转换器不起作用，不按标准进行操作

Question

我是新来的^^

我正在使用一个db，其中boolean注册为VARCHAR（3）所以我做了一个转换器：

import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter
public class BooleanToStringConverter implements
    AttributeConverter<Boolean, String> {

@Override
public String convertToDatabaseColumn(Boolean value) {
    if (value == null)
        return "";
    else if (value)
        return "OUI";
    else
        return "NON";

}

@Override
public Boolean convertToEntityAttribute(String value) {
    if (value == null)
        return null;
    else if (value.trim().equals("OUI"))
        return true;
    else if (value.trim().equals("NON"))
        return false;
    else if (value.trim().equals(""))
        return null;
    else
        throw new IllegalStateException("Invalid boolean character: "
                + value);
}
}

我把我的注释@Convert：

public class Institution extends AbstractHREntity {

@Column(name = "IDOU00")
private String code;
@Column(table = "ZEXX", name = "LBOULG")
private String libelle;
@Column(table = "ZEXX", name = "LBOUSH")
private String abreviation;
@Column(table = "ZEYY", name = "LIBEXL")
private String libelleLong;
@Convert(converter = BooleanToStringConverter.class)
@Column(table = "ZEZZ", name = "ESTBUDGET", length = 3)
private Boolean isBudget;[/CODE]

但是当我按照标准提出请求时：

public List<Institution> findInstitutions(RechercheInstitutionData datas) throws DaoException{
    List<Institution> resultList = new ArrayList<Institution>();
    DetachedCriteria criteria = DetachedCriteria.forClass(Institution.class, "institution");

    if(null!=datas.getInstitutionSearched())
    {
        if (StringUtils.isNotBlank(datas.getInstitutionSearched().getLibelleLong())){
            criteria.add(Restrictions.like("institution.libelleLong", datas.getInstitutionSearched().getLibelleLong().toUpperCase(), MatchMode.START));             
        }
        if (StringUtils.isNotBlank(datas.getInstitutionSearched().getAbreviation())){
            criteria.add(Restrictions.like("institution.abreviation", datas.getInstitutionSearched().getAbreviation().toUpperCase(), MatchMode.START));             
        }
        if (StringUtils.isNotBlank(datas.getInstitutionSearched().getLibelle())){
            criteria.add(Restrictions.like("institution.libelle", datas.getInstitutionSearched().getLibelle(), MatchMode.START).ignoreCase());              
        }
        if (StringUtils.isNotBlank(datas.getInstitutionSearched().getCode())){
            criteria.add(Restrictions.like("institution.code", datas.getInstitutionSearched().getCode(), MatchMode.START));             
        }
        criteria.addOrder(Order.asc("institution.code"));
    }
    resultList = find(criteria);
    return resultList;
}

我发生了这个错误：

看起来它没有使用我的转换器，我试过断点它没有进入我的转换器...在转换器文档中它说“你要做的就是把@convert”但显然没有..请帮助我真的输了。
