java.io.StreamCorruptedException:无效的流标题:EFBFBDEF

Question

我正在开发一个java web应用程序,我正在使用maven作为项目管理工具,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,这个报告由我在src/main/resources中的许多子报告组成.我尝试以下列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));

问题是这个方法调用JRLoader.loadObject(fileSubRep1)会产生以下异常:

我哪里做错了？我该怎么解决它？

Answer 1

经过3天的头痛后,我解决了我的麻烦.我正在使用maven作为项目管理工具,我正在开发一个具有这种结构的模块化项目

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

问题是我尝试像Input流一样加载的文件位于services模块的src/main/resources中,但是在web-app的pom.xml中我启用了资源过滤,因为该web-app模块依赖在服务模块中扩展了过滤服务.

在maven网站过滤部分Filtering我发现:

警告:不要使用像图像这样的二进制内容过滤文件!这很可能会导致输出损坏.如果您同时拥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过滤的文件,另一个资源集定义要保持不变的文件,如下所示:

然后我从我的网络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>

Answer 2

我有完全相同的问题，我解决了在 pom.xml 中添加以下插件

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.0.2</version>
            <configuration>
              <nonFilteredFileExtensions>
                <nonFilteredFileExtension>pdf</nonFilteredFileExtension>
                <nonFilteredFileExtension>jasper</nonFilteredFileExtension>
              </nonFilteredFileExtensions>
            </configuration>
          </plugin>

感谢这个解决方案@skizzo

一个不太激烈的方法，如果您仍然需要过滤一些其他文件，或者复制所有文件，只需包含您需要过滤的所有文件（java、xml、属性...）。

由于您的帮助，这是我刚刚实施的解决方案：

        <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，我已经找了好几个小时了。它真的救了我的一天！;-)
