Spring HTTP Status 400-客户端发送的请求在语法上不正确（添加日期输入时）

当我在jsp表单上添加日期字段时，出现此错误，但是如果没有它，它将很好地工作。

请求

http://localhost:8080/@R_673_11174@asks/docreatetask?task=hi+there&description=stucked+here&date=2014-02-21&idTaskCategory=1&idTaskPriority=1&idTaskState=1&pending=1&idUser=0&iduser_responsible=0&evaluation=aaaaaa

部分form.jsp

<form method="GET"
    action="${pageContext.request.contextPath}/docreatetask">
    <table>
        <tr>
            <td>Task</td>
            <td><input name="task" type="text" /></td>
        </tr>
        <tr>
            <td>Description</td>
            <td><textarea name="description"></textarea></td>
        </tr>
        <tr>
            <td>Date</td>
            <td><input name="date" type="date"/></td>
        </tr>

部分 Task.java 组件

@Component("task")
public class Task {

    private long id;
    private String task;
    private String description;
    private Date date;
    private Date deadline;
    private Category category;
    private Priority priority;
    private State state;
    private User user;
    private User userResponsible;
    private String evaluation;
    private date TIMESTAMP;
    privatE int pending;

部分 任务控制器

@requestMapping("/createtask")
public String createTask(Model model) {
    List<Category> categories = taskservice.getCategories();
    List<Priority> priorities = taskservice.getPriorities();
    List<State> states = taskservice.getStates();
    List<User> users = taskservice.getUsers();

    model.addAttribute("categories",categories);
    model.addAttribute("priorities",priorities);
    model.addAttribute("states",states);
    model.addAttribute("users",users);

    return "createtask";
}


@requestMapping(value="/docreatetask",method=requestMethod.GET)
public String doCreateTask(Model model,Task task) {
    System.out.println(">TaskController doCreateTask " + task);

    return "taskcreated";
}

知道这可能是什么吗？

提前致谢！
