本人遇到的跨域问题，解决方式还有nginx代理，配置拦截器，ajax的jsonp,jQuery的jsonp插件等，技术有限，遇到了会继续更新
1.在接口名上添加注解
@GetMapping("/student/pdf1")
@CrossOrigin(origins = "*", allowCredentials = "true", allowedHeaders = "", methods = {})
public synchronized void studentPdf1(@RequestParam String string) {
}
2.在接口内添加
@GetMapping("/student/pdf1")public synchronized SignEntity studentPdf1(@RequestParam String string,HttpServletResponse response) {
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
System.out.println(response.getStatus());
}
3.实现addCorsMappings
@Configuration public class WebConfig implements WebMvcConfigurer { @Override public void configurePathMatch(PathMatchConfigurer configurer) { } @Override public void configureContentNegotiation(ContentNegotiationConfigurer configurer) { } @Override public void configureAsyncSupport(AsyncSupportConfigurer configurer) { } @Override public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) { } @Override public void addFormatters(FormatterRegistry registry) { } @Override public void addInterceptors(InterceptorRegistry registry) { } @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { } @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOrigins("*") .allowCredentials(true) .allowedMethods("POST, GET, OPTIONS, DELETE") .maxAge(3600 * 24); } @Override public void addViewControllers(ViewControllerRegistry registry) { } @Override public void configureViewResolvers(ViewResolverRegistry registry) { } @Override public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) { } @Override public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers) { } @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { } @Override public void extendMessageConverters(List<HttpMessageConverter<?>> converters) { } @Override public void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers) { } @Override public void extendHandlerExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers) { } @Override public Validator getValidator() { return null; } @Override public MessageCodesResolver getMessageCodesResolver() { return null; } }
4.Cors
@Bean public CorsFilter corsFilter() { final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource(); final CorsConfiguration corsConfiguration = new CorsConfiguration(); /*是否允许请求带有验证信息*/ corsConfiguration.setAllowCredentials(true); /*允许访问的客户端域名*/ corsConfiguration.addAllowedOrigin("*"); /*允许服务端访问的客户端请求头*/ corsConfiguration.addAllowedHeader("*"); /*允许访问的方法名,GET POST等*/ corsConfiguration.addAllowedMethod("*"); urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration); return new CorsFilter(urlBasedCorsConfigurationSource); }
如有补充，执经叩问；
