groovy和jdbc与Jaspersoft Studio的连接

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>属性>语言中：groovy

->在我的数据集中，我选择“使用其他连接”并使用以下表达式：

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

groovy.sql.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，它可以工作，但我需要用groovy来做：(

当我预览报告（使用groovy）时，会出现以下错误：

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

首先，感谢您的回复

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

这似乎是一个很好的表达式：当我尝试使用groovyconsole.bat连接到数据库时，它会起作用

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

我的构建路径中有ojdbc14-1.0.jar（与JavaJDBC连接中使用的jar相同，它正在工作）

我的构建路径中有groovy-sql-2.3.6.jar（然后是groovy中的all.jar，因为我“没有希望”，但它没有改变任何东西）

->在报告>属性>语言中：groovy

->在我的数据集中，我选择“使用其他连接”并使用以下表达式：

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

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”阶段出现以下错误：

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

谢谢您的帮助！：）

更换此：

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

为此：

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

---

也许您需要导入

Sql

class-

导入groovy.Sql.Sql

？谢谢！我很糟糕，多亏了你，我有了解决方案：groovy.sql.sql.newInstance（“jdbc:oracle:thin:@ip:1521:XE”、“user”、“pw”、“oracle.jdbc.driver.OracleDriver”）
