Question

我正在使用Spring Boot 2.0.2，我的项目中有spring-starter-web和spring-data-jpa，我暂时不使用Spring Security。我创建了RestControllers并为其添加了@CrossOrigin批注，并尝试使用此代码为我的角度应用启用CORS

@Bean
public WebMvcConfigurer corsConfigurer() {

    return new WebMvcConfigurer() {

        @Override
        public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")..allowedOrigins("*").allowedMethods("GET","POST","DELETE","PATCH","OPTIONS");
                }
            }
        };

}

但是仍然从我的角度应用程序中收到CORS错误

Answer 1

尝试类似这样的方法：创建一个名为 CorsConfiguration 或任何名称

的新类

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfiguration implements WebMvcConfigurer {

private static final String HTTP_LOCALHOST_4200 = "http://localhost:4200";
private static final String GET = "GET";
private static final String POST = "POST";
private static final String PUT = "PUT";
private static final String DELETE = "DELETE";
private static final String HEAD = "HEAD";

@Override
public void addCorsMappings(CorsRegistry registry) {

    registry.addMapping("/**")
            .allowedOrigins(
                    HTTP_LOCALHOST_4200).allowedMethods(GET, POST, PUT, DELETE, 
HEAD).allowCredentials(true);
}
}

将Spring Boot与angular一起使用时遇到CORS策略错误
