java.io.StreamCorruptedException： invalid stream header： EFBFBDEF

java maven jasper-reports subreport
2022-09-02 23:06:51

我正在开发一个java Web应用程序，我正在使用像项目管理工具一样的maven，现在我对这个问题感到疯狂。我尝试从我的应用程序中构建一个jasper报告，此报告由我在src/main/resources中的许多子报告组成。我尝试按以下方式加载这些子报表：

//Sub Report 1 
InputStream fileSubRep1=(BufferedInputStream) getClass().getResourceAsStream("/fileSubReport1.jasper");
map.put("fileSubRep1",(JasperReport) JRLoader.loadObject(fileSubRep1));

//Sub Report 2 
InputStream fileSubRep2=(BufferedInputStream) getClass().getResourceAsStream("/fileSubReport2.jasper");
map.put("fileSubRep1",(JasperReport) JRLoader.loadObject(fileSubRep2));

问题是在此方法 JRLoader.loadObject（fileSubRep1） 处的调用会生成以下异常：

我哪里做错了？我该如何修复它？


答案 1

终于在头痛3天后，我解决了我的麻烦。我正在使用类似maven的项目管理工具，并且我正在使用这种结构进行模块化项目

|-- parent
   |-- model
    --pom.xml
   |-- services
    --pom.xml
   |-- web-app
    --pom.xml

问题是，我尝试加载的文件（如输入流）位于服务模块的 src/main/resources 中，但在 web 应用的 pom 中.xml我启用了资源筛选，并且由于该 Web 应用模块依赖于服务，因此在服务模块上扩展了筛选。

在 maven 网站的过滤部分 过滤 我发现：

警告：不要过滤带有图像等二进制内容的文件！这很可能导致输出损坏。如果同时具有文本文件和二进制文件作为资源，则需要声明两个互斥的资源集。第一个资源集定义要筛选的文件，另一个资源集定义要原封不动地复制的文件，如下图所示：

然后我从我的Web应用程序模块中删除了以下代码，一切正常

<resources>
     <resource>
         <directory>src/main/resources</directory>
         <filtering>true</filtering>
    </resource>
</resources>

答案 2

感谢您的解决方案@skizzo

一种不那么激烈的方法，如果你仍然需要过滤一些其他文件，或者复制所有文件，只是简单地包括你需要过滤的所有文件（java，xml，属性...）。

这是我刚刚实施的解决方案，感谢您的帮助：

        <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.java</include>
                <include>**/*.xml</include>
                <include>**/*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>false</filtering>
            <excludes>
                <exclude>**/*.java</exclude>
                <exclude>**/*.xml</exclude>
                <exclude>**/*.properties</exclude>
            </excludes>
        </resource>
    </resources>

它似乎根本没有关系，我已经找了几个小时了。它真的拯救了我的一天！;-)
