一共两布，第一步，创建Interceptor拦截
package com.cy.example.config;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
public class LoginInterceptor implements HandlerInterceptor {
private Logger logger = LoggerFactory.getLogger(LoginInterceptor.class);
public void postHandle(HttpServletRequest request,
HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
// TODO Auto-generated method stub
}
public void afterCompletion(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex)
throws Exception {
// TODO Auto-generated method stub
}
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
// TODO Auto-generated method stub
//获取session
HttpSession session = request.getSession(true);
logger.info("----进入登录拦截器--url："+request.getServletPath()+"-----");
if(session.getAttribute(WebConfig.LOGIN_USER) == null){
logger.info("------跳转到login页面-----");
response.sendRedirect(request.getContextPath()+"/index");
return false;
}else{
session.setAttribute(WebConfig.LOGIN_USER, session.getAttribute(WebConfig.LOGIN_USER));
return true;
}
}
}第二步，注册创建的拦截器
package com.cy.example.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
public static String LOGIN_USER = "loginUser";
public WebConfig() {
super();
}
//因为新加了拦截器，这里需要重新设置资源地址
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations(
"classpath:/static/");
registry.addResourceHandler("/templates/**").addResourceLocations(
"classpath:/templates/");
super.addResourceHandlers(registry);
}
@Override
public void configureDefaultServletHandling(
DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
// 拦截规则：除了login，其他都拦截判断,excludePathPatterns是排除拦截的路径，一个是登录验证地址，一个是登录页
registry.addInterceptor(new
LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/index","/system/user/validate");
super.addInterceptors(registry);
}
