Không tìm thấy Setter cho lớp thuộc tính

Question

Bây giờ, tôi viết ứng dụng mẫu với jsf, spring và ibatis.I sử dụng facelets và viết template.xhtml, header.xhtml, menu.xml, login.xhtml và trang chủ. Sau khi đăng nhập, tôi đã tìm thấy lỗi này.

Trong trình duyệt,

Setter not found for property class 
    + Stack Trace 
    + Component Tree 
    + Scoped Variables 

Trong Console,

21:01:20,890 SEVERE [viewhandler] Error Rendering View[/view/SPAR02.xhtml]

template.xml My,

<div class="head">  
    <ui:include src="header.xhtml"></ui:include> 
    <div> 
    <table border="0" class="normal" height="500px" align="center" bgcolor="#F4FFE4">

     </td> 
     </tr> 
     </table> 
    </div> 
    <ui:include src="footer.xhtml"></ui:include> 

trang chủ của tôi (SPAR02.xhtml),

<ui:define name="head"> 
    <title>Top Menu</title> 
    </ui:define> 
    <ui:define name="body"> 
    <font size="5">Welcome</font> 
     You can search user informations, update or delete them and can add new user. 
    </ui:define> 

Tôi không thể tìm thấy điều gì sai, bất kỳ ai cũng giúp tôi.

Answer 1

Facelets đang cố đặt thuộc tính class thành thành phần không chấp nhận thuộc tính này. Hầu hết thời gian, thuộc tính cho thuộc tính HTML class là styleClass.

Tôi không thấy sự cố trong mã mà bạn cung cấp cho chúng tôi. Vấn đề có thể là bất cứ nơi nào trong trang facelets.

Xem this question for more information.

Answer 2

tôi đã có lỗi tương tự,

public static void setFileName(String fileName) { 
    LogFile.fileName = fileName; 
} 

trong mùa xuân

<bean id ="logfile" class = "A.B.C.LogFile" > 
    <property name ="fileName" value ="${fileName}" /> 
</bean> 

Giải pháp là để chỉ loại bỏ tĩnh từ phương pháp này:

// without static 
public void setFileName(String fileName) { 
    LogFile.fileName = fileName; 
} 

sau đó ông có thể thiết lập nó :)
