resultmap使用
<result property="serverip" column="SERVERIP" javaType="IP" jdbcType="INTEGER"/>
语句使用
#{serverip, javaType=IP, jdbcType=INTEGER}
handler类
public class IPTypeHandler implements TypeHandler<String> {
@Override
public void setParameter(PreparedStatement ps, int index, String ip, JdbcType jdbcType) throws SQLException {
if (ip == null) {
ps.setNull(index, java.sql.Types.INTEGER);
}
else {
ps.setInt(index, IPUtil.ip2int(ip));
}
}
@Override
public String getResult(ResultSet rs, String columnName) throws SQLException {
int l = rs.getInt(columnName);
if (rs.wasNull()) {
return null;
}
return IPUtil.int2ip(l);
}
@Override
public String getResult(ResultSet rs, int columnIndex) throws SQLException {
int l = rs.getInt(columnIndex);
if (rs.wasNull()) {
return null;
}
return IPUtil.int2ip(l);
}
@Override
public String getResult(CallableStatement cs, int columnIndex) throws SQLException {
int l = cs.getInt(columnIndex);
if (cs.wasNull()) {
return null;
}
return IPUtil.int2ip(l);
}
