请告诉我哪里有问题？这是我的项目:https://github.com/intrade/inventory 我尝试使用java配置启用Spring安全性,当我尝试将类型的依赖项MyCustomUserDetailsService注入我的SecurityConfig类时,我得到一个异常:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.springapp.mvc.services.MyCustomUserDetailsService com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService; nested exception is java.lang.IllegalArgumentException: Can not set com.springapp.mvc.services.MyCustomUserDetailsService field com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService to com.sun.proxy.$Proxy38

我尝试在JSP中创建表单并且输入字段有一个问题.这是我的JSP页面的一部分:

<section>
    <div class="container">
        <h4>Add new PC or Laptop</h4>
        <div class="form">
            <form:form method="post" action="/app/pc/add" class="form-horizontal" modelAttribute="pc" role="form">
                <div class="control-group">
                    <label class="control-label" for="number">PC Number</label>
                    <div class="controls">
                        <form:input id="number" placeholder="Number" path="number">
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="cpu">CPU</label>
                    <div class="controls">
                        <form:input id="cpu" placeholder="CPU" path="cpu">
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="hdd">HDD size</label>
                    <div class="controls">
                        <form:input id="hdd" placeholder="HDD size" path="hdd">
                    </div>
                </div>
                <div class="control-group">

                            </c:forEach>
                        </select>
                    </div>
                </div>
                <div class="control-group"> …

当我尝试运行项目时,Tomcat返回一个异常.

有人可以帮忙解决这个问题吗？配置类:https://github.com/intrade/inventory/blob/master/src/main/java/com/springapp/mvc/InitApp/SecurityConfig.java
