demo1主要完成以下测试，在web环境下，输入用户名和密码，去数据库找对应的信息，如果有，转到成功页面，如果失败转到错误页面。用到的技术主要有spring，springmvc，shiro。
一、在spring的配置文件中，生成realme的类文件。在这个类中，继承自AuthenticatingRealm，实现查询数据库的功能，然后返回SimpleAuthenticationInfo类型的信息。这个地方与springmvc中映射登录的地方对应。
二、在登录的地方，用注解接受参数，接受用户名和密码，然后生成Subject对象，然后用用户名和密码，生成token，用subject对象的login（token）尝试登录，如果登录成功，转到成功页面，否则去失败页面。说的简单一点，一个是realme的类，一个是webmvc的login（token）尝试，这两者的联系，是由框架完成。
以下为代码

ehcache的配置文件，默认从别的地方拷贝过来的，当时没有修改
<ehcache> <!-- Sets the path to the directory where cache .data files are created. If the path is a Java System Property it is replaced by its value in the running VM. The following properties are translated: user.home - User's home directory user.dir - User's current working directory java.io.tmpdir - Default temp file path --> <diskStore path="java.io.tmpdir/shiro-ehcache"/> <!--Default Cache configuration. These will applied to caches programmatically created through the CacheManager. --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" /> <!-- We want eternal="true" and no timeToIdle or timeToLive settings because Shiro manages session expirations explicitly. If we set it to false and then set corresponding timeToIdle and timeToLive properties, ehcache would evict sessions without Shiro's knowledge, which would cause many problems diskPersistent=true since we want an enterprise session management feature - ability to use sessions after even after a JVM restart. --> <cache name="shiro-activeSessionCache" maxElementsInMemory="10000" overflowToDisk="true" eternal="true" timeToLiveSeconds="0" timeToIdleSeconds="0" diskPersistent="true" diskExpiryThreadIntervalSeconds="600"/> <cache name="org.apache.shiro.realm.text.PropertiesRealm-0-accounts" maxElementsInMemory="1000" eternal="true" overflowToDisk="true"/> </ehcache>
本例子中，对于密码，没有加密，若加密，需要
在spring的配置文件中，加入在jdbcRealm中修改为
<bean id="jdbcRealm" class="cn.taotao.bean.shiroRealm"> <property name="credentialsMatcher"> <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher"> <property name="hashAlgorithmName" value="MD5"></property> <property name="hashIterations" value="1000"></property> </bean> </property> </bean>
可以用SimpleHash的api看到密码
SimpleHash sh = new SimpleHash("MD5",password,null,1000);
