我有一种用jett生成报告的方法:
try {
InputStream inPath = ProdutoManagedBean.class.getResourceAsStream("/template.xls");
ExcelTransformer transformer = new ExcelTransformer();
transformer.transform(inPath, beans);
} catch (IOException e) {
e.printStackTrace();
} catch (InvalidFormatException e) {
e.printStackTrace();
}
我在transformer.transfom(...)中遇到InvalidFormatException:
22:44:37,803 ERROR [stderr] (default task-28) org.apache.poi.openxml4j.exceptions.InvalidFormatException: Your InputStream was neither an OLE2 stream, nor an OOXML stream
我调查了maven导致这个数据损坏,但我把过滤器工件放在pom.xml中,它仍然继续损坏:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>${compiler-plugin.version}</version>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.5</version>
<inherited>true</inherited>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
<plugin>
答案 0 :(得分:0)
我能够解决;我将此工件放在具有Web基础结构组件的项目的pom.xml中:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.1.0</version>
<inherited>true</inherited>
<configuration>
<encoding>UTF-8</encoding>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>xls</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</plugin>
</plugins>
</build>
这可能是由项目技术架构的特殊性引起的问题。
