Spring Boot - JDBC Authentication With H2 Console

[Last Updated: Jun 7, 2018]

In the last example we saw how to enable JDBC security using H2 database. In following example we will see how to configure H2 web console when security is enabled.




Configuration class

public class ExampleMain {

  public WebSecurityConfigurerAdapter webSecurityConfig(DataSource dataSource) {
      return new WebSecurityConfigurerAdapter() {
          protected void configure(HttpSecurity http) throws Exception {
                  .antMatchers("/h2-console/**").hasRole("ADMIN")//allow h2 console access to admins only
                  .anyRequest().authenticated()//all other urls can be access by any authenticated role
                  .and().formLogin()//enable form login instead of basic login
                  .and().csrf().ignoringAntMatchers("/h2-console/**")//don't apply CSRF protection to /h2-console
                  .and().headers().frameOptions().sameOrigin();//allow use of frame to same origin urls

          protected void configure(AuthenticationManagerBuilder builder) throws Exception {

  public static void main(String[] args) {;

In above configuration we have allowed access to the URIs starting with /h2-console/ to the ADMIN role only. We have also disabled CSRF protection for /h2-console/** and allowed frame use (H2 console uses <frame></frame>) if the request come from the same origin (i.e. localhost:8080 in our example). See also X-Frame-Options.

SQL scripts


create table users(
	username varchar_ignorecase(50) not null primary key,
	password varchar_ignorecase(200) not null,
	enabled boolean not null

create table authorities (
	username varchar_ignorecase(50) not null,
	authority varchar_ignorecase(50) not null,
	constraint fk_authorities_users foreign key(username) references users(username)


insert into users (username, password, enabled) values ('bob', '{noop}123', true);
insert into authorities (username, authority) values ('bob', 'ROLE_USER');

insert into users (username, password, enabled) values ('sara', '{noop}234', true);
insert into authorities (username, authority) values ('sara', 'ROLE_ADMIN');

In data.sql script we used {noop} to indicate that no password encoder (NoOpPasswordEncoder) should be used as we also did not specify any password encoder in our configuration above.

MVC controller

public class AppController {

  public String handler(ModelMap model, HttpServletRequest request) {
      Authentication auth = SecurityContextHolder.getContext()
      model.addAttribute("uri", request.getRequestURI());
      model.addAttribute("user", auth.getName());
      model.addAttribute("roles", auth.getAuthorities());
      return "app";

Thymeleaf view


<!DOCTYPE html>
<html xmlns=""

<h2>Spring Secured App</h2>
<p>app content ......... at uri <span th:text="${uri}"/></p>
<p>User: <span th:text="${user}"/></p>
<p>Roles: <span th:text="${roles}"/></p>
<form action="/logout" method="post">
    <input type="hidden"
    <input type="submit" value="Logout">

Running example

To try examples, run spring-boot maven plugin (configured in pom.xml of example project below):

mvn spring-boot:run

Or run the main method class from IDE.


Accessing localhost:8080/

Entring username=bob and password=123 and clicking on 'Login' button:

Accessing /h2-console

That's expected because 'bob' does not have 'ADMIN' role. /h2-console access is only allowed for ADMIN per our configuration.

Let's login with username=sara and password=234 who has the ADMIN role.

Accessing /h2-console

Clicking on 'Connect' button and querying USERS table:
