java - 重置 spring url。提交表单两次后附加 URL

Question

<form:form action="register/student.htm" method="post" modelAttribute="registerForm">
.....
</form:form>

当我最初提交此表单时，网址为

“loclhost:8080/SpringSchool/register/student.htm”

如果提交失败并且我再次提交，新的 url 将被附加并变为:

“loclhost:8080/SpringSchool/register/register/student.htm”

结果我收到 404 错误。如何重置 url，以便不附加 url 或者只是基本上使其工作？

@Controller
@RequestMapping("/register")
public class RegisterController {

@RequestMapping(method=RequestMethod.GET)
    public ModelAndView registerPage(){

        return new ModelAndView("registerStudent", "registerForm", new Student());
    }


    @RequestMapping(value="/student", method = RequestMethod.POST)
    public ModelAndView registerStudent(@ModelAttribute("registerForm") final Student student, RedirectAttributes redirectAttr){
            ....
            return new ModelAndView("registerStudent", "registerForm", student);            

    }

查看解析器

<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
</bean>

如果您从“/”开始 URL，那么它表示上下文的根，但如果您从单词开始 URL，则意味着“从当前路径”。如果您在 URL 中添加“/”，您的问题就应该得到解决:

<form:form action="/${pageContext.request.contextPath}/register/student.htm" method="post" modelAttribute="registerForm">
.....
</form:form>
