Spring mvc 提交表单时，表单值未进入控制器

我试图使用SpringDataJPA存储库方法将4个表单字段名称、年龄、位置和地址插入数据库。当我将表单提交到操作中时，控制器不能接收提交的值。在控制器操作中获取null。这里我尝试使用spring引导和spring数据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 
    }

我的表格是

<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>

我被印刷所困扰

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

但不是通过这种方法访问。这种接收方式是否不正确？使用这种方法我能做什么？否则，是否有使用对象类型接收实现表单值的第二种方法

我的驾驶课是

包com.central.model

导入java.io.Serializable

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;
}
}

更改驱动程序实体，如下所示：

@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;
}
}

什么是你的驱动程序对象。驱动程序是我的对象，我根据动作定义创建的。当我调试函数开头的接收值时，得到的是null值。当使用“@modeldattribute Driver-Driver”代码时，它没有接收到。您能显示您的驱动程序类吗？我添加了驱动程序类，并编辑了问题。此新更改正在运行。谢谢您的回复，先生。很高兴能为您提供帮助

@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;
}
