我试图得到一个消息打印到我的网页控制台时，我点击一个按钮在我的Angular 用户界面。
到目前为止，我已经做了：
我棱角分明的一面：
按钮：

<button id="b1" mat-raised-button color="primary" type="button"(click)=displayString()>Submit</button>

我的.ts文件：

displayString(){
    this.httpClient.post('http://localhost:8080/jpmorgan/editquestionSet',{},{ responseType: "text" })
    .subscribe(response => console.log(response) );
  }

我的Spring Boot面：
springsecurityconfig.java：

@Configuration
      public class WebConfig extends WebMvcConfigurerAdapter {
          @Override
          public void addCorsMappings(CorsRegistry registry) {
              registry.addMapping("/**")
                 .allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH");
          }
      }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
            .authorizeRequests()
            .antMatchers(HttpMethod.OPTIONS, "/**")
            .permitAll()
            .anyRequest()
            .authenticated()
            .and()
            .httpBasic();
    }
    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        UrlBasedCorsConfigurationSource source = new 
    UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
        return source;
       }
}

控制器

@CrossOrigin(origins = "*")
@RestController
@RequestMapping("/jpmorgan")
public class ApplicationController {

    @Autowired
    private CompilationService compilationService;

    @RequestMapping("/editquestionSet")
    public String editquestions() {
        return "Questions Added Successfully";
    }

}

我在web控制台中遇到错误：
js:3243邮政编码http://localhost：8080/jpmorgan/editquestionset 401 core.js:1449错误httperrorresponse {标题：httpheaders，状态：401，状态文本：“确定”，url:“http://localhost：8080/jpmorgan/editquestionset“，确定：错误， …}
我想要的不是错误，而是来自spring应用程序的响应：
