我在一个Oracle WITHSELECT结构上得到一个异常，如果我把它粘贴到SQL Developer中，它可以正常工作，并在9.655s中返回。

我在Java 1.8 JRE上使用Tomcat 9，MyBatis和Oracle 11g（我想）。 Oracle数据库不在我的机器上，但在同一个时区，延迟不是问题。 如果我采用上面的查询，将 "2020Q4 "的?替换为 "2020Q4"，根据SQL Developer的说法，我可以在10秒内得到答案。
一些关键的Maven依赖包括。
<dependency>
<groupId>com.cisco.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.3</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.2</version>
</dependency>
当我得到DataSource来建立连接时，我是这样做的。
OracleDataSource result = new OracleDataSource();
Class.forName("oracle.jdbc.driver.OracleDriver");
String connectionString = lCiscoLifeJdbcUrl;
String username = lCiscoLifeJdbcUserName;
String password = lCiscoLifeJdbcPassword;
OracleDataSource oracleDataSource = (OracleDataSource)result;
oracleDataSource.setURL(connectionString);
oracleDataSource.setPassword(password);
oracleDataSource.setUser(username);
String timeoutKey = "oracle.jdbc.ReadTimeout";
Properties connectionProperties;
try {
connectionProperties = oracleDataSource.getConnectionProperties();
if(connectionProperties==null) {
connectionProperties = new Properties();
}
connectionProperties.put(timeoutKey, 60 /* minutes */ * 60 /* seconds per minutes */ * 1000 /* ms per seconds */);
} catch (SQLException e) {
e.printStackTrace();
}
从之前的调试来看，connectionProperties默认为null，但我想允许比我更聪明的人设置这些属性。
另外，请注意，这个错误发生在64个测试中的8个左右，所以不是每个选择都会触发这个问题。 我没有做数据库更新或DML类型的语句。 在这一点上，一切都被假定为完全提交。
我使用的是MyBatis XML映射器文件，但这是 不 一个Spring驱动的项目。 我通过Java对象手动构建DataSource、Configuration、Environment。
我缺少了什么？
答案
能否设置连接属性，如图所示 DataSourceSample 另外，请查看 OracleConnection 的属性列表。
