I am totally new to Spring and started to do the official guides from this site: https://spring.io/guides
I'd like to do this guide: https://spring.io/guides/gs/scheduling-tasks/
I get the following Exception:

The application starter class is this:
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(ScheduledTasks.class, args);
}
}
As you can see, the main method contains a commented line. I've already done a tutorial, namely this one: https://spring.io/guides/gs/consuming-rest/ It's up and running. But I can't run the ScheduledTasks app, which is the following:
@EnableScheduling
public class ScheduledTasks {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
@Scheduled(fixedRate = 5000)
public void reportCurrentTime() {
System.out.println("The time is now " + dateFormat.format(new Date()));
}
}
I use Eclipse and run the Application.java's main as an Application. Could someone please help me?
This question is related to
java
spring
spring-boot
If you package it as a single jar and it's non web app try to load app context as below.
@SpringBootApplication
ApplicationContext ctx = new AnnotationConfigApplicationContext(Main.class);
Or use below plugin to package as a single jar
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
you can specify the external configs by using below command to run
java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
Note that if you are passing the properties as arguments then don't include @PropertySource("classpath:test.properties")
it will override the parameters
In my case we added the @Profile annotation newly in order to ignore the TestApplication class in production mode and the Application class in test mode.
Unfortunately, we forgot to add the following line into the application.properties files:
spring.profiles.active=test
or
spring.profiles.active=production
Without these config no profile was loaded which caused the not-so-much saying Spring Error.
This should be caused by dependency issue, in general, you need to check the dependency.
Try this
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(ScheduledTasks.class, args);
}
}
use this one in your pom.xml :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
or this one :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
Adding the spring boot starter dependency fixed my error.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
This is required if you want to start the tomcat as an embeded server.
I have stuck with same problem. As I didn't define Main.class and the following annotations in Spring-Boot using Maven:
@SpringBootApplication
public class Main {
public static void main(String args[]){
SpringApplication.run(Main.class, args);
}
}
I've had similar problems when the main method is on a different class than that passed to SpringApplcation.run()
So the solution would be to use the line you've commented out:
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
A SpringApplication
will attempt to create the right type of ApplicationContext
on your behalf. By default, an AnnotationConfigApplicationContext
or AnnotationConfigEmbeddedWebApplicationContext
will be used, depending on whether you are developing a web application or not.
The algorithm used to determine a ‘web environment’ is fairly simplistic (based on the presence of a few classes). You can use setWebEnvironment(boolean webEnvironment)
if you need to override the default.
It is also possible to take complete control of the ApplicationContext
type that will be used by calling setApplicationContextClass(…?)
.
[Tip]
It is often desirable to call setWebEnvironment(false)
when using SpringApplication
within a JUnit test.
I had multiple application classes in one Spring Boot project which had the web started included and wanted to avoid it configuring a web environment for one of them so I manually configured it as below:
@SpringBootApplication
public class Application
{
public static void main(String[] args)
{
new SpringApplicationBuilder(Application.class)
.web(false)
.run(args);
}
}
UPDATE for Spring Boot 2 and above:
@SpringBootApplication
public class Application
{
public static void main(String[] args)
{
new SpringApplicationBuilder(Application.class)
.web(WebApplicationType.NONE)
.run(args);
}
}
check your pom.xml is exists
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
I've had a problem like this;For lack this dependency
In my case it happen after excluding the resource folder from the pom
using the following code.
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>*/*.properties</exclude>
</excludes>
</resource>
</resources>
Commenting this code started my code.
Probably you missing @SpringBootApplication in your spring boot starter class.
@SpringBootApplication
public class LoginSecurityAppApplication {
public static void main(String[] args) {
SpringApplication.run(LoginSecurityAppApplication.class, args);
}
}
In my case, spring configurations were not loaded as expected. On running from cmd using below command, it worked:
start java -Xms512m -Xmx1024m <and the usual parameters as needed, like PrintGC etc> -Dspring.config.location=<propertiesfiles> -jar <jar>
The error suggests that the application you are trying to run cannot instantiate an instance of apache tomcat. Make sure you are running the application with tomcat.
if after checking all your dependencies you experience the same problem, try to add the following in your configuration class
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory factory =
new TomcatEmbeddedServletContainerFactory();
return factory;
}
If you are using an external instance of tomcat (especially for intellij), the problem could be that the IDE is trying to start the embedded tomcat. In this case, remove the following from your pom.xml then configure the external tomcat using the 'Edit Configurations' wizard.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
if you experience this exception while using intellij and you are trying to start the application with the run
button. Try starting the application from the command line instead. E.g. ensure that you are in the correct directory (directory with your pom file) assuming this is a springboot
application run mvn spring-boot:run
this did the trick for me.
Additionally I have also seen this error occur when your spring application depends on another application. In this case I had to start the other application first then run.
Add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
I had a similar issue and the problem was a broken maven repo jar file. In my case, the tomcat-embed-core
jar file was broken. So I removed it from the maven repo and refreshed it to download again.
A scan of the @SpringBootApplication
show that it includes the following annotations:
@Configuration
@ComponentScan
@EnableAutoConfiguration
So you could do this too:
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(ScheduledTasks.class, args);
}
}
Problem is exclusion of starter tomcat, I tried exclude it and use vert.x, so when I integrate wit Spring Admin, started problems
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
Adding the annotation @SpringBootApplication
Before the starter class fixed this problem for me (so in essence, this error message can mean "you don't have a @SpringBootApplication
marked class anywhere, you need at least one)
@SpringBootApplication
public class AppStarter {
public static void main(String[] args) {
SpringApplication.run(AppStarter.class, args);
}
}
Clear repository is one possible solution.
Windows -> delete all subfolders in the maven repository:
C:\Users\YourUserName.m2\repository
An other cause of this problem is corruption of maven repository jars so you can use the following command to solve the problem :
mvn dependency:purge-local-repository
If you run it successfully using command line gradle bootRun
, while packaging it with command line gradle jar
to jar file in order to run it with command line java -jar build/libs/demo.jar
, unfortunately, it failed with Exception: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean
, in this case, you need to use task bootRepackage
of gradle plugin spring-boot
to generate special runnable jar.
$ gradle clean bootRepackage
$ java -jar build/libs/demo.jar
I had this Exception in the following situation.
in my POM was properties:
<properties>
<java.version>1.8</java.version>
<!-- The main class to start by executing java -jar -->
<start-class>com.scmaer.java.microservice.Application</start-class>
<cxf.version>3.1.5</cxf.version>
<olingo.version>2.0.10</olingo.version>
<spring.boot.version>1.4.7.RELEASE</spring.boot.version>
<spring.boot.plugin.version>1.5.8.RELEASE</spring.boot.plugin.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<skipTests>false</skipTests>
</properties>
and the name and path of my application class ("start-class") was wrong.
The problem it's in this class:
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
//SpringApplication.run(Application.class, args);
SpringApplication.run(ScheduledTasks.class, args);
}
}
The correct way to launch your application is:
@SpringBootApplication
@EnableScheduling
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
I am using gradle, met seem issue when I have a commandLineRunner consumes kafka topics and a health check endpoint for receiving incoming hooks. I spent 12 hours to figure out, finally found that I used mybatis-spring-boot-starter with spring-boot-starter-web, and they have some conflicts. Latter I directly introduced mybatis-spring, mybatis and spring-jdbc rather than the mybatis-spring-boot-starter, and the program worked well.
hope this helps
