java - 'springSecurityFilterChain' 抛出 java.lang.NullPointerException

转载作者：行者123 更新时间：2023-12-01 14:33:51

当我运行我的项目时，我得到一个 nullpointerexception。

我几乎查看了所有与这种由“springSecurityFilterChain”引起的空指针异常相关的 stackoverflow 帖子，但似乎无法修复此错误。

                //上がnullなので新規トークンクラスの作成
                DefaultOAuth2AccessToken newToken = new DefaultOAuth2AccessToken(oAuthDetails.getTokenValue());
                //新しくトークンを入れる。facebookでログイン成功したらtokenvalueが飛ばされる。
                tokenStore.storeAccessToken(newToken, oAuth);
            }
            return oAuth;
    }

}


@EnableOAuth2Sso
public class FacebookConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/products**", "/login**", "/webjars/**")
                .permitAll()
                .anyRequest()
                .authenticated()
                .and().logout().logoutSuccessUrl("/").permitAll().deleteCookies().invalidateHttpSession(true)
                .and().csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    }
}

我不完全确定它是否能立即解决您的问题，但将配置和 Controller /服务方法放在同一个类中绝不是一个好主意。
