import org.springframework.beans.factory.annotation.Autowired;
import java.util.Collection;
import java.util.HashSet;
import java.util.List;
/**

*/
public class MyShiroRealm extends AuthorizingRealm {
@Autowired
private SysUserService sysUserServiceImpl;
@Autowired
private SysPermissionService sysPermissionServiceImpl;
private String username;
// 系统授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
Subject subject = SecurityUtils.getSubject();//获取主体对象
String username =(String ) subject.getPrincipal();//获取用户身份信息
List<SysPermission> permissions = sysPermissionService.queryPermissionsByLoginName(username);//根据用户名获取用户的权限信息
// 权限去重
Collection<String > perms = new HashSet<>();
for (SysPermission perm: permissions ) {
perms.add(perm.getPermName());
}
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
simpleAuthorizationInfo.addStringPermissions(perms);//授权
return simpleAuthorizationInfo;
}
//用户认证
@Override

//根据用户信息查询数据库获取后端的用户身份，转交给securityManager判定
SysUser user1 = sysUserService.queryUserByLoginName(username);//从数据库直接取
System.out.println(user1);
if(user1!=null) {
SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(user1.getLoginName(), user1.getPassword(), getName());
return simpleAuthenticationInfo;
}
return null;
}
}
b、自定义Shiro配置管理
ShiroConfig.java
package com.qf.config;
import com.qf.shiro.MyShiroRealm;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.HashMap;
import java.util.Map;
/**
* Created by 54110 on 2019-07-05.
*/
@Configuration
public class ShiroConfig {
@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
Map<String ,String> map = new HashMap<>();
map.put("/main","authc"); //必须登录才可访问
map.put("/one","perms[user_edit]");//只有特定权限（“user_edit”）的用户登录后才可访问
map.put("/two","perms[user_forbidden]");//只有特定权限（“user_forbidden”）的用户登录后才可访问
shiroFilterFactoryBean.setLoginUrl("/login");//设置登录页（匿名）
shiroFilterFactoryBean.setUnauthorizedUrl("/unauth");//权限不足的错误提示页
shiroFilterFactoryBean.setFilterChainDefinitionMap(map);//装配拦截策略
return shiroFilterFactoryBean;
}
// 配置安全管理器（注入Realm对象）
@Bean(name="defaultWebSecurityManager")
public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("myShiroRealm") MyShiroRealm myShiroRealm){
DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
defaultWebSecurityManager.setRealm(myShiroRealm);
return defaultWebSecurityManager;
}
@Bean(name="myShiroRealm") //使用该注解是的Realm对象由spring容器管理
public MyShiroRealm myShiroRealm(){
MyShiroRealm shiroRealm = new MyShiroRealm();
return shiroRealm;
}
}
地址栏输入http://localhost:8080/login

当单击logout链接时，系统重回登录页。此时使用用户test2密码test2再次登录。因test2用户无case one权限，有case two权限，所以当test2用户单击case two时会显示如下页面：

}
在数据表中存的密码不应该是12345，而应该是12345加密之后的字符串，而且还要求这个加密算法是不可逆的，即由加密后的字符串不能反推回来原来的密码，如果能反推回来那这个加密是没有意义的。
著名的加密算法，比如 MD5，SHA1
1). 如何把一个字符串加密为MD5
2). 使用MD5加密算法后，前台用户输入的字符串如何使用MD5加密，需要做的是将当前的Realm 的credentialsMatcher属性，替换为Md5CredentialsMatcher 由于Md5CredentialsMatcher已经过期了，推荐使用HashedCredentialsMatcher 并设置加密算法即可。
1). 修改ShiroConfig.java文件添加如下内容；
/**
* 密码校验规则HashedCredentialsMatcher
* 这个类是为了对密码进行编码的 ,
* 防止密码在数据库里明码保存 , 当然在登陆认证的时候 ,
* 这个类也负责对form里输入的密码进行编码
* 处理认证匹配处理器：如果自定义需要实现继承HashedCredentialsMatcher
*/
@Bean("hashedCredentialsMatcher")
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
//指定加密方式为MD5
credentialsMatcher.setHashAlgorithmName("MD5");
//加密次数
credentialsMatcher.setHashIterations(1024);
credentialsMatcher.setStoredCredentialsHexEncoded(true);
return credentialsMatcher;
}
@Bean("myShiroRealm")
public MyShiroRealm myShiroRealm(@Qualifier("hashedCredentialsMatcher") HashedCredentialsMatcher matcher) {
MyShiroRealm authRealm = new MyShiroRealm();
authRealm.setAuthorizationCachingEnabled(false);
authRealm.setCredentialsMatcher(matcher);
return authRealm;
}
2).修改MyRealm.java的认证逻辑如下：
//用户认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal();//获取用户信息
SysUser user1 = sysUserService.queryUserByLoginName(username);//从数据库直接取
System.out.println(user1);
if(user1!=null) {
//当前realm对象的name
String realmName = getName();
//盐值
ByteSource credentialsSalt = ByteSource.Util.bytes(username);
//封装用户信息，构建AuthenticationInfo对象并返回
AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(username, user1.getPassword(), credentialsSalt, realmName);
return authcInfo;
}
return null;
}
3). 通过 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 我们可以得到"12345"经过MD5 加密1024后的字符串；
package com.jeffrey;
import org.apache.shiro.crypto.hash.SimpleHash;
import org.apache.shiro.util.ByteSource;
/**
* Created by jeffrey on 2019/4/8.
*/
public class MD5Salt {
public static void main(String[] args){
String hashAlgorithName = "MD5";//加密算法
String password = "12345";//登陆时的密码
int hashIterations =1024;//加密次数
ByteSource credentialsSalt = ByteSource.Util.bytes("admin2");//使用登录名做为salt
SimpleHash simpleHash = new SimpleHash(hashAlgorithName, password, credentialsSalt, hashIterations);
System.out.println("ok "+simpleHash);
}
}
使用密文替换数据库中的明文密码；
为什么使用 MD5 盐值加密:
希望即使两个原始密码相同，加密得到的两个字符串也不同。
如何做到:
1). 在 doGetAuthenticationInfo 方法返回值创建 SimpleAuthenticationInfo 对象的时候, 需要使用SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName) 构造器
2). 使用 ByteSource.Util.bytes() 来计算盐值.
3). 盐值需要唯一: 一般使用随机字符串或 user id
4). 使用 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 来计算盐值加密后的密码的值.
