Question

我尝试将groovy用于我的报告，以将子数据集连接到Oracle数据库。

- ＆GT;在报告中＆gt;性状＆gt;语言：groovy

- ＆GT;在我的数据集中，我选择“使用其他连接”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）是更正的，我已经做了这个java并且它可以工作但我需要用groovy做这个：（

当我预览报告时（使用groovy），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：当我尝试使用groovyconsole.bat连接到我的数据库时，它会起作用。

但是我总是愿意从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（与java jdbc连接使用的jar相同，它正在工作）

我的groovy-sql-2.3.6.jar到我的构建路径（然后来自groovy的所有.jar因为我“无望”但它没有改变任何东西）

- ＆GT;在报告中＆gt;性状＆gt;语言：groovy

- ＆GT;在我的数据集中，我选择“使用其他连接”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“填充报告”阶段得到以下错误：

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？

感谢您的帮助！：）

替换它：

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

用这个：

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

与Jaspersoft Studio的groovy和jdbc连接
