You can build Java connector from source code after cloning the TDengine project:
```
git clone https://github.com/taosdata/taos-connector-jdbc.git
git clone https://github.com/taosdata/taos-connector-jdbc.git --branch 2.0
cd taos-connector-jdbc
mvn clean install -Dmaven.test.skip=true

1. Do not specify hostname and port in Java applications.
```java
public Connection getConn() throws Exception{

String jdbcUrl = "jdbc:TAOS://:/test?user=root&password=taosdata";
Properties connProps = new Properties();

public Connection getConn() throws Exception{
Class.forName("com.taosdata.jdbc.TSDBDriver");
String jdbcUrl = "jdbc:TAOS://:/test?user=root&password=taosdata";
Properties connProps = new Properties();

connProps.setProperty(TSDBDriver.PROPERTY_KEY_TIME_ZONE, "UTC-8");

2. specify the firstEp and the secondEp in the configuration file taos.cfg
```shell
# first fully qualified domain name (FQDN) for TDengine system
firstEp cluster_node1:6030
```shell
# 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
# second fully qualified domain name (FQDN) for TDengine system, for cluster only
secondEp cluster_node2:6030
# default system charset
# charset UTF-8
# default system charset
# charset UTF-8
# system locale
# locale en_US.UTF-8
```
# system locale
# locale en_US.UTF-8
```
In the above example, JDBC uses the client's configuration file to establish a connection to a hostname `cluster_node1`, port 6030, and a database named `test`. When the firstEp node in the cluster fails, JDBC attempts to connect to the cluster using secondEp.
