I'm using spring-boot-starter-web to add an embedded webserver to an existing application.
Problem: the servletContext is always null during startup.
I'm running my application using ConfigurableApplicationContext ctx = SpringApplication.run(Config.class);
If I exclude the WebMvcAutoConfiguration the ctx works as follows:
#Configuration
#EnableAutoConfiguration(exclude = {WebMvcAutoConfiguration.class})
public class Config implements ServletContextInitializer {
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.getSessionCookieConfig().setName("yourCookieName");
}
}
But as I need the AutoConfiguration, I remove the exclude. And in this case, the following error is thrown during startup because the servletContext is null.

Solution: I had a statement in application.properties:
spring.main.web_environment=false
Of course the webmvc cannot initialize while this statement exists.

I am trying to consume api using WCF connector instigated with org.tempuri application and consuming soap end point. Recently we have updated our spring dependency to 5.2-release version. Is there any issue with spring version? As before upgrade same piece of code was working.

Any help on this would be much appriciated?
i am using spring boot framework to upload a file, i want to specify the location of a class, then i can upload the file to a dynamic location.
Btw, the strange thing is that this was working in intellij, but after I performed a Clean and Build on the Project, then running, it suddenly stopped working
main application:
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(SmartDustbinServiceApplication.class, args);
}
#Bean
MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setLocation(PathKit.getWebRootPath());
return factory.createMultipartConfig();
}
and the class PathKit have a method like this:
private static String detectWebRootPath() {
try {
String path = PathKit.class.getResource("/").toURI().getPath();
return new File(path).getParentFile().getParentFile().getCanonicalPath();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
then I have got the following exceptions when i starting my springboot project;

I am trying to setup MongoDB repository for CRUD operation in my spring-boot rest app. Here is what i have so far
My applicaiton.yml file
server:
data:
mongodb: localhost
port: 27017
database: dbname
My DbConfiguration class
#Configuration
#EnableMongoRepositories("com.package.path.to.repository")
#Import(value = MongoAutoConfiguration.class)
public class DbConfiguration extends AbstractMongoConfiguration {
private final Logger log = LoggerFactory.getLogger(DbConfiguration.class);
#Autowired
private Mongo mongo;
#Autowired
private MongoProperties mongoProperties;
#Bean
public ValidatingMongoEventListener validatingMongoEventListener() {
return new ValidatingMongoEventListener(validator());
}
#Bean
public LocalValidatorFactoryBean validator() {
return new LocalValidatorFactoryBean();
}
#Override
protected String getDatabaseName() {
return mongoProperties.getDatabase();
}
#Override
public Mongo mongo() throws Exception {
return mongo;
}
}
Then I have my Document class
#Document(collection = "T_BOOK")
public class Book implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String id;
#NotNull
#Size(min = 5, max = 100)
#Field("name")

My Repository Class
package com.package.path.to.repository;
import org.springframework.data.mongodb.repository.MongoRepository;
import java.util.List;
public interface BookRepository extends MongoRepository<Book, String> {
Book findOneById(String id);
List<Book> findAll();
void delete(Book b);
void deleteAll();
}
and finally, the service class
#Service
public class BookService {
#Autowired
private BookRepository bookRepository;
public List<Book> findAll() {
return bookRepository.findAll();
}
public Book findById(String id) {
return bookRepository.findOneById(id);
}
public Book save(Book book) {
return bookRepository.save(book);
}
public void delete(Book book) {
bookRepository.delete(book);
}
public void deleteAll() {
bookRepository.deleteAll();
}
}
When i start the application, I get an error that unable to autowire bookRepository ... here is full exception

As the error implies:
Caused by: java.lang.IllegalArgumentException: Database name must not be empty
at org.springframework.util.Assert.hasText(Assert.java:168) ~[spring-core-4.3.2.RELEASE.jar:4.3.2.RELEASE]
You must set the database name to be used by your application. Or if it is set in here:
My applicaiton.yml file
If not, its a typo error on the filename.
Since you're already using Spring boot, why not use the spring properties for mongodb?
for ver 3.0 driver
spring.data.mongodb.uri=mongodb://user:secret#localhost:12345
for ver 2.x driver
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
More info here http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-nosql.html
This property in application.properties solved for me:
spring.data.mongodb.database=my-database-name
I refactored the Spring doc for creating batch service to implement a stand alone class of my reader
#Component
#PropertySource("classpath:db-config.properties")
public class CsvReader<Item> extends FlatFileItemReader<Item>{
#Autowired
private Environment env;
public CsvReader() {
this.setResource(new ClassPathResource(env.getProperty("csv_file.name")));
this.setLineMapper(new DefaultLineMapper<ImportDataItem>() {
{
setLineTokenizer(new DelimitedLineTokenizer() {
{
setNames(new String[] { "firstName", "lastName" });
}
});
}
});
}
}
NullPointerExceptionis thrown by env.getProperty("csv_file.name") and if it is replaced with a String of filename, it works. I've read another answer & the above code looks good, so could you please help me understand why Environment env isn't autowired?

It all boils down to how objects are constructed and autowired. To construct an object, one must call the constructor. Then you have a reference to the object, and can set its fields. That's what Spring is doing when creating beans and autowiring them: it calls the constructor, and then sets all the fields annotated with #Autowired. It can't set a field before calling the constructor, since it wouldn't have any object yet.
But your constructor tries to access the fields, that are supposed to have been autowired by Spring, before the object was even constructed. That can't possibly happen.
To access an autowired bean from a constructor, constructor injection must be used. Another option would be to move all this code from the constructor to a method annotated with #PostConstruct.
I have a Spring Boot application which I created using jHipster, I am trying to run some integration test cases, and I have configured the test case class using the following annotations:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#WebAppConfiguration
#IntegrationTest
#Transactional
public class ScheduleRepositoryTests {....
But still i get the above mentioned exception. Stack Trace is as follows:

As mentioned here:
https://github.com/jhipster/generator-jhipster/issues/596
this is a bug. And the workaround to make it working is to add '#ActiveProfiles("dev")' as a class level annotation on the test case class:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#WebAppConfiguration
#IntegrationTest
#ActiveProfiles("dev")
#Transactional
public class ScheduleRepositoryTests {...
Here, the "dev" parameter signals towards the 'application-dev.yml' file used for the tests configuration, depending on the type of environment you have configured.
