阿里云tomcat部署web项目

在本文中,将演示如何将Spring Boot WAR文件部署到Tomcat servlet容器中。

!!!!!! 打包在你springboot项目地方打开cmd 而后输入    mvn install package
对于Spring Boot WAR部署,须要执行三个步骤:

扩展SpringBootServletInitializer
根据提供标记嵌入式servlet容器。
更新包装为 War
测试工具:

Spring Boot 1.4.2.RELEASE
Tomcat 8.5.9
Maven 3
注意
在Spring Boot中,具备嵌入服务器解决方案的最终可执行JAR文件可能不适合全部生产环境,特别是部署团队(具备良好的服务器优化和监控技能知识,但缺少开发经验的团队),他们但愿彻底控制服务器,而且不能接触代码。

1. 推展 SpringBootServletInitializer

使现有的 @SpringBootApplication 类扩展 SpringBootServletInitializer
1.1 - 经典Spring Boot JAR部署(更新此文件以支持WAR部署)。

SpringBootWebApplication.java 文件的内容以下 -

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootWebApplication {

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

}
Java
1.2 Spring Boot WAR 部署

SpringBootWebApplication.java 文件的内容以下 -

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

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

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

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

}

/*@SpringBootApplication
public class SpringBootWebApplication {

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

}*/
Java
若是要为部署建立了一个额外的SpringBootWebApplication类,请确保告诉Spring Boot要从哪一个主类开始启动程序:

在 pom.xml 文件中增长如下内容指定 -

<properties>
      <start-class>com.yiibai.NewSpringBootWebApplicationForWAR</start-class>
</properties>
XML
2.提供标记嵌入式servlet容器

在 pom.xml 文件中增长如下内容指定 -

<dependencies>

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

    <!-- marked the embedded servlet container as provided -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>

</dependencies>
XML
3.更新包装为War
在 pom.xml 文件中增长如下内容指定 -

<packaging>war</packaging>
XML
完成,mvn打包并将$project/target/xxx.war复制到Tomcat发布目录进行部署。

4. 完整的Spring Boot WAR + Tomcat部署

4.1 - 以Spring Boot Thymeleaf为例,更新它并手动部署到Tomcat。
4.2 - 更新现有的SpringBootWebApplication并让它扩展SpringBootServletInitializer类。

SpringBootWebApplication.java文件的完整代码以下所示 -

package com.yiibai;

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

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

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

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

}
Java
4.3 - 更新打包包,并按提供的标记spring-boot-starter-tomcat。
pom.xml文件的完整代码以下所示 -

<?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">

        <!-- Optional, for bootstrap -->
        <dependency>

            <artifactId>bootstrap</artifactId>

        </dependency>

    </dependencies>
    <build>
        <plugins>
            <!-- Package as an executable jar/war -->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>
XML
4.4 - 这是可选的,将contextPath更新为/yiibai以方便稍后做为演示。准备好WAR部署文件。

application.properties 文件的完整内容以下所示 -

welcome.message: Hello Yiibai

server.contextPath=/yiibai
Bash
4.5 - 获取Tomcat并部署WAR文件,执行如下命令 -

F:\worksp\springboot\spring-boot-war-tomcat>mvn clean package
[INFO] Scanning for projects...

将生成的 spring-boot-web-thymeleaf-1.0.war 拷贝到 Tomcat 发布目录下 -



例如,写本文章时,Tomcat 发布目录使用的是 - F:\worksp\springmvc\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\webapps
