Shiro是一個功能強大且易於使用的Java安全框架,官網:https://shiro.apache.org/。java
主要功能有身份驗證、受權、加密和會話管理。
其它特性有Web支持、緩存、測試支持、容許一個用戶用另外一個用戶的身份進行訪問、記住我。web
Shiro有三個核心組件:Subject,SecurityManager和 Realm。spring
Subject:即當前操做「用戶」,「用戶」並不單單指人,也能夠是第三方進程、後臺賬戶或其餘相似事物。
SecurityManager:安全管理器,Shiro框架的核心,經過SecurityManager來管理全部Subject,並經過它來提供安全管理的各類服務。
Realm:域,充當了Shiro與應用安全數據間的「橋樑」或者「鏈接器」。也就是說,當對用戶執行認證(登陸)和受權(訪問控制)驗證時,Shiro會從應用配置的Realm中查找用戶及其權限信息。當配置Shiro時,必須至少指定一個Realm,用於認證和(或)受權。數據庫
Spring Boot 中整合Shiro,根據引入的依賴包shiro-spring和shiro-spring-boot-web-starter(當前版本都是1.4.2)不一樣有兩種不一樣方法。apache
方法一:引入依賴包shiro-spring緩存
一、IDEA中建立一個新的SpringBoot項目,pom.xml引用的依賴包以下:安全
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.2</version> </dependency>
二、建立Realm和配置shiroapp
(1)建立Realm框架
package com.example.demo.config; import org.apache.shiro.authc.*; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; public class MyRealm extends AuthorizingRealm { /**權限信息,暫不實現*/ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { return null; } /**身份認證:驗證用戶輸入的帳號和密碼是否正確。*/ @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { //獲取用戶輸入的帳號 String userName = (String) token.getPrincipal(); //驗證用戶admin和密碼123456是否正確 if (!"admin".equals(userName)) { throw new UnknownAccountException("帳戶不存在!"); } SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(userName, "123456", getName()); return authenticationInfo; //實際項目中,上面帳號從數據庫中獲取用戶對象,再判斷是否存在 /*User user = userService.findByUserName(userName); if (user == null) { throw new UnknownAccountException("帳戶不存在!"); } SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user,user.getPassword(), getName()); return authenticationInfo; */ } }
(2)配置Shirojsp
package com.example.demo.config; import org.apache.shiro.spring.web.ShiroFilterFactoryBean; import org.apache.shiro.web.mgt.DefaultWebSecurityManager; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.util.LinkedHashMap; import java.util.Map; @Configuration public class ShiroConfig { @Bean MyRealm myRealm() { return new MyRealm(); } @Bean DefaultWebSecurityManager securityManager() { DefaultWebSecurityManager manager = new DefaultWebSecurityManager(); manager.setRealm(myRealm()); return manager; } @Bean ShiroFilterFactoryBean shiroFilterFactoryBean() { ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean(); bean.setSecurityManager(securityManager()); //若是不設置默認會自動尋找Web工程根目錄下的"/login.jsp"頁面 bean.setLoginUrl("/login"); //登陸成功後要跳轉的連接 bean.setSuccessUrl("/index"); //未受權界面 bean.setUnauthorizedUrl("/403"); //配置不會被攔截的連接 Map<String, String> map = new LinkedHashMap<>(); map.put("/doLogin", "anon"); map.put("/**", "authc"); bean.setFilterChainDefinitionMap(map); return bean; } }
三、控制器測試方法
package com.example.demo.controller; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.UnknownAccountException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.subject.Subject; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class LoginController { @GetMapping("/login") public String login() { return "登陸頁面..."; } @PostMapping("/doLogin") public String doLogin(String userName, String password) { Subject subject = SecurityUtils.getSubject(); try { subject.login(new UsernamePasswordToken(userName, password)); return "登陸成功!"; } catch (UnknownAccountException e) { return e.getMessage(); } catch (AuthenticationException e) { return "登錄失敗,密碼錯誤!"; } } //若是沒有先登錄,訪問會跳到/login @GetMapping("/index") public String index() { return "index"; } @GetMapping("/403") public String unauthorizedRole(){ return "沒有權限"; } }
方法二:引入依賴包shiro-spring-boot-web-starter
一、pom.xml中刪除shiro-spring,引入shiro-spring-boot-web-starter
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring-boot-web-starter</artifactId> <version>1.4.2</version> </dependency>
二、建立Realm和配置shiro
(1)建立Realm,代碼和方法一的同樣。
(2)配置Shiro
package com.example.demo.config; import org.apache.shiro.spring.web.config.DefaultShiroFilterChainDefinition; import org.apache.shiro.spring.web.config.ShiroFilterChainDefinition; import org.apache.shiro.web.mgt.DefaultWebSecurityManager; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class ShiroConfig { @Bean MyRealm myRealm() { return new MyRealm(); } @Bean DefaultWebSecurityManager securityManager() { DefaultWebSecurityManager manager = new DefaultWebSecurityManager(); manager.setRealm(myRealm()); return manager; } @Bean ShiroFilterChainDefinition shiroFilterChainDefinition() { DefaultShiroFilterChainDefinition definition = new DefaultShiroFilterChainDefinition(); definition.addPathDefinition("/doLogin", "anon"); definition.addPathDefinition("/**", "authc"); return definition; } }
(3)application.yml配置
shiro: unauthorizedUrl: /403 successUrl: /index loginUrl: /login
