5655Springboot默认是禁止跨域请求的。
可以添加配置类打开：
package com.nemo.common.configs;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
/**
* Springboot跨域配置
* Created by Nemo on 3/20/2017.
*/
@Configuration
public class CorsConfig {
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("*"); // 1 允许任何域名使用
corsConfiguration.addAllowedHeader("*"); // 2 允许任何头
corsConfiguration.addAllowedMethod("*"); // 3 允许任何方法（post、get等）
return corsConfiguration;
}
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig()); // 4
return new CorsFilter(source);
}
}
