Question

我在OpenJPA日志记录方面遇到了一些问题。正如有人建议的那样，我试图将OpenJPA设置为使用log4j，并在persistence.xml中包含以下行：

<property name="openjpa.Log" value="log4j"/>

但它立即打破了openJPA增强过程：

openJPA_enhance.xml:26: java.lang.NoClassDefFoundError: org/apache/log4j/Priority

更新（Aninda感谢您的帮助）。

在我包含openJpa.jar之后，OpenJPA Enhancer现在无法加载log4j.properties。我在类路径中包含了Log4j属性和一个jvm参数：“ - Dlog4j.configuration”

我无法通过OpenJPA传递异常：

Buildfile: ../Workspaces_JEE/ETM_Workspace/ETM/openJPA_enhance.xml

openjpa.libs.check:

build.dir.check:

enhance:
        [echo] /home/jamad/Workspaces/Workspaces_JEE/ETM/build/classes:/home/jamad/Workspaces/Workspaces_JEE/ETM/src/META-INF/log4j.properties

    [openjpac] log4j:WARN Please initialize the log4j system properly.

OpenJPA使用Log4j制动OpenJPA增强版
