包不存在，预期。

I have a class:

我有一个类:

public class TypeOfCompressDTO {

    private int typeOfCompressId;
    private String typeOfCompress;

    public TypeOfCompressDTO() {
    }

    public TypeOfCompressDTO(int typeOfCompressId, String typeOfCompress) {
        this.typeOfCompressId = typeOfCompressId;
        this.typeOfCompress = typeOfCompress;
    }

    public int getTypeOfCompressId() {
        return typeOfCompressId;
    }

    public void setTypeOfCompressId(int typeOfCompressId) {
        this.typeOfCompressId = typeOfCompressId;
    }

    public String getTypeOfCompress() {
        return typeOfCompress;
    }

    public void setTypeOfCompress(String typeOfCompress) {
        this.typeOfCompress = typeOfCompress;
    }

}
public class TypeOf
