angular2Spring靴交叉原点cors

Question

test() {
  let jwt = localStorage.getItem('token');
  let headers = new Headers({
        'Content-Type': 'application/json; charset=utf-8',
        'Authorization': 'Bearer ' + jwt 
    });

    let options = new RequestOptions({ headers: headers });
    this.http.get('http://localhost:8080/service/events/byTeamId/1', options)
        .map((response: Response) => response.json())
        .subscribe(
            data => console.log('Response: '+data),
            err => console.log('error: '+err),
            () => console.log('Secret Quote Complete')
        );


}

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

    private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

    @Autowired
private SimpleCorsFilter simpleCorsFilter;

@Resource
private UserDetailsServiceImpl userDetailsService;

@Resource
private JwtAuthenticationProvider jwtAuthenticationProvider;

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .authorizeRequests()
                .antMatchers("/", "/home", "/login", "/register").permitAll()
                .anyRequest().authenticated()
                .and()
            .addFilterBefore(simpleCorsFilter, ChannelProcessingFilter.class)
            .addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
            .logout()
                .permitAll()
            .and().csrf().disable();

}...

我的SimpleCorsFilter如下所示：

    @Component
public class SimpleCorsFilter implements Filter {

    private final Logger log = LoggerFactory.getLogger(SimpleCorsFilter.class);

    public SimpleCorsFilter() {
        log.info("SimpleCORSFilter init");
    }

    @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", "http://localhost:4200");
        //response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me, Authorization");

        chain.doFilter(req, res);
    }

    @Override
    public void init(FilterConfig filterConfig) {
    }

    @Override
    public void destroy() {
    }

}

机智的邮递员它工作正常：

并调查了StackOverflow上发布的几个类似问题。

对我来说，它使用这个解决方案：将其添加到Spring Security配置中：

.antMatchers(org.springframework.http.HttpMethod.OPTIONS, "/service/**").permitAll()

http
.authorizeRequests()
                .antMatchers("/", "/home", "/login", "/register").permitAll()
                .antMatchers(org.springframework.http.HttpMethod.OPTIONS, "/service/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .addFilterBefore(simpleCorsFilter, ChannelProcessingFilter.class)
            .addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
            .logout()
                .permitAll()
            .and().csrf().disable();

（仍然需要jwt令牌，我多么想拥有它）
