前言

最近刚刚接触spring boot 和spring cloud,只知道可以直接通过main方法启动服务,一直不会将项目部署到tomcat中,今天学了一下,做个记录备忘.

步骤

pom文件

在pom文件中引入spring-boot-starter-web,然后排除掉内置的tomcat,最后引入javax.servlet-api,修改package为war,详细如下

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>SpringCloudServer</groupId><artifactId>Spring_Cloud_Server</artifactId><version>1.0-SNAPSHOT</version><name>springcloudserver</name><packaging>war</packaging><!--spring cloud server 使用时需要注意parent的版本号和dependencies的版本号--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.5.6.RELEASE</version><relativePath/></parent><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><!--<version>Brixton.SR5</version>--><version>Dalston.SR2</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><dependencies><!--引入spring boot的web--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><!--排除内置的tomcat--><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId></exclusion></exclusions></dependency><!--引入 servlet api--><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka-server</artifactId></dependency></dependencies></project>

主函数启动类

主函数启动类需要继承SpringBootServletInitializer,重写config方法

import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.web.support.SpringBootServletInitializer;import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;@SpringBootApplication@EnableEurekaServerpublic class ServerApplication_First extends SpringBootServletInitializer{@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {        return builder.sources(ServerApplication_First.class);}    public static void main(String[] args) {        new SpringApplicationBuilder(ServerApplication_First.class).web(true).run(args);}
}

注意:因为把spring boot自带的tomcat排除了,所以无法再使用main主函数启动程序
