# Java Connector
|
||||
|
||||
## TAOS-JDBCDriver 概述
|
||||
TDengine 提供了遵循 JDBC 标准（3.0）API 规范的 `taos-jdbcdriver` 实现，可在 maven 的中央仓库 [Sonatype Repository][1] 搜索下载。
|
||||
|
||||
TDengine 为了方便 Java 应用使用，提供了遵循 JDBC 标准(3.0)API 规范的 `taos-jdbcdriver` 实现。目前可以通过 [Sonatype Repository][1] 搜索并下载。
|
||||
`taos-jdbcdriver` 的实现包括 2 种形式： JDBC-JNI 和 JDBC-RESTful（taos-jdbcdriver-2.0.18 开始支持 JDBC-RESTful）。 JDBC-JNI 通过调用客户端 libtaos.so（或 taos.dll ）的本地方法实现， JDBC-RESTful 则在内部封装了 RESTful 接口实现。
|
||||
|
||||
由于 TDengine 是使用 c 语言开发的，使用 taos-jdbcdriver 驱动包时需要依赖系统对应的本地函数库。
|
||||
|
||||
|
||||
* libtaos.so
|
||||
在 linux 系统中成功安装 TDengine 后，依赖的本地函数库 libtaos.so 文件会被自动拷贝至 /usr/lib/libtaos.so，该目录包含在 Linux 自动扫描路径上，无需单独指定。
|
||||
上图显示了 3 种 Java 应用使用连接器访问 TDengine 的方式：
|
||||
|
||||
* taos.dll
|
||||
在 windows 系统中安装完客户端之后，驱动包依赖的 taos.dll 文件会自动拷贝到系统默认搜索路径 C:/Windows/System32 下，同样无需要单独指定。
|
||||
* JDBC-JNI：Java 应用在物理节点1（pnode1）上使用 JDBC-JNI 的 API ，直接调用客户端 API（libtaos.so 或 taos.dll）将写入和查询请求发送到位于物理节点2（pnode2）上的 taosd 实例。
|
||||
* RESTful：应用将 SQL 发送给位于物理节点2（pnode2）上的 RESTful 连接器，再调用客户端 API（libtaos.so）。
|
||||
* JDBC-RESTful：Java 应用通过 JDBC-RESTful 的 API ，将 SQL 封装成一个 RESTful 请求，发送给物理节点2的 RESTful 连接器。
|
||||
|
||||
> 注意：在 windows 环境开发时需要安装 TDengine 对应的 windows 版本客户端，由于目前没有提供 Linux 环境单独的客户端，需要安装 TDengine 才能使用。
|
||||
TDengine 的 JDBC 驱动实现尽可能与关系型数据库驱动保持一致，但时序空间数据库与关系对象型数据库服务的对象和技术特征存在差异，导致 `taos-jdbcdriver` 与传统的 JDBC driver 也存在一定差异。在使用时需要注意以下几点：
|
||||
|
||||
TDengine 的 JDBC 驱动实现尽可能的与关系型数据库驱动保持一致，但时序空间数据库与关系对象型数据库服务的对象和技术特征的差异导致 taos-jdbcdriver 并未完全实现 JDBC 标准规范。在使用时需要注意以下几点：
|
||||
|
||||
* TDengine 不提供针对单条数据记录的删除和修改的操作，驱动中也没有支持相关方法。
|
||||
* 由于不支持删除和修改，所以也不支持事务操作。
|
||||
* 目前不支持表间的 union 操作。
|
||||
* 目前不支持嵌套查询(nested query)，`对每个 Connection 的实例，至多只能有一个打开的 ResultSet 实例；如果在 ResultSet还没关闭的情况下执行了新的查询，TSDBJDBCDriver 则会自动关闭上一个 ResultSet`。

## TDengine DataType 和 Java DataType
|
||||
注意：与 JNI 方式不同，RESTful 接口是无状态的，因此 `USE db_name` 指令没有效果，RESTful 下所有对表名、超级表名的引用都需要指定数据库名前缀。
|
||||
|
||||
TDengine 目前支持时间戳、数字、字符、布尔类型，与 Java 对应类型转换如下：

### 获取连接
|
||||
|
||||
如下所示配置即可获取 TDengine Connection：
|
||||
#### 指定URL获取连接
|
||||
|
||||
通过指定URL获取连接，如下所示：
|
||||
|
||||
```java
|
||||
Class.forName("com.taosdata.jdbc.TSDBDriver");
|
||||
String jdbcUrl = "jdbc:TAOS://127.0.0.1:6030/log?user=root&password=taosdata";
|
||||
Class.forName("com.taosdata.jdbc.rs.RestfulDriver");
|
||||
String jdbcUrl = "jdbc:TAOS-RS://taosdemo.com:6041/test?user=root&password=taosdata";
|
||||
Connection conn = DriverManager.getConnection(jdbcUrl);
|
||||
```
|
||||
> 端口 6030 为默认连接端口，JDBC URL 中的 log 为系统本身的监控数据库。
|
||||
|
||||
以上示例，使用 **JDBC-RESTful** 的 driver，建立了到 hostname 为 taosdemo.com，端口为 6041，数据库名为 test 的连接。这个 URL 中指定用户名（user）为 root，密码（password）为 taosdata。
|
||||
|
||||
使用 JDBC-RESTful 接口，不需要依赖本地函数库。与 JDBC-JNI 相比，仅需要：
|
||||
|
||||
1. driverClass 指定为“com.taosdata.jdbc.rs.RestfulDriver”；
|
||||
2. jdbcUrl 以“jdbc:TAOS-RS://”开头；
|
||||
3. 使用 6041 作为连接端口。
|
||||
|
||||
如果希望获得更好的写入和查询性能，Java 应用可以使用 **JDBC-JNI** 的driver，如下所示：
|
||||
|
||||
```java
|
||||
Class.forName("com.taosdata.jdbc.TSDBDriver");
|
||||
String jdbcUrl = "jdbc:TAOS://taosdemo.com:6030/test?user=root&password=taosdata";
|
||||
Connection conn = DriverManager.getConnection(jdbcUrl);
|
||||
```
|
||||
|
||||
以上示例，使用了 JDBC-JNI 的 driver，建立了到 hostname 为 taosdemo.com，端口为 6030（TDengine 的默认端口），数据库名为 test 的连接。这个 URL 中指定用户名（user）为 root，密码（password）为 taosdata。
|
||||
|
||||
**注意**：使用 JDBC-JNI 的 driver，taos-jdbcdriver 驱动包时需要依赖系统对应的本地函数库。
|
||||
|
||||
* libtaos.so
|
||||
在 linux 系统中成功安装 TDengine 后，依赖的本地函数库 libtaos.so 文件会被自动拷贝至 /usr/lib/libtaos.so，该目录包含在 Linux 自动扫描路径上，无需单独指定。
|
||||
|
||||
* taos.dll
|
||||
在 windows 系统中安装完客户端之后，驱动包依赖的 taos.dll 文件会自动拷贝到系统默认搜索路径 C:/Windows/System32 下，同样无需要单独指定。
|
||||
|
||||
> 在 windows 环境开发时需要安装 TDengine 对应的 [windows 客户端][14]，Linux 服务器安装完 TDengine 之后默认已安装 client，也可以单独安装 [Linux 客户端][15] 连接远程 TDengine Server。
|
||||
|
||||
JDBC-JNI 的使用请参见[视频教程](https://www.taosdata.com/blog/2020/11/11/1955.html)。
|
||||
|
||||
TDengine 的 JDBC URL 规范格式为：
|
||||
`jdbc:TSDB://{host_ip}:{port}/[database_name]?[user={user}|&password={password}|&charset={charset}|&cfgdir={config_dir}|&locale={locale}|&timezone={timezone}]`
|
||||
|
||||
其中，`{}` 中的内容必须，`[]` 中为可选。配置参数说明如下：
|
||||
`jdbc:[TAOS|TAOS-RS]://[host_name]:[port]/[database_name]?[user={user}|&password={password}|&charset={charset}|&cfgdir={config_dir}|&locale={locale}|&timezone={timezone}]`
|
||||
|
||||
url中的配置参数如下：
|
||||
* user：登录 TDengine 用户名，默认值 root。
|
||||
* password：用户登录密码，默认值 taosdata。
|
||||
* charset：客户端使用的字符集，默认值为系统字符集。
|
||||
* cfgdir：客户端配置文件目录路径，Linux OS 上默认值 /etc/taos ，Windows OS 上默认值 C:/TDengine/cfg。
|
||||
* charset：客户端使用的字符集，默认值为系统字符集。
|
||||
* locale：客户端语言环境，默认值系统当前 locale。
|
||||
* timezone：客户端使用的时区，默认值为系统当前时区。
|
||||
|
||||
以上参数可以在 3 处配置，`优先级由高到低`分别如下：
|
||||
1. JDBC URL 参数
|
||||
如上所述，可以在 JDBC URL 的参数中指定。
|
||||
2. java.sql.DriverManager.getConnection(String jdbcUrl, Properties connProps)
|
||||
|
||||
|
||||
#### 指定URL和Properties获取连接
|
||||
|
||||
除了通过指定的 URL 获取连接，还可以使用 Properties 指定建立连接时的参数，如下所示：
|
||||
```java
|
||||
public Connection getConn() throws Exception{
|
||||
Class.forName("com.taosdata.jdbc.TSDBDriver");
|
||||
String jdbcUrl = "jdbc:TAOS://127.0.0.1:0/log?user=root&password=taosdata";
|
||||
// Class.forName("com.taosdata.jdbc.rs.RestfulDriver");
|
||||
String jdbcUrl = "jdbc:TAOS://taosdemo.com:6030/test?user=root&password=taosdata";
|
||||
// String jdbcUrl = "jdbc:TAOS-RS://taosdemo.com:6041/test?user=root&password=taosdata";
|
||||
Properties connProps = new Properties();
|
||||
connProps.setProperty(TSDBDriver.PROPERTY_KEY_USER, "root");

3. 客户端配置文件 taos.cfg
|
||||
以上示例，建立一个到 hostname 为 taosdemo.com，端口为 6030，数据库名为 test 的连接。注释为使用 JDBC-RESTful 时的方法。这个连接在 url 中指定了用户名(user)为 root，密码（password）为 taosdata，并在 connProps 中指定了使用的字符集、语言环境、时区等信息。
|
||||
|
||||
linux 系统默认配置文件为 /var/lib/taos/taos.cfg，windows 系统默认配置文件路径为 C:\TDengine\cfg\taos.cfg。
|
||||
```properties
|
||||
# client default username
|
||||
# defaultUser root
|
||||
properties 中的配置参数如下：
|
||||
* TSDBDriver.PROPERTY_KEY_USER：登录 TDengine 用户名，默认值 root。
|
||||
* TSDBDriver.PROPERTY_KEY_PASSWORD：用户登录密码，默认值 taosdata。
|
||||
* TSDBDriver.PROPERTY_KEY_CONFIG_DIR：客户端配置文件目录路径，Linux OS 上默认值 /etc/taos ，Windows OS 上默认值 C:/TDengine/cfg。
|
||||
* TSDBDriver.PROPERTY_KEY_CHARSET：客户端使用的字符集，默认值为系统字符集。

# defaultPass taosdata
|
||||
|
||||
|
||||
#### 使用客户端配置文件建立连接
|
||||
|
||||
当使用 JDBC-JNI 连接 TDengine 集群时，可以使用客户端配置文件，在客户端配置文件中指定集群的 firstEp、secondEp参数。
|
||||
如下所示：
|
||||
|
||||
1. 在 Java 应用中不指定 hostname 和 port
|
||||
|
||||
```java
|
||||
public Connection getConn() throws Exception{

||||
Properties connProps = new Properties();
|
||||
connProps.setProperty(TSDBDriver.PROPERTY_KEY_CHARSET, "UTF-8");

2. 在配置文件中指定 firstEp 和 secondEp
|

```
|

# first fully qualified domain name (FQDN) for TDengine system
|
||||
firstEp cluster_node1:6030
|

# second fully qualified domain name (FQDN) for TDengine system, for cluster only
|
||||
secondEp cluster_node2:6030

# system locale
|
||||
# locale en_US.UTF-8
|
||||
```
|
||||
|
||||
以上示例，jdbc 会使用客户端的配置文件，建立到 hostname 为 cluster_node1、端口为 6030、数据库名为 test 的连接。当集群中 firstEp 节点失效时，JDBC 会尝试使用 secondEp 连接集群。
|
||||
TDengine 中，只要保证 firstEp 和 secondEp 中一个节点有效，就可以正常建立到集群的连接。

> 注意：这里的配置文件指的是调用 JDBC Connector 的应用程序所在机器上的配置文件，Linux OS 上默认值 /etc/taos/taos.cfg ，Windows OS 上默认值 C://TDengine/cfg/taos.cfg。
|
||||
|
||||
#### 配置参数的优先级
|
||||
|
||||
通过以上 3 种方式获取连接，如果配置参数在 url、Properties、客户端配置文件中有重复，则参数的`优先级由高到低`分别如下：
|
||||
1. JDBC URL 参数，如上所述，可以在 JDBC URL 的参数中指定。
|
||||
2. Properties connProps
|
||||
3. 客户端配置文件 taos.cfg
|
||||
|
||||
例如：在 url 中指定了 password 为 taosdata，在 Properties 中指定了 password 为 taosdemo，那么，JDBC 会使用 url 中的 password 建立连接。

在报错后，通过SQLException可以获取到错误的信息和错误码：
|
||||
|
||||
```java
|
||||
try (Statement statement = connection.createStatement()) {
|
||||
// executeQuery
|
||||
ResultSet resultSet = statement.executeQuery(sql);
|

// print result
|
||||
printResult(resultSet);
|
||||
} catch (SQLException e) {
|
||||
System.out.println("ERROR Message: " + e.getMessage());
|
||||
System.out.println("ERROR Code: " + e.getErrorCode());
|
||||
e.printStackTrace();
|
||||
}
|
||||
```
|
||||
|
||||
JDBC连接器可能报错的错误码包括3种：JDBC driver本身的报错（错误码在0x2301到0x2350之间），JNI方法的报错（错误码在0x2351到0x2400之间），TDengine其他功能模块的报错。
|
||||

### <a class="anchor" id="stmt-java"></a>通过参数绑定写入数据
|
||||
|
||||
从 2.1.2.0 版本开始，TDengine 的 **JDBC-JNI** 实现大幅改进了参数绑定方式对数据写入（INSERT）场景的支持。采用这种方式写入数据时，能避免 SQL 语法解析的资源消耗，从而在很多情况下显著提升写入性能。（注意：**JDBC-RESTful** 实现并不提供参数绑定这种使用方式。）
|
||||
|
||||
```java
|
||||
Statement stmt = conn.createStatement();
|
||||
Random r = new Random();
|
||||
|
||||
// INSERT 语句中，VALUES 部分允许指定具体的数据列；如果采取自动建表，则 TAGS 部分需要设定全部 TAGS 列的参数值：
|
||||
TSDBPreparedStatement s = (TSDBPreparedStatement) conn.prepareStatement("insert into ? using weather_test tags (?, ?) (ts, c1, c2) values(?, ?, ?)");
|
||||
|
||||
// 设定数据表名：
|
||||
s.setTableName("w1");
|
||||
// 设定 TAGS 取值：
|
||||
s.setTagInt(0, r.nextInt(10));
|
||||
s.setTagString(1, "Beijing");
|
||||
|
||||
int numOfRows = 10;
|
||||
|
||||
// VALUES 部分以逐列的方式进行设置：
|
||||
ArrayList<Long> ts = new ArrayList<>();
|
||||
for (int i = 0; i < numOfRows; i++){
|
||||
ts.add(System.currentTimeMillis() + i);
|
||||
}
|
||||
s.setTimestamp(0, ts);
|
||||
|
||||
ArrayList<Integer> s1 = new ArrayList<>();
|
||||
for (int i = 0; i < numOfRows; i++){
|
||||
s1.add(r.nextInt(100));
|
||||
}
|
||||
s.setInt(1, s1);
|
||||
|
||||
ArrayList<String> s2 = new ArrayList<>();
|
||||
for (int i = 0; i < numOfRows; i++){
|
||||
s2.add("test" + r.nextInt(100));
|
||||
}
|
||||
s.setString(2, s2, 10);
|
||||
|
||||
// AddBatch 之后，缓存并未清空。为避免混乱，并不推荐在 ExecuteBatch 之前再次绑定新一批的数据：
|
||||
s.columnDataAddBatch();
|
||||
// 执行绑定数据后的语句：
|
||||
s.columnDataExecuteBatch();
|
||||
// 执行语句后清空缓存。在清空之后，可以复用当前的对象，绑定新的一批数据（可以是新表名、新 TAGS 值、新 VALUES 值）：
|
||||
s.columnDataClearBatch();
|
||||
// 执行完毕，释放资源：
|
||||
s.columnDataCloseBatch();
|
||||
```
|
||||
|
||||
用于设定 TAGS 取值的方法总共有：
|
||||
```java
|
||||
public void setTagNull(int index, int type)
|
||||
public void setTagBoolean(int index, boolean value)
|
||||
public void setTagInt(int index, int value)
|
||||
public void setTagByte(int index, byte value)
|
||||
public void setTagShort(int index, short value)
|

public void setTagLong(int index, long value)
|
||||
public void setTagTimestamp(int index, long value)
|
||||
public void setTagFloat(int index, float value)
|
||||
public void setTagDouble(int index, double value)
|
||||
public void setTagString(int index, String value)
|
||||
public void setTagNString(int index, String value)
|
||||
```
|
||||
|
||||
用于设定 VALUES 数据列的取值的方法总共有：
|
||||
```java
|
||||
public void setInt(int columnIndex, ArrayList<Integer> list) throws SQLException
|
||||
public void setFloat(int columnIndex, ArrayList<Float> list) throws SQLException
|
||||
public void setTimestamp(int columnIndex, ArrayList<Long> list) throws SQLException
|
||||
public void setLong(int columnIndex, ArrayList<Long> list) throws SQLException
|
||||
public void setDouble(int columnIndex, ArrayList<Double> list) throws SQLException
|
||||
public void setBoolean(int columnIndex, ArrayList<Boolean> list) throws SQLException
|
||||
public void setByte(int columnIndex, ArrayList<Byte> list) throws SQLException
|
||||
public void setShort(int columnIndex, ArrayList<Short> list) throws SQLException
|
||||
public void setString(int columnIndex, ArrayList<String> list, int size) throws SQLException
|
||||
public void setNString(int columnIndex, ArrayList<String> list, int size) throws SQLException
|
||||
```
|
||||
其中 setString 和 setNString 都要求用户在 size 参数里声明表定义中对应列的列宽。

### <a class="anchor" id="subscribe"></a>订阅
|
||||
|
||||
#### 创建
|
||||
|
||||
```java
|
||||
TSDBSubscribe sub = ((TSDBConnection)conn).subscribe("topic", "select * from meters", false);
|
||||
```
|
||||
|
||||
`subscribe` 方法的三个参数含义如下：
|
||||
|
||||
* topic：订阅的主题（即名称），此参数是订阅的唯一标识
|
||||
* sql：订阅的查询语句，此语句只能是 `select` 语句，只应查询原始数据，只能按时间正序查询数据
|
||||
* restart：如果订阅已经存在，是重新开始，还是继续之前的订阅
|
||||
|
||||
如上面的例子将使用 SQL 语句 `select * from meters` 创建一个名为 `topic` 的订阅，如果这个订阅已经存在，将继续之前的查询进度，而不是从头开始消费所有的数据。
|
||||
|
||||
#### 消费数据
|
||||
|
||||
```java
|
||||
int total = 0;
|
||||
while(true) {
|
||||
TSDBResultSet rs = sub.consume();
|
||||
int count = 0;
|
||||
while(rs.next()) {
|
||||
count++;
|
||||
}
|
||||
total += count;
|
||||
System.out.printf("%d rows consumed, total %d\n", count, total);
|
||||
Thread.sleep(1000);
|
||||
}
|
||||
```
|
||||
|
||||
`consume` 方法返回一个结果集，其中包含从上次 `consume` 到目前为止的所有新数据。请务必按需选择合理的调用 `consume` 的频率（如例子中的 `Thread.sleep(1000)`），否则会给服务端造成不必要的压力。
|
||||
|
||||
#### 关闭订阅
|
||||
|
||||
```java
|
||||
sub.close(true);
|
||||
```
|
||||
|
||||
`close` 方法关闭一个订阅。如果其参数为 `true` 表示保留订阅进度信息，后续可以创建同名订阅继续消费数据；如为 `false` 则不保留订阅进度。
