SpringBoot 后台服务允许跨域

1.通过 @CrossOrigin 解决跨域问题

在Controller 上增加@CrossOrigin 注解

@CrossOrigin
@RestController
@RequestMapping("/user")
@Api(value = "用户测试模块")
public class UsersController {
}

但是每个Controller 都需要增加，比较麻烦，可以增加一个BaseController，设置BaseController允许跨域

@CrossOrigin
public class BaseController {

}

@RestController
@RequestMapping("/user")
@Api(value = "用户测试模块")
public class UsersController extends BaseController {
}

2、通过CorsConfiguration 设置允许跨域

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

}
