三、数据库加载健全比较
1、config配置
a.SecurityConfig.java
package org.pro.config; import jakarta.servlet.http.Cookie; import jakarta.servlet.http.HttpServletRequest; import jakarta.servlet.http.HttpServletResponse; import lombok.extern.slf4j.Slf4j; import org.pro.filter.JwtAuthenticationTokenFilter; import org.pro.filter.LoginFilter; import org.pro.service.ResourceService; import org.pro.service.UserService; import org.pro.utils.EncryptionUtils; import org.pro.utils.JwtUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;

return http.build(); } @Bean public AuthorizationFilter authorizationFilter() { return new AuthorizationFilter(new MyAuthorizationManager()); } @Bean public UserDetailsService userDetailsService() { return loginName -> { org.pro.model.User user = this.userService.getUserByName(loginName); if (user == null) { throw new UsernameNotFoundException("用户未找到"); } List<String> codes = user.getCodes(); String[] authCodeArr = new String[codes.size()]; return User.withUsername(loginName).password(user.getPassword()).authorities(codes.toArray(authCodeArr)).build(); }; } @Bean public RememberMeServices rememberMeServices(UserDetailsService userDetailsService) { TokenBasedRememberMeServices.RememberMeTokenAlgorithm encodingAlgorithm = TokenBasedRememberMeServices.RememberMeTokenAlgorithm.SHA256;

return rememberMe; } /** * 启动注入会调用 * @return * @throws Exception */ @Bean public LoginFilter loginFilter() throws Exception { LoginFilter loginFilter = new LoginFilter(); loginFilter.setAuthenticationManager(authenticationConfiguration.getAuthenticationManager());

} @Autowired public void setAuthenticationConfiguration(AuthenticationConfiguration authenticationConfiguration) { this.authenticationConfiguration = authenticationConfiguration; } }
b.新增MyAuthorizationManager.java
package org.pro.config; import jakarta.servlet.http.HttpServletRequest; import lombok.SneakyThrows; import org.pro.service.ConstantService; import org.pro.service.ResourceService; import org.pro.utils.SpringBeanUtils; import org.springframework.security.authorization.AuthorizationDecision; import org.springframework.security.authorization.AuthorizationManager; import org.springframework.security.core.Authentication; import org.springframework.security.core.GrantedAuthority; import org.springframework.util.CollectionUtils; import java.nio.file.AccessDeniedException; import java.util.Collection; import java.util.List; import java.util.function.Supplier; import java.util.stream.Collectors; /** * @author Administrator */ public class MyAuthorizationManager implements AuthorizationManager<HttpServletRequest> { @SneakyThrows @Override public AuthorizationDecision check(Supplier<Authentication> authentication, HttpServletRequest request) { // 获得请求资源定位 String requestURI = request.getRequestURI(); // 获取匿名code ConstantService constantService = SpringBeanUtils.getBean(ConstantService.class); String code = constantService.getCodeByCategory("no_login"); Collection<? extends GrantedAuthority> authorities = authentication.get().getAuthorities(); // UserDetailsService创建的user的codes List<String> list = authorities.stream().map(GrantedAuthority::getAuthority).collect(Collectors.toList()); ResourceService resourceService = SpringBeanUtils.getBean(ResourceService.class); // 匹配resource资源中的authorityCode List<String> codes = resourceService.getCodesByURI(requestURI); // 判断是否是匿名路径 if (codes.contains(code)) { return new AuthorizationDecision(true); } if (CollectionUtils.isEmpty(codes) || codes.size()<1 || !contains(codes, list)) { throw new AccessDeniedException("权限不足"); } return new AuthorizationDecision(false); } private boolean contains(List<String> codes, List<String> list) { for (String str : list) { for (String code : codes) { if(str.equals(code)) { return true; } } } return false; } }
2、工具类
a.新增SpringBeanUtils.java
package org.pro.utils; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; /** * @author Administrator */ @Component public class SpringBeanUtils implements ApplicationContextAware { private static ApplicationContext applicationContext; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { if(SpringBeanUtils.applicationContext == null) { SpringBeanUtils.applicationContext = applicationContext; } } /** * 获取applicationContext * * @return */ public static ApplicationContext getApplicationContext() { return applicationContext; } /** * 通过name获取bean * * @param name * @return */ public static Object getBean(String name){ return getApplicationContext().getBean(name); } /** * 通过class获取bean * * @param clazz * @param <T> * @return */ public static <T> T getBean(Class<T> clazz) { return getApplicationContext().getBean(clazz); } /** * 通过name,以及clazz返回指定的bean * * @param name * @param clazz * @param <T> * @return */ public static <T> T getBean(String name,Class<T> clazz) { return getApplicationContext().getBean(name, clazz); } }
