'Access-Control-Allow-Origin' with spring boot
提问by Chris Bolton
I have a simple spring bootservice running in a dockercontainer exposed on port 8080that is calling a mysqldatabase.
我spring boot在调用数据库的docker端口8080上公开的容器中运行了一个简单的服务mysql。
When I hit localhost:8080/blogs, I get back [{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]
当我击中时localhost:8080/blogs，我回来了[{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]
This is working just fine when I hit it directly in the browser. However, when I try it from jQueryI am getting the normal Access-Control-Allow-Origin.
当我直接在浏览器中点击它时，这工作得很好。但是，当我尝试它时，jQuery我得到了正常的Access-Control-Allow-Origin.
Here is my spring boot service:
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;
}
}
Here is my jQuery:
这是我的jQuery：
$.ajax({
url: "http://localhost:8080/blogs",
crossDomain: true
}).done(function(data) {
console.log(data);
});
But I am still getting this error:
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.
I have tried thisby adding the @CrossOriginto the getAllUsers()method and I have tried at the class level. I have also looked at thisbecause I am running my UI on port 3000. But that link is not spring specific.
我已经通过在方法中添加来尝试这个，并且我已经在类级别尝试过。我也看过这个，因为我在 port 上运行我的 UI 。但该链接不是特定于 spring 的。@CrossOrigingetAllUsers()3000
EDIT
编辑
Adding my request headers:
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
Response in network tab (Chrome):
网络选项卡（Chrome）中的响应：
[{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]
[{"author":"Christopher Bolton","title":"Test Title 1","content":"This is some content","date":"2017-08-29"}]
So it looks like I am getting data back in the network tab. However, my console.log(data)produces the Access-Control-Allow-Origin
所以看起来我正在网络选项卡中取回数据。然而，我console.log(data)生产的Access-Control-Allow-Origin

Try adding this to your application:
尝试将其添加到您的应用程序中：
@SpringBootApplication
@RestController
public class ChrisboltonServiceApplication {
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*");
}
};
}
...
Also, try removing the crossDomain: truefrom the $.ajax().
另外，尝试crossDomain: true从$.ajax().

You can add @CrossOrigin("http://localhost:8080")to proper method if you want :8080to allow request there. It's a simple config for one endpoint/controller. You can use variable there too for customization later of course.
@CrossOrigin("http://localhost:8080")如果您想:8080在那里允许请求，您可以添加到适当的方法。这是一个端点/控制器的简单配置。当然，您也可以在那里使用变量进行自定义。
