JasperReports：未找到CONCATENATE函数 [英] JasperReports: CONCATENATE function not found

问题描述

我正在使用 Jaspersoft Studio 开发一些报告。

我有一个应用程序接受REST查询，并将它们转换为编译报告。


所以我有一些 JasperReports 包括：

• groovy-all-2.0.1 .jar
  
• iText-2.1.7.js2.jar


• jasperreports-5.2.0.jar

ul>



问题是，当我编译我的报告并从 Jaspersoft Studio 运行时，它工作正常。

但是当我编译并运行它从我的web应用程序，它会引发异常：

  net.sf.jasperreports.engine.fill.JRExpressionEvalException：评估表达式时出错：
源文本：CONCATENATE（$ V {startString}， - ，$ V {endString}）
 at net.sf.jasperreports.engine.fill.JREvaluator.evaluate（JREvaluator。 java：244）
 at net.sf.jasperreports.engine.fill.JRCalculator.evaluate（JRCalculator.java:591）
 at net.sf.jasperreports.engine.fill.JRCalculator.e评估（JRCalculator.java:559）
 ... 
引起：net.sf.jasperreports.engine.JRRuntimeException：找不到函数CONCATENATE 
  

当我在报告中更改我的 CONCATENATE 调用时，它可以正常工作。





所以这给我留下了一个解决方案，我错过了一个 JasperReports 罐子，但是哪一个？

解决方案

您还应该将 jasperreports-functions-5.2.0.jar 添加到您的类路径中。





库包含 net.sf.jasperreports.functions.standard.TextFunctions 类与 CONCATENATE 函数。





你可以找到此工件位于 http://jaspersoft.artifactoryonline.com/jaspersoft/jr-ce-releases Maven 存储库。





我的测试代码 pom.xml ：

net.sf.jasperreports.jasperreports-functions：5.2.0 工件取决于 joda-time.joda-time：2.1 工件 - 您还应该向类路径添加 joda-time-2.1.jar

I'm developing some reports with Jaspersoft Studio.
I have a web app that should accept REST queries, and turn them into compiled reports.
So I have some of the JasperReports jars included:

• groovy-all-2.0.1.jar
• iText-2.1.7.js2.jar
• jasperreports-5.2.0.jar

Problem is that when I compile my report and run from the Jaspersoft Studio, it works fine.
But when I compile and run it from my web app, it throws the exception:

net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : 
    Source text : CONCATENATE($V{startString}, "  -  ", $V{endString})
    at net.sf.jasperreports.engine.fill.JREvaluator.evaluate(JREvaluator.java:244)
    at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:591)
    at net.sf.jasperreports.engine.fill.JRCalculator.evaluate(JRCalculator.java:559)
...
Caused by: net.sf.jasperreports.engine.JRRuntimeException: Function CONCATENATE not found

When I change my CONCATENATE call in the report it works fine.

So this leaves me with a solution that I'm missing one of the JasperReports jars, but which one?

解决方案

You should also add jasperreports-functions-5.2.0.jar to your classpath.

This library contains net.sf.jasperreports.functions.standard.TextFunctions class with CONCATENATE function.

You can find this artifact at http://jaspersoft.artifactoryonline.com/jaspersoft/jr-ce-releases Maven repository.

The snippet from my test pom.xml:

<repositories>
    <repository>
        <id>jr-ce-releases</id>
        <url>http://jaspersoft.artifactoryonline.com/jaspersoft/jr-ce-releases</url>
    </repository>
</repositories>

<dependencies>
    <dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>5.2.0</version>
    </dependency>

    <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <version>2.0.1</version>
    </dependency>
    <dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports-functions</artifactId>
        <version>5.2.0</version>
    </dependency>
    <dependency>
        <groupId>joda-time</groupId>
        <artifactId>joda-time</artifactId>
        <version>2.1</version>
    </dependency>
</dependencies>

The net.sf.jasperreports.jasperreports-functions:5.2.0 artifact depends on joda-time.joda-time:2.1 artifact - you should also add to classpath the joda-time-2.1.jar
