java - 处理程序调度失败；嵌套异常是 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 仍保留在 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，这也符合我的环境。

pom.xml 中更新的 Jasper Maven 依赖项如下。

<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，当我尝试运行客户的报告时遇到异常。

Answer 1

该错误表明您的项目中有旧的 DOM/SAX 实现。

您可能对 Xerces 等解析器有直接或传递依赖。

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