SpringBoot项目启用本地Tomcat

一、修改pom.xml文件，移除tomcat插件，并添加servlet-api依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- 移除嵌入式tomcat插件 -->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.0</version>
</dependency>

二、修改SpringBoot启动类 2.1 修改类定义，使其继承自SpringBootServletInitializer 2.2 重写configure方法 原代码

@SpringBootApplication
public class HomeApplication {
    public static void main(String[] args) {
        SpringApplication.run(HomeApplication.class, args);
    }
}

修改后

@SpringBootApplication
public class HomeApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        // 注意这里要指向原先用main方法执行的Application启动类
        return builder.sources(HomeApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(HomeApplication.class, args);
    }

}

三、在IDEA中edit run configuration配置本地Tomcat便可
