Question

我有一个用于登录的简单表单。我正在为<form:input... /> x获取HTTP状态500

    <form:form modelAttribute="client" method="POST" id="login" action="/login" class="register-form">
        <form:input path="username" type="text" id="username" placeholder="username" />
        <form:input path="password" id="password" type="password" placeholder="password" />
        <button type="submit" value="Sign in">Sign in </button>>
        <p class="message">
            Not registered?
            <a href="#">Create an account</a>
        </p>
        <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
        <span>${success }</span>
    </form:form>

错误消息：message An exception occurred processing JSP page /WEB-INF/jsp/clogin.jsp at line 123。第123行是<form:input path="username" type="text" id="username" placeholder="username" />。

错误日志：

我有什么遗失的东西吗？

Answer 1

在控制器中添加此ligne：

@ModelAttribute("client")
public Client client(){
  return new Client();
}

在你的jsp中

<form:form action="/login" model modelAttribute="client" ...>
