// 在userdetails里给用户授权时,需要给定角色名 授权角色
List<GrantedAuthority> grantedAuthorityList = AuthorityUtils.createAuthorityList("ROLE_ADMIN","ROLE_PM","ROLE_DEV");
// 配置url授权验证相关
private void configAuthorizeRequests(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers(CustomSecurityProperties.exclusivePaths)
.permitAll()
.antMatchers("/admin/**", "/**/delete").hasAnyRole("ADMIN")
.anyRequest()
.authenticated();
}
授权的时候有ROLE前缀,但是做URL的权限配置时,并没有ROLE前缀。
版本是spring-security-core-4.2.7.RELEASE.jar
源码org.springframework.security.access.vote.RoleVoter ,类中定义了一个前缀private String rolePrefix = "ROLE_";,类中的supports方法会拿权限参数和rolePrefix进行匹配,查看是否是以ROLE_开头。
public boolean supports(ConfigAttribute attribute) {
if ((attribute.getAttribute() != null)
//这里在验证前缀
&& 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) {
// 这里会遍历所有的角色值 先判断是否有前缀 有前缀的话 则进行投票
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行中会验证授权角色信息是否以前缀开头
(这是一个投票器,会对当前用户角色信息和所访问的资源信息的权限要求进行匹配,给出 -1 0 1 这样的投票值
投票器参考:https://blog.csdn.net/tjyyyangyi/article/details/79413307
