maven打包发布

打出jar

打包过程

1： packaging改成jar

jar

2：加上一个build插件指向入口函数

    <artifactId>a_01_eurecaServer</artifactId>

    <!--这个地方一定是jar-->
    <packaging>jar</packaging>

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

    </parent>

    <dependencies>
        <dependency>

            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.2.2.RELEASE</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <!--com.EurecaServer是入口类-->
                    <mainClass>com.EurecaServer</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
    
</project>

3、打包

找到idea的maven 找到要打包的项目点击package

打出war

war包介绍：

war包本身不能使用，但是tomcat可以直接识别

如果把war包放到tomcat的webapps目录，启动tomcat就会直接自动解压war包，解压出来就是一个完整的项目，用tomcat是可以直接访问的。

打包过程

1：package改成war

2：入口函数要继承SpringBootServletInitializer

如果不继承SpringBootServletInitializer 将会出现404

@SpringBootApplication
@EnableEurekaClient
public class UserApp extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(UserApp.class);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(UserApp.class);
    }
}

3、pom文件

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <!--这里改成你自己的入口类-->
                    <mainClass>com.UserApp</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
