Springboot拦截器配置 Springboot拦截器配置1、拦截器配置，主要实现HandlerInterceptor接口import org.springframework.stereotype.Component; import org.springframework.web.servlet.HandlerInterceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * @description: 拦截器，配合FamilyWebConfig 配置使用 * @author: <a href="mailto:batis@foxmail.com">清风</a> * @date: 2022/3/10 22:36 * @version: 1.0 */ @Component public class LoginUserInterceptor implements HandlerInterceptor { public static ThreadLocal<Object> objUser = new ThreadLocal<>(); @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { Object loginusr = request.getSession().getAttribute("LOGIN_USR"); if(loginusr != null){ objUser.set(loginusr); //登录了才能访问 return true; }else{ //没登录，跳转去登录 return false; } } } 由于拦截器需要配合web配置使用，因此创建web配置。2、web配置主要实现WebMvcConfigurer接口import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; /** * @description: WEB配置 * @author: <a href="mailto:batis@foxmail.com">清风</a> * @date: 2022/3/10 22:40 * @version: 1.0 */ public class FamilyWebConfig implements WebMvcConfigurer { @Autowired LoginUserInterceptor loginUserInterceptor; @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(loginUserInterceptor).addPathPatterns("/**"); } }
