资源代码：

如上
了解资源代码：
写了一个controller代码，控制接口对应该运行的函数。
package org.example.testproducttomcatwar; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloController { @GetMapping("/hello") public String hello() { return "Spring Boot WAR 项目成功运行！"; } }application的代码：
package org.example.testproducttomcatwar; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; @SpringBootApplication public class TestproducttomcatwarApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(TestproducttomcatwarApplication.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(TestproducttomcatwarApplication.class); } }在这段代码中，一定要继承父类并复写configure函数。
为什么要写configure函数？
是为了让导出的war包给tomcat使用的时候可以给tomcat识别到并调用
TestproducttomcatwarApplication.class
依赖pom.xml如下：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>4.0.0</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>org.example</groupId> <artifactId>testproducttomcatwar</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 打包方式修改成 war --> <packaging>war</packaging> <name>testproducttomcatwar</name> <description>testproducttomcatwar</description> <url/> <licenses> <license/> </licenses> <developers> <developer/> </developers> <scm> <connection/> <developerConnection/> <tag/> <url/> </scm> <properties> <java.version>17</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- Web --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- 排除内置 Tomcat --> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <!-- 使用外部容器时提供 Tomcat 运行环境 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>运行操作：
一、
idea运行
资源里的testproducttomcatwar项目，改项目终端运行mvn clean install，
生成war包
二、
将1中的war包粘贴到项目
运行tomcattest项目时需要配置，
配置如下：
添加后
在配置里修改url
运行后，得到效果：
