<%@ taglib prefix="sf" uri="http://www.springframework.org/tags/form" %> <%@ page contenttype="text/html;charset=utf-8" language="java" %> <html xmlns:th="http://www.thymeleaf.org" xmlns="http://www.w3.org/1999/xhtml"> <head>     <title>create new account</title>     <link th:href="@{/resources/css/loginform.css}" href="/resources/css/loginform.css" rel="stylesheet"           type="text/css"/> </head> <body>  <form action="#" th:action="@{/createnewaccount}" th:object="${user}" method="post">     <table>         <tr>             <td>name:</td>             <td><input type="text" th:field="*{username}" /></td>             <td th:if="${#fields.haserrors('name')}" th:errors="*{username}">name error</td>         </tr>         <tr>             <td>password:</td>             <td><input type="text" th:field="*{password}" /></td>             <td th:if="${#fields.haserrors('age')}" th:errors="*{password}">password error</td>         </tr>         <tr>             <td><button type="submit">submit</button></td>         </tr>     </table> </form>  </body> </html>

now can see errors intellij ide showing:

user.java

package com.practice.domain;  import javax.validation.constraints.notnull; import javax.validation.constraints.size;  /**  * created drewjocham on 8/30/15.  */  public class user {      @notnull     @size(min = 2, max = 30)     private string username;     @notnull     private string password;      public string getusername() {         return username;     }      public void setusername(string username) {         this.username = username;     }      public string getpassword() {         return password;     }      public void setpassword(string password) {         this.password = password;     }      @override     public string tostring() {         return "user{" +                 "username='" + username + '\'' +                 ", password='" + password + '\'' +                 '}';     } }

the field name call haserrors needs match field name in object. so:

<td th:if="${#fields.haserrors('username')}" th:errors="*{username}">name error</td>

note haserrors('name') became haserrors('username'), and:

<td th:if="${#fields.haserrors('password')}" th:errors="*{password}">password error</td>

note haserrors('age') became haserrors('password').

as errors being highlighted in intellij, think they're misleading, , related open issue: https://youtrack.jetbrains.com/issue/idea-132738
