java如何在jboss eap 7.3上启用cors？

8 月，1 周 Questions & Answers 331

我知道这个问题被问了很多次

我有一个关于spring boot rest项目的简单war文件

使用全局cors，我能够成功地在tomcat上解析cors，但在jbos上同样的代码和配置失败

@Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedMethods("*")
                .allowedOrigins("http://localhost:9000").allowCredentials(true);
            }
        };
    }

但即使使用这种配置，jboss也会出现cors错误

那么我们是否需要额外更新jboss配置以启用cors

从这里添加xml配置

http://www.mastertheboss.com/jboss-web/jbosswebserver/how-to-configure-cors-on-wildfly

所以在我添加了上面链接中提到的过滤器之后，现在我的请求给出了404错误

我的更新版独立版。xml文件更新的代码片段

您必须配置Undertow，这是“最佳”方式，因为它还会在常规资源上添加这些标题。见http://www.mastertheboss.com/jboss-web/jbosswebserver/how-to-configure-cors-on-wildfly

找到了解决办法

实际上，问题与CORS错误无关，正如浏览器在“网络”选项卡中显示的那样。它具有误导性

首先，我从postman测试了api，当它部署在jboss上时，它给出了404错误。这是主要问题

然后我搜索并找到了如何在jboss上部署spring boot war，并找到了缺失的链接

更新-1。弹簧靴主类

与其只是添加全局cors配置，不如扩展SpringBootServletilizer

Update-2必须添加javax。pom中的servlet api依赖关系。并从spring boot starter web中排除嵌入式tomcat
