方案一：配置CorsConfig跨域配置

package com.wxt.iforbao.base.config;

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;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class CorsConfig extends WebMvcConfigurerAdapter{
	private CorsConfiguration buildConfig() {
    	CorsConfiguration corsConfiguration = new CorsConfiguration();
    	corsConfiguration.addAllowedOrigin("*"); // 允许任何域名使用
    	corsConfiguration.addAllowedHeader("*"); // 允许任何头
    	corsConfiguration.addAllowedMethod("*"); // 允许任何方法（post、get等）
    	return corsConfiguration;
	}

	[@Bean](https://my.oschina.net/bean)
	public CorsFilter corsFilter() {
    	UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    	source.registerCorsConfiguration("/**", buildConfig()); // 对接口配置跨域设置
    	return new CorsFilter(source);
	}
}

方案二：在接口上添加@CrossOrigin注解

@CrossOrigin(origins="*",maxAge=3600)
