无法转换类型 [java.lang.String] 的属性值

Question

我的 spring 应用程序在将“日期”保存到“数据库”时遇到问题。哪里出错了？

错误

无法将 [java.lang.String] 类型的属性值转换为 属性bornDate所需的类型[java.sql.Date]；嵌套异常 是 java.lang.IllegalArgumentException：无法解析日期： 无法解析的日期：“2016-11-02”

mysql

use lifecalc;
create table Man (
manId int not null auto_increment primary key,
name varchar(30) not null,
bornDate date,
lastDate date
);
insert into man value
(null, "Pawel Cichon", "1920-11-30", "2000-02-20");

实体

@Entity
@Table(name="Man")
public class Man {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="manId")
    private int manId;

    @Column
    private String name;

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    @Column
    private java.sql.Date bornDate;

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    @Column
    private java.sql.Date lastDate;
    //getter end setter

控制器

@Controller
@RequestMapping("/")
public class AppController {

    @Autowired
    private ManService manService;

    @ModelAttribute("man")
    public Man modelToAddMan(){
        return new Man();
    }

    @InitBinder
     public void initBinder(WebDataBinder binder) {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/mm/dd");
        dateFormat.setLenient(false);
        binder.registerCustomEditor(Date.class, new CustomDateEditor( dateFormat, true));
    }

    @RequestMapping(value="/addMan.html", method = RequestMethod.POST)
    public String addManFinish(@Valid @ModelAttribute("man") Man man, BindingResult result) {

        if(result.hasErrors()){
            return "addMan";
        } else{
            manService.addMan(man);
            return "redirect:/index.html";
        }
    }

addMan.html

<form:form method="POST" modelAttribute="man">

代替：

@DateTimeFormat(pattern = "yyyy-MM-dd")
@Column
private java.sql.Date bornDate;

使用 java.util.date：

@DateTimeFormat(pattern = "yyyy-MM-dd")
@Column
private java.util.date bornDate;
