首先我需要在xml文件中声明.我要进行自定义用户的认证类,也就是我要自己从数据库中进行查询
<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:设置是否启动SpEL表达式,默认值是true。 --> <http use-expressions="false"> <!-- 配置SpringSecurity的拦截路径(拦截规则) * pattern:配置拦截规则。 /* 代表的是根路径下的所有资源(不包含子路径) /**代表的是根路径下所有的资源(包含子路径) * access:设置角色 角色命名 ROLE_角色名称 如: ROLE_USER --> <intercept-url pattern="/**" access="ROLE_SELLER"/> <!-- 开启表单验证 username-parameter="username" password-parameter="password" login-page :登录页面名称 以 / 开始 default-target-url :登录成功后跳转的页面 login-processing-url:提交的路径的设置 默认值"/login" 可以修改 --> <form-login login-page="/shoplogin.html" default-target-url="/admin/index.html" always-use-default-target="true" authentication-failure-url="/shoplogin.html"/> <!-- 不使用csrf的校验 --> <csrf disabled="true"/> <!-- 配置框架页面不拦截 --> <headers> <frame-options policy="SAMEORIGIN"/> </headers> <!-- 注销的配置 --> <logout logout-url="/logout" logout-success-url="/shoplogin.html" /> </http> <!-- 配置认证管理器 --> <authentication-manager> <!-- 认证的提供者 --> <authentication-provider user-service-ref="userDetailService"> <password-encoder ref="passwordEncoder"></password-encoder> </authentication-provider> </authentication-manager> <!-- 配置自定义的认证类 --> <beans:bean id="userDetailService" class="com.qingmu2.core.service.UserDetailServiceImpl"> <beans:property name="sellerService" ref="sellerService"></beans:property> </beans:bean> <!--加密时候使用的算法是BCryptPasswordEncoder--> <beans:bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
配置完自定义的文件以后,在需要自定义认证类的模块中实现
UserDetailsService
package com.qingmu2.core.service; import com.alibaba.dubbo.config.annotation.Reference; import com.qingmu2.core.pojo.seller.Seller; import org.springframework.beans.factory.annotation.Autowired; 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.HashMap; import java.util.HashSet; import java.util.List; /** * 自定义的认证类 * @Auther:qingmu * @Description:脚踏实地,只为出人头地 * @Date:Created in 8:33 2019/5/31 */ public class UserDetailServiceImpl implements UserDetailsService { private SellerService sellerService; public UserDetailServiceImpl() { } @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { Seller seller = sellerService.findOne(username); if(null!=seller){ //判断一次商家是否被审核通过. if("1".equals(seller.getStatus())){ //创建一个集合,用来存储权限 HashSet<GrantedAuthority> authorities = new HashSet<>(); authorities.add(new SimpleGrantedAuthority("ROLE_SELLER")); //将这个用户的信息返回给认证类 return new User(username,seller.getPassword(),authorities); } } //没有这个用户,则返回null return null; } public UserDetailServiceImpl(SellerService sellerService) { this.sellerService = sellerService; } public SellerService getSellerService() { return sellerService; } public void setSellerService(SellerService sellerService) { this.sellerService = sellerService; } }
