Spring Boot 处理前端跨域问题

SpringBoot

本文介绍的只是其中的一种处理方式,啥话不说,直接上代码：

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;public class MyCorsFilter implements Filter { @Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
HttpServletRequest reqs = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin", reqs.getHeader("Origin"));
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Max-Age", "3600");
 //response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
chain.doFilter(req, res);
} @Override
public void init(FilterConfig filterConfig) {} 
@Override
public void destroy() {}
}

import com.xxx.xxx.xxx.xxx.filter.MyCorsFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configurationpublic class CorsConfigure { @Bean
public FilterRegistrationBean test() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new MyCorsFilter());
registration.addUrlPatterns("/*");
registration.addInitParameter("paramName", "paramValue");
registration.setName("MyFilter");
registration.setOrder(1);
return registration;
}
}
