SpringBoot tomcat

Posted 2020-10-05 lototo

　　该文的前提是已经可以在控制台运行成功，有些时候想放在tomcat里运行 大致分为如下几步

　　1.配置文件更改

　　　　

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId> 
            <!-- <artifactId>spring-boot-starter</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>

　　　　需要移除以前的启动包添加web启动，并移除自带的然后添加如下

　　　　

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

　　然后将 <packaging>jar</packaging>改成 <packaging>war</packaging>

　　将该包放入tomcat下面

　2.添加类SpringBootStartApplication 并继承SpringBootServletInitializer具体类代码如下：

　　

package com.front.springboot;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootStartApplication extends SpringBootServletInitializer {
     @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            
            return builder.sources(SpringBootStartApplication.class);
        }

}

3.启动之后就可以看到已经可以运行了。

这里附带我最后的pom 配置文件
