如何解决带有角数字格式Cors错误的Spring requestParam？

开发过程中遇到带有角数字格式Cors错误的Spring requestParam的问题如何解决？下面主要结合日常开发的经验，给出你关于带有角数字格式Cors错误的Spring requestParam的解决方法建议，希望对你解决带有角数字格式Cors错误的Spring requestParam有所启发或帮助；

所以我试图用 2 个参数作为数字向这个端点发出一个发布请求......我正确地获得了参数......发布时我得到从源 'http://localhost:4200' 访问 XMLhttp request at 'http://localhost:8080/API/user/addCartItem' 已被 CORS 策略阻止：对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。错误 ... 当我从邮递员那里应用相同的方法时，everythink 就可以正常运行。

    @PreAuthorize("hasAnyRole('RolE_admin','RolE_USER')")
    @requestMapPing(value = "/addCartItem/{CartID}{productID}",method = requestMethod.POST )
    public List<CartItem> addCartItem(@requestParam Long cartID,@requestParam Long productID) {
        return cartservice.addCartItem(cartID,productID);
    }

  addCartItem(cartID:number,productID:number):Observable<any>{
    const httpParams = new httpParams({
      fromObject:{
        cartID,productID,}
    })
    return this.httpClIEnt.post('http://localhost:8080/API/user/addCartItem',{ httpParams })
  }

这是安全配置类

@EnableWebMvc
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
  prePostEnabled = truE)
public class SecutiryConfig extends WebSecurityConfigurerAdapter {
    @autowired
    UserDetailsserviceImpl userDetailsservice;
    @autowired 
    private AuthEntryPointJwt unauthorizedHandler;
    @Bean
    public AuthTokenFilter authenticationJwtTokenFilter() {
        return new AuthTokenFilter();
    }
    @OverrIDe
    public voID configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder.userDetailsservice(userDetailsservicE).passwordEncoder(passwordEncoder());
    }
    @Bean 
    @OverrIDe
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    @Bean
    public passwordEncoder passwordEncoder() {
        return new BCryptpasswordEncoder();
    }
    @OverrIDe
    protected voID configure(httpSecurity http) throws Exception {
        http.cors().and().csrf().disable()
            .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
            .authorizerequests().antMatchers("/API/auth/**").permitAll()
            .antMatchers("/API/admin/**").permitAll()
            .antMatchers("/API/user/**").permitAll()
            .antMatchers("/API/public/**").permitAll()
            .anyrequest().authenticated();
        http.addFilterBefore(authenticationJwtTokenFilter(),UsernamepasswordAuthenticationFilter.class);
    }
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @OverrIDe
            public voID addCorsmapPings(CorsRegistry registry) {
                 registry.addMapPing("/**") 
                 .allowedMethods("GET","POST","PUT","deletE")
                 .allowedheaders("*")
                 .allowedOrigins("*");
            }
        };
    }
