1、What is Apache Shiro? <--返回目录

　　10 Minute Tutorial on Apache Shiro：http://shiro.apache.org/10-minute-tutorial.html

　　Apache Shiro is a powerful and easy to use Java security framework that offers developers an intuitive yet comprehensive solution to authentication, authorization, cryptography, and session management.

　　Shiro：java安全框架，提供认证、授权、加密和回话管理。

　　获取当前用户：

Subject currentUser = SecurityUtils.getSubject();

　　获取用户session:

Session session = currentUser.getSession();
session.setAttribute( "someKey", "aValue" );

　　用户认证：

if ( !currentUser.isAuthenticated() ) {
    //collect user principals and credentials in a gui specific manner
    //such as username/password html form, X509 certificate, OpenID, etc.
    //We'll use the username/password example here since it is the most common.
    UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
    //this is all you have to do to support 'remember me' (no config - built in!):
    token.setRememberMe(true);
    currentUser.login(token);
}

　　登陆失败的处理：

try {
    currentUser.login( token );
    //if no exception, that's it, we're done!
} catch ( UnknownAccountException uae ) {
    //username wasn't in the system, show them an error message?
} catch ( IncorrectCredentialsException ice ) {
    //password didn't match, try again?
} catch ( LockedAccountException lae ) {
    //account for that username is locked - can't login.  Show them a message?
}
    ... more types exceptions to check if you want ...
} catch ( AuthenticationException ae ) {
    //unexpected condition - error?
}

　　获取登陆用户的信息，比如用户名：

currentUser.getPrincipal()

　　判断登陆用户是否有指定角色或权限：

if ( currentUser.hasRole( "schwartz" ) ) {
    log.info("May the Schwartz be with you!" );
} else {
    log.info( "Hello, mere mortal." );
}

if ( currentUser.isPermitted( "lightsaber:weild" ) ) {
    log.info("You may use a lightsaber ring.  Use it wisely.");
} else {
    log.info("Sorry, lightsaber rings are for schwartz masters only.");
}

　　用户退出：

currentUser.logout();

2、shiro demo: 身份认证使用textRealm <--返回目录

　　依赖：

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.12</version>
</dependency>

　　在classpath新建配置文件shiro.ini

[users]
java=123456

　　测试类

package com.oy;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.config.IniSecurityManagerFactory;

import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;

public class HelleWorld {

    public static void main(String[] args) {
        // 读取配置文件，初始化SecurityManager工厂
        Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:shiro.ini");
        // 获取securityManager实例
        SecurityManager securityManager=factory.getInstance();
        // 把securityManager实例绑定到SecurityUtils
        SecurityUtils.setSecurityManager(securityManager);
        // 得到当前执行的用户
        Subject currentUser=SecurityUtils.getSubject();
        // 创建token令牌，用户名/密码
        UsernamePasswordToken token=new UsernamePasswordToken("java", "123456");
        try{
            // 身份认证
            currentUser.login(token);    
            System.out.println("身份认证成功！");
        }catch(AuthenticationException e){
            e.printStackTrace();
            System.out.println("身份认证失败！");
        }
        // 退出
