使用Spring Security时，Security默认会拦截WebSocket连接。 

最近项目中使用Spring Security进行验证过滤，后来发现Spring Security拦截http的同时也拦截了websocket，导致websocket无法连接，尝试各种方法，包括

configure(HttpSecurity httpSecurity)

中各种配置还是无效，后来经过尝试，最终发现，在

void configure(WebSecurity webSecurity)中设置即可：

@Override
    public void configure(WebSecurity webSecurity){
        webSecurity.ignoring().antMatchers(
                "/ws/**"
        );
    }

完整代码：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    UserDetailsService userDetailService;

    @Autowired
    private RestfulAccessDeniedHandler restfulAccessDeniedHandler;
    @Autowired
    private RestAuthenticationEntryPoint restAuthenticationEntryPoint;
    
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        //super.configure(http);
        // TODO Auto-generated method stub
        httpSecurity.csrf()// 由于使用的是JWT，我们这里不需要csrf
                .disable()
//		.sessionManagement()// 基于token，所以不需要session
//		.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
//		.and()

                .authorizeRequests()
                .antMatchers(HttpMethod.GET, // 允许对于网站静态资源的无授权访问
                        "/",
                        "/*.html",
                        "/favicon.ico",
                        "/**/*.html",

                        "/**/pmq/public"
                )
                .permitAll()
                .antMatchers("/user/login", "/task/optional_data_info")// 对登录注册要允许匿名访问
                .permitAll()
                .antMatchers(HttpMethod.OPTIONS)//跨域请求会先进行一次options请求
                .permitAll()
                //        .antMatchers("/**")//测试时全部运行访问
                //        .permitAll()
                .anyRequest()// 除上面外的所有请求全部需要鉴权认证
                .authenticated();
        // 禁用缓存
        httpSecurity.headers().cacheControl();

        // 添加JWT filter
        httpSecurity.addFilterBefore(jwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);
        //添加自定义未授权和未登录结果返回
        httpSecurity.exceptionHandling()
                .accessDeniedHandler(restfulAccessDeniedHandler)
                .authenticationEntryPoint(restAuthenticationEntryPoint);
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //super.configure(auth);
        auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());
    }

    //忽略websocket拦截
    @Override
    public void configure(WebSecurity webSecurity){
        webSecurity.ignoring().antMatchers(
                "/ws/**"
        );
    }


    @Bean
    public UserDetailsService userDetailsService()

        return new PhotovoltaicUserDetailsService();
