employeeとをプロパティとして持つテーブルがdepartmentありaddressます。JSR 300でクラスの属性を検証したいのですがaddress、住所と部門クラスの属性で検証に問題があります。これまでのところ、クラスの属性のみEmployeeが検証されています。私は何かが足りないのですか？
public class Employee {
private Integer id;
@NotEmpty(message = "First Name must not be blank.")
@Size(min = 1, max = 50)
private String firstName;
@NotEmpty(message = "Last Name must not be blank.")
@Size(min = 1, max = 50)
private String lastName;
@Digits(message = "Salary field must not be blank.", integer=32767, fraction = 2)
@NumberFormat(style = Style.NUMBER)
@NotNull(message = "Salary field must not be blank.")
private Double salary;
@Digits(message = "Select department", integer=100, fraction = 0)
@NumberFormat(style = Style.NUMBER)
@NotNull(message = "Select department")
private Integer dept_id;
@NotEmpty(message = "Select gender")
private String gender;
private boolean employeeStatus;
private Address address;
private Department department;
}
public class Address {
private Integer id;
@NotEmpty(message = "Country must not be blank.")
@Size(min = 1, max = 50)
private String country;
@NotEmpty(message = "City must not be blank.")
@Size(min = 1, max = 50)
private String city;
@NotEmpty(message = "Street must not be blank.")
@Size(min = 1, max = 50)
private String street;
private Integer emp_id;
}
public class Department {
private String name;
private Integer id;
}

さらに、給与フィールドでランダムな文字列を試してみると、例外が発生します。
Failed to convert property value of type java.lang.String to required type java.lang.Double for property salary; nested exception is java.lang.NumberFormatException:
この例外を取り除く方法は？
