SpringBoot解决跨域问题

方案一

在请求的方法或者Controller上加上@CrossOrigin注解，如下

@CrossOrigin
@RequestMapping("attention")
public ResponseVO auditAttention(@Context HttpServletRequest request, @Context HttpServletResponse response) { 
}

方案二

配置一个全局的跨域管理器

@Configuration
public class CORSConfiguration { 
    @Bean
    public WebMvcConfigurer corsConfigurer() { 
        return new WebMvcConfigurerAdapter() { 
            @Override
            public void addCorsMappings(CorsRegistry registry) { 
                registry.addMapping("/**")
                        .allowedOrigins("*")
                        .allowedMethods("GET", "POST", "DELETE", "PUT", "OPTIONS")
                        .allowCredentials(false).maxAge(3600);
            }
        };
    }
}

其他尝试过的无效的方案

方案1
response.addHeader("Access-Control-Allow-Origin", "*");
response.addHeader("Access-Control-Allow-Credentials", "true");
response.addHeader("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");
response.addHeader("Access-Control-Allow-Headers", "Content-Type,X-CAF-Authorization-Token,sessionToken,X-TOKEN");
方案2
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, HEAD");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "access-control-allow-origin, authority, content-type, version-info, X-Requested-With");
