当调用阿贾克斯调用不警报数据

Question

我用spring mvc和ajax.i传递列表从控制器，我想警告它从ajax调用，但警报不从列表中获取数据，但HTML代码。

控制器：

@RequestMapping("/AddUpdateCustomer") 
    public String redirectCustomer(Map<String, Object> map) { 
     map.put("customerList", customerService.listCustomer()); 

     return "AddUpdateCustomer"; 
    } 

Ajax调用：

<script type="text/javascript"> 

     function LoadDataToThegrid() { 

     // get the form values 

     //var name = $('#name').val(); 

     //var education = $('#education').val(); 



     $.ajax({ 

     type: "POST", 

     url: "AddUpdateCustomer.html", 

     //data: "name=" + name + "&education=" + education, 

     success: function(data){ 

     // we have the response 

     alert(data); 

     }, 

     error: function(e){ 

     alert('Error: ' + e); 

     } 

     }); 

     } 

     </script> 

被ALRT为：

全HTML代码给出的警报，但我想要得到的数据列表的警报。

网站XML：

     <servlet-name>spring</servlet-name> 
     <url-pattern>/</url-pattern>

为spring-servlet.xml

Answer 1

添加注释@ResponseBody

@RequestMapping("/AddUpdateCustomer") 
@ResponseBody 
public String redirectCustomer(Map<String, Object> map) { 
    map.put("customerList", customerService.listCustomer()); 
    return "AddUpdateCustomer"; 
} 

Answer 2

我不认为呼叫到达您的控制器。 ajax调用实际上是获取AddUpdateCustomer.html的html。并发布您的web.xml和dispatcher-servlet.xml配置以获得进一步的说明。

Answer 3

你可以让你的控制器注释与@RestController 或者你可以注释与@ResponseBody的处理方法如下图所示

@RequestMapping("/AddUpdateCustomer") 
@ResponseBody 
public List<Customer> redirectCustomer() { 
     return customerService.listCustomer(); 
}
