我有一個HashMap如下:如何顯示包含對象的HashMap的模型的值?
HashMap<String, Object> myHashMap = new HashMap<String, Object>();
的數據在它看起來像這樣:
{CompanyName=null, CompanyId=null}
我想從它遍歷這個與顯示值在我的表現層。 我把它添加到我的模型如下:公共字符串
showPage(Map model)
{
HashMap<String, Object> myHashMap = new HashMap<String, Object>();
model.put("company", myHashMap);
return "page";
}
我國JSP
<h1>${companyName}</h1>
<fieldset>
<p>
<form:label path="companyName" cssErrorClass="form-error">Issuer Name</form:label>
</p>
</fieldset>
<input type="submit" value="Next" class="round blue ic-right-arrow" />
,我得到以下錯誤:
Caused by: org.springframework.beans.NotReadablePropertyException: Invalid property 'companyName' of bean class [java.util.HashMap]: Bean property 'companyName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
似乎是一個過早的提交? – Vikdor
