springboot打jar包和war包部署

jar包部署，在web模块pom.xml修改

因为在创建web模块时指定的打包方式是jar，所以只需修改以下配置即可

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.zm.web.WebApplication</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

使用maven下的package进行打包

找到jar包位置,cmd进入命令

输入 cmd指令 java -jar web-0.0.1-SNAPSHOT.jar

测试一下，成功访问

war包部署

修改web模块下pom.xml打包方式

<packaging>war</packaging>

web模块下pom.xml排除内置的Tomcat容器

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <!-- 打war包新增 -->
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
            <!-- 打war包新增  -->
        </dependency>

参考连接: https://blog.csdn.net/weixin_30329623/article/details/99421450.

        <!-- 打war包 -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>8.5.23</version>
        </dependency>
        <!-- 打war包 -->

注释web模块下pom.xml的打jar包配置

			<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.zm.web.WebApplication</mainClass>
<!--                    <layout>ZIP</layout>-->
                </configuration>
<!--                <executions>-->
<!--                    <execution>-->
<!--                        <goals>-->
<!--                            <goal>repackage</goal>-->
<!--                        </goals>-->
<!--                    </execution>-->
<!--                </executions>-->
            </plugin>

web模块下pom.xml新增打war包配置

		<!-- 指定打war包生成的项目名称 -->
        <finalName>web</finalName>

            <!-- 打war包 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>

最终web模块下的pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

配置步骤：
1、继承SpringBootServletInitializer
外部容器部署的话，就不能依赖于Application的main函数了，而是要以类似于web.xml文件配置的方式来启动Spring应用上下文，此时我们需要在启动类中继承SpringBootServletInitializer并实现configure方法：
这个类的作用与在web.xml中配置负责初始化Spring应用上下文的监听器作用类似，只不过在这里不需要编写额外的XML文件了。

package com.zm.web;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication(scanBasePackages = "com.zm")
@MapperScan("com.zm.dao")
public class WebApplication extends SpringBootServletInitializer {

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

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

}
