Add Spring security Java Config to Spring config - spring

Question

i'm working on a spring application lately, and i wanted to add spring security to my app.
I had a simple page containing a login form working like a charm, but when i wanted to add the spring security configuration to the app i get an error.
Here's the code of my SecurityConfig file :
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
/*#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER");
}*/
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
/*.antMatchers("/infermier*//**").hasRole("INFERMIER")
.antMatchers("/docteur*//**").hasRole("DOCTEUR")
.antMatchers("/user*//**").hasRole("USER")*/
.anyRequest().authenticated()
.and()
.formLogin()
.loginProcessingUrl("/login")
.permitAll();
}
}
And here's the log :

PS: I did added it to the MVCInitializer :
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { AppConfig.class,SecurityConfig.class};
}

Answer 1

Make sure you have spring-security-config in your classpath. Obviously it is missing at the runtime.
In such case running mvn clean install prior to running your application can fix the problem.

Answer 2

java.lang.NoClassDefFoundError ... That means a class of name XYZ has not been found on your classpath. Add spring-security-config.jar to your classpath.

Answer 3

#idursun gave me a solution and a nice explanation, there was nothing wrong with the configuration i made (it actually worked afterwards), and the problem was that the target
folder got messed up, so i cleaned it using the maven projects tool and installed everything all over again (using the same tool), and voila, everything is good

Answer 4

It was a wrong maven project packaging type, in my case:
<packaging>pom</packaging>
instead of
<packaging>war</packaging>
