But,this problem seems only occurred in my computer,the project goes well in my colleague's computer. This is my xml file:

<bean id="subjectCcyDao" class="com.infohold.bdrp.sys.dao.impl.SubjectCcyDaoImpl" >
    <constructor-arg value="com.infohold.bdrp.sys.model.SubjectCcy" />
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="subjectCcyManager" class="com.infohold.bdrp.sys.service.impl.SubjectCcyManagerImpl">
    <constructor-arg ref="subjectCcyDao" />
    <property name="subjectCcyDao" ref="subjectCcyDao" />
</bean>
<bean id="subjecCcyAction" class="com.infohold.bdrp.sys.action.SubjecCcyAction" parent="baseAction" scope="prototype">
    <property name="subjectCcyManager" ref="subjectCcyManager" />
    <property name="subjectDictManager" ref="subjectDictManager" />
</bean>

When I comment out this xml,the error missed.But i still can't find out the error. I google this problem all day long and can't find the answer.So,can anyone tell me the reason?Thank you.

EDIT (2016/02/22): I confirm that in my case this issue has been solved by migrating to Spring 3.1.4

---

I have no clean solution, but have some clues.

This error started to happen when I switched from Java 1.7.0_75 to Java 1.8.0_74. I suspect it has something to do with changes in a reflections implementation coming with Java 8.

We use Spring 3.1.3 and I believe this issue might be fixed in 3.1.4 according to this - https://jira.spring.io/browse/SPR-9330

When I explored the stacktrace I noticed this error occurs when the Spring Security tries to find @Secured annotations in your code. This can be disabled (if you don't really need it) by setting secured-annotations to disabled, e.g.:

<security:global-method-security secured-annotations="disabled" />

Answer 2

Are you sure that the class name has the correct spelling?

class="com.infohold.bdrp.sys.action.SubjecCcyAction"

Should that be

class="com.infohold.bdrp.sys.action.SubjectCcyAction"

That is 'Subject' with a 't', like the others.

Answer 3

if you are using spring integration you have to create setter method of that class object and configure in application context.xml file
