Error 405 Request method 'POST' not supported Spring Security

Question

I am trying to implement a simple login page with Spring security. Whatever I do, I always get an error Error 405 Request method 'POST' not supported when submitting form input.

    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception

    }
}

SecurityWebApplicationInitializer.java:

import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer
{

}

part of my controller:

@RequestMapping(value = "/login", method = RequestMethod.GET)
public ModelAndView loginPage(  )
{
    return new ModelAndView("WEB-INF/views/login");
}

login.jsp:

<form action="/login" method="post">
<div>
  <label for="j_username">Username</label> <br>
  <input type="text" class="form-control" id="j_username" name="ssoId" required />
</div>
<div>
  <label for="j_password">Password</label> <br>
    <input type="password" class="form-control" id="j_password" name="password" required />
</div>

<input type="hidden" name="${_csrf.parameterName}"   value="${_csrf.token}" />

<div class="form-actions">
  <input type="submit" value="Log in" />
</div>

I think the problem is with the fact that my $(_csrf.parameterName} and ${_csrf.token} are both empty when Inspecting them. If you need any additional information, I would be happy to supply it.

Answer 1

So, I have figured it out. I did the following changes to the code in my question:

In web.xml I had to add:

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

login.jsp:

<form name='loginForm' action="/login" method='POST'>
<div>
  <label for="username">Username</label> <br>
  <input type="text" class="form-control" id="username" name="username" required />
</div>
<div>
  <label for="password">Password</label> <br>
    <input type="password" class="form-control" id="password" name="password" required />
</div>

<input type="hidden" name="${_csrf.parameterName}"   value="${_csrf.token}" />

<div class="form-actions">
  <input type="submit" value="Log in" />
</div>

SecurityConfig.java:

@Override
protected void configure(HttpSecurity http) throws Exception
{
    http.authorizeRequests()
            .antMatchers("/", "/login").permitAll()
            .antMatchers("/admin/**").hasRole("ADMIN")
            .and()
            .formLogin().loginPage("/login")
            .defaultSuccessUrl("/admin").failureUrl("/login")
            .and()
            .csrf();
}

Hope it helps someone in a similar need.
