Spring Cloud 注册中心在tomcat中部署

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{    @Override    protected 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

注意事项

还有诸多需要注意的地方暂未发现,随着个人的学习逐渐完善,目前这篇博客只使用与spring cloud 注册中心的初学者,尝试在tomcat上部署项目,注意举一反三
