Shiro认证
Pom依赖
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.3.2</version> </dependency>
2、web.xml配置
<!-- shiro过滤器定义 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由ServletContainer管理 -->
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>通过逆向工程将五张表生成对应的model、mapper
Mapper中新增
<select id="queryByName" resultType="com.javaxl.ssm.model.ShiroUser" parameterType="java.lang.String">
select
<include refid="Base_Column_List" />
from t_shiro_user
where userName = #{userName}
</select>
Service层
package com.javaxl.ssm.service;
import com.javaxl.ssm.model.ShiroUser;
import java.util.Set;
/**
* @author 小李飞刀
* @site www.javaxl.com
* @company
* @create 2019-10-12 15:55
*/
public interface ShiroUserService {
public Set<String> getRolesByUserId(Integer userId);
public Set<String> getPersByUserId(Integer userId);
public ShiroUser queryByName(String userName);
}
package com.javaxl.ssm.service.impl;
import com.javaxl.ssm.mapper.ShiroUserMapper;
import com.javaxl.ssm.model.ShiroUser;
import com.javaxl.ssm.service.ShiroUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.Set;
/**
* @author 小李飞刀
* @site www.javaxl.com
* @company
* @create 2019-10-12 15:54
*/
@Service("shiroUserService")
public class ShiroUserServiceImpl implements ShiroUserService {
@Autowired
private ShiroUserMapper shiroUserMapper;
@Override
public Set<String> getRolesByUserId(Integer userId) {
return shiroUserMapper.getRolesByUserId(userId);
}
@Override
public Set<String> getPersByUserId(Integer userId) {
return shiroUserMapper.getPersByUserId(userId);
}
@Override
public ShiroUser queryByName(String userName) {
return shiroUserMapper.queryByName(userName);
}
}
3、自定义Realm
package com.javaxl.ssm.shiro;
import com.javaxl.ssm.model.ShiroUser;
import com.javaxl.ssm.model.User;
import com.javaxl.ssm.service.ShiroUserService;
import com.javaxl.ssm.service.UserService;
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.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import org.springframework.stereotype.Service;
/**
* @author 小李飞刀
* @site www.javaxl.com
* @company
* @create 2019-10-12 16:20
*/
public class MyRealm extends AuthorizingRealm {
private ShiroUserService shiroUserService;
public ShiroUserService getShiroUserService() {
return shiroUserService;
}
public void setShiroUserService(ShiroUserService shiroUserService) {
this.shiroUserService = shiroUserService;
}
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("身份认证...");
String username = token.getPrincipal().toString();
String password = token.getCredentials().toString();
ShiroUser user = shiroUserService.queryByName(username);
// 拿到数据库中的用户信息，放入token凭证中，用于controler进行对比
AuthenticationInfo info = new SimpleAuthenticationInfo(
user.getUsername(),
user.getPassword(),
ByteSource.Util.bytes(user.getSalt()),
this.getName()
);
return info;
}
}

导入上一篇博客所用的jsp
5、运行结果
在不登陆的情况下只能访问login.jsp
zs用户登录只能看到个人密码修改界面
ls用户登录，比zs多看到老师简介界面
6、数据库脚本

盐加密
盐加密工具类，在做新增用户的时候使用，将加密后的密码、及加密时候的盐放入数据库；
本篇博客中的表数据是现成的，暂时用不上这个工具类去生成数据；
7、盐加密工具类
package com.javaxl.ssm.util;
import org.apache.shiro.crypto.RandomNumberGenerator;
import org.apache.shiro.crypto.SecureRandomNumberGenerator;
import org.apache.shiro.crypto.hash.SimpleHash;
/**
* 用于shiro权限认证的密码工具类
*/
public class PasswordHelper {
/**
* 随机数生成器
*/
private static RandomNumberGenerator randomNumberGenerator = new SecureRandomNumberGenerator();
/**
* 指定hash算法为MD5
*/
private static final String hashAlgorithmName = "md5";
/**
* 指定散列次数为1024次，即加密1024次
*/
private static final int hashIterations = 1024;
/**
* true指定Hash散列值使用Hex加密存. false表明hash散列值用用Base64-encoded存储
*/
private static final boolean storedCredentialsHexEncoded = true;
/**
* 获得加密用的盐
*
* @return
*/
public static String createSalt() {
return randomNumberGenerator.nextBytes().toHex();
}
/**
* 获得加密后的凭证
*
* @param credentials 凭证(即密码)
* @param salt 盐
* @return
*/
public static String createCredentials(String credentials, String salt) {
SimpleHash simpleHash = new SimpleHash(hashAlgorithmName, credentials,
salt, hashIterations);
return storedCredentialsHexEncoded ? simpleHash.toHex() : simpleHash.toBase64();
}
/**
* 进行密码验证
*
* @param credentials 未加密的密码
* @param salt 盐
* @param encryptCredentials 加密后的密码
* @return
*/
public static boolean checkCredentials(String credentials, String salt, String encryptCredentials) {
return encryptCredentials.equals(createCredentials(credentials, salt));
}
public static void main(String[] args) {
//盐
String salt = createSalt();
System.out.println(salt);
System.out.println(salt.length());
//凭证+盐加密后得到的密码
String credentials = createCredentials("123", salt);
System.out.println(credentials);
System.out.println(credentials.length());
boolean b = checkCredentials("123", salt, credentials);
System.out.println(b);
}
