title: Spring Boot Thymeleaf form binding
body: <p>I have one problem with my code...</p>
  
  <p>I wrote entity class Group, it looks like this:</p>
  
  <pre><code>@Entity
  @Table(name = "Groups")
  public class Group {
  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  private int groupID;
  private String groupName;
  private Date createDate;
  private Date modifyDate;
  
  public int getGroupID() {
      return groupID;
  }
  
  public void setGroupID(int groupID) {
      this.groupID = groupID;
  }
  
  public String getGroupName() {
      return groupName;
  }
  
  public void setGroupName(String groupName) {
      this.groupName = groupName;
  }
  
  public Date getCreateDate() {
      return createDate;
  }
  
  public void setCreateDate(Date createDate) {
      this.createDate = createDate;
  }
  
  public Date getModifyDate() {
      return modifyDate;
  }
  
  public void setModifyDate(Date modifyDate) {
      this.modifyDate = modifyDate;
  }
  
  @Override
  public String toString() {
      return "Group{" + "groupID=" + groupID + ", groupName=" + groupName + ", createDate=" + createDate + ", modifyDate=" + modifyDate + '}';       
   }
  }
  </code></pre>
  
  <p>I have a simple Controller MVC,</p>
  
  <pre><code>    @Controller
      @RequestMapping("/groups")
      public class GroupsController {
  
          @Autowired
          private GroupDAO groupDAO;
  
          @RequestMapping(value = "/list",method = RequestMethod.GET)
          public String listGroups(Model m)
          {
              m.addAttribute("groups", groupDAO.findAll());
              return "listgroup";
          }
  
          @GetMapping("/add")
          public String addGroup()
          {
              return "addgroup";
          }
  
          @PostMapping("/add")
          public String addGroupPost(@Valid @ModelAttribute(value = "grupa")Group group, BindingResult br)
          {
              if(br.hasErrors())
              {
                  return "addgroup";
              }
              System.out.println(group);
              return "listgroup";
