SpringBoot 项目[若依项目禁止OPTIONS等不安全的请求] 增加 OPTIONS 不安全请求处理

若依框架禁止OPTIONS不安全请求的处理

通过Filter进行处理

• 增加filter处理器

package com.unicom.tsm.framework.config;

import org.springframework.stereotype.Component;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**

@Component
public class CorsFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res,
                         FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        // 当前只支持POST 跟GET
        response.setHeader("Access-Control-Allow-Methods",
                "POST, GET");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers",
                "Content-Type, x-requested-with, X-Custom-Header, Authorization");
         // 对OPTIONS请求进行拦截处理
        if("OPTIONS".equalsIgnoreCase(request.getMethod())){
            response.setStatus(HttpServletResponse.SC_METHOD_NOT_ALLOWED);
            ServletOutputStream outputStream = response.getOutputStream();
            outputStream.write(new String("不安全的请求".getBytes(),"utf-8").getBytes());
            outputStream.flush();
        }else {
            chain.doFilter(req, res);
        }

    }

    @Override
    public void destroy() {
    }
}

添加如上代码然后运行一下试试，本地测没问题
