無法在彈簧啓動數據休息時啓用CORS

Question

我需要在我的彈簧啓動數據休息API中啓用全局CORS，以防止在我從瀏覽器調用我的api時出現以下錯誤： http://localhost:8090/posts?user-id=1。請求的資源上沒有「Access-Control-Allow-Origin」標題。因此不允許訪問'Origin'http://localhost'。'。

我可以在瀏覽器中輸入url並獲得該資源的正確獲取響應，但我無法通過網頁中的ajax調用進行相同的調用。

任何想法，我即將失蹤？

我的代碼和配置低於：

@SpringBootApplication 
@EnableAutoConfiguration 
@EnableJpaRepositories 
@EnableWebMvc 
public class Application { 

public static void main(String[] args) { 
    SpringApplication.run(Application.class, args); 

} 

@Bean 
public WebMvcConfigurer corsConfigurer() { 

    return new WebMvcConfigurerAdapter() { 
     @Override 
     public void addCorsMappings(CorsRegistry registry) { 
      registry.addMapping("/**"); 
     } 
    }; 
} 

@Bean 
public CommandLineRunner demo(UserRepository userRepository, PostRepository postRepository, 
           CommentRepository commentRepository, EventRepository eventRepository, VenueRepository venueRepository) { 
    return (args) -> { 

     User user = new User("fsdsdfsd","sdsdsds","121212"); 
     userRepository.save(user); 

     Venue venue = new Venue("dsaesrdfddgd","aerttyhyyty","yyyyyyyyyyyyyy"); 
     venueRepository.save(venue); 

     Event event = new Event("dsaesrdfddgd","aerttyhyyty","yyyyyyyyyyyyyy",venue,user); 
     eventRepository.save(event); 

     Post post = new Post("some posts are funny. Some are not.",user, event); 
     postRepository.save(post); 

     Comment comment = new Comment("commmentntnrnejfnerfdgdfgdfdt", user, post); 
     commentRepository.save(comment); 
    }; 
} 

}

@RepositoryRestResource 
public interface PostRepository extends PagingAndSortingRepository<Post, Long> { 


Page<Post> readBydeletedIsFalseOrderByCreated(Pageable pageRequest); 

@CrossOrigin 
Post readByIdAndDeletedIsFalse(Long postId); 

}

buildscript { 
repositories { 
    mavenCentral() 
} 
dependencies { 
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.6.RELEASE") 
} 
} 

apply plugin: 'java' 
apply plugin: 'war' 
apply plugin: 'eclipse' 
apply plugin: 'idea' 
apply plugin: 'spring-boot' 

jar { 
    baseName = 'project' 
    version = '0.1.0' 
} 

war { 
    baseName = 'project' 
    version = '0.1.0' 
} 


repositories { 
    mavenCentral() 
} 

sourceCompatibility = 1.8 
targetCompatibility = 1.8 

dependencies { 
    compile("org.springframework.boot:spring-boot-starter-data-rest") 
    compile("org.springframework.boot:spring-boot-starter-data-jpa") 
    compile("com.h2database:h2") 
} 

task wrapper(type: Wrapper) { 
    gradleVersion = '2.3' 
} 

Answer 1

在評論中我發現了什麼，你可以在你addCorsMappings試試這個方法經過討論所以

registry.addMapping("/**").allowedOrigins("http://localhost:8090") 
          .allowedMethods("PUT", "DELETE", "GET", "POST"); 

Answer 2

嘗試在全局配置添加此：

registry.addMapping("/**").allowedOrigins("*");

Answer 3

好加入這個bean幫助

@Bean 
public FilterRegistrationBean corsFilter() { 
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); 
    CorsConfiguration config = new CorsConfiguration(); 
    config.setAllowCredentials(true); 
    config.addAllowedOrigin("*"); 
    config.addAllowedHeader("*"); 
    config.addAllowedMethod("GET"); 
    source.registerCorsConfiguration("/**", config); 
    FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source)); 
    bean.setOrder(0); 
    return bean; 
} 

滑稽足夠春天不允許CORS支持使用以下bean的spring引導數據休息端點。但是，它可以像開發人員創建的其他自定義端點那樣正常工作。

@Bean 
public WebMvcConfigurer corsConfigurer() { 

    return new WebMvcConfigurerAdapter() { 
     @Override 
     public void addCorsMappings(CorsRegistry registry) { 
      registry.addMapping("/**").allowedOrigins("*").allowedMethods("GET"); 
     } 
    }; 
}
