Springboot入门到精通-Filter 配置 CRSF

服务端跨域处理过滤器,该过滤器需要依赖cors-filter-2.2.1.jar和java-property-utils-1.9.1.jar
 

 

package com.filter;

import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;
import com.thetransactioncompany.cors.CORSConfiguration;
import com.thetransactioncompany.cors.CORSFilter;

public class Filter0_CrossOriginResource extends CORSFilter implements javax.servlet.Filter{

		super.init(config);
	}
	
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
