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

Question

在此示例中，我问候所有使用Apache Camel和Apache CXF的人：

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

我遵循自述文件，并尝试运行客户端和服务器类我有这个例外：

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

所以有什么主意，如何解决这个异常？

Answer 1

您在根目录下是否有/ target目录？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文件，如果不存在，则存在问题。

Answer 2

如果您正在启动代理，则可能出现该问题。

我在ActiveMQ错误跟踪网站中发现了与此问题相关的错误报告。

Activeio测试包的包含和记录属性：https://issues.apache.org/jira/browse/AMQ-1132

我排除了org.apache.activemq：activeio-core以从依赖项中删除test-jar，并解决了此问题。这也可能对您有帮助。

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>
