This Spring Boot auto configuration module offers a security filter, capable of
- Decoding an AWS Cognito JWT idToken
- Verifying the JWT token signature
- Verifying the JWT token issuer
- Creating a principal object using the username contained in the JWT token
- Convert the associated cognito groups into SimpleGrantedAuthorities
This modules aim to bridge the gap between Cognito identities and Spring Boot Security Principals.
The module is made available via Maven Central and is currently at version 0.0.6. It can be added to your Maven based project like this :
<dependency>
<groupId>com.ixortalk</groupId>
<artifactId>ixortalk.aws.cognito.jwt.security.filter</artifactId>
<version>0.0.7</version>
</dependency>
or when using Gradle :
compile 'com.ixortalk:ixortalk.aws.cognito.jwt.security.filter:0.0.7'
Create a security configuration, inject the AwsCognitoJwtAuthenticationFilter and add it to the filterchain.
@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter implements Ordered {
private int order = 4;
@Autowired
private AwsCognitoJwtAuthenticationFilter awsCognitoJwtAuthenticationFilter;
@Override
public int getOrder() {
return order;
}
public void setOrder(int order) {
this.order = order;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.headers().cacheControl();
http.csrf().disable()
.authorizeRequests()
.antMatchers("/health").permitAll()
.antMatchers("/v2/**").permitAll()
.antMatchers("/docs/**").permitAll()
.antMatchers("/api/**").authenticated()
.antMatchers("/**").permitAll() // needs to be the last matcher, otherwise all matchers following it would never be reached
.anyRequest().authenticated()
.and()
.addFilterBefore(awsCognitoJwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
}
}
This will add a security filter to your spring boot app that will look for a JWT idToken in the Authorization header of the request.
In order to be able to verify and decode JWT Tokens, the module needs some Cognito configuration. This includes
- userPoolId
- identityPoolId
- region
Add the following configuration to your application to give the verifier sufficient information to decode the JWT token:
com:
ixortalk:
security:
jwt:
aws:
userPoolId: "us-west-2_abcdefghi"
identityPoolId: "us-west-2:xxxxxxxx-aaaa-bbbb-ccc-dddddddddddd"
region: "us-west-2"
To call a secure endpoint with a JWT token, add the authorization header with the Bearer type, followed by the actual token.
curl -v -H "Authorization: Bearer $TOKEN" http://localhost:8080/api/secure | jq
