Request Matcher not working to permit allowed path-CodePudding

I am following an older tutorial to implement Spring Security. Unfortunately, antMatchers is not recogzied as a method in my configuration class, so after doing some research, I believe requestMatchers method is its equivalent. However, the path (/) remains blocked without authentication. I would like to permit this.

Here is my controller:

package com.quadri.springsecurity.controllers;

import java.util.Arrays;
import java.util.List;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.quadri.springsecurity.models.Student;

@RestController
@RequestMapping("api/v1/students")
public class StudentController {

    private static final List<Student> STUDENTS = Arrays.asList(
        new Student(1, "James Bond"),
        new Student(2, "Maria Jones"),
        new Student(3, "Anna Smith")
    );

    @GetMapping(path = "{studentId}")
    public Student getStudent(@PathVariable("studentId") Integer studentId) {
        return STUDENTS.stream()
        .filter(student -> studentId.equals(student.getStudentId()))
        .findFirst()
        .orElseThrow(() -> new IllegalStateException("Student "   studentId   " does not exist!"));
    }
}

Here is my config file:

package com.quadri.springsecurity.security;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class ApplicationSecurityConfig {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests()
                .requestMatchers( "resources/**", "/").permitAll()
                .anyRequest().authenticated()
                .and()
            .httpBasic();
        
        return http.build();
    }
}

In my resources/static folder I have created a simple html page (index.html) displaying hello world. In the tutorial the RequestMapping wasn't changed, however they used .antMatcher in the config file which is not a recognized method in Spring Security at least the version I am using. Here is my POM for reference:

What is the proper way to make sure the home or "/" URL is permitted?

CodePudding user response：

You should allow index.html in the HttpSecurity request matchers as going to / is doing an auto-redirect to index.html and there is no permit rule defined for index.html giving an auth prompt. Below setting should work:

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {

    http
        .authorizeHttpRequests()
            .requestMatchers( "/resources/**", "/", "/index.html").permitAll()
            .anyRequest().authenticated()
            .and()
        .httpBasic();

    return http.build();
}
