示例1: extractUsingResultSet
import java.sql.Array; //導入方法依賴的package包/類
/**
* Converts an Array into a List using {@link Array#getResultSet()}. This implementation is
* recursive and can parse multi-dimensional arrays.
*/
static List<?> extractUsingResultSet(Array array, Calendar calendar) throws SQLException {
ResultSet arrayValues = array.getResultSet();
TreeMap<Integer, Object> map = new TreeMap<>();
while (arrayValues.next()) {
// column 1 is the index in the array, column 2 is the value.
// Recurse on `getValue` to unwrap nested types correctly.
// `j` is zero-indexed and incremented for us, thus we have `1` being used twice.
map.put(arrayValues.getInt(1), getValue(arrayValues, array.getBaseType(), 1, calendar));
}
// If the result set is not in the same order as the actual Array, TreeMap fixes that.
// Need to make a concrete list to ensure Jackson serialization.
return new ArrayList<>(map.values());
}
示例2: resultSetFromArray
import java.sql.Array; //導入方法依賴的package包/類
@Test public void resultSetFromArray() throws Exception {

// Create some arrays from the structs
