这里是主要的类，所有的要求看起来都很好，我使用的是org.springframework. Boot release 1.5.7.RELEASE

package webroot.websrv.auth.config;
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Autowired
    private JwtAuthenticationEntryPoint unauthorizedHandler;
    @Autowired
    private UserDetailsService userDetailsService;
    @Autowired
    public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                .userDetailsService(userDetailsService)
                .passwordEncoder(passwordEncoder());
    }
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    @Bean
    public JwtAuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
        return new JwtAuthenticationTokenFilter();
    }
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
                .csrf().disable()
                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                .antMatchers(
                        HttpMethod.GET,
                        "/",

                        "/**/*.css",
                        "/**/*.js"

        httpSecurity.headers().cacheControl();
    }
}

型
以及：

package webroot.websrv;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WebcliApplication {
    public static void main(String[] args) {
        SpringApplication.run(WebcliApplication.class, args);
    }
}

型
使用Maven或Gradle返回相同的问题。所有注解和包名称似乎都是必需的。
