hibernate中的Javassist失败:无效的常量类型:60

Question

我正在创建一个cli工具来管理现有的应用程序.应用程序和测试都构建良好并运行良好,但尽管我在运行jar中存在的cli工具时收到了javassist失败:

因为我知道jar是好的,因为单元和集成测试对它运行,我认为它可能是javassist的问题,所以我尝试了cglib.然后字节码提供程序显示为cglib,但我仍然得到完全相同的堆栈跟踪,其中包含javassist.

cglib肯定在类路径中:

$ unzip -l flexipol-jar-with-dependencies.jar | grep cglib | wc -l
383

我已尝试使用hibernate 3.4和3.5并获得完全相同的错误.这是javassist的问题吗？

更新:我可以在Eclipse中成功运行应用程序(右键单击 - >运行As-> Java应用程序),但使用maven生成的jar-with-dependencies失败.我认为不同之处在于Eclipse javassist不检查包含jar,而是检查所有类文件(可能还有一些依赖的第三方jar).

这个问题最终是由一个无效的类引起的,icu4j-2.6.1如本文所示.具体来说,此文件无效:

com/ibm/icu/impl/data/LocaleElements_zh__PINYIN.class

这是识别损坏文件的简单方法:

for x in PATH_TO_EXTRACTED_JAR/**/*.class; do
    java -cp PATH_TO/javassist.jar javassist.tools.Dump $x >/dev/null 2>&1 || echo "$x is invalid"
done

该文件由maven通过其传递依赖性间接包含,这就是为什么我不认识该页面引用错误和jar中包含的文件是问题的罪魁祸首和原因.以下是它最终包含在我的jar-with-dependencies包中的方法:

jaxen-1.1.1 -> xom-1.0 -> icu4j-2.6.1

将以下排除项添加到jaxen依赖项后,一切都正常对我(但如果您需要其本地化部分,请小心):

<exclusions>
    <exclusion>
        <groupId>com.ibm.icu</groupId>
        <artifactId>icu4j</artifactId>
    </exclusion>
</exclusions>

另一个选择是从jar文件中删除有问题的文件:

#!/bin/sh                                                                                                                                                                                                                                    
shopt -s extglob
shopt -s globstar
for x in **/*.jar ; do
    zip -d $x 'com/ibm/icu/impl/data/*_zh*' >/dev/null 2>&1 && echo "Removed corrupted files from $x"
done
