# IDEA注意事项

关于语言版本不停回溯到默认值问题：

需要在 pom.xml 中指定：

<properties>
    <java.version>1.8</java.version>
</properties>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

代码没有问题但是运行 404、ClassNotFound 或者其他问题：

在 Project Structure 的 Artifacts 中，在 WEB-INF 文件夹中创建 lib 文件夹并添加全部依赖。
配置了 default handler 后静态资源依然 404：检查 out 文件夹。

使用纯 JavaConfig 配置 SSM
