Question

我遇到log4j2问题

下面是我的log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Logger name="com.opensymphony.xwork2" level="info"/>
        <Logger name="org.apache.struts2" level="info"/>
        <Root level="info">
            <AppenderRef ref="STDOUT"/>
        </Root>
    </Loggers>
</Configuration>

以下是例外

上述异常导致war文件部署失败。

下面是使用的罐子

1.commons-fileupload-1.3.3.jar
2.commons-io-2.5.jar
3.commons-lang3-3.6.jar
4.commons-logging-1.1.3.jar
5.freemarker-2.3.26-incubating.jar
6.javassist-3.20.0-GA.jar
7.log4j-1.2-api-2.11.0.jar
8.log4j-api-2.10.0.jar
9.log4j-core-2.11.0.jar
10.ognl-3.1.15.jar
11.struts2-core-2.5.16.jar

我需要纠正什么？

Answer 1

尝试将log4j-api-2.10.0.jar升级到2.11.0。

AWS.config = new AWS.Config({ accessKeyId: data.accessKey, secretAccessKey: data.secretAccessKey });从IllegalArgumentException的构造函数中抛出：

org.apache.logging.log4j.util.SortedArrayStringMap

，自2.11开始，给定参数public SortedArrayStringMap(final int initialCapacity) { if (initialCapacity < 1) { throw new IllegalArgumentException("Initial capacity must be at least one but was " + initialCapacity); } threshold = ceilingNextPowerOfTwo(initialCapacity); }已更改，如下所示：

Answer 2

将log4j-api和log4j-core从2.11.1更新到2.12.0对我来说解决了相同的问题。
