spring-boot - 我想首先查看登录页面，即使任何用户想要访问任何其他页面都需要在 Spring Security 中重定向到登录页面

Question

这是示例控制器。我的问题基本上是当我输入基本网址时，它重定向到内页而不是登录页面。我想要的是。我应该怎么做才能做到这一点。

package com.sushovan.security.controller;

import javax.validation.groups.ConvertGroup;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String home() {
        return "home.jsp";
    }

    @RequestMapping("/login")
    public String loginPage() {
        return "login.jsp";
    }

    @RequestMapping("/logout-success")
    public String logoutPage() {
        return "logout.jsp";
    }
}

这是示例安全配置类。几乎所有配置都在这里完成。

package com.sushovan.security.config;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;
import org.springframework.security.web.util.matcher.AntPathRequestMatcher;
import org.springframework.util.AntPathMatcher;

@Configuration
@EnableWebSecurity
public class AppSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;
    /**This is for authentication from database**/
    @Bean
    public AuthenticationProvider authProvider() {
        DaoAuthenticationProvider provider = new DaoAuthenticationProvider();

        provider.setUserDetailsService(userDetailsService);
        //provider.setPasswordEncoder(NoOpPasswordEncoder.getInstance());//This is for not use any encryption
        provider.setPasswordEncoder(new BCryptPasswordEncoder());//This is for BCryptPasswordEncoder
        return provider;
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().disable();
        http.authorizeRequests().antMatchers("/login")
            .permitAll()
            .and()
            .formLogin()
            .loginPage("/login")
            .usernameParameter("userName").passwordParameter("password")
            .permitAll()
            .and()
            .logout().invalidateHttpSession(true)
            .clearAuthentication(true)
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
            .logoutSuccessUrl("/logout-success").permitAll();

    }
}

Answer 1

Spring 安全过滤器算法是这样工作的；网络资源受保护吗？用户认证了吗？用户是否授权？

因此，如果未通过身份验证，它将请求重定向到登录页面，这就是您想要的。

所以你应该更新你的配置方法

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.csrf().disable();
        http.authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .formLogin()
            .loginPage("/login")
            .usernameParameter("userName").passwordParameter("password")
            .permitAll()
            .and()
            .logout().invalidateHttpSession(true)
            .clearAuthentication(true)
            .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
            .logoutSuccessUrl("/logout-success").permitAll();

    }

你能试试这个，让我知道它是否有效吗？
