Angularjs 从$http调用Spring控制器方法时出现404错误

这个问题以前也有人问过，但我没有回答。所以把它贴出来。请帮忙

阅读。也看看。嘿，乔治。。。谢谢你的精彩帖子。我会处理的。到目前为止，我想让这里的ppl找出我在配置文件中是否遗漏了什么，因为根据我的检查，控制器没有被加载，所以在指定控制器/映射配置时可能存在spring配置的问题。

<context:annotation-config />
            <context:component-scan base-package="main.java.com.controller" use-default-filters="false">
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
        </context:component-scan>
        <mvc:annotation-driven />
<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/views" />
    <property name="suffix" value=".html" />
    <property name="order" value="1" />
  </bean>

    <context:annotation-config />
        <context:component-scan base-package="main.java.com.controller" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
        <mvc:annotation-driven />
        <tx:annotation-driven transaction-manager="transactionManager"/>


inside Indexcontroller.js


     $scope.login = function()
            {
                 $http.post('rest/login', $scope.loginDto).success(function(data)
                            {
                     alert('success');
                            }).error(function() 
                            {
                                alert('error while delete file.');
                            });
            };

    @Controller
    public class IndexController {
    @RequestMapping(value = "/login", method = RequestMethod.POST, consumes="application/json", produces="application/json")
        public  @ResponseBody LoginDto login(@RequestBody  LoginDto loginDto, HttpServletRequest req)  
        {
            System.out.println(loginDto.getUserName()+" :::: "+loginDto.getPassword());
            return loginDto;
        }
    }
