Failure running spring application : NoSuchBeanDefinitionException

Question

I have some trouble running a java spring application : main component is fr.sgcib.cva.accounting.Computation inside Accounting.jar.

I am trying this command :

java -cp spring/*:./*:spring-core-3.1.1.RELEASE.jar:spring-context-3.1.1.RELEASE.jar:spring-beans-3.1.1.RELEASE.jar:log4j-1.2.16.jar:commons-lang3-3.1.jar:commons-logging-1.1.1.jar:spring-asm-3.1.1.RELEASE.jar:spring-expression-3.1.1.RELEASE.jar:.:Accounting.jar fr.sgcib.cva.accounting.Computation 3

The applicationContext.xml file is located in spring/, and looks like this :

<?xml version="1.0" encoding="UTF-8"?>

<util:properties id="jdbcProps" location="jdbc.properties" />

         <value>classpath:jdbc.properties</value>
        </list>
    </property>
</bean>

The main class Computation.java :

package fr.aaa.accounting;

@Component
public class Computation {
static Logger logger = Logger.getLogger(Computation.class);

@Autowired
Runs runs;

public Computation() {
}

public Run initialize(Long runId) {
    Run run = runs.getRun(runId);
    return run;
}

public Runs getRuns() {
    return runs;
}

public void setRuns(Runs runs) {
    this.runs = runs;
}

/**
 * @param args
 */
public static void main(String[] args) {
    Long runId = Long.parseLong(args[0]);
    logger.info("RUNNING RUN_ID " + runId);

    ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");
    Computation computer = context.getBean(Computation.class);
    /* etc. */

}

The console output I get when running the above command :

10:44:41,745 INFO main fr.aaa.accounting.Computation:299 - RUNNING RUN_ID 3
10:44:41,872 INFO main org.springframework.context.support.ClassPathXmlApplicationContext:495 - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@e0b6f5: startup date [Mon Mar 10 10:44:41 CET 2014]; root of context hierarchy

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [fr.aaa.accounting.Computation] is defined: expected single bean but found 0:

    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1101)
    at fr.aaa.accounting.Computation.main(Computation.java:302)

Why can't the JVM find that bean ?

Answer 1

Change this line:

 ApplicationContext context = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml);

to this:

  ("classpath:applicationContext.xml)  // without the star

When using the start you are basically creating an empty application context when the file could not be found.
