BeanDefinitionStoreException Failed to read candidate component class

Question

Can someone tell me how to solve this issue?

I have narrowed down the problem to the pom.xml file. My project works but when I add the following dependency I get an

Answer 1

I had a similar error due to a corrupted class file -- somehow the CI build had a zero bytes class file in the jar (despite a non-zero inner class file being present, others ok) - one broken file out of ~100 classes. It might have been a disk space issue, but took a while to realise (since the class was in a dependent project jar, built by Gradle into a fat-jar for a Spring Boot project).

Answer 2

Another reason is use of Spring 3 with Java 8. Java 8 requires Spring 4.

(not specific to this question, but for those who are googling the error message)

Answer 5

How to solve this problem?

Solution1:Change spring version to >= 3.2.16.

Solution2:If your spring versin is low than 3.2.16, dont use Annotation such as :@Service @Controller and so on. Use bean.xml define a bean, the bean.xml don't contians "<context:component-scan base-package=""/>". if you must use <context:component-scan base-package=""/> please put in other bean.xml.

Answer 6

In my case I had dependencies that brought in the spring-asm dependency that conflicted with the latest Spring core. So in Dependency Hierarchy search for "asm" and exclude spring asm from all dependencies having it.

My case: 1)

<dependency>
    <groupId>org.restlet.jee</groupId>
    <artifactId>org.restlet.ext.fileupload</artifactId>
    <version>2.3.1</version>
        <exclusions>
                <exclusion>
                  <groupId>org.springframework</groupId>
                  <artifactId>spring-asm</artifactId>
               </exclusion>
        </exclusions>
</dependency>

2)

<dependency>
    <groupId>org.restlet.jee</groupId>
    <artifactId>org.restlet.ext.spring</artifactId>
    <version>2.1.2</version>
         <exclusions>
                  <exclusion>
                         <groupId>org.springframework</groupId>
                         <artifactId>spring-asm</artifactId>
                  </exclusion>
         </exclusions>
</dependency>
