@Min Annotation is not working

My Entity Class property portion is given below:

@Entity
@Table(name="rules")
public class Rule {
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private long id;

    @NotEmpty
    @Size(min=4, max=128)
    @Column(length = 128, nullable = false)
    private String name;

    @Column
    private String assetType;

    @Min(value=1, message="Minimum value should be 1")
    @Column(name = "min_quantity")
    private int min_quantity;

    @Min(value=1L, message="Minimum value should be 1")
    @Column
    private int warningAt;

    @Column
    private boolean status;

In html form:

<div class="has-error">
 <form:errors path="min_quantity" />
</div>

I am getting below error during form validator:

"Failed to convert property value of type java.lang.String to required type int for property min_quantity; nested exception is java.lang.NumberFormatException: For input string: """

In my form its not showing my custom message.

@Min is applied to numbers not strings

Use 

@Length(min = 1, message = "Minimum value should be 1")
