本文介绍了一种使用Spring Security框架实现的自定义拦截器，该拦截器能够检查用户会话状态，若未登录则自动跳转至登录页面，同时合理配置了资源文件和登录路径的放行策略。

一：

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

public class SecurityInterceptor extends HandlerInterceptorAdapter {
	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
			throws IOException {
		HttpSession session = request.getSession(); // 判断是否已有该用户登录的session
		if (session.getAttribute("loginName") != null) {
			return true;
		} else {
			response.sendRedirect("http://localhost:8080/login.html");
			return false;
		}
	}
}

二：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebConfig implements WebMvcConfigurer {
	@Bean
	public SecurityInterceptor getSecurityInterceptor() {
		return new SecurityInterceptor();
	}

	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		InterceptorRegistration addInterceptor = registry.addInterceptor(getSecurityInterceptor());
		// 排除配置
		addInterceptor.excludePathPatterns("/css/**", "/img/**", "/js/**", "/login.html", "/user/login");
		// /拦截配置
		addInterceptor.addPathPatterns("/**");
	}
}
