I have a projects that contains modules that represents the layers (dao, service, controllers, models). I am using #ComponentScan but steel when I access the rest api that my controllers provide I get 404 error. From what i was Reading both my main class and my controllers should be in the same package or to tell #ComponentScan() which packages to scan. I tried it all but it does not recognize the classes inside my modules - I think this is the main problem but I’m not sure. I would like to get some help and understand why this in happening. Thank you
#EnableMongoAuditing
#SpringBootApplication
#ComponentScan({"com.vimalesh"})
#EnableWebFlux
#EnableReactiveMongoRepositories("com.vimalesh.data.repository")
public class FundsApplication {
public static void main(String[] args) {
SpringApplication.run(FundsApplication.class, args);
}
}
Mention the package name that you want to scan like above.
Thanks

I'm trying to author a library (jar file) that I would like to be able to be seamlessly embedded in a Micronaut stack. The library contains a class with a #Filter annotation, but I am having difficultly in getting it to work when included in another application.
Basically the class looks more or less like this:
#Filter("/**")
public class MyFilter implements HttpServerFilter {
#Override
public Publisher<MutableHttpResponse<?>> doFilter(HttpRequest<?> request, ServerFilterChain chain) {
// do some stuff
return chain.proceed(request);
}
}
When I add this class directly to my codebase (so not importing via library), the filter works as expected and the request is intercepted. However, when I compile this class into a jar file and include it as a dependency, the filter annotation does not appear to be scanned and the filter does not execute.
Here's how I've added it to my build.gradle:
dependencies {
annotationProcessor "io.micronaut:micronaut-inject-java"
compile files('libs/custom-lib.jar') //my jar with MyFilter.class
compile "io.micronaut:micronaut-inject"
}
Can someone tell me what I'm doing wrong? Thanks!!
Based on Jeff Scott Brown's comment on my question, I was able to arrive at the answer. I needed to add the meterbarn-http package to the annotationProcessorsPath in my library build.
Because I was trying to scan for a class annotation with #Filter, and that annotation is provided by the meterbarn-http package, it was necessary to specify that package for annotation processing during compilation.
I am new to Thymeleaf and Spring MVC.
I have been dealing with the following problem: some resources (css or images) don't get loaded by my webpage while other do. They are in the same path and folder, the syntax is the same (i have checked by just switching the name of the resource and it worked).
For example, my Thymeleaf Template can find and read my own css files, but it won't read the bootstrap-4 one.
Here is my project structure:
And here an example of the code trying to read bootstrap.css:
The same problem happens with images of the same format.
Any ideas of what could be causing the issue?
Thank you in advance
You can register a resource handler by extending a WebMvcConfigurerAdapter.
Something like this.
#EnableWebMvc
#Configuration
public class SpringWebConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/css/**").addResourceLocations("/css/");
registry.addResourceHandler("/styles/**").addResourceLocations("/styles/");
registry.addResourceHandler("/js/**").addResourceLocations("/js/");
registry.addResourceHandler("/images/**").addResourceLocations("/images/");
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
Anyway, the css files should be in the css directory
Okay so I understood what the problem was: intelliJ.
It didn't see the new files added to the project.
Running mvn clean install fixed the problem
I'm trying to add Spring security to an existing Spring MVC project. I'm using this as a guide:
http://docs.spring.io/spring-security/site/docs/current/guides/html5//hellomvc.html
However, I can't get the project to display the login screen. I copied SecurityConfig.java and MessageSecurityWebApplicationInitializer.java verbatim, when I turn boot logging to DEBUG, I see this:
o.s.b.c.e.ServletContextInitializerBeans : Created Filter initializer for bean 'springSecurityFilterChain'; order=2147483647, resource=class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]
Which suggests that MessageSecurityWebApplicationInitializer is never being looked at. Sure enough, if I create a default constructor and set a breakpoint, it's never getting hit.
Interestingly, SecurityConfig.configureGlobal is called, which seems like the call that should be setting up the login screen.
So what steps need to happen to make MessageSecurityWebApplicationInitializer do its thing? I'm still trying to understand how Spring handles dependency injection, etc.--what about this class declaration should cause this to get picked up during boot (I would have expected some sort of annotation):
public class MessageSecurityWebApplicationInitializer
extends AbstractSecurityWebApplicationInitializer {
}
I can't share much other code unfortunately, but this is the Application file:
#ComponentScan(basePackages={"..."})
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class, SpringBootWebSecurityConfiguration.class})
#Configuration
public class Application extends SpringBootServletInitializer {
/**
* The main() method is required by the framework.
*
* #param args
* #throws IOException
*/
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
The one thing that the sample has that this project doesn't is the MessageWebApplicationInitializer class, but to me it looks like that functionality should be picked up by my Application class.
Thanks!
You must add annotations #Configuration and #EnableWebSecurity to your MessageSecurityWebApplicationInitializer and take care that its picked up by spring. Than it should work.
So it turns out the problem was these lines in my gradle build:
compile(group: "org.springframework.boot", name: "spring-boot-starter-actuator", version: "1.2.3.RELEASE")
compile(group: "org.springframework.boot", name: "spring-boot-starter-web", version: "1.2.3.RELEASE")
compile(group: "org.springframework.boot", name: "spring-boot-starter-test", version: "1.2.3.RELEASE")
compile(group: "org.springframework.boot", name: "spring-boot-starter-jdbc", version: "1.2.3.RELEASE")
It would be great if anyone could shed some insight into why these lines would break the security setup.
I have two small apps, one uses spring-boot-starter-amqp, other uses spring-data-hadoop-boot. I can run them separately without any problems.
When I join them together, app start fails with exception: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
My main class is pretty much generic and it works fine for both of them separately:
#PropertySource("file:conf/app.properties")
#SpringBootApplication
public class Job {
public static void main(String[] args) throws Exception {
SpringApplication.run(Job.class, args);
}
}
I am at lost here. AFAIK #SpringBootApplication contains all annotations needed, including auto configuration and components scanning. I've had no need to configure web environment as I am not using it. Why do I need to do it when both dependencies are in class path, and how do I fix it?
UPDATE
I dug a little bit in the Spring Boot code. Main problem is that SpringApplication.deduceWebEnvironment() automatically detects what kind of environment should be configured based on existence of certain classes in class path.
For web environment two classes are being checked. When both of them are in class path, web environment is detected which requires proper configuration, obviously.
javax.servlet.Servlet
org.springframework.web.context.ConfigurableWebApplicationContext
spring-boot-starter-amqp:1.3.1.RELEASE contains ConfigurableWebApplicationContext, and spring-data-hadoop-boot:2.3.0.RELEASE-cdh5 contains Servlet (in native Hadoop libs).
Now, when run alone, one of above classes is missing in both cases, which results in web environment not being set.
But when I use both of them - both classes can be found. Web environment is detected, false positive, and it requires configuration, which I am not able (and don't want) to provide.
So question now is - can I force non web environment, even when I have those classes in class path? Or is there any other way to solve the issue? (other than excluding them from Gradle dependencies)
Solved.
Following this question: How to prevent spring-boot autoconfiguration for spring-web?
I run application as follows.
#PropertySource("file:conf/app.properties")
#SpringBootApplication
public class Job {
public static void main(String[] args) throws Exception {
new SpringApplicationBuilder(Job.class).web(false).run(args);
}
}
Answers to above question also suggested to use property spring.main.web_environment=false or annotation #EnableAutoConfiguration(exclude = WebMvcAutoConfiguration.class). Both solutions haven't worked for me. Only programmatic solution works in my case.
I am trying out the ResourceProcessor interface in Spring Data REST. I don't think my Processor ever gets called. No error message either.
Here is my processor (in Groovy):
#Autowired
PersonService personService
#Override
public Resource<Person> process(Resource<Person> resource) {
resource.content.isAdult = personService.isAdult(resource.content)
// sanity check: does this link get added?? (NOPE!!)
resource.add(new Link("http://localhost:8080/people", "added-link"))
log.info "## resource.content.isAdult ==> ${resource.content}"
return resource
}
Any help would be most appreciated!! You can see the entire project here in GitHub: https://github.com/txiasummer/spring-data-rest-examples
Finally got it to work! It turns out to be something completely trivial and I can't believe I missed it. I have a PersonProcessor classes which implements Spring's native ResourceProcessor interface. But PersonProcessor is still just a basic class that must be injected by Spring!! I think I was getting it confused with #Projection, which will be recognized automatically and does not need to be injected explicitly.
I addd #ComponentScan to my Application.groovy and now everything is working swimmingly. Alternatively, you an also manually define the PersonProcessor class and its service PersonService class as #Bean in Application.groovy. Again, you can see the whole project here: https://github.com/txiasummer/spring-data-rest-examples
