// 在userdetails裏給用戶受權時,須要給定角色名 受權角色 List<GrantedAuthority> grantedAuthorityList = AuthorityUtils.createAuthorityList("ROLE_ADMIN","ROLE_PM","ROLE_DEV"); // 配置url受權驗證相關 private void configAuthorizeRequests(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers(CustomSecurityProperties.exclusivePaths) .permitAll() .antMatchers("/admin/**", "/**/delete").hasAnyRole("ADMIN") .anyRequest() .authenticated(); }
受權的時候有ROLE前綴,可是作URL的權限配置時,並無ROLE前綴。html
版本是spring-security-core-4.2.7.RELEASE.jar
源碼org.springframework.security.access.vote.RoleVoter ,類中定義了一個前綴private String rolePrefix = "ROLE_";,類中的supports方法會拿權限參數和rolePrefix進行匹配,查看是不是以ROLE_開頭。java
public boolean supports(ConfigAttribute attribute) { if ((attribute.getAttribute() != null) //這裏在驗證前綴 && attribute.getAttribute().startsWith(getRolePrefix())) { return true; } else { return false; } } public int vote(Authentication authentication, Object object, Collection<ConfigAttribute> attributes) { if(authentication == null) { return ACCESS_DENIED; } int result = ACCESS_ABSTAIN; Collection<? extends GrantedAuthority> authorities = extractAuthorities(authentication); for (ConfigAttribute attribute : attributes) { // 這裏會遍歷全部的角色值 先判斷是否有前綴 有前綴的話 則進行投票 if (this.supports(attribute)) { result = ACCESS_DENIED; // Attempt to find a matching granted authority for (GrantedAuthority authority : authorities) { if (attribute.getAttribute().equals(authority.getAuthority())) { return ACCESS_GRANTED; } } } } return result; }
第77行中會驗證受權角色信息是否之前綴開頭git
(這是一個投票器,會對當前用戶角色信息和所訪問的資源信息的權限要求進行匹配,給出 -1 0 1 這樣的投票值
