spring-boot使用Filter
Filter是J2EE提供的过滤器，在spring-boot如何使用呢？
需要用spring注解标签@WebFilter对filter类进行注解，具体代码如下
@WebFilter(filterName = "ScuvcLoginFilter", urlPatterns = "/scuvc/*")
public class ScuvcLoginFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
//do something...
// 通过判断如果没有问题就继续执行，如果有问题可以通过response.sendRedirect()的方式进行跳转
filterChain.doFilter(servletRequest, servletResponse);
}
@Override
public void destroy() {
}
}
