带有Spring靴的“访问控制允许来源”

spring-boot

我有一个简单的spring boot服务在调用数据库的docker端口8080上暴露的容器中运行mysql

当我击中localhost:8080/blogs我回来[{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]

当我直接在浏览器中点击它时,它的工作就很好。但是,当我从中尝试时,jQuery我得到了正常Access-Control-Allow-Origin

这是我的Spring Boot服务:

@SpringBootApplication
@RestController
public class ChrisboltonServiceApplication {

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

@Autowired
private JdbcTemplate jdbcTemplate;

@CrossOrigin
@RequestMapping(path="/blogs")
public @ResponseBody Iterable<ChrisBolton> getAllUsers() {
    List<ChrisBolton> result = jdbcTemplate.query(
            "SELECT * FROM blog",
            (rs, rowNum) -> new ChrisBolton(rs.getString("author"), 
                                               rs.getString("title"), 
                                               rs.getString("content"), 
                                               rs.getDate("date"))
    );

    return result;
}
}

这是我的jQuery

$.ajax({
  url: "http://localhost:8080/blogs",
  crossDomain: true
}).done(function(data) {

  console.log(data);
});

但我仍然收到此错误:

XMLHttpRequest cannot load http://localhost:8080/blogs. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.

我曾尝试这种通过添加@CrossOrigingetAllUsers()方法和我在类级别都试过了。我还查看了此内容,因为我在port上运行了UI 3000。但是那个联系不是特定于春天的。

编辑

添加我的请求标头:

GET /blogs HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Accept: */*
Origin: http://localhost:3000
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) 
AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 
Safari/537.36
Referer: http://localhost:3000/
Accept-Encoding: gzip, deflate, br
Accept-Language: en-US,en;q=0.8

网络标签(Chrome)中的响应:

[{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]

因此,看来我正在“网络”标签中找回数据。但是,我console.log(data)生产Access-Control-Allow-Origin

尝试将其添加到您的应用程序:

@SpringBootApplication
@RestController
public class ChrisboltonServiceApplication {

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

...

另外,请尝试crossDomain: true从中删除$.ajax()
