网上写的大部分是手动导入，我试过都没用（可能是我没弄懂吧），找了好久终于找到一个大佬写的pom自动导入代码，但是忘记收藏了。。。现在找不到了，于是就写了这篇，希望可以帮到大家。

自动导入简单轻松就解决了问题。


在pom.xml中加入：

<dependency>
			<groupId>javax.el</groupId>
			<artifactId>javax.el-api</artifactId>
			<version>2.2.4</version>
		</dependency>

		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-validator</artifactId>
			<version>5.1.3.Final</version>
		</dependency>

如果不行，再看看是不是环境不满足。

附上可用的pom文件，看看有没有缺少的其他依赖。
