java：shiro（认证，赋予角色，授权...）
1.shiro（权限框架（认证，赋予角色，授权...））：
readme.txt（运行机制）：
1.从jsp的form中的action属性跳转到springmvc的Handler中(controller)
2.首先获取Subject，因为securityManager在applicationContext.xml中配置过了，所以可以直接
通过Subject currentUser = SecurityUtils.getSubject();
3.开始认证
首先把账号和密码封装进UsernamePasswordToken中，然后调用subject的login(UsernamePasswordToken);
4.真正的认证开始(需要和数据库进行交互)
select * from table where username="zhangsan"
select * from table where username="zhangsan" and passowrd="123456"
4.1 通过username先查询该登录用户是否存在，如果不存在就抛出异常
4.2 如果登录用户存在，再次检验是否可以正常使用，如果不能正常使用就抛出异常
4.3 匹配密码
5.密码匹配流程
5.1.从前端获取用户输入的密码
5.2.从数据库中通过用户名查询密码
5.3.把查询出的密码SimpleAuthenticationInfo
5.4.shiro会通过SimpleCredentialsMatcher.class中doCredentialsMatch()进行匹配从前端传递的密码和从数据库中查询的密码是否一致
5.4.1.doCredentialsMatch()会重写equals()来进行匹配if("123456".equals(user.getPassword()))
5.4.2.该方法中需要两个参数
AuthenticationToken(I)-实现类->UsernamePasswordToken(封装了前端传递的用户名和密码)
用户名和密码
AuthenticationInfo(I)-被继承->SaltedAuthenticationInfo(I)-实现类->SimpleAuthenticationInfo(username, user.getPassword(), getName())
username:获取密码使用
user.getPassword():需要和前端进行匹配
getName()-->realmName(ShiroRealm2)
为授权做准备
6.密码加密
6.1.因为密码为明文，存入数据库中和项目运行过程中会在开发者工具中出现，所以存在安全隐患问题(如果用户密码遭遇泄漏，并且牵扯到金钱问题，发开公司将会承担用户的一切损失)
6.2.进行为密码的加密
shiro会在配置文件中指定加密方式(.ini配置文件，和spring整合以后会在applicationContext.xml中id="jdbcRealm")
最终密码匹配是在SimpleCredentialsMatcher.class进行-->实现CredentialsMatcher(I)
SimpleCredentialsMatcher.class下有一个子类，一旦使用指定shiro用MD5对密码进行加密的配置以后，密码匹配会在 Md5CredentialsMatcher.class中进行
Md5CredentialsMatcher.class已经将来被废弃，所以
since 1.1 - use the HashedCredentialsMatcher directly and set its
最终对密码进行加密和匹配HashedCredentialsMatcher进行实现
如何对明文密码进行加密
6.2.1.从前端获取到用户输入的密码-->通过doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info)进行密码比对
当进入方法的第一个参数时：AuthenticationToken-->首先会到org.apache.shiro.authc.credential.HashedCredentialsMatcher进行加密-->返回被加密过的密码
-->返回给AuthenticationToken token
-->进行对比AuthenticationToken token和AuthenticationInfo info(从数据库查询出的密码进行对比)
shiro使用哪一种方式对密码进行明文加密(MD5)
6.2.2.<!-- 指定密码的加密算法为MD5 -->
<property name="credentialsMatcher">
<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<!-- hashAlgorithmName:指定了shiro的加密方式，默认就是MD5，如果需要使用其他的加密方式，就必须自定义实现 -->
<property name="hashAlgorithmName" value="MD5"></property>
<!--指定使用MD5加密的次数-->
<property name="hashIterations" value="1024"></property>
</bean>
</property>
开启shiro的加密方式
6.2.3.因为如果两个用户的密码相同，MD5加密后存入数据库也相同，需要使用"颜值"加密
user.getPassword()：从数据库中查询出的密码
ByteSource.Util.bytes("1"):颜值
ByteSource类型(I)
里面会有一个内部实现类,可以构造出ByteSource实例对象
This is slightly nicer than needing to know the implementation class to use.
如果获取到颜值？
ByteSource.Utils.bytes("字符串类型");返回值就是颜值所需要的类型(ByteSource)
使用new SimpleAuthenticationInfo(username, user.getPassword(), ByteSource.Util.bytes("1"), getName());
7.授权
7.1.因为AuthenticatingRealm只做认证功能，那么授权在同一个class中无法处理
7.2.授权需要使用到的class是AuthenticatingRealm一个子类AuthorizingRealm
AuthorizingRealm.class既可以进行认证功能，也可以进行授权的功能
