typescript与springboot跨域请求

//在项目中添加跨域请求具体配置

@Configuration

public class CorsConfig {

    private CorsConfiguration buildConfig() {

        CorsConfiguration corsConfiguration = new CorsConfiguration();

        corsConfiguration.addAllowedOrigin("*");//设置访问源地址

        corsConfiguration.addAllowedHeader("*");//设置访问源请求头

        corsConfiguration.addAllowedMethod("*");//设置访问源请求方法（get、post等）

        return corsConfiguration;

    }

    @Bean

    public CorsFilter corsFilter() {

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

        source.registerCorsConfiguration("/**", buildConfig());// 对接口配置跨域设置

        return new CorsFilter(source);

    }

}

ts和html部分

@Component({

  selector: 'page-home',

  templateUrl: 'home.html'

})

export class HomePage {

  listData: Object;

  constructor(public navCtrl: NavController,public http:Http) {

  }

  printText(){

    this.http.request('http://127.0.0.1:8080/institutions/hello')

    .subscribe((res: Response) => {

      this.listData = res.json();

      console.log(this.listData);

    });

  }

}
