@AlainJanssens can you paste here some sample code on how you use @Valid (both init and runtime) so that I can include it in a unit test?

Turns out this is not caused by #15. I have looked into this and managed to get the @Valid annotation working. I've added a unit test for this in the new branch

Few things to do:

declare your config as an AnnotationConfigWebApplicationContext:

@Configuration
@ComponentScan("com.amazonaws.serverless.proxy.spring.echoapp")
public class EchoSpringAppConfig {

    @Autowired
    private AnnotationConfigWebApplicationContext applicationContext;

    @Bean
    public SpringLambdaContainerHandler springLambdaContainerHandler() throws ContainerInitializationException {
        SpringLambdaContainerHandler handler = SpringLambdaContainerHandler.getAwsProxyHandler(applicationContext);
        handler.setRefreshContext(false);
        return handler;
    }

    @Bean
    public ObjectMapper objectMapper() {
        return new ObjectMapper();
    }

    @Bean
    public MockLambdaContext lambdaContext() {
        return new MockLambdaContext();
    }

    @Bean
    public javax.validation.Validator localValidatorFactoryBean() {
        return new LocalValidatorFactoryBean();
    }
}

Add the required dependencies in the pom.xml file:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>5.4.1.Final</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>javax.el</groupId>
  <artifactId>javax.el-api</artifactId>
  <version>2.2.4</version>
</dependency>
<dependency>
  <groupId>org.glassfish.web</groupId>
  <artifactId>javax.el</artifactId>
  <version>2.2.4</version>
</dependency>

Use the @Valid annotation in your method.

@RequestMapping(path = "/user", method=RequestMethod.POST, consumes = MediaType.APPLICATION_JSON)
    public ResponseEntity<ValidatedUserModel> createUser(@Valid @RequestBody ValidatedUserModel newUser, BindingResult results) {
...
