Spring Security是一個可以爲基於Spring的企業應用系統提供聲明式的安全訪問控制解決方案的安全框架。它提供了一組能夠在Spring應用上下文中配置的Bean,充分利用了Spring IoC,DI(控制反轉Inversion of Control ,DI:Dependency Injection 依賴注入)和AOP(面向切面編程)功能,爲應用系統提供聲明式的安全訪問控制功能,減小了爲企業系統安全控制編寫大量重複代碼的工做。css
(1)建立工程spring-security-demo ,pom.xml內容html
<properties>java <spring.version>4.2.4.RELEASE</spring.version>web </properties>spring <dependencies>數據庫 <dependency>express <groupId>org.springframework</groupId>apache <artifactId>spring-core</artifactId>編程 <version>${spring.version}</version>api </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>4.1.0.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <!-- java編譯插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <!-- 指定端口 --> <port>9090</port> <!-- 請求路徑 --> <path>/</path> </configuration> </plugin> </plugins> </build> |
(2)建立web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-security.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app> |
(3)建立index.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>首頁</title> </head> <body> 歡迎進入神奇的spring security世界~~~ </body> </html> |
(4)建立spring 配置文件spring-security.xml
<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd"> <http pattern="/*.html" security="none"/> <http pattern="/css/**" security="none"/> <http pattern="/img/**" security="none"/> <http pattern="/js/**" security="none"/> <http pattern="/plugins/**" security="none"/> <http pattern="/seller/add.do" security="none"/> <!-- use-expressions:設置是否啓動SpEL表達式,默認值是true。 --> <http use-expressions="false"> <!-- 配置SpringSecurity的攔截路徑(攔截規則) * pattern:配置攔截規則。 /* 表明的是根路徑下的全部資源(不包含子路徑) /**表明的是根路徑下全部的資源(包含子路徑) * access:設置角色 角色命名 ROLE_角色名稱 如: ROLE_USER --> <intercept-url pattern="/**" access="ROLE_SELLER"/> <!-- 開啓表單驗證 username-parameter="username" password-parameter="password" login-page :登陸頁面名稱 以 / 開始 default-target-url :登陸成功後跳轉的頁面 login-processing-url:提交的路徑的設置 默認值"/login" 能夠修改 --> <form-login login-page="/login.html" default-target-url="/admin/index.html" always-use-default-target="true" authentication-failure-url="/login.html"/> <!-- 不使用csrf的校驗 --> <csrf disabled="true"/> <!-- 配置框架頁面不攔截 --> <headers> <frame-options policy="SAMEORIGIN"/> </headers> <!-- 註銷的配置 --> <logout logout-url="/logout" logout-success-url="/shoplogin.html" /> </http> <!-- 配置認證管理器 --> <authentication-manager> <!-- 認證的提供者 --> <authentication-provider user-service-ref="userDetailsService"> </authentication-provider> </authentication-manager> <!-- 配置自定義的認證類 --> <beans:bean id="userDetailsService" class="com.luli.code.service.UserDetailsServiceImpl"> <beans:property name="sellerService" ref="sellerService"></beans:property> </beans:bean> </beans:beans>
由於登陸頁會被反覆重定向。
login-page:指定登陸頁面。
authentication-failure-url:指定了身份驗證失敗時跳轉到的頁面。
default-target-url:指定了成功進行身份驗證和受權後默認呈現給用戶的頁面。
csrf disabled="true" 關閉csrf ,若是不加會出現錯誤
CSRF(Cross-site request forgery)跨站請求僞造,也被稱爲「One Click Attack」或者Session Riding,一般縮寫爲CSRF或者XSRF,是一種對網站的惡意利用。
IDEA啓動tomcat顯示build success但沒法繼續啓動的解決方法
<plugin>
告訴Tomcat插件,當前不是使用war包裝。在pom.xml的tomcat plugin的configuration中加入<ignorePackaging>true</ignorePackaging>,即告訴tomcat啓動時忽略當前是否有war包,再次運行tomcat7:run命令,tomcat便可正常啓動。 |
access="ROLE_USER" access 必須是ROLE_開頭
此案例咱們沒有登陸頁,而是使用了系統自動生成的登錄頁,效果以下:
配置說明:
intercept-url 表示攔截頁面
/* 表示的是該目錄下的資源,只包括本級目錄不包括下級目錄
/** 表示的是該目錄以及該目錄下全部級別子目錄的資源
form-login 爲開啓表單登錄
use-expressions 爲是否使用使用 Spring 表達式語言( SpEL ),默認爲true ,若是開啓,則攔截的配置應該寫成如下形式
login-processing-url=」/login2」 指定其餘登陸頁
username-parameter="" password-parameter="" 來改寫login的 用戶名和屬性名
<intercept-url pattern="/**" access="hasRole('ROLE_USER')" /> |
(5)構建登錄頁login.html:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>登錄</title> </head> <body>
--歡迎的登錄個人系統-- <form action="/login" method="post"> 用戶名:<input name="username"><br> 密碼:<input name="password"><br> <button>登錄</button> </form> </body> </html> |
(6)構建登錄失敗頁 login_error.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>首頁</title> </head> <body> 用戶名或密碼錯誤~~~ </body> </html> |
(7) UserDetailsServiceImpl.java文件
package com.luli.code.service; import com.luli.code.pojo.Seller; import org.springframework.security.core.GrantedAuthority; import org.springframework.security.core.authority.SimpleGrantedAuthority; import org.springframework.security.core.userdetails.User; import org.springframework.security.core.userdetails.UserDetails; import org.springframework.security.core.userdetails.UserDetailsService; import org.springframework.security.core.userdetails.UsernameNotFoundException; import java.util.ArrayList; import java.util.List; public class UserDetailsServiceImpl implements UserDetailsService { private SellerService sellerService; public void setSellerService(SellerService sellerService) { this.sellerService = sellerService; } /*自定義登陸驗證*/ @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { List<GrantedAuthority> grantedAuthorities = new ArrayList<>(); grantedAuthorities.add(new SimpleGrantedAuthority("ROLE_SELLER")); //查找數據庫 Seller seller = sellerService.findOne(username); if(seller != null && ("1").equals(seller.getStatus())) { return new User(username, seller.getPassword(), grantedAuthorities); //判斷帳戶密碼
}else{ return null; } } }
