發送一個Ajax請求的Spring MVC

Question

我有方法處理返回值的問題，在Spring MVC中 我有一個網格，當一排我必須表明行的詳細信息，用戶點擊。 我不想送行ID的URL，當我使用@PathVariable一切工作完美

我使用的jqGrid在我的JSP中獲得所選行的id

onSelectRow: function(id) { 
    document.location.href = "/customer/" + id; 
} 

我的控制器：

@RequestMapping("/customer") 
@Controller 
public class CustomerController { 

    final Logger logger = LoggerFactory.getLogger(CustomerController.class); 

    @Autowired 
    private CustomerService customerService; 

    @Autowired 
    MessageSource messageSource; 


@RequestMapping(value = "/{id}", method = RequestMethod.GET) 

公共字符串顯示（驗證認證，@PathVariable（ 「ID」）INT ID，型號uiModel，語言環境的語言環境）{

User user = (User) authentication.getPrincipal(); 
String result = null; 
try { 
    if (user != null) { 
     if (user.getRole().getRoleType().equalsIgnoreCase("ADMIN")) { 
      Customer customer = customerService.getCustomerById(id); 
      uiModel.addAttribute("customer", customer); 
      result = "customer/show"; 
     } else 
      result = "/customer/all"; 
    } 
} catch (Exception e) { 
    uiModel.addAttribute("message", new Message("error", 
      messageSource.getMessage("customer_get_all_fail", new Object[]{}, locale))); 
    e.getStackTrace(); 

} 
return result; 

}

我的Apache配置瓦負載詳細信息頁面：

<definition extends="default" name="customer/show"> 
<put-attribute name="body" 
    value="/WEB-INF/views/customer/showCustomerData.jspx" /> 

和我的servelt-context.xml的

 <mvc:annotation-driven/> 
    <mvc:resources location="/, classpath:/META-INF/web-resources/" mapping="/resources/**"/> 

    <tx:annotation-driven/> 
    <context:annotation-config/>

       <!-- Scan views directory for Tiles configurations --> 
       <value>/WEB-INF/views/**/views.xml</value> 
      </list> 
     </property> 
    </bean> 

    <bean id="themeResolver" class="org.springframework.web.servlet.theme.CookieThemeResolver" 
      p:cookieName="theme" p:defaultThemeName="standard"/> 

    <bean id="themeSource" class="org.springframework.ui.context.support.ResourceBundleThemeSource"/> 
</beans> 

和任何工作完美，但我有在請求對象的URL發送給我的數據，而不是

我的代碼 在JSP：

onSelectRow: function(id) { 
    $.ajax({ 
     url : '${showSelectedCustomer}', 
     dataType: 'JSON', 
     data:{ id: id }, 
     type:'POST', 
     success: function(response) { 
     } , 
     error : function(r) { 
     } 
    }); 
} 

和我的方法處理：

@RequestMapping(value = "/showSelectedCustomer", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE) 

// @ ResponseBody 公共字符串showSelectedCustomer（ 認證的認證， @RequestParam串ID， 型號uiModel，語言環境區域設置）{

User user = (User) authentication.getPrincipal(); 
Customer customer = null; 
Map<String, Object> map = new HashMap<String, Object>(); 
try { 
    if (user != null) { 
     if (user.getRole().getRoleType().equalsIgnoreCase("ADMIN")) { 
      customer = customerService.getCustomerById(Integer.valueOf(id)); 
      uiModel.addAttribute("customer", customer); 
     } 
    } 
} catch (Exception e) { 
    uiModel.addAttribute("message", new Message("error", 
      messageSource.getMessage("customer_get_all_fail", new Object[]{}, locale))); 
    e.getStackTrace(); 

} 
return "customer/show"; 

}

我的方法處理程序被調用但在這之後任何反應。 我的觀點是showCustomerData.jspx，顯示客戶的細節沒有被加載。

請讓我知道我該怎麼做，我的問題是什麼？ 當我使用我的數據與Ajax時，我應該如何返回我的返回值以查看詳細信息頁（showCustomerData.jspx） 當我更改我的方法處理程序以返回具有map.put（「message」，「success」）數據的地圖，我的ajax成功函數被調用，但我不知道我怎麼可以把它重定向顯示我的詳細信息頁面

謝謝

Answer 1

您首先需要創建CustomerInput POJO像下面

class CustomerInput{ 
private Integer id; 
//setter getter 
} 

然後創建像控制器方法下面

@ResponseBody public String showSelectedCustomer(Authentication authentication, @RequestBody CustomerInput customerInput, Model uiModel, Locale locale) { 

}
