java - springmvc 的私有(private)方法

Question

我的 Controller 中有两种方法:

1. 公共(public)方法
2. 私有(private)方法

它们都有@requestMapping并且它们都引用一个全局变量(@autowrite)。问题是第一个方法变量有值，第二个方法变量为空。

请帮助我。

    /** 
      * Both of these methods are accessible through the browser, 
      * when i ask for query1 the flowService has value but  
      * when i ask for query2 the flowService is null. 
      * My spring version is 4.2.4 
      * Created by hanxiaofei on 2017/10/12. 
      */
   public class TestController {    
       @Autowired    
       private FlowService flowService;  

       @RequestMapping(value = {"/query1"})    
       @ResponseBody    
       public CommonListResult<WorkOrderMO> query1() {
        return flowService.queryWorkOrderList(1);    
       } 

       @RequestMapping(value = {"/query2"})
       @ResponseBody
    private CommonListResult<WorkOrderMO> query2() {
        return flowService.queryWorkOrderList(1);
    }
}

用@RequestMappings注释的 Controller 方法必须是公共(public)的才能正常工作。无论如何，没有理由将请求方法设置为私有(private)，因为无论如何您都不应该自己从不同的组件调用 Controller 方法。
