tomcat服务器提供的接口，不能在其他域中访问的时候，需要增 Access-Control-Allow-Origin:*
以下操作均在需要被访问的项目中设置
1、编写拦截器代码
package com.soft.filter;
/**
* Created by Administrator on 2017/2/6.
*/
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class CORSFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletResponse httpRespOnse= (HttpServletResponse) servletResponse;
httpResponse.addHeader("Access-Control-Allow-Origin", "*");
filterChain.doFilter(servletRequest, servletResponse);
}
@Override
public void destroy() {
}
}
2、配置web.xml
CorsFilter com.omiaozu.manager.filter.CORSFilter CorsFilter /*
