情景

使用hibernate bean validator ，生产环境运行项目正常，但使用单元测试时便抛出异常。

错误信息如下

Caused by: javax.validation.ValidationException: HV000183: Unable to initialize ‘javax.el.ExpressionFactory’. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

方案

添加如下依赖：

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