仅使用JDBC的Socket读取超时

问题描述 投票：0回答：1

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？

oracle jdbc mybatis ojdbc

能否设置连接属性，如图所示 DataSourceSample 另外，请查看 OracleConnection 的属性列表。
