Spring 中的.properties 属性（jdbc.password）加密

1、复写processProperties方法实现 

package com.*.*;import java.util.Properties;import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer; public class PropertyPlaceholderConfigurerTest extends PropertyPlaceholderConfigurer {protected void processProperties(ConfigurableListableBeanFactory beanFactory, Properties props) throws BeansException { String password = props.getProperty("jdbc.password"); String username = props.getProperty("jdbc.username"); try {if (password != null) { //解密jdbc.password属性值，并重新设置 //Crypt.decrypt：自己编写的对应的解密方法（本文采用aes算法，aes网上有很多就不写出来了）props.setProperty("jdbc.password", Crypt.decrypt(password));} if (username != null) { props.setProperty("jdbc.username", Crypt.decrypt(username));} super.processProperties(beanFactory, props);} catch (Exception e) {e.printStackTrace();} }
}

2、xml配置

<!-- 不加密时候使用使用spring自带的 -->

<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:jdbc.properties</value>   <value>classpath:roles.properties</value></list></property>
</bean>

<!-- 加密时候使用自己复写过的 -->

<bean id="propertyConfigurer"
class="com.*.*.PropertyPlaceholderConfigurerTest"><property name="locations"><list><value>classpath:jdbc.properties</value><value>classpath:roles.properties</value></list></property>
</bean>

jdbc.username=F4B2DEB6F8FA201C5783A959CE1C3180
jdbc.password=F4B2DEB6F8FA201C5783A959CE1C3180
