4.8.2.7. Creating Custom OAuth2 Protected Controllers

If you need to create a custom REST controller protected with the OAuth2 authentication then you have to do the following:

  1. Suppose you have the following REST controller:

    package com.company.test.portal.myapi;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.company.test.services.SomeService;

@RestController
@RequestMapping("/myapi")
public class MyController {

    @Inject
    protected SomeService someService;

    @GetMapping("/dosmth")
    public String doSmth() {
        return someService.getResult();
    }
}

  2. Create a new Spring configuration file with name rest-dispatcher-spring.xml under the root package (com.company.test) of web or portal module. The content of the file must be as follows:

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:security="http://www.springframework.org/schema/security"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.1.xsd">

    <!-- Define a base package for your controllers-->
    <context:component-scan base-package="com.company.test.portal.myapi"/>

    <security:http pattern="/rest/myapi/**"
                   create-session="stateless"
                   entry-point-ref="oauthAuthenticationEntryPoint"
                   xmlns="http://www.springframework.org/schema/security">
        <!-- Specify one or more protected URL patterns-->
        <intercept-url pattern="/rest/myapi/**" access="isAuthenticated()"/>
        <anonymous enabled="false"/>
        <csrf disabled="true"/>
        <cors configuration-source-ref="cuba_RestCorsSource"/>
        <custom-filter ref="resourceFilter" before="PRE_AUTH_FILTER"/>
        <custom-filter ref="cuba_AnonymousAuthenticationFilter" after="PRE_AUTH_FILTER"/>
    </security:http>
</beans>

  3. Define an additive application property cuba.restSpringContextConfig in the properties file of the module,.e.g. portal-app.properties:

    cuba.restSpringContextConfig = +com/company/test/rest-dispatcher-spring.xml

  4. The new controller runs in the context of the CubaRestApiServlet. So the URL for controller methods will start with the /rest, i.e. the doSmth() method will be accesed by the URL: http://localhost:8080/app-portal/rest/myapi/dosmth.

    Warning

    URL of the custom controller MUST NOT start with the /rest/v2.
