Shiro学习记录

1.添加依赖包：

       <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core -->
		<dependency>
		    <groupId>org.apache.shiro</groupId>
		    <artifactId>shiro-core</artifactId>
		    <version>1.4.0</version>
		</dependency>
		<dependency>
		  <groupId>org.apache.shiro</groupId>
		  <artifactId>shiro-web</artifactId>
		  <version>1.3.2</version>
		</dependency>
  		<!-- https://mvnrepository.com/artifact/commons-logging/commons-logging -->
		<dependency>
		    <groupId>commons-logging</groupId>
		    <artifactId>commons-logging</artifactId>
		    <version>1.2</version>
		</dependency>
		
		<dependency>  
		    <groupId>org.slf4j</groupId>  
		    <artifactId>slf4j-log4j12</artifactId>  
		    <version>1.7.5</version>  
		</dependency>  
  		
  		<dependency>

		<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
		<dependency>
		    <groupId>org.apache.commons</groupId>

		<dependency>
		    <groupId>commons-codec</groupId>
		    <artifactId>commons-codec</artifactId>
		    <version>1.9</version>
		</dependency>

2.添加shiro.ini配置(放在src目录下，mavan环境放置在src/main/resource目录下)

[main]
#realm
#自定义Realm
myRealm = com.jsaas.core.security.ShiroDbRealm
securityManager.realm = $myRealm

#配置shiro的密码验证方式为盐加密   也可以通过ShiroDbRealm 中 setCredentialsMatcher方法指定自定义的密码验证方式
credentialsMatcher=org.apache.shiro.authc.credential.HashedCredentialsMatcher
credentialsMatcher.hashAlgorithmName=SHA-1
credentialsMatcher.hashIterations=1024
credentialsMatcher.storedCredentialsHexEncoded=true
myRealm.credentialsMatcher=$credentialsMatcher

#没有登录的用户请求需要登录的页面时自动跳转到登录页面，不是必须的属性，不输入地址的话会自动寻找项目web项目的根目录下的”/login.jsp”
shiro.loginUrl = /tologin
#登录成功默认跳转页面，不配置则跳转至”/”。如果登陆前点击的一个需要登录的页面，则在登录自动跳转到那个需要登录的页面。不跳转到此。
shiro.successUrl = /sys/user/successUrl
#没有权限默认跳转的页面。
shiro.unauthorizedUrl = /403

#cache
shiroCacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
shiroCacheManager.cacheManagerConfigFile = classpath:ehcache.xml
securityManager.cacheManager = $shiroCacheManager


#session
#sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO
sessionDAO = com.jsaas.core.security.OnlineSessionDao
sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
sessionDAO.activeSessionsCacheName = shiro-activeSessionCache
sessionManager.sessionDAO = $sessionDAO
securityManager.sessionManager = $sessionManager
securityManager.sessionManager.globalSessionTimeout = 360000

[urls]
/login/** = anon
/user/** = anon
/** = authc

配置web.xml文件

<!-- 配置apache shiro监听 -->
	<listener>
		<listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
	</listener>
	
	<!-- 配置apache shiro过滤器 -->
	<filter>
		<filter-name>ShiroFilter</filter-name>
		<filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
	</filter>

3.ShiroDbRealm类

package com.jsaas.core.security;

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.credential.CredentialsMatcher;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;

import com.jfinal.kit.Kv;
import com.jfinal.kit.StrKit;
import com.jfinal.plugin.activerecord.Db;
import com.jfinal.plugin.activerecord.SqlPara;
import com.jsaas.model.User;
import com.jsaas.utils.Encodes;
import com.jsaas.utils.MyUtils;

/**   
 * @Title: ShiroDbRealm.java 
 * @Package com.jsaas.core.security 
 * @Description: TODO(shiro) 
 * @author tuozq 
 * @date 2017年11月3日 下午4:37:20 
 * @version V1.0   
 */
public class ShiroDbRealm extends AuthorizingRealm {
	

	/*@Override
	public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
		// TODO Auto-generated method stub
		//自定义密码验证类  集成SimpleCredentialsMatcher 实现doCredentialsMatch方法
		super.setCredentialsMatcher(new MyCredentialsMatcher());
	}*/

	/**
	 * 登录认证
	 * 身份认证
	 *  SecurityUtils.getSubject().login(token) 时调用此方法
	 */
	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
		// TODO Auto-generated method stub
		CaptchaUsernamePasswordToken authcToken = (CaptchaUsernamePasswordToken) token;

		if (authcToken.getUsername()==null||StrKit.isBlank(authcToken.getUsername())) {
			throw new AuthenticationException("用户名不可以为空");
		}

		String account = authcToken.getUsername();
		SqlPara sqlPara = Db.getSqlPara("user.findUser", Kv.by("account", account));
		User user = User.dao.findFirst(sqlPara);
		if(MyUtils.isNotNull(user)){
			byte[] salt = Encodes.decodeHex(user.getSalt());
			//UserPrincipal为自定义用户身份信息，登录成功后可以通过SecurityUtils.getSubject().getPrincipal()获取身份信息
			return new SimpleAuthenticationInfo(new UserPrincipal(user), user.getPassword(), ByteSource.Util.bytes(salt), getName());
		}

		return null;
	}

	/**
	 * 此方法调用  hasRole,hasPermission的时候才会进行回调.
	 *
	 * 权限信息.(授权):
	 * 1、如果用户正常退出，缓存自动清空；
	 * 2、如果用户非正常退出，缓存自动清空；
	 * 3、如果我们修改了用户的权限，而用户不退出系统，修改的权限无法立即生效。
	 * :Authorization 是授权访问控制，用于对用户进行的操作授权，证明该用户是否允许进行当前操作，如访问某个链接，某个资源文件等。
	 * @param principalCollection
	 * @return
	 */
	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection arg0) {
		// TODO Auto-generated method stub
		return null;
	}




}

4.注册时用户的密码需要进行SHA-1盐加密

public User sha1Password(User user){
		//随机数 + 用户账号作为salt值
		String salt = new SecureRandomNumberGenerator().nextBytes().toHex() + user.getAccount();
		// 对密码加盐进行1024次SHA1加密
		String _password = new SimpleHash("SHA-1", user.getPassword(), salt, 1024).toHex();
		user.setSalt(salt);
		//通过盐值加密密码
		user.setPassword(_password);
		return user;
}
