和使用Jasypt标签的XML方式,而Spring boot集成就稍微有点不一样,需要创建一个自动配置类,并且创建一个注入PlaceholderConfigurerSupport的jasypt实现了的Bean .
下面是一个使用示例:
import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.jasypt.spring31.properties.EncryptablePropertySourcesPlaceholderConfigurer;
import org.springframework.boot.autoconfigure.AutoConfigureOrder;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.condition.SearchStrategy;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.core.Ordered;
import org.springframework.core.io.ClassPathResource;/*** Author : secondriver* Date : 2016/5/26*/
@Configuration
@AutoConfigureOrder(Ordered.HIGHEST_PRECEDENCE)
public class EncryptPropertyPlaceholderAutoConfiguration {private static final String SECURITY_PROPERTIES_FILE = "security.properties";@Bean@ConditionalOnMissingBean(search = SearchStrategy.CURRENT)public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();encryptor.setAlgorithm(StandardPBEByteEncryptor.DEFAULT_ALGORITHM);encryptor.setPassword("security");EncryptablePropertySourcesPlaceholderConfigurerconfigurer = new EncryptablePropertySourcesPlaceholderConfigurer(encryptor);configurer.setLocation(new ClassPathResource(SECURITY_PROPERTIES_FILE));return configurer;}
}
配置文件的写入和Spring XML的基本类似。application.yml相当于applicationContext.xml,security.properties就是要进行属性替换的配置文件。
application.yml:
spring:datasource:url: jdbc:mysql://localhost:3306/abc?useSSL=falseusername: rootpassword: ${jdbc.password}
security.properties:
jdbc.password=ENC(jWgGELCkuxRuCI2Aqa6cF9VCxYpuKEZr)
创建数据源的时候在使用属性参数时,会对ENC()中的内容进行解密,达到认证成功,创建数据源完成。
