java.io.StreamCorruptedException:无效的流头:EFBFBDEF [英] java.io.StreamCorruptedException: invalid stream header: EFBFBDEF

问题描述

我正在开发一个Java Web应用程序，在这里我正在使用像项目管理工具之类的Maven，现在我对这个问题感到疯狂. 我尝试从我的应用程序构建一个jasper报告，该报告由我在src/main/resources中拥有的许多子报告组成. 我尝试通过以下方式加载这些子报表:

I'm developing an java web application, where I'm using maven like tool of project managmentand now I'm becaming crazy with this problem. I try to build an jasper report from my application, this report is composed from many sub-report that i have in the src/main/resources. I try to load these subreports in the following way:

//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)上的调用会生成以下异常:

the problem is that the call at this method JRLoader.loadObject(fileSubRep1) generates the following exception:

我在哪里做错了? 我该如何解决?

Where am I doing wrong? How can I to fix it?

推荐答案

最后3天头痛后，我解决了自己的麻烦.我正在使用像项目管理工具这样的maven，并且正在使用这种结构进行模块化项目

Finally after 3 day of headache I solved my trouble. I'm using maven like tool of project managment and I'm working on a modular project with this structure

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

问题在于，我尝试加载的文件(如Input stream)位于services模块的src/main/resources中，但是在Web应用的pom.xml中，我启用了资源过滤功能，并且由于该Web-应用模块取决于服务，过滤已在服务模块上扩展.

The porblem was that the file that I try to load like Input stream was in the src/main/resources in the services module, but in the web-app's pom.xml I enable the resource filtering, and since that web-app module depends of service the filtering was extended at the services module.

在Maven网站的过滤"部分过滤我发现:

In filtering section of the maven web site Filtering I found:

警告:请勿过滤图像等二进制内容的文件！这很可能会导致输出损坏.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.第一个资源集定义了要过滤的文件，另一个资源集定义了要原样复制的文件，如下所示:

Warning: Do not filter files with binary content like images! This will most likely result in corrupt output. If you have both text files and binary files as resources, you need to declare two mutually exclusive resource sets. The first resource set defines the files to be filtered and the other resource set defines the files to copy unaltered as illustrated below:

然后我从网络应用程序模块中删除了以下代码，一切正常

Then I removed the following code from my web-app module and everything works

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