I'm trying to learn Java Spring and doing exactly like here: https://spring.io/guides/gs/securing-web/

But my IDE says "cannot resolve 'security' symbol" while importing config. I'm using the same version of spring and have the same code. I don't know what is wrong.

package com.github.SpringSite.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; 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.provisioning.InMemoryUserDetailsManager; @Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/", "/home").permitAll() .anyRequest().authenticated() .and() .formLogin() .loginPage("/login") .permitAll() .and() .logout() .permitAll(); } @Bean @Override public UserDetailsService userDetailsService() { UserDetails user = User.withDefaultPasswordEncoder() .username("user") .password("password") .roles("USER") .build(); return new InMemoryUserDetailsManager(user); } }

My pom.xml

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.github</groupId> <artifactId>SpringSite</artifactId> <version>0.0.1-SNAPSHOT</version> <name>SpringSite</name> <description>Simple website using Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-test</artifactId> <scope>test</scope> </dependency> </dependencies> <properties> <java.version>1.8</java.version> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

I would also be grateful for the recommendation of a good guide to learn spring.

Reset to default

It looks that your current spring-security dependency is only for test scope.

If we follow the tutorial, it states that you have to add the following dependency for WebSecurityConfig:

<dependencies> ... <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> ... </dependencies>

Note that the scope is not set here, i.e. it will be the default scope, which is compile.

You may need to manually re-import the maven project after changing dependencies: Manually re-import maven project in IntelliJ IDEA

After re-importing, the dependencies in pom.xml shouldn't be displayed as red.

Slight update

To be 146% sure, here is my pom.xml that works:

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.springframework</groupId> <artifactId>gs-securing-web</artifactId> <version>0.1.0</version> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> </dependencies> <properties> <java.version>1.8</java.version> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

Update 2 - fix of actual current problem

Actually the problem (as well as in the question text itself) is just a missing import of HttpSecurity class in WebSecurityConfig.

So adding 

import org.springframework.security.config.annotation.web.builders.HttpSecurity;

will make the code compile and SpringSiteApplication start.

Update 3 - what was the REAL problem after we investigated it via TeamViewer.

The Spring dependencies haven't been downloaded, since the computer had no access to central maven repo (https://repo.maven.apache.org/maven2). After disabling Windows firewall, the connections started to work.

IDEA was too slow when updating repo indexes, but a command-line mvn install helped to finally download the libraries. After it, the IDEA started to show the imported classes as well.

I added this dependency and clicked "Import changes". Still the same issue "Error:(5, 72) java: package org.springframework.security.config.annotation.web.configuration does not exist". It can not resolve "security" symbol.
@Eliro could you please upload your project to github to make it possible to look at it?
@Eliro because I've done it exactly by tutorial, re-imported maven, and WebSecurityConfig compiles now. I've updated the answer with the updated pom.xml.
@Eliro Thank you. I've cloned it. Actually in your file import for HttpSecurity is missing in WebSecurityConfig. Add this to imports in WebSecurityConfig: import org.springframework.security.config.annotation.web.builders.HttpSecurity;
In my case, dependency was downloaded in local repo but, IDEA was too slow when updating repo indexes. I just restarted the Intellij & it worked for me. Thanks
