我尝试在报告中使用 groovy 将子数据集连接到 Oracle 数据库。

-> 在报告中> 属性> 语言：groovy

-> 在我的数据集中，我选择“使用其他连接”和表达式：

Sql.newInstance(
                    "jdbc:oracle:thin:@ip:1521:XE",
                    "user",
                    "pw",
                    "oracle.jdbc.driver.OracleDriver"
                )

我的参数（ip、端口、用户、密码）是正确的，我已经做了这个 java 并且它可以工作，但我需要用 groovy 来做这个:(

当我预览报告（使用 groovy）时，我收到以下错误：

net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :
    Source text : Sql.newInstance(

                    "pw",

                    "oracle.jdbc.driver.OracleDriver"

首先，感谢您的回复。

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", "oracle.jdbc.driver.OracleDriver")

似乎是一个很好的表达方式：当我尝试使用 groovyconsole.bat 连接到我的数据库时它可以工作。

但是我总是无法从 jasperstudio 连接到我的 oracle 数据库，我不知道为什么。

我有 ojdbc14-1.0.jar 到我的构建路径（我使用与 java jdbc 连接相同的 jar，它正在工作）

我有 groovy-sql-2.3.6.jar 到我的构建路径（然后所有来自 groovy 的 .jar 因为我“绝望”但它没有改变任何东西）

-> 在报告中> 属性> 语言：groovy

-> 在我的数据集中，我选择“使用其他连接”和表达式：

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", "oracle.jdbc.driver.OracleDriver")

它仍然不起作用我在预览后的“填写报告”阶段收到以下错误：

我也尝试使用“/XE”，但它也不起作用。

我不知道我做错了什么，有什么想法吗？

感谢帮助 ！:)

替换这个：

Sql.newInstance(
                "jdbc:oracle:thin:@ip:1521:XE",
                "user",
                "pw",
                "oracle.jdbc.driver.OracleDriver"
               )

有了这个：

groovy.sql.Sql.newInstance("jdbc:oracle:thin:@ip:1521:XE", "user", "pw", 
        "oracle.jdbc.driver.OracleDriver")
