I have a web application which fails while deployment. I get following error:

我的CustomLoginSuccessHandler类是这样的：
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.
我是 spring 的新手，但我想这是由于 bean 依赖项配置。
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?
1. spring bean的依赖顺序是什么，是否使用web.xml中的XML配置顺序？
2. 假设我在 XML 文件中引用 bean A，该文件在下面定义的引用位置，会产生任何问题吗？

My LDAPUtil class is like:
我的 LDAPUtil 类是这样的：
private LdapOperations ldapTemplate;
public void setLdapTemplate(LdapTemplate ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
采纳答案by Serge Ballesta
The error gives useful elements. The cause (last error in chain) is (stripped down string) :
该错误提供了有用的元素。原因（链中的最后一个错误）是（精简字符串）：
Error creating bean with name 'ldapContact' ... Failed to convert property value of type '$Proxy213 implementing ... LdapOperations ...' to required type '....LdapTemplate' for property 'ldapTemplate'
创建名为“ldapContact”的 bean 时出错...无法将“$Proxy213 实现... LdapOperations ...”类型的属性值转换为属性“ldapTemplate”所需的类型“....LdapTemplate”
You did not show LdapUtilsource, but from CustomSuccessHandlerand the error, I presume it contains somewhere :
您没有显示LdapUtil源代码，但是来自CustomSuccessHandler和错误，我认为它包含某处：
@Autowired
LdapTemplate ldapTemplate;
The error indicates that there is an AOP proxying mechanisme around the ldapTemplatebean.
该错误表明ldapTemplatebean周围存在 AOP 代理机制。
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 ldapTemplatethrough an interface :
这不是问题，除了默认情况下 Spring AOP 使用 JDK 代理，并且代理实现了所有接口，但不扩展原始类。您应该能够ldapTemplate通过接口引用来修复错误：
@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.
或者，您可以要求 Spring 使用 cglib 代理，它通过<aop:config proxy-target-class = "true">在 xml 文件<aop:aspectj-autoproxy proxy-target-class="true"/>中使用（或者如果您正在使用注释）来扩展原始类。但这需要 cglib jars 在路径上，并且由于您可以使用接口，我建议您使用第一个解决方案。
EDIT :
编辑 ：
Your edited post shows how you load ldapTemplatein LdapUtil. You load it as a class, when you should use the interface that way :
你的后期编辑展示了如何加载ldapTemplate在LdapUtil。当你应该以这种方式使用接口时，你将它作为一个类加载：
private LdapOperations ldapTemplate;
public void setLdapTemplate(LdapOperations ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
