Spring Cloud 註冊中心在tomcat中部署

前言

最近剛剛接觸spring boot 和spring cloud,只知道能夠直接經過main方法啓動服務,一直不會將項目部署到tomcat中,今天學了一下,作個記錄備忘.

步驟

pom文件

在pom文件中引入spring-boot-starter-web,而後排除掉內置的tomcat,最後引入javax.servlet-api,修改package爲war,詳細以下

<?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 使用時須要注意parent的版本號和dependencies的版本號-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <!--引入spring boot的web-->
        <dependency>

                    <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>

主函數啓動類

主函數啓動類須要繼承SpringBootServletInitializer,重寫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:由於把spring boot自帶的tomcat排除了,因此沒法再使用main主函數啓動程序

注意事項
