CORS跨域问题

1,上代码

    

CORSInterceptor类:

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * 跨域拦截
 * create by mcs
 */

@Component
public class CORSInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        //添加跨域CORS
        String Origin = request.getHeader("Origin");
        response.setHeader("Access-Control-Allow-Origin", Origin);
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Cache-Control, Pragma, Origin, Authorization, Content-Type, X-Requested-With , Set-Cookie, X-CSRF-Token, Accept, Accept-Version, Content-Length, Content-MD5, Date, X-Api-Version");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        return true;
    }
}

WebConfigTest类:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

/**
 * 启用拦截器
 * create by mcs
 */

public class WebConfigTest extends WebMvcConfigurerAdapter {
    @Autowired
    private CORSInterceptor corsInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(corsInterceptor);
    }


}
