应用启动类
package com.example.testcors;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TestCorsApplication {
public static void main(String[] args) {
SpringApplication.run(TestCorsApplication.class, args);
}
}控制器
package com.example.testcors;
import org.springframework.web.bind.annotation.CookieValue;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("hello1")
public class CorsController {
@GetMapping("hello2")
public String testController(
@CookieValue(name = "testcookie") String testCookie
) {
return testCookie;
}
}配置类
package com.example.testcors;
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 WebMvcConfiguration implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowCredentials(true)
.allowedMethods("*")
.allowedOrigins("*")
.allowedHeaders("*");
}
}另建项目
前端
html文件
将jquery文件放入同目录下
<!DOCTYPE html>
<html lang="en">
<head>

<script src="jquery-3.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
// $.cookie('testcookie','test-value');
// console.log( $.cookie('testcookie'));
$.ajax({
url: 'http://test.testcors.com:8080/hello1/hello2',
type: "GET",
crossDomain: true,
xhrFields: {
withCredentials: true
},
success: function (data) {
$("#info").html("跨域访问成功:" + data);
},
error: function (data) {
$("#info").html("跨域失败!!");
},
})
</script>
</html>本地hosts配置
添加一行
127.0.0.1 test.testcors.com
浏览器使用cookie相关插件添加cookie
域名为.testcors.com
名为 testcookie
值为任意值
