不能在Spring启动数据Rest中启用CORS

Question

我需要在spring boot data rest api中启用全局CORS，以防止在从浏览器调用api时出现以下错误:http://localhost:8090/posts？user-id=1。请求的资源上没有“访问-控制-允许-来源”标头。因此，不允许访问源“http：//localhost”。“

我可以在a浏览器中键入url并接收该资源的正确get响应，但我不能从网页中的ajax调用中发出相同的调用。

@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'
}

因此，在评论中讨论了我发现的内容后，您可以在addCorsMappings方法中尝试此方法

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