Spring Boot：CORS问题

spring-boot

我正在使用Spring Boot版本2.0.2Release。下面是我的安全配置

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
        prePostEnabled = true,
        securedEnabled = true,
        jsr250Enabled = true)
@ComponentScan("com.mk")
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationProvider myAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.cors().configurationSource(corsConfigurationSource())
                .and()
                .csrf().disable()
                .anonymous().and()
                .authorizeRequests()
                .antMatchers(HttpMethod.GET,"/index.html").permitAll()
                .antMatchers(HttpMethod.POST,"/login").permitAll()
                .antMatchers(HttpMethod.GET,"*").authenticated()
                .and().httpBasic();
    }
    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("GET","POST"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

由于CORS的问题，我无法调用任何API（包括login是allowAll）。

在浏览器上，我得到了（它与Postman一起使用，因为未在其中进行CORS检查）

无法加载http：// localhost：8080 /
myurl：对预检请求的响应未通过访问控制检查：所请求的资源上没有’Access-
Control-Allow-Origin’标头。因此，不允许访问源’ http：//
localhost：4200 ‘。响应的HTTP状态码为403。

尽管Spring安全性提供了一种在http configurer中配置CORS的方法，但是有一种更加干净的方法可以将CORS过滤器添加到应用程序中，

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class MyCORSFilter implements Filter {


@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

    HttpServletRequest request = (HttpServletRequest) req;
    HttpServletResponse response = (HttpServletResponse) res;

    response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
    response.setHeader("Access-Control-Allow-Credentials", "true");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

    chain.doFilter(req, res);
}

@Override
public void init(FilterConfig filterConfig) {
}

@Override
public void destroy() {
}

}

对过滤器进行最高优先级排序可确保MyCORSFilter实现javax.servlet.Filter是链中的第一个实现。希望这可以帮助
