ireport做的报表编译为jasper文件，maven package成war后部署过去，访问产生错误：

 

net.sf.jasperreports.engine.JRException: Error loading object from InputStream
...
java.io.StreamCorruptedException: invalid stream header: EFBFBDEF
    java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:782)
    java.io.ObjectInputStream.(ObjectInputStream.java:279)
    net.sf.jasperreports.engine.util.ContextClassLoaderObjectInputStream.(ContextClassLoaderObjectInputStream.java:53)
    net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:214)

 

发现war里面的jasper文件的大小与工程里的不一致，经过一通google，发现是maven的资源文件过滤的问题，有的更深入的说是编码改变为UTF-8了

 

解决：在pom的build节点添加maven-resources-plugin插件，让maven打包的时候不过滤jasper文件

 

<plugins>
	<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-resources-plugin</artifactId>
		<version>2.5</version>
		<configuration>
			<nonFilteredFileExtensions>
				<nonFilteredFileExtension>jasper</nonFilteredFileExtension>
			</nonFilteredFileExtensions>
		</configuration>
	</plugin>
</plugins>
