Spring異常 - NotReadablePropertyException：無效的屬性

我試圖創建一個表單來添加一個對象到數據庫中。Spring異常 - NotReadablePropertyException：無效的屬性

的形式

public class Module implements Serializable{ 

private static final long serialVersionUID = 8825646974241476909L; 

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
@Column(name = "module_id") 
private Long moduleId; 

@Column(name = "module_code") 
private String moduleCode; 

@Column(name = "module_name") 
private String moduleName; 


//getters and setters 

public Long getModuleId() { 
    return moduleId; 
} 

public void setModuleId(Long moduleId) { 
    this.moduleId = moduleId; 
} 

public String getModuleCode() { 
    return moduleCode; 
} 

public void setModuleCode(String moduleCode) { 
    this.moduleCode = moduleCode; 
} 

public String getModuleName() { 
    return moduleName; 
} 

public void setModuleName(String moduleName) { 
    this.moduleName = moduleName; 
}

形式

<c:url var="saveUrl" value="/admin/addModule" /> 
    <form:form modelAttribute="module" method="POST" action="${saveUrl}" name="module"> 

    <table> 

     <tr> 
     <td><form:hidden path="moduleId"/></td> 
     </tr> 

     <tr> 
     <td><form:label path="moduleCode">Module Code:</form:label></td> 
      <td><form:input path="moduleCode"/></td> 
     </tr> 


</table> 

     <input type="submit" name="submit" value="Save" /> 
</form:form>

控制器

 @RequestMapping(value = "/admin/addModule", method = RequestMethod.GET) 
public String getAdminAddModule(@ModelAttribute("module") ModelMap map) { 
map.addAttribute("module", new Module()); 

    // This will resolve to /WEB-INF/jsp/addedpage.jsp 
return "/admin/addModule"; 
}

當我試圖訪問一個錯誤不斷上來的所有屬性的形式模型。這是moduleId屬性的堆棧跟蹤錯誤。

我所有的setter和getter方法，但該錯誤持續存在。

您應該刪除@ModelAttribute對ModelMap參數。該參數由Spring自動填充，併爲您提供填充模型對象的方法，您稍後將使用map.addAttribute("module", new Module());進行填充。

刪除@ModelAttribute應該爲您解決。

是的，它修復了它。謝謝。 – user2259555 2013-05-01 20:23:50
