intellij IDEA tomcat 启动时 报错

Posted 2023-04-03

intellij IDEA tomcat 启动时报错
Error running tomcat7: SSL HTTP Connector node not found: set up one in the server.xml

可能是你的tomcat启动了，把tomcat的服务关了就好了。

同时按”Ctrl+alt+del“，启动‘任务管理器’，选择‘进程’选项卡，找到‘javaw.exe’进程，点击‘结束进程’即可。

就是intellj启动web应用程序的时候会自动启动tomcat，如果你tomcat已经启动，intellj就认为你的8080端口被占用。

IDEA 全称IntelliJ IDEA，是java语言开发的集成环境，IntelliJ在业界被公认为最好的java开发工具之一，也是AES算法标准的主要竞争者，其安全性已经在国际密码年会上被证明。

Tomcat 服务器是一个免费的开放源代码的Web 应用服务器，是Apache 软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun 和其他一些公司及个人共同开发而成。由于有了Sun 的参与和支持，最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现，Tomcat 5 支持最新的Servlet 2.4 和JSP 2.0 规范。

因为Tomcat 技术先进、性能稳定，而且免费，因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可，成为目前比较流行的Web 应用服务器。目前最新版本是8.0。

参考技术A 我也遇到过，哈哈～一定是你的tomcat启动了，把tomcat的服务关了再试试就好了。呵呵～就是intellj启动web应用程序的时候会自动启动tomcat，如果你tomcat已经启动，intellj就认为你的8080端口被占用。本回答被提问者采纳 参考技术B 把配置tomcat的HTTP端口下面的HTTPs的端口去掉就可以了

Spring Boot 嵌入式 Tomcat 服务器未在 intellij idea 中启动

【中文标题】Spring Boot 嵌入式 Tomcat 服务器未在 intellij idea 中启动

【英文标题】：Spring Boot embedded Tomcat server not starting in intellij idea

【发布时间】：2021-07-18 20:58:47

【问题描述】：

我在使用 Spring 初始化程序运行我新创建的 Spring Boot 应用程序时遇到问题。 嵌入式 tomcat 启动失败，出现以下错误

org.springframework.context.ApplicationContextException: 失败 启动 bean 'webServerStartStop';嵌套异常是 org.springframework.boot.web.server.WebServerException：无法 启动嵌入式 Tomcat 服务器

以下是运行应用程序时的完整异常堆栈跟踪消息

【问题讨论】：

如果您不需要它们，我会尝试删除 tomcat-jasper 和 jakarta.servlet.jsp-api

【参考方案1】：

Tomcat 10 附带的 JSP 版本不与嵌入式 Tomcat 9 兼容：Tomcat 9 是 Servlet 4.0 servlet 容器，而 Tomcat 10 是 Servlet 5.0 servlet 容器（参见 @@ 987654321@).

因此，您应该使用与您的 Tomcat 版本兼容的 Jasper 版本。由于spring-boot-starter-parent管理Tomcat依赖的版本，所以删除<version>属性即可：

        <dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
        </dependency>

并删除 jakarta.servlet.jsp-api 依赖项。

编辑：还要注意tomcat-embed-jasper 的范围应该是provided，所以Spring Boot 不会将它打包到WEB-INF/lib 中（而是将它放入WEB-INF/lib-provided）并且你如果将项目部署到外部 Tomcat，将不会遇到版本冲突。

您可以在 spring-boot-dependencies POM 中找到 Spring Boot 为其管理版本的工件列表。

【参考方案2】：

如果你想在spring boot中使用embedded tomcat，你必须将你的依赖库tomcat-jasper改为tomcat-embed-jasper。

spring-boot-starter-web 中有 spring-boot-starter-tomcat。你可以看到here。

spring-boot-starter-tomcat中有tomcat-embed-core可以使用embedded tomcat。你可以看到here。

embed-jaspser 包括与tomcat-embed-core 的依赖关系。你可以看到here。

您使用的tomcat-jasper 是不必要的，因为它不包含依赖关系tomcat-embed-core。你可以看到here。

【讨论】：

我同意应该使用tomcat-embed-jasper 而不是tomcat-jasper：这些罐子有95% 相似，但是tomcat-embed-jasper 依赖于tomcat-embed-core（已经包含在spring-boot-starter 中）所以Maven 项目不会拉取无用的tomcat-catalina 和tomcat-util 依赖项。
