新建maven项目
pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>test-cors</artifactId> <version>0.0.1-SNAPSHOT</version> <name>test-cors</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
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> <meta charset="UTF-8"/> <title>Page Index</title> </head> <body> <h3>前台系统</h3> <p id="info"></p> </body> <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
