Maven Struts2项目（org.apache.struts：struts2-archetype-starter）在intellij idea 15.0.4中创建了一些问题

Question

我使用maven3（选择org.apache.struts:struts2-archetype-starter）在IntelliJ IDEA 15.0.4（终极版）中创建了Struts2项目。创建此项目后，会出现一些问题，例如下面的屏幕。我想要注意到我为maven启用了自动导入。

这是我的pom.xml：

如何解决此问题？

Answer 1

修改pom.xml并添加

<properties>
    <struts2.version>2.3.24.1</struts2.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>

    <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-core</artifactId>
        <version>${struts2.version}</version>
    </dependency>

编译错误指向项目配置中缺少的依赖项。如果您将Maven与IJ一起使用，则应将Maven配置与IJ配置同步。要让IJ自动执行此操作，您可以选中显示的通知框或使用项目设置。

Answer 2

我已经解决了这个问题。您必须更改pom.xml中标记<version>中的数据。如下图所示。

<!-- Logging -->
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>${log4j2.version}</version>
    </dependency>

到

<!-- Logging --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.5</version> </dependency>
