HashedCredentialsMatcher

自定义Realm中使用散列

盐的使用

HashedCredentialsMatcher

1.修改CustomRealm类
代码入下：

package com.imooc.shiro.realm;

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.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.crypto.hash.Md5Hash;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

import java.util.HashMap;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

/**

public class CustomRealm extends AuthorizingRealm

Map<String,String> userMap = new HashMap<>(16);

userMap.put("Mark","e10adc3949ba59abbe56e057f20f883e");

super.setName("customRealm");

//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection)

String userName = (String) principalCollection.getPrimaryPrincipal();
//从数据库或者缓存中获取角色数据
Set<String> roles = getRolesByUserName(userName);
//从数据库或者缓存中获取权限数据
Set<String> permissions = getPermissionsByUserName(userName);
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
simpleAuthorizationInfo.setStringPermissions(permissions);
simpleAuthorizationInfo.setRoles(roles);

return simpleAuthorizationInfo;

private Set<String> getPermissionsByUserName(String userName)
Set<String> sets = new HashSet<>();
sets.add("user:delete");
sets.add("user:add");
return sets;

/**
*
* @param userName
* @return
*/
private Set<String> getRolesByUserName(String userName)
Set<String> sets = new HashSet<>();
sets.add("admin");
sets.add("user");
return sets;

//认证
//AuthenticationToken认证信息
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException

//1.从主体传过来的认证信息中，获得用户名
String userName = (String) authenticationToken.getPrincipal();

//2.通过用户名到数据库中获取凭证
String password = getPasswordByUserName(userName);
if(password == null)
return null;

SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo("Mark",password,"customRealm");
return authenticationInfo;

/**
* 模拟数据库查询凭证
* @param userName
* @return
*/
private String getPasswordByUserName(String userName)
return userMap.get(userName);

public static void main(String [] args)
Md5Hash md5Hash = new Md5Hash("123456");
System.out.println(md5Hash.toString());
