use blog;

3. Interceptor configuration
LoginConfig
package com.guo.blog.config;
import com.guo.blog.interceptor.UserLoginInterceptor;
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 LoginConfig implements WebMvcConfigurer {
@Override
public void addInterceptors(InterceptorRegistry registry) {
//注册TestInterceptor拦截器
InterceptorRegistration registration = registry.addInterceptor(new UserLoginInterceptor());
registration.addPathPatterns("/**"); //所有路径都被拦截
registration.excludePathPatterns( //添加不拦截路径
"/", //首页路径
"/blog/toLogin", //登录路径
"/blog/login",
"/**/*.html", //html静态资源
"/**/*.js", //js静态资源
"/**/*.css" //css静态资源
);
}
}
UserLoginInterceptor
package com.guo.blog.interceptor;
import com.guo.blog.pojo.User;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import jakarta.servlet.http.HttpSession;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
public class UserLoginInterceptor implements HandlerInterceptor {
/*
* 在请求处理之前进行调用(Controller方法调用之前)
*/
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
System.out.println("执行了拦截器的preHandle方法");
try {
HttpSession session = request.getSession();
User user = (User) session.getAttribute("login");
if (user != null) {
return true;
}
response.sendRedirect(request.getContextPath() + "/blog/toLogin");
} catch (Exception e) {
e.printStackTrace();
}
return false;
//如果设置为false时，被请求时，拦截器执行到此处将不会继续操作
//如果设置为true时，请求将会继续执行后面的操作
}
/*
* 请求处理之后进行调用，但是在视图被渲染之前（Controller方法调用之后）
*/
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
System.out.println("执行了拦截器的postHandle方法");
}
/*
* 整个请求结束之后被调用，也就是在DispatchServlet渲染了对应的视图之后执行（主要用于进行资源清理工作）
*/
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
System.out.println("执行了拦截器的afterCompletion方法");
}
}
It can actually run directly here. But my project is an interceptor, if you don't want to use it, you can delete it.
specific location:
4. Front-end page display
Home index.html
login page
Enter the blog homepage
Article classification
Here you can beautify yourself. The function is realized, but it is simple and rough haha~
write an essay
This form also needs to be beautified. This is the direction I will slowly update in the future. You can continue to follow me!
5. Background management page display
Background login
Enter the main interface after successful login
blog list
user list
administrator list
Some new functions will be added to the management page in the future, such as administrator permissions, roles, super administrators and other functions.
There are also some specific data pages added to the list display.
