springboot配置请求跨域问题

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;

/**
 * Created by myz on 2017/7/10.
 *
 * 设置跨域请求
 */
@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*"); // 1 设置访问源地址
        corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
        corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig()); // 4 对接口配置跨域设置
        return new CorsFilter(source);
    }
}

 第二种配置方法

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Component;

/**
 * Created by myz on 2017/7/10.
 *
 * 设置跨域请求
 */
@Component
public class CorsConfig implements Filter{

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
            throws IOException, ServletException {
        HttpServletResponse response=(HttpServletResponse)res;
        response.setHeader("Access-control-Allow-Origin", "*");
        response.setHeader("Access-control-Allow-Credentials", "true");
        response.setHeader("Access-control-Allow-Methods", "*");
        response.setHeader("Access-control-Max-Age", "3600");
        response.setHeader("Access-control-Allow-Headers", "Content-Type,Access-Token");
    }
    
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }


    @Override
    public void destroy() {
    }
    
}
