Question

When I add an autowire into my controller I get the following exception:

var form1 = me.getStockTransferRequestPage();
    var model = Ext.create("net.omobio.dialog.dialogcc.model.StockTransferDetails", form1.getValues());

    // validate form fields
    var errors = model.validate();

    if (!errors.isValid()) {
        // loop through validation errors and generate a message to the user
        errors.each(function (errorObj){
            //errorString += errorObj.getField() + " " + errorObj.getMessage();
            console.log('7777777777777777777    '+errorObj.getField());
            if (!Ext.getCmp(errorObj.getField().toString()).isHidden()) {
                var s = Ext.String.format('field[name={0}]',errorObj.getField());
                form1.down(s).addCls('invalidField');
            }

        });
        Ext.Msg.alert('','stock_transfer.errors.required_fields_empty');
    }

I am not sure how to solve this any suggestions please? I was wondering whether or not it was something to do with my component scan in the application context? My controller:

你有很多xml文件造成了很多混乱。首先配置简单的mvc然后添加安全性和过滤器。对于简单的mvc你的web.xml看起来如下所示

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

的applicationContext.xml

<context:component-scan base-package="com.projectShaun" />
    <mvc:annotation-driven />

调度-servlet.xml中

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>

<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />
