Question

I have create a Service and loading it using @Service(“amazonService”).
My application context is loading this service using
I am configuring the properties using

<bean id="propsHolder"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreResourceNotFound" value="true" />
    <property name="locations">
        <list>
            <value>classpath:/applicationConfig.properties</value>

        </list>
    </property>

</bean>

In my Amazon service i do:

    public class AmazonServiceImpl implements FileStorageService {

    private AmazonS3 amazonClient;
    @Value("${abcxyz}")
    public String bucketName ;

And my props file has a property abcxyz = my-bucket

But this fails badly with the following exception:

 Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: public java.lang.String com.flipswap.service.impl.AmazonServiceImpl.bucketName; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [java.lang.String] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Everyone is able to do this successfully and even i succeeded it in a plain java sample. But running in MVC fails.

Any idea?

Answer 1

I got it! Actually the App had configured its custom XMLWebapplication context in web.xml as its spring context loader listener.

This was not passing in the call to the super method which was actually responsible for registering @Value annotation processors.
