springboot打包成war包跨域复现问题@CrossOrigin

Question

用idea创建了一个spingboot项目，就写了一个简单的接口，类和方法上加了@CrossOrigin注解解决跨域问题。

现象：打包成jar，运行访问接口没问题。打包成war放到tomcat下面运行，接口访问提示跨域。

 

Answer 1

@Bean
    public CorsFilter corsFilterRegistration() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");

        config.setAllowedMethods(Arrays.asList("GET", "POST"));
        config.setAllowCredentials(true);
        config.setMaxAge(3600L);
        source.registerCorsConfiguration("/**",config);
        return new CorsFilter(source);
    }

 

Answer 2

你先不用跨域，测试看一下war是否打包成功，如果成功再往跨域方面想

Answer 3

response.setHeader("Access-Control-Allow-Origin", "*");

Answer 4

这些都加了的

Answer 5

@ResponseBody
@RequestMapping(value = "/test", method = {RequestMethod.POST, RequestMethod.OPTIONS})
@CrossOrigin(origins = "*")
