由于对第一次使用spirngboot遇到了很多问题，springboot支持跨域请求的配置在网上找到了很多配置，但都是不能使用，后来仔细学习了解，原来是没有配配置 @WebFilter 过滤路径
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Slf4j
@WebFilter(filterName="corsFilter",urlPatterns="/*")
public class CorsFilter implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
log.info("进入跨域过滤器--------------------------------------------------------------------------");
HttpServletResponse response = (HttpServletResponse) res;
HttpServletRequest reqs = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin",reqs.getHeader("Origin"));
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
chain.doFilter(req, res);
}
@Override
public void init(FilterConfig filterConfig) {
}
@Override
public void destroy() {
}
}
