shiro的加密 深入浅出

密码的比对:

通过 AuthenticatingRealm 的credentialsMatcher 属性来进行的密码的比对!

 替换当前 Realm 的 credentialsMatcher 属性. 直接使用 HashedCredentialsMatcher 对象, 并设置加密算法即可. 

配置application-shiro.xml

   <!--     3. 配置 Realm     3.1 直接配置实现了 org.apache.shiro.realm.Realm 接口的 bean     <bean id="jdbcRealm" class="com.zhongyou.shiro.realms.ShiroRealm"></bean>    -->         <bean id="jdbcRealm" class="com.zhongyou.shiro.realms.ShiroRealm">    <property name="credentialsMatcher">    <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">    <property name="hashAlgorithmName" value="MD5"></property>    <property name="hashIterations" value="1024"></property>    </bean>    </property>    </bean>

1. 如何把一个字符串加密为 MD5 

public static void main(String[] args) {String hashAlgorithmName = "MD5";Object credentials = "123456";//Object salt = ByteSource.Util.bytes("user");

Object salt = null；int hashIterations = 1024;Object result = new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations);System.out.println(result);}
