我在我的应用程序中使用 Hibernate + Oracle

我在下面的代码中收到错误

示例 1. 我的 pojo 类

public Test{

@Type(type = "blob2map")
public Map<String, String> param;


public Map<String, String> getParam() {
    return param;
}

public void setParam(Map<String, String> param) {
    this.param= param;
}

  1. 我的道类方法

    public List<BusinessObject> searchByExample(Class<BusinessObject> entity,
    BusinessObject example) {

return getSession().createCriteria(entity).add(
        Example.create(example)).list();
}

其中业务对象是 Test.class 和示例测试

由 hibernate 或 Oracle10gDialect 生成的查询是

从测试中选择 this_.id,this_.param where this_.param=?

完整的错误日志是

Exception in thread "main" java.sql.SQLException: ORA-00932: inconsistent datatypes: expected - got BLOB
