Tomcat部署Springboot-war包_tomcat部署springboot的war包

Tomcat部署Springboot-war包

第一步：创建springboot项目（这里不赘述）
第二步：剔除springboot内置tomcat，添加外部tomcat依赖以及servlet依赖，将pom的打包方式改为war

  <packaging>war</packaging>

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


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

第三步：启动类继承SpringBootServletInitializer类，重写configure，我这提前写了一个类继承了

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(TestSpringbootTomcatApplication.class);
    }

}

启动类就这么写

@SpringBootApplication
public class TestSpringbootTomcatApplication  extends ServletInitializer{

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

}

第四步：使用maven的打包工具将项目打包
第五步：将项目放到tomcat/webapps/ 下，可以自己新建文件夹 将war包扔进去
第六步：修改tomcat/conf/server.xml

在Host节点里添加
<Context path="项目访问地址" docBase="war包绝对路径" debug="0" reloadable="true" />
第七步：启动tomcat
