重现步骤

        Filter autoTypeBeforeHandler = JSONReader.autoTypeFilter(
                // 按需加上需要支持自动类型的类名前缀，范围越小越安全
                "org.springframework.security.core.authority.SimpleGrantedAuthority"
        );
        String attr = "{\"@type\":\"java.util.Collections$UnmodifiableMap\",\"java.security.Principal\":{\"@type\":\"org.springframework.security.authentication.UsernamePasswordAuthenticationToken\",\"authenticated\":true,\"authorities\":[{\"@type\":\"org.springframework.security.core.authority.SimpleGrantedAuthority\",\"authority\":\"ROLE_ADMIN\"}],\"details\":{\"@type\":\"org.springframework.security.web.authentication.WebAuthenticationDetails\",\"remoteAddress\":\"127.0.0.1\",\"sessionId\":\"38220AEDC251E5CE7F45344BCA805C89\"},\"name\":\"user\",\"principal\":{\"@type\":\"org.springframework.security.core.userdetails.User\",\"accountNonExpired\":true,\"accountNonLocked\":true,\"authorities\":Set[{\"@type\":\"org.springframework.security.core.authority.SimpleGrantedAuthority\",\"authority\":\"ROLE_ADMIN\"}],\"credentialsNonExpired\":true,\"enabled\":true,\"username\":\"user\"}},\"org.springframework.security.oauth2.core.endpoint.OAuth2AuthorizationRequest\":{\"@type\":\"org.springframework.security.oauth2.core.endpoint.OAuth2AuthorizationRequest\",\"additionalParameters\":{\"@type\":\"java.util.Collections$UnmodifiableMap\"},\"attributes\":{\"@type\":\"java.util.Collections$UnmodifiableMap\"},\"authorizationRequestUri\":\"http://127.0.0.1:9000/oauth2/authorize?response_type=code&client_id=messaging-client&scope=message.read&redirect_uri=http://127.0.0.1:8000/login/oauth2/code/messaging-client-oidc\",\"authorizationUri\":\"http://127.0.0.1:9000/oauth2/authorize\",\"clientId\":\"messaging-client\",\"grantType\":{\"value\":\"authorization_code\"},\"redirectUri\":\"http://127.0.0.1:8000/login/oauth2/code/messaging-client-oidc\",\"responseType\":{\"value\":\"code\"},\"scopes\":Set[\"message.read\"]},\"state\":\"Ahvv87vejITg_FgjAtcGUKMw_G_aZIS1fbdD_mcgXFg=\"}";
        Map<String, Object> attrMap = JSON.parseObject(attr, Map.class, autoTypeBeforeHandler);
        OAuth2AuthorizationRequest o = (OAuth2AuthorizationRequest) attrMap.get(OAuth2AuthorizationRequest.class.getName());
        System.out.println(o);

期待的正确结果

期望序列化为@type中的对象

问题找到了，但是toJSONString的json是这个格式，为啥读取的时候报错呢"authorities":Set[{"@type":"org.springframework.security.core.authority.SimpleGrantedAuthority","authority":"ROLE_ADMIN"}]

[TsukasaHwan]
