Spring Boot集成Jasypt安全框架

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");
EncryptablePropertySourcesPlaceholderConfigurer
configurer = 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=false
username: root
password: ${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。
