简介
这是一个速查笔记: 在Spring Boot里配置一个登录拦截器
步骤
1. 写拦截器
@Component
public class LoginUserInterceptor implements HandlerInterceptor {
public static ThreadLocal<MemberResponseVo> loginUser = new ThreadLocal<>();
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
String uri = request.getRequestURI();
AntPathMatcher antPathMatcher = new AntPathMatcher();
boolean match = antPathMatcher.match("/order/order/status/**", uri);
boolean match1 = antPathMatcher.match("/payed/notify", uri);
if (match || match1) {
return true;
}
//获取登录的用户信息
MemberResponseVo attribute = (MemberResponseVo) request.getSession().getAttribute(LOGIN_USER);
if (attribute != null) {
//把登录后用户的信息放在ThreadLocal里面进行保存
loginUser.set(attribute);
return true;
} else {
//未登录,返回登录页面
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("<script>alert('请先进行登录,再进行后续操作!');location.href='http://auth.gulimall.com/login.html'</script>");
// session.setAttribute("msg", "请先进行登录");
// response.sendRedirect("http://auth.gulimall.com/login.html");
return false;
}
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
}
}
2. 写配置类
@Configuration
public class OrderWebConfig implements WebMvcConfigurer {
@Autowired
private LoginUserInterceptor loginUserInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(loginUserInterceptor).addPathPatterns("/**");
}
}
效果
实现了登陆拦截功能.
