先决条件

我最近从JasperReports版本 3.7.6 升级到 6.4.1 。 JasperReports-fonts仍为版本 5.6.1 。我还确保更新每个项目的核心依赖项，它们现在包含在Maven构建中。

我的服务器有一个JavaSE-1.8构建路径，这也符合我的环境。

pom.xml中更新的Jasper Maven依赖项如下所示。

<dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports-fonts</artifactId>
        <version>5.6.1</version>
        <type>jar</type>
        <scope>compile</scope>
</dependency>  

<dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>6.4.1</version>
        <type>jar</type>
        <scope>compile</scope>
</dependency>

我意识到这是一个大版本的跳转，我们肯定会遇到一些错误，但Maven构建并编译.jrxml报告文件成功。但是，我尝试从客户端运行报告时遇到异常。

错误表明您的项目中有一个旧的DOM / SAX实现。

您可能对Xerces等解析器具有直接或传递依赖性。

您应该将依赖项升级到较新版本，或者删除/排除它，以便使用JRE中包含的解析器。

处理程序发送失败;嵌套异常是java.lang.AbstractMethodError：javax.xml.parsers.DocumentBuilderFactory.setFeature（Ljava / lang / String; Z）V
