提交表单时未在控制器中获取表单值

Question

我正在尝试使用spring data JPA repository方法在数据库中插入4个表单字段name、age、location和address。当我将表单提交到操作时，控制器不会无法接收提交的值。在控制器操作中获取null。在这里，我尝试使用spring、spring boot和spring data JPA。下面是我的控制器,

@RequestMapping(value="/driverSubmit", method=RequestMethod.POST)
public ModelAndView driverSubmit(@ModelAttribute Driver driver, Model model) 
    {
        model.addAttribute("driver", driver);
        driverRepo.save(driver);
        return new ModelAndView("redirect:/dHome"); //to home page insertoin 
    }

我的形式是，

<form action="driverSubmit" method="post" >
    <table width="300px" height="200px" align="center"> 
        <tr> 
            <td>
                <b> Name </b>
            </td>
            <td>
                <input type="text" name="name" />
            </td>
        </tr>
        <tr>
            <td>
                <b> Age</b>
            </td>
            <td>
                <input type="text" name="age"/>
            </td>
        </tr>
        <tr>
            <td>
                <b> Address</b>
            </td>
            <td>
               <input type="text" name="address"/>
            </td>
        </tr>
        <tr>
            <td>
                <b> Location</b>
            </td>
            <td>
                <input type="text" name="location" />
            </td>
        </tr>
    </table>
        <div>
            <input type="submit" value="Submit"/> 
        </div>
</form>

@ModelAttribute Driver driver

driver.name;
driver.age;
driver.address;
driver.location;

导入javax.persistence.*；

@Entity
@Table(name = "drivers")

public class Driver implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Integer id;

@Column(name = "name")
public String name;

@Column(name = "age")
public Integer age;

@Column(name = "address")
public String address;

@Column(name = "location")
public String location;

public Driver() {
}

public Driver(String name, Integer age, String address , String location ) {
    this.name = name;
    this.age = age;
    this.address = address;
    this.location = location;
}
}

Answer 1

如下所示更改驱动程序实体：

@Entity
@Table(name = "drivers")

public class Driver implements Serializable {
    private  Integer id;
    private String name;
    private Integer age;
    private String address;
    private String location;


@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

@Column(name = "name")
public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

   @Column(name = "age")
    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

  @Column(name = "address")
    public String getAddress() {
        return address;
    }


    public void setAddress(String address) {
        this.address = address;
    }

@Column(name = "location")
    public String getLocation() {
        return location;
    }

    public void setLocation(String location) {
        this.location = location;
    }




public Driver() {
}

public Driver(String name, Integer age, String address , String location ) {
    this.name = name;
    this.age = age;
    this.address = address;
    this.location = location;
}
}
