1.通过SpringSecurity方式配置
2.使用Spring提供的CorsFilter注入Bean(推荐)
3.使用注解@CrossOrigin注解(繁琐)
4.通过ResponseBodyAdvice 实现跨域
5.通过HttpServletResponse设置跨域
6.通过WebMvcConfigurer 实现跨域
1.通过SpringSecurity方式配置
@Configuration@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { // 允许跨域 http.cors().configurationSource(corsConfigurationSource()); // 省略其他代码... } // 跨域配置 private CorsConfigurationSource corsConfigurationSource() { CorsConfiguration config = new CorsConfiguration(); config.setAllowedMethods(Arrays.asList("GET", "POST"));// 支持请求方式 config.addAllowedOriginPattern("*");// 支持跨域 config.setAllowCredentials(true);// cookie config.addAllowedHeader("*");// 允许请求头信息 config.addExposedHeader("*");// 暴露的头部信息 UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", config);// 添加地址映射 return source; }} 2.使用Spring提供的CorsFilter注入Bean(推荐)
//....省略其他代码 @Bean public CorsFilter corsFilter() { CorsConfiguration config = new CorsConfiguration(); config.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE"));// 支持请求方式 config.addAllowedOriginPattern("*");// 支持跨域 config.setAllowCredentials(true);// cookie config.addAllowedHeader("*");// 允许请求头信息 config.addExposedHeader("*");// 暴露的头部信息 UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", config);// 添加地址映射 return new CorsFilter(source); }//....省略其他代码 3.使用注解@CrossOrigin注解(繁琐)
import org.springframework.web.bind.annotation.CrossOrigin;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController; @RestController@CrossOrigin(origins = "*")public class DemoController { @RequestMapping("/test") public Object test() { return "hello world"; }} 4.通过ResponseBodyAdvice 实现跨域
与第5类似
import org.springframework.core.MethodParameter;import org.springframework.http.MediaType;import org.springframework.http.server.ServerHttpRequest;import org.springframework.http.server.ServerHttpResponse;import org.springframework.web.bind.annotation.ControllerAdvice;import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice; @ControllerAdvicepublic class ResponseAdvice implements ResponseBodyAdvice { /** * 内容是否需要重写(通过此方法可以选择性部分控制器和方法进行重写) * 返回 true 表示重写 */ @Override public boolean supports(MethodParameter returnType, Class converterType) { return true; } /** * 方法返回之前调用此方法 */ @Override public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) { // 设置跨域 response.getHeaders().set("Access-Control-Allow-Origin", "*"); return body; }} 5.通过HttpServletResponse设置跨域
HttpServletResponse#setHeader("Access-Control-Allow-Origin", "*"); 6.通过WebMvcConfigurer 实现跨域
import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.CorsRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configurationpublic class CorsConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") // 所有接口 .allowCredentials(true) // 是否发送 Cookie .allowedOriginPatterns("*") // 支持域 .allowedMethods(new String[]{"GET", "POST"}) // 支持方法 .allowedHeaders("*")// 允许请求头 .exposedHeaders("*");// 暴露出去的响应头 }}
