Spring dependency issue - no matching editors or conversion strategy found
I have a web application which fails while deployment. I get following error:

I am loading my configuration XML's in web.xml using:

My CustomLoginSuccessHandler class is like:
public class CustomLoginSuccessHandler implements AuthenticationSuccessHandler {
/** The redirect strategy. */
private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();
/** The ldap contact. */
@Autowired
LDAPUtil ldapContact;
I am new to spring but i guess it is due to the bean dependencies configuration.
1. What is the sequence of spring bean dependency, does it uses
sequence of XML configuration from web.xml?
2. Suppose I refer bean A
in a XML file, which is defined below where it is refered, will it
create any problem?
EDIT
My LDAPUtil class is like:
private LdapOperations ldapTemplate;
public void setLdapTemplate(LdapTemplate ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
Answer
The error gives useful elements. The cause (last error in chain) is (stripped down string) :
Error creating bean with name 'ldapContact' ... Failed to convert property value of type '$Proxy213 implementing ... LdapOperations ...' to required type '....LdapTemplate' for property 'ldapTemplate'
You did not show LdapUtil source, but from CustomSuccessHandler and the error, I presume it contains somewhere :
@Autowired
LdapTemplate ldapTemplate;
The error indicates that there is an AOP proxying mechanisme around the ldapTemplatebean.
It is not a problem, except that by default Spring AOP uses JDK proxies, and a proxy implements all interfaces, but does not extends the original class. You should be able to fix the error by referencing ldapTemplate through an interface :
@Autowired
LdapOperations ldapTemplate;
Alternatively, you can ask Spring to use cglib proxies, that do extend original class by using <aop:config proxy-target-class = "true"> in xml file (or <aop:aspectj-autoproxy proxy-target-class="true"/> if you are using annotations). But that requires cglib jars to be on the path, and as you can use interfaces, I advice you to use first solution.
EDIT :
Your edited post shows how you load ldapTemplate in LdapUtil. You load it as a class, when you should use the interface that way :
private LdapOperations ldapTemplate;
public void setLdapTemplate(LdapOperations ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
