提交响应后无法调用sendError（）

时间：2017-06-08 17:12:04

标签： java spring spring-mvc servlets filter

我有以下过滤器：

public class IPFilter extends GenericFilterBean {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        if ("/api/v1/auth/user".equals(((HttpServletRequest) request).getRequestURI())) {
             //skip
            chain.doFilter(request, response);
        }
        ...
    }
    ...
}

我添加if后，我看到了

我错了什么？

答案 0 :(得分：-1)

看起来应该是这样的：

public class IPFilter extends GenericFilterBean {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        if ("/api/v1/auth/user".equals(((HttpServletRequest) request).getRequestURI())) {
             //skip
            chain.doFilter(request, response);
            return; //   <--- important line
        }
        ...
    }
    ...
}
