2.4 配置視圖信息
application.properties
server.port=8080 server.servlet.context-path=/shiro spring.application.name=shiro spring.mvc.view.prefix=/ spring.mvc.view.suffix=.jsp
2.5 解決IDEA沖突問(wèn)題
JSP 與IDEA 與SpringBoot存在一定的不兼容，修改此配置即可解決
2.6 測(cè)試搭建的環(huán)境
3. 整合Shiro
3.1 引入依賴
pom.xml
<!--引入shrio-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring-boot-starter</artifactId>
<version>1.5.3</version>
</dependency>
3.2 自定義Realm
在shiro文件夾下創(chuàng)建realm文件夾
package com.test.shiro.realm;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
/**
* 自定義Realm
*/
public class CustomerRealm extends AuthorizingRealm {
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
return null;
}
}
3.3 Shiro配置
在config文件夾中創(chuàng)建ShiroConfig.java
@Configuration
public class ShiroConfig {
//ShiroFilter過(guò)濾所有請(qǐng)求
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//給ShiroFilter配置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
//配置系統(tǒng)受限資源
//配置系統(tǒng)公共資源
Map<String, String> map = new HashMap<String, String>();
map.put("/index.jsp","authc");//表示這個(gè)資源需要認(rèn)證和授權(quán)
// 設(shè)置認(rèn)證界面路徑
shiroFilterFactoryBean.setLoginUrl("/login.jsp");
shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
return shiroFilterFactoryBean;
}
//創(chuàng)建安全管理器
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(realm);
return securityManager;
}
//創(chuàng)建自定義Realm
@Bean
public Realm getRealm() {
CustomerRealm realm = new CustomerRealm();
return realm;
}
}
3.4 啟動(dòng)測(cè)試
輸入http://localhost:8080/shiro/index.jsp，發(fā)現(xiàn)需要跳轉(zhuǎn)到login.jsp
4. 常見(jiàn)過(guò)濾器
注意: shiro提供和多個(gè)默認(rèn)的過(guò)濾器，我們可以用這些過(guò)濾器來(lái)配置控制指定url的權(quán)限：
5. 認(rèn)證和退出
5.1 在index.jsp添加a標(biāo)簽
index.jsp
<a href="${pageContext.request.contextPath}/user/logout" rel="external nofollow" rel="external nofollow" >退出登錄</a>
5.2 編寫(xiě)controller
UserController.java
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping("logout")
public String logout() {
Subject subject = SecurityUtils.getSubject();
subject.logout();
return "redirect:/login.jsp";
}
@RequestMapping("/login")
public String login(String username, String password) {
//獲取主題對(duì)象
Subject subject = SecurityUtils.getSubject();
try {
subject.login(new UsernamePasswordToken(username,password));
System.out.println("登錄成功?。?！");
return "redirect:/index.jsp";
} catch (UnknownAccountException e) {
e.printStackTrace();
System.out.println("用戶錯(cuò)誤?。?！");
} catch (IncorrectCredentialsException e) {
System.out.println("密碼錯(cuò)誤?。?！");
}
return "redirect:/login.jsp";
}
}
5.3 修改自定義Realm
CustomerRealm.java
/**
* 自定義Realm
*/
public class CustomerRealm extends AuthorizingRealm {
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
return null;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
String principal = (String) authenticationToken.getPrincipal();
if ("zhangsan".equals(principal)) {
return new SimpleAuthenticationInfo(principal,"123456",this.getName());
}
return null;
}
}
5.4 修改ShiroConfig配置
ShiroConfig.java
公共資源一定是在受限資源上面，不然會(huì)造成死循環(huán)。
@Configuration
public class ShiroConfig {
//ShiroFilter過(guò)濾所有請(qǐng)求
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//給ShiroFilter配置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
//配置系統(tǒng)受限資源
//配置系統(tǒng)公共資源
Map<String, String> map = new HashMap<String, String>();
map.put("/user/login","anon");//表示這個(gè)為公共資源 一定是在受限資源上面
map.put("/**","authc");//表示這個(gè)受限資源需要認(rèn)證和授權(quán)
// 設(shè)置認(rèn)證界面路徑
shiroFilterFactoryBean.setLoginUrl("/login.jsp");
shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
return shiroFilterFactoryBean;
}
//創(chuàng)建安全管理器
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(Realm realm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(realm);
return securityManager;
}
//創(chuàng)建自定義Realm
@Bean
public Realm getRealm() {
CustomerRealm realm = new CustomerRealm();
return realm;
}
}
5.5 測(cè)試
登錄正常，登出正常，未登錄和登出后不能訪問(wèn)index.jsp
6. MDSalt的認(rèn)證實(shí)現(xiàn)
6.1 創(chuàng)建數(shù)據(jù)庫(kù)
SET NAMES utf8mb4; SET FOREIGN_KEY_CHECKS = 0; -- ---------------------------- -- Table structure for t_user -- ---------------------------- DROP TABLE IF EXISTS `t_user`; CREATE TABLE `t_user` ( `id` INT(6) NOT NULL AUTO_INCREMENT, `username` VARCHAR(40) DEFAULT NULL, `password` VARCHAR(40) DEFAULT NULL, `salt` VARCHAR(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; SET FOREIGN_KEY_CHECKS = 1;

6.4 創(chuàng)建實(shí)體類entity
User.java
@Data
@Accessors(chain = true)
@NoArgsConstructor
@AllArgsConstructor
public class User {
private String id;
private String username;
private String password;
private String salt;
}
6.5 創(chuàng)建DAO接口
UserDao.java
@Mapper
@Repository
public interface UserDao {
void save(User user);
User findByUsername(String username);
}
6.6 編寫(xiě)Mapper配置文件
UserDao.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.test.dao.UserDao">
<insert id="save" parameterType="User" useGeneratedKeys="true" keyProperty="id">
insert into t_user values(#{id},#{username},#{password},#{salt})
</insert>
<select id="findByUsername" parameterType="String" resultType="User">
select id,username,password,salt
from t_user
where username = #{username}
</select>
</mapper>
6.7 創(chuàng)建Service接口
UserService.java
public interface UserService {
//注冊(cè)用戶方法
void register(User user);
//根據(jù)用戶名查找用戶
User findByUsername(String username);
}
6.8 編寫(xiě)生成隨機(jī)鹽工具類
SaltUtil.java
public class SaltUtil {
public static String getSalt(int n) {
char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890!@#$%^&*()".toCharArray();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < n; i++) {
char c = chars[new Random().nextInt(chars.length)];
sb.append(c);
}
return sb.toString();
}
public static void main(String[] args) {
System.out.println(getSalt(4));
}
}
6.9 編寫(xiě)Service實(shí)現(xiàn)類
UserServiceImpl.java
@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public void register(User user) {
//1.獲取隨機(jī)鹽
String salt = SaltUtil.getSalt(8);
//2.將隨機(jī)鹽保存到數(shù)據(jù)
user.setSalt(salt);
//3.明文密碼進(jìn)行md5 + salt + hash散列
Md5Hash MD5 = new Md5Hash(user.getPassword(),salt,1024);
user.setPassword(MD5.toHex());
userDao.save(user);
}
@Override
public User findByUsername(String username) {
return userDao.findByUsername(username);
}
}
6.10 編寫(xiě)Controller
UserController.java
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/register")
public String register(User user) {
try {
userService.register(user);
return "redirect:/login.jsp";
} catch (Exception e) {
e.printStackTrace();
return "redirect:/register.jsp";
}
}
@RequestMapping("logout")
public String logout() {
Subject subject = SecurityUtils.getSubject();
subject.logout();
return "redirect:/login.jsp";
}
@RequestMapping("/login")
public String login(String username, String password) {
//獲取主題對(duì)象
Subject subject = SecurityUtils.getSubject();
try {
subject.login(new UsernamePasswordToken(username,password));
System.out.println("登錄成功！??！");
return "redirect:/index.jsp";
} catch (UnknownAccountException e) {
e.printStackTrace();
System.out.println("用戶錯(cuò)誤?。?！");
} catch (IncorrectCredentialsException e) {
System.out.println("密碼錯(cuò)誤！?。?);
}
return "redirect:/login.jsp";
}
}
6.11 修改自定義Realm

public class CustomerRealm extends AuthorizingRealm {
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
return null;
}
@Override

String principal = (String) authenticationToken.getPrincipal();
//獲取UserService對(duì)象
UserService userService = (UserService) ApplicationContextUtil.getBean("userService");
//System.out.println(userService);

if (!ObjectUtils.isEmpty(user)) {
return new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(), ByteSource.Util.bytes(user.getSalt()), this.getName());
}
return null;
}
}
6.12 編寫(xiě)獲取對(duì)象工具類
ApplicationContextUtil.java
@Component
public class ApplicationContextUtil implements ApplicationContextAware {
private static ApplicationContext context;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.context = applicationContext;
}
//根據(jù)bean名字獲取工廠中指定bean 對(duì)象
public static Object getBean(String beanName) {
return context.getBean(beanName);
}
}
6.13 修改Config
ShiroConfig.java
@Configuration
public class ShiroConfig {
//ShiroFilter過(guò)濾所有請(qǐng)求
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();

7.3.6 數(shù)據(jù)庫(kù)表數(shù)據(jù)設(shè)置
7.3.7 測(cè)試
8. shiro使用緩存
8.1 Cache
8.1.1 Cache 作用
Cache 緩存: 計(jì)算機(jī)內(nèi)存中一段數(shù)據(jù)
作用: 用來(lái)減輕DB的訪問(wèn)壓力,從而提高系統(tǒng)的查詢效率
流程:
8.1.2 使用shiro中默認(rèn)EhCache實(shí)現(xiàn)緩存
1.引入依賴
<!--引入shiro和ehcache--> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> <version>1.5.3</version> </dependency>
2.開(kāi)啟緩存
//3.創(chuàng)建自定義realm
@Bean
public Realm getRealm() {
CustomerRealm realm = new CustomerRealm();
HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
//設(shè)置使用MD5加密算法
credentialsMatcher.setHashAlgorithmName("md5");
//散列次數(shù)
credentialsMatcher.setHashIterations(1024);
realm.setCredentialsMatcher(credentialsMatcher);
//開(kāi)啟緩存管理器
realm.setCacheManager(new EhCacheManager());
realm.setCachingEnabled(true);//開(kāi)啟緩存
realm.setAuthenticationCachingEnabled(true);//開(kāi)啟認(rèn)證緩存
realm.setAuthenticationCacheName("authentication");
realm.setAuthorizationCachingEnabled(true);//開(kāi)啟授權(quán)緩存
realm.setAuthorizationCacheName("authorization");
return realm;
}
8.1.3 測(cè)試
注意:如果控制臺(tái)沒(méi)有任何sql展示說(shuō)明緩存已經(jīng)開(kāi)啟
8.2 Redis
8.2.1 shiro中使用Redis作為緩存實(shí)現(xiàn)
1.引入redis依賴
<!--redis整合springboot--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
2.配置redis連接
spring.redis.port=6379 spring.redis.host=localhost spring.redis.database=0
3.啟動(dòng)redis服務(wù)
4. 開(kāi)發(fā)RedisCacheManager
自定義shiro緩存管理器
RedisCacheManager.java
import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.apache.shiro.cache.CacheManager;
//自定義shiro緩存管理器
public class RedisCacheManager implements CacheManager {
//參數(shù)1:認(rèn)證或者是授權(quán)緩存的統(tǒng)一名稱
@Override
public <K, V> Cache<K, V> getCache(String cacheName) throws CacheException {
System.out.println(cacheName);
return new RedisCache<K,V>(cacheName);
}
}
5.開(kāi)RedisCache實(shí)現(xiàn)
//自定義redis緩存的實(shí)現(xiàn)
public class RedisCache<k,v> implements Cache<k,v> {
private String cacheName;
public RedisCache() {
}
public RedisCache(String cacheName) {
this.cacheName = cacheName;
}
@Override

return (v) getRedisTemplate().opsForHash().get(this.cacheName, k.toString());
}
@Override
public v put(k k, v v) throws CacheException {
System.out.println("put key: "+k);
System.out.println("put value:"+v);
getRedisTemplate().opsForHash().put(this.cacheName,k.toString(), v);
return null;
}
@Override
public v remove(k k) throws CacheException {
System.out.println("=============remove=============");
return (v) getRedisTemplate().opsForHash().delete(this.cacheName,k.toString());
}
@Override
public void clear() throws CacheException {
System.out.println("=============clear==============");
getRedisTemplate().delete(this.cacheName);
}
@Override
public int size() {
return getRedisTemplate().opsForHash().size(this.cacheName).intValue();
}
@Override
public Set<k> keys() {
return getRedisTemplate().opsForHash().keys(this.cacheName);
}
@Override
public Collection<v> values() {
return getRedisTemplate().opsForHash().values(this.cacheName);
}
private RedisTemplate getRedisTemplate(){
RedisTemplate redisTemplate = (RedisTemplate) ApplicationContextUtil.getBean("redisTemplate");
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
return redisTemplate;
}
}
6. 啟動(dòng)項(xiàng)目測(cè)試發(fā)現(xiàn)報(bào)錯(cuò) 錯(cuò)誤解釋: 由于shiro中提供的simpleByteSource實(shí)現(xiàn)沒(méi)有實(shí)現(xiàn)序列化,所有在認(rèn)證時(shí)出現(xiàn)錯(cuò)誤信息

9.6 啟動(dòng)測(cè)試
10. shiro標(biāo)簽在jsp使用
需要在jsp頁(yè)面中引入標(biāo)簽 <%@ taglib uri="http://shiro.apache.org/tags" prefix="shiro" %> 標(biāo)簽： <shiro:authenticated> 登錄之后 <shiro:notAuthenticated> 不在登錄狀態(tài)時(shí) <shiro:guest> 用戶在沒(méi)有RememberMe時(shí) <shiro:user> 用戶在RememberMe時(shí) <shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色時(shí) <shiro:hasRole name="abc"> 擁有角色abc <shiro:lacksRole name="abc"> 沒(méi)有角色abc <shiro:hasPermission name="abc"> 擁有權(quán)限資源abc <shiro:lacksPermission name="abc"> 沒(méi)有abc權(quán)限資源 <shiro:principal> 顯示用戶身份名稱 <shiro:principal property="username"/> 顯示用戶身份中的屬性值
11. Shiro整合springboot之thymeleaf權(quán)限控制
11.1 引入依賴
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>2.0.0</version>
</dependency>
11.2 頁(yè)面中引入命名空間
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">
11.3 常見(jiàn)權(quán)限控制標(biāo)簽使用

<p shiro:lacksRole="developer"><!-- 沒(méi)有該角色 -->
Sorry, you are not allowed to developer the system.
<!-- 驗(yàn)證當(dāng)前用戶是否屬于以下所有角色。 -->
<p shiro:hasAllRoles="developer, 2"><!-- 角色與判斷 -->

<a shiro:hasPermission="userInfo:add" href="createUser.html" rel="external nofollow" rel="external nofollow" >添加用戶</a><!-- 擁有權(quán)限 -->
<!-- 與hasPermission標(biāo)簽邏輯相反，當(dāng)前用戶沒(méi)有制定權(quán)限時(shí)，驗(yàn)證通過(guò)。 -->
<p shiro:lacksPermission="userInfo:del"><!-- 沒(méi)有權(quán)限 -->
Sorry, you are not allowed to delete user accounts.
<!-- 驗(yàn)證當(dāng)前用戶是否擁有以下所有角色。 -->

<a shiro:hasPermission="pp" href="createUser.html" rel="external nofollow" rel="external nofollow" >Create a new User</a>11.4 加入shiro的方言配置
頁(yè)面標(biāo)簽不起作用一定要記住加入方言處理
@Bean(name = "shiroDialect")
public ShiroDialect shiroDialect(){
return new ShiroDialect();
}
