【问题描述】：

这是我花了几个小时尝试解决它后无法弄清楚的。我正在研究使用 java 配置的 spring 安全性。我想出了以下异常，但不知道我应该做什么。

安全配置是

@Configuration
@EnableWebSecurity
public class AppSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/allmessages*").hasAnyRole("USER", "ANONYMOUS")
                .antMatchers("/postmessages*").hasRole("USER")
                .antMatchers("/deletemessages*").hasRole("ADMIM")
            .and()
                .httpBasic();

    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("tadtdab").password("tadtab").authorities("ROLE_ADMIN","ROLE_USER")
                .and().withUser("tadi").password("tadi").authorities("ROLE_USER");
    }
}

【解决方案1】：

我遇到了同样的问题，在阅读这篇文章后我找到了答案：它在堆栈跟踪中：如果你转到消息的末尾，你可以找到这个：

Hint try extending WebSecurityConfigurerAdapter

所以我刚刚找到了我的 webSecurityConfig 类并添加了

extends WebSecurityConfigurerAdapter

而且我的服务器正常启动
