I want to write a test to mock it, but not able to do it. Its throwing following exception.
Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/objenesis/SpringObjenesis
My test configuration:
#Bean(name = "producerExt")
FactoryBean sampleApplication() {
return new AbstractFactoryBean() {
#Override
public Class getObjectType() {
return SampleApplication.class;
}
#Override
protected SampleApplication createInstance() {
return mock(SampleApplication.class);
}
};
}
#Bean(name = "audit-task-executor")
public ThreadPoolTaskExecutor threadPoolTaskExecutor() {
return mock(ThreadPoolTaskExecutor.class);
}
Implemented FactoryBean to avoid invocation of #PostConstruct

I run my spring boot application with
mvn spring-boot:run -Dspring-boot.run.arguments="test1, test2, test3"
I need this 3 arguments in my runnable. How can i access them in my Compressor runnable class? It prints null.
#Configuration
public class MultiThreadConfig {
#Bean
public TaskExecutor taskExecutor() {
return new SimpleAsyncTaskExecutor(); // Or use another one of your liking
}
#Bean
public CommandLineRunner schedulingRunner(TaskExecutor executor) {
return new CommandLineRunner() {
public void run(String[] args) throws Exception {
executor.execute(new Compressor(args));
}
};
}
}
public class Compressor implements Runnable {
#Autowired
ApplicationArguments appArgs;
String[] args;
// Constructor
public Compressor(String[] args) {
//Initialization of atributes
}
#Override
public void run() {
System.out.println("COMPRESSOR YO");
System.out.println(Arrays.toString(args));
System.out.println(appArgs);
}
}
As Jesper pointed out you are creating the Compressor object by yourself using new keyword so the ApplicationArguments will not be autowired as this instance of Compressor is not managed by Spring. The solution is to create a bean for Compressor object and let it be managed by Spring. For example :
#Configuration
public class MultiThreadConfig {
#Bean
public TaskExecutor taskExecutor() {
return new SimpleAsyncTaskExecutor(); // Or use another one of your liking
}
#Bean
public Compressor compressor(ApplicationArguments applicationArguments) {
return Compressor(applicationArguments);
}
#Bean
public CommandLineRunner schedulingRunner(TaskExecutor executor, Compressor compressor) {
return new CommandLineRunner() {
public void run(String[] args) throws Exception {
executor.execute(compressor);
}
};
}
}
and
public class Compressor implements Runnable {
private final ApplicationArguments appArgs;
private final String[] args;
#Autowired
public Compressor(ApplicationArguments applicationArguments) {
appArgs = applicationArguments;
args = applicationArguments.getSourceArgs();
}
#Override
public void run() {
System.out.println("COMPRESSOR YO");
System.out.println(Arrays.toString(args));
}
}
Note here that I am using constructor injection instead of field injections which is typically better option.
If you do not want to crate a bean in configuration you could also mark Compressor with Spring stereotype :
#Component
public class Compressor implements Runnable {
private final ApplicationArguments appArgs;
private final String[] args;
public Compressor(ApplicationArguments applicationArguments) {
appArgs = applicationArguments;
args = applicationArguments.getSourceArgs();
}
//...
}
and use instance of it in your configuration like shown above :
#Bean
public CommandLineRunner schedulingRunner(TaskExecutor executor, Compressor compressor) {
//...
}
I am new to spring, I have following boot application classes. I am trying to connect to AWS SQS from Spring boot application. The code is as below:

When Maven builds, I get the following error:

I'm not sure but it seems your awsProperties.getAccessKey() returns null.
I'm trying to Autowire service inside java class which is extended from TimerTask. This Returning null value while trying to return service in java class. This is the class in which I'm trying to Autowire service:
#Component

#Autowired
FileDetailsService fileDetailsService;
int count = 1;
#Override
public void run()
{
fileDetailsService.updateProcessingStatus(fileAudit);
}
Configuration classes: There is no web.xml.....I have configured in java using spring 4
//DataConfig.java
#Configuration
#MapperScan("com.fileC.mapper")
public class DataConfig {
#Bean
public DataSource dataSource() {
SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
dataSource.setDriverClass(oracle.jdbc.driver.OracleDriver.class);

return dataSource;

CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
commonsMultipartResolver.setDefaultEncoding("utf-8");
commonsMultipartResolver.setMaxUploadSize(50000000);
return commonsMultipartResolver;
}
}
I'm using Spring4, java1.8, ibatis, SQL database.
Here is the service class,
#Service("fileDetailsService")
#Transactional
public class FileDetailsServiceImpl implements FileDetailsService{
private static Logger logger = LoggerFactory.getLogger(FileDetailsServiceImpl.class);
#Autowired
FileDetailsMapper fileDetailsMapper;
#Override
public void insertFileInfo(Details details){
fileDetailsMapper.insertDetails(details);
}
Here is the exception details,
fileAuditMapper>>>>null

Also I added -javaagent:D:/libs/spring-instrument-4.1.7.RELEASE.jar to VM options for this test.
But it always fails. What did I miss?
Please check this link, i think it is the similar problem u are facing.
How to configure AspectJ with Load Time Weaving without Interface
In this link he has asked to provide both aspectjweaver.jar and spring-instrument.jar in vm argument.
Good to know it worked. :)
I want to setup an object pool in my spring application with annotation only.
I started out with this example taken from Spring docs: http://docs.spring.io/spring/docs/2.5.x/reference/aop-api.html#aop-ts-pool.
Here is how I translate the XML configuration:
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class SpringObjectPoolTest {
public static void main(String[] args) throws Exception {
context = new SpringApplicationBuilder(SpringObjectPoolTest.class) //
.addCommandLineProperties(false) //
.web(false) //
.headless(false) //
.registerShutdownHook(true) //
.application() //
.run();
context.getBean(SpringObjectPoolTest.class).go();
}
#Resource(name = "pfb")
private FactoryBean<MyTask> pool;
#Resource(name="pool")
private TargetSource targetSource;
private static ConfigurableApplicationContext context;
#Bean(name = "task")
#Scope("prototype")
public MyTask createNewTask() {
return new MyTask();
}
#Bean(name = "pool")
public CommonsPoolTargetSource setupObjectPool() {
CommonsPoolTargetSource pc = new CommonsPoolTargetSource();
pc.setMaxSize(25);
pc.setTargetBeanName("task");
return pc;
}
#Bean(name = "pfb")
public ProxyFactoryBean createProxyFactoryBean() {
ProxyFactoryBean pfb = new ProxyFactoryBean();
pfb.setTargetSource(targetSource);
return pfb;
}
private void go() {
try {
pool.getObject().speak();
} catch (Exception e) {
e.printStackTrace();
}
}
}
However I get this exception:
org.springframework.beans.factory.BeanCurrentlyInCreationException:
Error creating bean with name 'pfb':
org.springframework.beans.factory.FactoryBeanNotInitializedException:
Cannot determine target class for proxy
You are a bit over engineering this. Spring already knows how to inject a proxied MyTask, there is no need to have a FactoryBean<MyTask> or to call getObject() on the pool. In "pooledTask" below Spring knows that by injecting a ProxyFactoryBean ("pfb") it will actually inject the instance that factory bean creates, not the factory bean itself. Here's how I'd do it:
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class SpringObjectPoolTest {
public static void main(String[] args) throws Exception {
context = new SpringApplicationBuilder(SpringObjectPoolTest.class) //
.addCommandLineProperties(false) //
.web(false) //
.headless(false) //
.registerShutdownHook(true) //
.application() //
.run();
context.getBean(SpringObjectPoolTest.class).go();
}
private static ConfigurableApplicationContext context;
#Resource(name = "pfb")
private MyTask pooledTask;
#Resource(name="pool")
private CommonsPoolTargetSource targetSource;
#Bean(name = "task")
#Scope("prototype")
public MyTask createNewTask() {
return new MyTask();
}
#Bean(name = "pool")
public CommonsPoolTargetSource setupObjectPool() {
CommonsPoolTargetSource pc = new CommonsPoolTargetSource();
pc.setMaxSize(25);
pc.setTargetBeanName("task");
return pc;
}
#Bean(name = "pfb")
public ProxyFactoryBean createProxyFactoryBean() {
ProxyFactoryBean pfb = new ProxyFactoryBean();
pfb.setTargetSource(setupObjectPool());
return pfb;
}
private void go() {
try {
pooledTask.speak();
// getting another object from pool
MyTask someOtherTask = (MyTask) targetSource.getTarget();
// returning the object to the pool
targetSource.releaseTarget(someOtherTask);
} catch (Exception e) {
e.printStackTrace();
}
}
}
