Question

在这个例子中，我正在使用Apache Camel和Apache CXF：

http://camel.apache.org/better-jms-transport-for-cxf-webservice-using-apache-camel.data/cxfcamelexample.zip

我按照自述文件进行了尝试运行客户端＆amp;服务器类我有这个例外：

log4j:ERROR setFile(null,true) call failed.

所以任何想法，如何解决这个异常？

Answer 1

你在root上有/ target目录吗？如果没有，请尝试创建一个。记录器希望能够在该目录中创建一个文件，如果它不存在则存在问题。

Answer 2

如果您正在启动经纪人，则可能会出现此问题。

我在与此问题相关的ActiveMQ错误跟踪网站中发现了错误报告。

Activeio测试包包含和日志记录属性： https://issues.apache.org/jira/browse/AMQ-1132

我排除 org.apache.activemq：activeio-core 以从依赖项中删除 test-jar 并解决了此问题。这对你也有帮助。

Answer 3

嘿，我又遇到了这个问题，我想用我所做的来回答，这正是@lemiorhan的建议。我将通过提供示例代码来改善他的回答。只需在org.apache.activemq依赖项中的标记后面添加此代码即可。

<exclusions>
    <exclusion>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activeio-core</artifactId>
    </exclusion>
</exclusions>

java.io.FileNotFoundException：/target/test.log
