本篇内容介绍了“idea怎么使用外置tomcat配置springboot”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

创建一个maven项目
导入springboot依赖，注意底下注释部分

<?xmlversion="1.0"encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.znsd.springboot</groupId><artifactId>springboot-jsp</artifactId><version>1.0-SNAPSHOT</version><packaging>war</packaging><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.12.RELEASE</version><relativePath/></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope><exclusions><exclusion><groupId>org.junit.vintage</groupId><artifactId>junit-vintage-engine</artifactId></exclusion></exclusions></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

完成下图操作保存即可

配置tomcat启动项

配置视图解析器

创建一个springboot主程序

@SpringBootApplicationpublicclassSpringBootMain{publicstaticvoidmain(String[]args){SpringApplication.run(SpringBootMain.class,args);}}

必须编写一个SpringBootServletInitializer的子类，并调用configure方法里面的固定写法

publicclassServletInitializerextendsSpringBootServletInitializer{@OverrideprotectedSpringApplicationBuilderconfigure(SpringApplicationBuilderapplication){//传入SpringBoot的主程序，returnapplication.sources(SpringBootMain.class);}}

然后启动tomcat，控制台输出了spring就启动成功了
