我到处搜索这个错误，并查看每个单独的线程在同一个标题，在我的代码中改变了很多，但仍然存在错误。客户端发送的请求在语法上是不正确的，Spring with Hibernate Annotations
它说：
HTTP Status 400 -
type Status report
message
description The request sent by the client was syntactically incorrect.
Apache Tomcat/7.0.35
我的控制器代码：
@RequestMapping(value = "/manageInventory.htm", method = RequestMethod.GET)
public ModelAndView manageInventory(HttpSession session) {
ArrayList<Product> products = new ArrayList<Product>();
Manufacturer manufacturer = (Manufacturer) manufacturerDAO
.getByUsername(((UserAccount) session.getAttribute("user"))
.getUsername());
products = productDAO.getProductListByManufacturer(manufacturer
.getManufacturerName());
System.out.print(products.get(0).getProductName());
ModelAndView view = new ModelAndView("manageInventory");
view.addObject("products", products);
InventoryItem inventoryItem = new InventoryItem();
view.addObject("inventoryItem", inventoryItem);
return view;
}
@RequestMapping(value = "/manufacture.htm", method = RequestMethod.POST)
public ModelAndView manufactureProduct(HttpSession session, BindingResult result,
@ModelAttribute("inventoryItem") @Valid InventoryItem inventoryItem) {
System.out.print(result.getErrorCount()+" "+result.getAllErrors());
ModelAndView view = null;
if(!result.hasErrors())
{
Manufacturer manufacturer = manufacturerDAO
.getByUsername(((UserAccount) (session.getAttribute("user")))
.getUsername());
inventoryItem.setAvailability(true);
inventoryItem.setManufacturer(manufacturer);
manufacturer.getInventory().add(inventoryItem);
manufacturerDAO.update(manufacturer);
view = new ModelAndView("done");
}
else
{
view = new ModelAndView("manageInventory");
}
return view;
}
第一种方法是增加inventoryItem到模型中，我取，对于验证之后。
我使用的地砖等等，我给这家瓷砖是：
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<body>
<h2>Add Inventory</h2>
<br />
<form:form modelAttribute="inventoryItem" action="manufacture.htm" method="post">
<table>
<tr>
<td>Select Product:</td>
<td><form:select path="product">
<c:forEach var="product" items="${products}">
<form:option value="${product}">${product.productName}</form:option>
</c:forEach>
</form:select></td>
<td>Select Quantity:</td>
<td>
<form:input path="quantity" placeholder="Quantity"/><br />
<font color="red"><form:errors path="quantity"/> </font>
</td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Manufacture">
</td>
</tr>
</table>
</form:form>
</body>
我的POJO具有以下验证：
@NotNull
private int quantity;
请帮助。提前致谢。
