問題

整合Spring MVC由于用到j(luò)stl，所以引入jstl標(biāo)簽用的jar包，啟動tomcat時控制臺出現(xiàn)了如下的輸出：

解決方法

由于standard.jar與jstl.jar需一起使用，但是jstl 1.2版本的就不需要這個standard.jar包了，而本人使用的正是jstl 1.2.jar這個jar包，去掉standard.jar文件后重啟tomcat就不會再出現(xiàn)上述信息。

        <dependency>
            <groupId>taglibs</groupId>
            <artifactId>standard</artifactId>
            <version>1.1.2</version>
        </dependency>
