• javax/servlet/ServletContext : Unsupported major.minor version 51.0


    原文:http://blog.csdn.net/mlin_123/article/details/50738532

    解决:将版本从 3.1.0 改为 3.0.1 

    <!-- 添加servlet API 依赖-->
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.0.1</version>
    </dependency>

    进行 SpringJunit  测试时,报错:
