Tomcat 7 WAR部署-“未加载jar”

时间：2018-12-12 08:05:00

标签： java spring spring-boot tomcat intellij-idea

将WAR部署到我的spring boot应用程序时出现错误。我查看了其他线程，但似乎无法解决该问题。我的WEB-INF /中根本没有jar。我有依赖javax.servlet（但是由于某种原因我只能访问2.5版，intellij为我提供了所有更高版本的“找不到资源”）。我怀疑这可能是问题所在，但我不知道如何解决。

Tomcat会忽略您的servlet-api-2.5.jar，因为tomcat已经具有该jar的内置版本，因此不会使用您的。因此，只需在pom.xml中添加以下内容即可构建您的项目：

<dependency>
    ...
    <exclusions>
      <exclusion>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-servlet</artifactId>
      </exclusion>
    </exclusions> 
</dependency>
