Bean 属性“dipartmantId”不可读或具有无效的 getter 方法：

Question

我在这里做错了什么，我遇到了以下错误

bean 类 [com.atlas.salesapplication.entity.Employee] 的无效属性“dipartmantId”：bean 属性“dipartmantId”不可读或具有无效的 getter 方法：getter 的返回类型是否与参数类型匹配二传手？

@Entity
@Table(name = "departmant")
public class Departmant {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Integer id;
    @Column(name = "name")
    private String name;

    @OneToMany(mappedBy = "departmantId")
    private List<Employee> employeeList;

    public List<Employee> getEmployeeList() {
        return employeeList;
    }

    public void setEmployeeList(List<Employee> employeeList) {
        this.employeeList = employeeList;
    }

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

    public Integer getId(){ return id; }

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

    public String getName(){ return name; }

    public Departmant(){}

    public Departmant(Integer id, String name){
        this.id = id;
        this.name = name;
    }

    @Override
    public String toString(){
        return name;
    }
}

Employee类如下，

@Entity
@Table(name = "employee")
public class Employee {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Integer id;

    private String firstName;
    @Column(name = "lastname")
    @NotEmpty(message = "")
    @Size(min=3, message = "Last name should ane minimum 3 letters.")
    private String lastName;

Answer 1

根据你提供的错误：

Invalid property 'dipartmantId' of bean class [com.atlas.salesapplication.entity.Employee]: Bean property 'dipartmantId' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

正在尝试访问来自 Employee 类的 dipartmantId 属性。由于 Employee 类中的属性实际上称为departmantId，因此似乎有一个错字。

在您的代码中搜索dipartmantId 的用法并将其更改为departmantId

Answer 2

您的代码中有很多不同的拼写错误。我会先纠正所有这些，我敢打赌你的错误会消失（还有其他一些错误）：

• 将departmant 的所有变体重命名为department
• 将moblie 重命名为mobile
• 在您的代码中找到dipartmantId 并将其重命名为departmentId
• 考虑将包含电子邮件的列命名为email 而不是noc
