I'm building an application that connects to a Stardog database via the Snarl API alongside Springboot for the front end. The autowired beans for the snarlTemplate are working fine, but any Components I defined are having issues. I've taken out the autowiring for the ValidationDAO and gotten it to load. I've looked at the other posts with this same problem, but I couldn't get a solution.
First off, here's the DAO (which I have annotated as a component)... Validation is a POJO defined in a different file.
src/main/java/validation/ValidationDAO.java
#ComponentScan("com.complexible.stardog.ext.spring")
#Component
public class ValidationDAO {
private static final Logger logger = LoggerFactory.getLogger(ValidationDAO.class);
#Autowired
public SnarlTemplate snarlTemplate;
public List<Validation> validate() {
// TODO: file input
String query = "SELECT * WHERE { ?s ?p ?o }";
logger.debug("DAO Query: " + query);
List<Validation> results = snarlTemplate.query(query, new RowMapper<Validation>() {
public Validation mapRow(BindingSet bindingSet) {
Validation v = new Validation();
// set results of query
v.setSubject(bindingSet.getValue("s").stringValue());
v.setPredicate(bindingSet.getValue("p").stringValue());
v.setObject(bindingSet.getValue("o").stringValue());
// set error message
v.setError("No given description.");
return v;
}
});
return results;
}
public SnarlTemplate getSnarlTemplate() {
return snarlTemplate;
}
public void setSnarlTemplate(SnarlTemplate snarlTemplate) {
this.snarlTemplate = snarlTemplate;
}
}
And then here's the HomeController:
src/main/java/validation/HomeController.java
#RestController
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
#Autowired
public ValidationDAO validationDAO;
#RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
List<Validation> results = validationDAO.validate();
logger.debug("Found " + results.size() + " errors in ontology.");
model.addAttribute("results", results);
return "home";
}
public ValidationDAO getValidationDAO() {
return validationDAO;
}
public void setValidationDAO(ValidationDAO validationDAO) {
this.validationDAO = validationDAO;
}
}
Root context:
src/main/webapp/WEB-INF/spring/root-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Finally, the full error message.

The ComponentScan-annotation should be in a configuration and not in the component class. I really don't know if it works at all and it contains a package you don't mention.
Second point: Don't use field injection. (http://olivergierke.de/2013/11/why-field-injection-is-evil/)
Now back to the problem: I think your component scan in the xml file is wrong or your packages have some confusing names. But I am pretty sure this is your maven/gradle file path ;) It should not contain the file path but only the package validation.
<context:component-scan base-package="validation"/><context:annotation-config/>
You are sure your xml configuration is loaded?

I have annotated my Implementation class as #Service
#Service
public class MainServiceImpl implements someDAOClass{
#Autowired
private someDAOClass someDAOClass1;
#Transactional
public list<someDAOClass> getSomeDAOClass(){
//return statement here
}
}
Additionally, my DAO class is annotated as #Repository, non-transactional. Yesterday I achieved the desired result with just using a DAO but now I made changes I am not sure why it is not all working together.
I have tried using #ComponentScan on my controller, just in case but that was futile.
As I am using STS(Eclipse), it appears I cannot create a root package and keep controller there as suggested as a solution in another SO post. Therefore, I am looking for other solutions apart from changing architecture in system explorer.
Your service implementation class should implements Service and not DAO
#Service
public class MainServiceImpl implements MainService {
You should define your bean for example:
#Bean
public MainService mainService(){
return new MainServiceImpl ();
}
The error says,
No qualifying bean of type 'domain.service.MainService' available
MainServiceImpl is a someDAOClass, not a MainService. So you should implement MainService.
I'm trying to get a multi-tenant mongodb app running, where each tenant has it's own database. I've coded an alternate to SimpleMongoDbFactory but whatever I try to do as far as java config goes the embedded mongo database doesn't start up any more.
What I'd like to know is how to configure just the replacement MongoDbFactory and keep the rest of the spring boot autoconfig? or if I need to replace all of the config to do it?
I even tried copying MongoDataAutoConfiguration code into my own config class and that still stopped the embedded mongo db from starting up.
Edited... to make the question more concrete.
I was expecting to be able to do something like this, (although I would use my own MongoDbFactory class) and still have the auto-configured embedded database start when the application starts. Latest version of spring boot (1.3.5) and dependencies.
package com.mmt;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;

import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;

#Autowired
private MongoClient mongo;
#Bean
public SimpleMongoDbFactory mongoDbFactory(MongoClient mongo) throws Exception {
String database = this.properties.getMongoClientDatabase();
return new SimpleMongoDbFactory(mongo, database);
}
}
But I get this stacktrace instead.

I have created a sample Spring Boot application that runs perfectly fine when service classes are all in one package , but if a Service class refers to another service class in a different package then I get the BeanCreationException
The Code for the Application is given below
Main.java
#SpringBootApplication
public class Main {
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
}
MyRunner
#Component
#ComponentScan(basePackages ="com.springboot.helloworld")
public class MyRunner implements CommandLineRunner {
#Autowired
private GreeterService greeterService;
#Override
public void run(String... args) throws Exception {
System.out.println(greeterService.greetGuest("John Doe"));
}
}
GreeterService and GreeterServiceImpl are in com.springboot.helloworld.Greeter
#Service
public class GreeterServiceImpl implements GreeterService {
#Autowired
Sample service;
#Override
public String greetGuest(String greeter) {
if (greeter == null) {
return "Looged in as Guest";
}
return "Hello " + greeter + " How are you?";
}
}
Sample and SampleImpl are in different Package com.springboot.helloworld.Sampler
Error Recieved is

You have to use the #Component annotation something like below:
#ComponentScan({"com.springboot.helloworld","service"})
Your application is clearly expecting a command line argument and you're not supplying any.
I had this issue after switching to spring 5. The problem was that an annotation processor was being run at build time to generate some helper classes, a side effect of this was that a file, spring.properties was generated. This got deployed to META-INF. When spring 5 scans for components, it checks to see if this file exists (as a resource loaded by the class loader), if it exists then it only considers the classes listed in the file when looking for components. In my case the annotation processor that generated the file wasn't looking for components, so the component classes weren't in the file. The fix was to delete the file. Without the file, then the component scanning works as expected.
I'm trying to run simple mailsender service:
#Service
public class MailService {
#Autowired
private MailSender mailSender;
#Autowired
private SimpleMailMessage templateMessage;
#Autowired
private AuthenticationService authenticationService;
public void sendMessage(SaveSurveyDTO saveSurvey) {
title += "title2";
templateMessage.setSubject(title);
// templateMessage.setTo(email.toString());
templateMessage.setTo("my#mail.com");
mailSender.send(templateMessage);
}
}
#Configuration
public class MailConfig {
#Bean
public JavaMailSenderImpl mailSender() {
JavaMailSenderImpl sender = new JavaMailSenderImpl();
Properties props = new Properties();
props.put("mail.smtp.auth", true);
props.put("mail.debug", "true");
props.put("mail.smtp.host", "adres");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.auth.mechanisms", "NTLM");
props.put("mail.smtp.auth.ntlm.domain", "DOMAIN");
sender.setHost("host");
sender.setPort(25);
sender.setJavaMailProperties(props);
sender.setUsername("username");
sender.setPassword("pass");
return sender;
}
}
When I'm trying to run this, I recieve the following error:

The error is telling you what is wrong:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.mail.SimpleMailMessage] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
The main issue is the fact you are having field in your service of the type SimpleMailMessage which you have annotated with #Autowired. However there is no such bean in your #Configuration class.
Either add that bean definition to your configuration (which I wouldn't recommend) or simply create the SimpleMailMessage inside your method.
public void sendMessage(SaveSurveyDTO saveSurvey) {
SimpleMailMessage message = new SimpleMailMessage();
title += "title2";
message.setSubject(title);
// templateMessage.setTo(email.toString());
message.setTo("my#mail.com");
mailSender.send(message);
}
Pro Tip
You are using Spring Boot then use it... Remove your#Configuration class and just put the configuration in application.properties. Spring Boot already has mail support (as of Spring Boot 1.2 that is!).
spring.mail.host=adres
spring.mail.port=25
spring.mail.username=username
spring.mail.password=password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.auth.mechanisms=NTLM
spring.mail.properties.mail.smtp.auth.ntlm.domain=DOMAIN
spring.mail.properties.mail.debug=true
The problem you are getting is that Spring cannot inject an instance of SimpleMailMessage:
#Autowired
private SimpleMailMessage templateMessage;
This is completely normal and you should not construct a SimpleMailMessage this way, it is not a Spring Bean. Rather, use the default constructor:
SimpleMailMessage templateMessage = new SimpleMailMessage();
and set the properties from, to, etc. according to your needs.
Please add the Qualifier like this
#Autowired
#Qualifier("mailSender")
private MailSender mailSender;
