Handler dispatch failed; nested exception is java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V

Question

先决条件

我最近从 JasperReports 版本 3.7.6 升级到 6.4.1。 JasperReports-fonts 保持在 5.6.1 版本。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，这也与我的环境相匹配。

pom.xml中更新的Jasper Maven依赖如下。

<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>

我意识到这是一个很大的版本跳跃，我们一定会遇到一些错误，但是 Maven 构建并编译了 .jrxml 报告文件成功。但是，我在尝试运行来自客户的报告时遇到异常。

该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的版本，或者 remove/exclude 以便使用 JRE 中包含的解析器。
