操作步骤：
1.配置spring支持获取本地化jdbc操作对象
<!-- nativeJdbcExtractor 和 oracleLobHandler Bean 都设置为 lazy-init="true"，这是因为 -->
<!-- nativeJdbcExtractor 需要通过运行期的反射机制获取底层的 JDBC 对象， -->
<!-- 所以需要避免在 Spring 容器启动时就实例化这两个Bean。 -->
<bean id="nativeJdbcExtractor"class="org.springframework.jdbc.support.nativejdbc.C3P0NativeJdbcExtractor"
lazy-init="true" />
2.提供oracleLobHandler
<bean id="oracleLobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler"
lazy-init="true">
<property name="nativeJdbcExtractor" ref="nativeJdbcExtractor"></property>
</bean>
3.写code，继承jdbc模板，使用execute方法内部类AbstractLobCreatingPreparedStatementCallback
private LobHandler lobHandler;
/**
* @return the lobHandler
*/
public LobHandler getLobHandler() {
return lobHandler;
}
/**
* @param lobHandler the lobHandler to set
*/
public void setLobHandler(LobHandler lobHandler) {
this.lobHandler = lobHandler;
}
public void getInsertPutImage(String txtUrl,String imgUrl) throws IOException {
//写文本
final File clobIn = new File(txtUrl);
final InputStream clobIs = new FileInputStream(clobIn);
final InputStreamReader clobReader = new InputStreamReader(clobIs);
//写图片
final File blobIn = new File(imgUrl);
final InputStream blobIs = new FileInputStream(blobIn);
getJdbcTemplate().execute(insertOracleSql, new AbstractLobCreatingPreparedStatementCallback(this.lobHandler) {
@Override
protected void setValues(PreparedStatement ps, LobCreator lobCreator)
throws SQLException, DataAccessException {
ps.setLong(1, 1l);
lobCreator.setClobAsCharacterStream(ps, 2, clobReader, (int)clobIn.length());
lobCreator.setBlobAsBinaryStream(ps, 3, blobIs, (int)blobIn.length());
}
});
clobReader.close();
blobIs.close();
}
AbstractLobCreatingPreparedStatementCallback 参数需要提供一个lobHander对象，使用时需要提供set方法。
