如何使用Hibernate保存或检索数组列 [英] How to save or retrieve an array column using Hibernate

问题描述

我使用 Postgres ，并且我有一列 ufsinss character（2）[] like 阵列。我创建了 userType 模型来使用，因为我在 google 中发现了一些文章，指出了解决这个问题的方法，因为 Hibernate 没有本地方式来处理它。

我的 userType code>有这两个代码。

  public static final String TYPE =arrayStringType; 
 
 public Class< String []> returnedClass（）{
 return String []。class; 
 
 $ b @Override 
 public Object nullSafeGet（ResultSet rs，String [] names，SessionImplementor sessionImpl，Object obj）抛出HibernateException，SQLException {
 
 Array array = rs.getArray（names [0]）; 
返回NullUtil.isNull（数组）？ null：（String []）array.getArray（）; 
 
 $ b @Override 
 public void nullSafeSet（PreparedStatement st，Object value，int index，SessionImplementor sessionImpl）throws HibernateException，SQLException {
 
连接连接= st.getConnection（）; 
 String [] stringArray =（String []）value; 
 Array array = connection.createArrayOf（character，stringArray）; 
 st.setArray（index，array）; 
} 
  

我的模型实体是这样声明的：

  @Type（type = ArrayStringType.TYPE）
 private String [] ufsInss; 
  

但是我收到错误：

更新我的代码之后

  @Override 
 public void nullSafeSet（PreparedStatement st，Object value，int索引，SessionImplementor sessionImpl）抛出HibernateException，SQLException {
 
连接连接= st.getConnection（）; 
 String [] stringArray =（String []）value; 
 
 if（NullUtil.isNull（stringArray））{
 st.setNull（index，IntegerType.INSTANCE.sqlType（））; 
} else {
 Array array = connection.createArrayOf（varchar，stringArray）; 
 st.setArray（index，array）; 
} 
 
} 
  

我收到新错误

上面有更多的行错误，但是限制了。

$ b $ 您有两个问题：使用JDBC3驱动程序;在您的 createArrayOf 中使用无效类型名称字符 / code>呼叫。您必须使用与您的表定义方式相匹配的有效SQL类型，例如 varchar 或 text 。

Try：

  Array array = connection.createArrayOf（text，stringArray）; 
  

（根据您在数据库中声明数组的方式进行调整）。

I use Postgres and I have one column ufsinss character(2)[] like array. I created userType model to use, because I found some posts in google indicating the way to deal with this problem, because Hibernate doesn´t have native ways to deal with it.

My userType have this two code.

public static final String TYPE = "arrayStringType";

    public Class<String[]> returnedClass() {
        return String[].class;
    }

    @Override
    public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor sessionImpl, Object obj) throws HibernateException, SQLException {

        Array array = rs.getArray(names[0]);
        return NullUtil.isNull(array) ? null : (String[]) array.getArray(); 
   }

    @Override
    public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor sessionImpl) throws HibernateException, SQLException {

        Connection connection = st.getConnection();
        String[] stringArray = (String[]) value;
        Array array = connection.createArrayOf("character", stringArray);
        st.setArray(index, array);      
    }

My model entity is declared like this:

@Type(type = ArrayStringType.TYPE)
private String[] ufsInss;

But I´m getting error:

After updating my code

@Override

    Connection connection = st.getConnection();
    String[] stringArray = (String[]) value;

    if (NullUtil.isNull(stringArray)) {

        Array array = connection.createArrayOf("varchar", stringArray);
        st.setArray(index, array);      
    }

}

Above had more lines error but SO limits.

解决方案

You had two problems:

• You were using the JDBC3 driver; and

• You were using the invalid type name character in your createArrayOf call. You must use a valid SQL type that matches how your table is defined, e.g. varchar or text.

Try:

Array array = connection.createArrayOf("text", stringArray);

(adjust depending on how you declared your array in the database).

这篇关于如何使用Hibernate保存或检索数组列的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
