優(yōu)質(zhì)文章，第一時(shí)間送達(dá)

寫這篇文章主要是記錄我的學(xué)習(xí)過程，剛開始在網(wǎng)上找資料的時(shí)候，網(wǎng)上的資料很亂。所以自己整合了一個(gè)比較簡(jiǎn)單的shiro的使用方法，shiro是什么、怎么用就不用我在這里詳細(xì)的講解了。

1.添加依賴

  <dependency>            <groupId>org.apache.shirogroupId>            <artifactId>shiro-springartifactId>            <version>1.4.0version>        dependency>        <dependency>            <groupId>org.apache.shirogroupId>            <artifactId>shiro-coreartifactId>            <version>1.4.0version>        dependency>

2.配置文件

shiroconfig

package com.xl.shiro;
import org.apache.shiro.mgt.SecurityManager;import org.apache.shiro.session.mgt.SessionManager;import org.apache.shiro.spring.LifecycleBeanPostProcessor;import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;import org.apache.shiro.web.mgt.DefaultWebSecurityManager;import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;
import java.util.LinkedHashMap;import java.util.Map;
/** * Shiro 配置文件 */@Configurationpublic class ShiroConfig {    /**     * Session Manager：會(huì)話管理     * 即用戶登錄后就是一次會(huì)話，在沒有退出之前，它的所有信息都在會(huì)話中；     * 會(huì)話可以是普通JavaSE環(huán)境的，也可以是如Web環(huán)境的；     */    @Bean("sessionManager")    public SessionManager sessionManager(){        DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();        //設(shè)置session過期時(shí)間        sessionManager.setGlobalSessionTimeout(60 * 60 * 1000);        sessionManager.setSessionValidationSchedulerEnabled(true);        // 去掉shiro登錄時(shí)url里的JSESSIONID        sessionManager.setSessionIdUrlRewritingEnabled(false);        return sessionManager;    }
    /**     * SecurityManager：安全管理器     */    @Bean("securityManager")    public SecurityManager securityManager(UserRealm userRealm, SessionManager sessionManager) {        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();        //securityManager.setSessionManager(sessionManager);        securityManager.setRealm(userRealm);        return securityManager;    }    /**     * ShiroFilter是整個(gè)Shiro的入口點(diǎn)，用于攔截需要安全控制的請(qǐng)求進(jìn)行處理     */    @Bean("shiroFilter")    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) {        ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean();        shiroFilter.setSecurityManager(securityManager);        shiroFilter.setLoginUrl("/userLogin");        shiroFilter.setUnauthorizedUrl("/");        Map<String, String> filterMap = new LinkedHashMap<>();         //authc:所有url都必須認(rèn)證通過才可以訪問; anon:所有url都都可以匿名訪問,先配置anon再配置authc,當(dāng)你變?yōu)閍uthc的時(shí)候，登入將會(huì)跳轉(zhuǎn)/userLogin        filterMap.put("/userLogin", "anon");        shiroFilter.setFilterChainDefinitionMap(filterMap);        return shiroFilter;    }    /**     * 管理Shiro中一些bean的生命周期     */    @Bean("lifecycleBeanPostProcessor")    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {        return new LifecycleBeanPostProcessor();    }    /**     * 掃描上下文，尋找所有的Advistor(通知器）     * 將這些Advisor應(yīng)用到所有符合切入點(diǎn)的Bean中。     */    @Bean    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {        DefaultAdvisorAutoProxyCreator proxyCreator = new DefaultAdvisorAutoProxyCreator();        proxyCreator.setProxyTargetClass(true);        return proxyCreator;    }    /**     * 匹配所有加了 Shiro 認(rèn)證注解的方法     */    @Bean    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {        AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();        advisor.setSecurityManager(securityManager);        return advisor;    }}

這個(gè)配置文件是我們進(jìn)行權(quán)限和登入認(rèn)證的時(shí)候需要用到的

package com.xl.shiro;
import org.apache.shiro.authc.*;import org.apache.shiro.authc.credential.CredentialsMatcher;import org.apache.shiro.authc.credential.HashedCredentialsMatcher;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.authz.SimpleAuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection;import org.apache.shiro.util.ByteSource;import org.springframework.stereotype.Component;import org.springframework.util.StringUtils;
import javax.annotation.Resource;import java.util.*;
/** * Shiro 認(rèn)證實(shí)體 */@Componentpublic class UserRealm extends AuthorizingRealm {
    @Resource    private SysUserMapper sysUserMapper ;    @Resource    private SysMenuMapper sysMenuMapper ;
    /**     * 授權(quán)(驗(yàn)證權(quán)限時(shí)調(diào)用)     * 獲取用戶權(quán)限集合     */    @Override    public AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {        Object user = principals.getPrimaryPrincipal();        if(user == null) {            throw new UnknownAccountException("賬號(hào)不存在");        }        List<String> permsList;        //默認(rèn)用戶擁有最高權(quán)限        User user1 =new User();        user1.setUserid(1);        user1.setUserid1(2);        user1.setUserid2(3);        user1.setUserid3("123");        List menuList = sysMenuMapper.selectList(user1);        permsList = new ArrayList<>(menuList.size());        for(Map menu : menuList){            permsList.add(menu.get("perms").toString());        }        //用戶權(quán)限列表        Set<String> permsSet = new HashSet<>();        for(String perms : permsList){            if(StringUtils.isEmpty(perms)){                continue;            }            permsSet.addAll(Arrays.asList(perms.trim().split(",")));        }        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();        info.setStringPermissions(permsSet);        return info;    }
    /**     * 認(rèn)證(登錄時(shí)調(diào)用)     * 驗(yàn)證用戶登錄     */    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authToken) throws AuthenticationException {        UsernamePasswordToken token = (UsernamePasswordToken)authToken;        //查詢用戶信息        Map  user = sysUserMapper.selectOne(token.getUsername());        //賬號(hào)不存在        if(user == null) {            throw new UnknownAccountException("賬號(hào)或密碼不正確");        }        //賬號(hào)鎖定       /* if(user.getStatus() == 0){            throw new LockedAccountException("賬號(hào)已被鎖定,請(qǐng)聯(lián)系管理員");        }*/        SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.get("password"),getName());//        SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user,user.get("password"),getName());        return info;    }
  /*   重寫這個(gè)方法是因?yàn)榈侨腧?yàn)證的時(shí)候，從數(shù)據(jù)庫(kù)取出的密碼是加密過的，shiro進(jìn)行密碼驗(yàn)證的時(shí)候會(huì)將明文密碼加密后與數(shù)據(jù)庫(kù)的密碼進(jìn)行對(duì)比。        */    @Override    public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {        HashedCredentialsMatcher shaCredentialsMatcher = new HashedCredentialsMatcher();        shaCredentialsMatcher.setHashAlgorithmName(ShiroUtils.hashAlgorithmName);       // shaCredentialsMatcher.setHashIterations(ShiroUtils.hashIterations);//這里就是自己設(shè)置如何去加密的多少次        super.setCredentialsMatcher(shaCredentialsMatcher);    }}

3.添加shiro工具類

package com.xl.shiro;import org.apache.shiro.SecurityUtils;import org.apache.shiro.crypto.hash.SimpleHash;import org.apache.shiro.session.Session;import org.apache.shiro.subject.Subject;
/** * Shiro工具類 */public class ShiroUtils {    /**  加密算法 */    public final static String hashAlgorithmName = "SHA-256";    /**  循環(huán)次數(shù) */    public final static int hashIterations = 16;
    public static String sha256(String password, String salt) {        return new SimpleHash(hashAlgorithmName, password, salt, hashIterations).toString();    }
    // 獲取一個(gè)測(cè)試賬號(hào) admin    public static void main(String[] args) {        // 3743a4c09a17e6f2829febd09ca54e627810001cf255ddcae9dabd288a949c4a      //  System.out.println(sha256("qqq","123")) ;        System.out.println(new SimpleHash(hashAlgorithmName, "admin").toString()) ;    }
    /**     * 獲取會(huì)話     */    public static Session getSession() {        return SecurityUtils.getSubject().getSession();    }
    /**     * Subject：主體，代表了當(dāng)前“用戶”     */    public static Subject getSubject() {        return SecurityUtils.getSubject();    }
  /*  public static SysUserEntity getUserEntity() {        return (SysUserEntity)SecurityUtils.getSubject().getPrincipal();    }
    public static Long getUserId() {        return getUserEntity().getUserId();    }*/
    public static void setSessionAttribute(Object key, Object value) {        getSession().setAttribute(key, value);    }
    public static Object getSessionAttribute(Object key) {        return getSession().getAttribute(key);    }
    public static boolean isLogin() {        return SecurityUtils.getSubject().getPrincipal() != null;    }
    public static void logout() {        SecurityUtils.getSubject().logout();    }}

4.重寫拋出異常類

package com.xl.shiro;
import org.apache.shiro.authz.AuthorizationException;import org.springframework.web.bind.annotation.ExceptionHandler;import org.springframework.web.bind.annotation.RestControllerAdvice;
@RestControllerAdvicepublic class ShiroException {
    @ExceptionHandler(AuthorizationException.class)    public String authorizationException (){        return "抱歉您沒有權(quán)限訪問該內(nèi)容!";    }
    @ExceptionHandler(Exception.class)    public String handleException(Exception e){        return "系統(tǒng)異常!";    }
}

5.控制層

package com.xl.shiro;
import lombok.extern.slf4j.Slf4j;import org.apache.shiro.authc.UsernamePasswordToken;import org.apache.shiro.authz.annotation.RequiresPermissions;import org.apache.shiro.subject.Subject;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Value;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;import java.util.List;
/** * Shrio 測(cè)試方法控制層 */@RestController@Slf4jpublic class ShiroController {@Value("${my}")private Integer time;    private static Logger LOGGER = LoggerFactory.getLogger(ShiroController.class) ;
    @Resource    private SysMenuMapper sysMenuMapper ;    /**     * 登錄測(cè)試     * http://localhost:7011/userLogin?userName=admin&passWord=admin     */    @RequestMapping("/userLogin")    public void userLogin (            @RequestParam(value = "userName") String userName,            @RequestParam(value = "passWord") String passWord){        try{            Subject subject = ShiroUtils.getSubject();//            String ps=ShiroUtils.sha256(passWord,"123");            log.info(time.toString());            UsernamePasswordToken token = new UsernamePasswordToken(userName, passWord);            subject.login(token);            LOGGER.info("登錄成功");        }catch (Exception e) {            e.printStackTrace();        }    }
    /**     * 服務(wù)器每次重啟請(qǐng)求該接口之前必須先請(qǐng)求上面登錄接口     * http://localhost:7011/menu/list 獲取所有菜單列表     * 權(quán)限要求：sys:user:shiro     */    @RequestMapping("/menu/list")    @RequiresPermissions("sys:user:shiro")    public List list(){        User user =new User();        user.setUserid(1);        user.setUserid1(2);        user.setUserid2(3);        user.setUserid3("123");        return sysMenuMapper.selectList(user) ;    }
    /**     * 用戶沒有該權(quán)限，無(wú)法訪問     * 權(quán)限要求：ccc:ddd:bbb     */    @RequestMapping("/menu/list2")    @RequiresPermissions("ccc:ddd:bbb")    public List list2(){        User user =new User();        user.setUserid(1);        user.setUserid1(2);        user.setUserid2(3);        user.setUserid3("123");        return sysMenuMapper.selectList(user) ;    }
    /**     * 退出測(cè)試     */    @RequestMapping("/userLogOut")    public String logout (){        ShiroUtils.logout();        return "success" ;    }}
