IllegalStateException: No function defined for Spring Cloud Function

I have defined a function in my Spring Cloud Function project, but after executing function (ScanQrCode) as AS Lambda I get:

The weired thing here is that I have commented out the consume, supplier and function functions...I don´t know why Spring or AWS Lambda considered them...
Here are my classes:
Spring Boot App
#SpringBootApplication
public class FoodhatQrApplication {
public static void main(String[] args) {
SpringApplication.run(FoodhatQrApplication.class, args);
}
// #Bean
// public Function<String, String> function(){
// return input -> input;
// }
//
// #Bean
// public Consumer<String> consume(){
// return input -> System.out.println("Input: " + input);
// }
//
// #Bean
// public Supplier<String> supply(){
// return () -> "Hello World";
// }
}
Function class
#Component
public class ScanQrCode implements Function<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent>{
#Autowired
private QrCodeRepository qrCodeRepository;
#Override
public APIGatewayProxyResponseEvent apply(APIGatewayProxyRequestEvent request) {
APIGatewayProxyResponseEvent response = new APIGatewayProxyResponseEvent();
response.setStatusCode(302);
response.setHeaders(Collections.singletonMap("location" , "http://www.google.de"));
return response;
}
}
What am I missing?

Function Component Scan Adding spring.cloud.function.scan.packages might help.
Reference: https://cloud.spring.io/spring-cloud-function/reference/html/spring-cloud-function.html#_function_component_scan

You definitely need to add your function name in our case it "ScanQrCode" to AWS lambda env variables.
FUNCTION_NAME: ScanQrCode

Spring unit test MockMvc fails when using custom filter in Spring Security

I have a web application that should only be callable from specific IP addresses. Other than that, there is no need for authentication or for authorization; if you're coming from the right IP, you can see everything.
To that end, searching StackOverflow and other places, I found a number of suggestions for filtering requests by IP address in Spring Security. They all took this form (extending WebSecurityConfigurerAdapter using java configuration):
http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')");
However, that never worked for me; it never rejected any request, no matter what IP address I made the request from. Instead, I implemented my IP filtering with a custom filter like this:
#Configuration
#EnableWebSecurity
#PropertySource("classpath:config.properties")
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(SecurityConfig.class);
#Autowired
private Environment env;
#Override
protected void configure(HttpSecurity http) throws Exception {
String ipRange = env.getRequiredProperty("trusted_ips");
logger.info("##### SETTING UP SECURITY CONFIGURATION #############");
logger.info("## trusted_ips: " + ipRange);
logger.info("##### SETTING UP SECURITY CONFIGURATION - END #############");
http.addFilterBefore(new IPSecurityFilter(ipRange), J2eePreAuthenticatedProcessingFilter.class)
.authorizeRequests().antMatchers("/**").permitAll();
}
}
My IPSecurityFilter:
public class IPSecurityFilter extends OncePerRequestFilter {
private static final Logger logger = LoggerFactory.getLogger(IPSecurityFilter.class);
private String[] ipAddresses;
public IPSecurityFilter(String strIPAddresses) {
logger.info("#### Our IP Address whitelist: " + strIPAddresses);
this.ipAddresses = strIPAddresses.split(",");
}
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
logger.info("Checking whether request should be allowed: " + request.getRequestURI());
logger.info("### Request is coming from IP address: " + request.getRemoteAddr());
for (String ipAddress : ipAddresses) {
if (ipAddress.equals(request.getRemoteAddr())) {
logger.info("### Allowing request from ip address: " + request.getRemoteAddr());
return; // We accept requests from this IP address
}
}
// The remote IP address isn't on our white list; throw an exception
throw new AccessDeniedException("Access has been denied for your IP address: " + request.getRemoteAddr());
}
}
This seems to work in that the request is rejected if it originates from an IP Address that isn't on my white list.
However, with this configuration, my unit (using MockMvc) test fails; and it fails in a way that I would never have expected. When the unit test runs, it appears to use the Spring Security configuration correctly and the request passes the security test (the IP white list includes 127.0.0.1 and according to the log that is generated while the test is being run, the request is coming from that IP). However, the request never seems to be routed to my controller.
Here is my test:
#RunWith(SpringRunner.class)
#WebMvcTest()
//#WebMvcTest(value = HandlerController.class)
#AutoConfigureMockMvc
#Import(SecurityConfig.class)
public class HandlerControllerTest {
#Autowired
private MockMvc mvc;
#Test
public void getIndex() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
}
And finally, here is my controller (please ignore the idiotic way that I'm generating the JSON return value, it's still very early in development):
#RestController
public class HandlerController {
private static final Logger logger = LoggerFactory.getLogger(HandlerController.class);
#RequestMapping("/")
public String index() {
logger.info("### handling a request for / ###");
return "{\"services\":[\"OutboundMessageService\"]}";
}
}
And here are the test results:

As can be seen in the log messages, the IP filter is being invoked and is allowing the request to continue. However, the debug string that is being emitted in my handler is nowhere to be seen and the return body is blank. Can anyone tell me why my security filter would prevent MockMvc from having its request successfully routed to my controller?
Final Note: if I use the http.authorizeRequests().anyRequest().access("hasIpAddress('127.0.0.1/0')"); configuration that I first listed or completely get rid of Spring Security by removing my SecurityConfig class, the request is routed successfully to my handler.

I figured out how to make the test work. I was not able to find a single article that answered my question but by taking different suggestions from multiple blog posts, I came up with this which works for me:
#RunWith(SpringRunner.class)
#WebMvcTest(controllers = HandlerController.class)
public class HandlerControllerTest {
private MockMvc mvc;
#Autowired
private WebApplicationContext webApplicationContext;
#Before
public void setUp() {
// mvc = MockMvcBuilders.standaloneSetup(new HandlerController()).build();
mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}
#Test
public void getIndex() throws Exception {
mvc.perform(get("/").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"services\":[\"OutboundMessageService\"]}", true));
}
#Test
public void getMessageService() throws Exception {
mvc.perform(get("/OutboundMessageService").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().json("{\"status\": \"SUCCESS\"}", true));
}
}
As you can see, I am no longer auto-wiring the MockMvc object and allowing it be automatically set up but am instead setting it up myself in the setUp() method. The commented-out line in the setUp() method works to successfully test my controller also but it doesn't route the request through my Spring Security IP address filter. I'm leaving it in so that users that don't need to test Spring Security can see an alternate method to set up the MockMvc object. The uncommented line sets up a MockMvc object such that it runs the request through both the security filters and my controller.

I know it is late but for others looking for the answer, you can add that filter to the MockMvc object like this:
#Autowired
private MockMvc mvc;
#Autowired
private YourCustomFilter filter;
#Before
public void setUp() {
mvc = MockMvcBuilders.webAppContextSetup(webApplicationContext)
.addFilter(filter).build();
}

Migrating from Migrate to Spring MVC 4 + Hibernate5

I'm migrating an application from Jersey 1.18, Spring 3, Hibernate 3.6, Maven to a completely new architecture: Spring 4.3 (via Spring Boot), Hibernate 5 and Gradle.

Update
Here it is a piece of gradle build:
compile('org.springframework.boot:spring-boot-starter-data-jpa')
// ...
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
compile group: 'org.hibernate' , name: 'hibernate-core' , version: '5.2.8.Final'
// ...
What I'm missing?
Thanks, Davide.

Based on the spring boot error message, it fails to build the DefaultJpaContext bean whose constructor requires Set<javax.persistence.EntityManager> entityManagers.
Looks like you have Spring-Data dependency in your pom.xml(or build.gradle) which requires the jpa EntityManagerFactory while you have Hibernate(LocalSessionFactoryBean) stuff. Do you have to have DefaultJpaContext bean?
