Spring Boot项目打包

...

一打包方式

1 构建JAR包

2 构建WAR包

3 指定Main-Class

二打jar包

1 cmd进入指定项目

2 打包

mvn -Dmaven.test.skip -U clean package

结果打包失败

修改主pom文件

增加mainClass部分

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.imooc.firstappdemo.FirstAppDemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

重新打包，依然失败

根据提示，修改主pom文件，增加依赖部分

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <dependencies>
                    <dependency>
                        <groupId>com.imooc</groupId>
                        <artifactId>model</artifactId>
                        <version>0.0.1-SNAPSHOT</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <mainClass>com.imooc.firstappdemo.FirstAppDemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

重新打包，依然失败

换另外一种打包方式

mvn -Dmaven.test.skip -U clean install

依然失败

应该将下面build代码放入到web的pom中，因为web已经变成了项目的主模块

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.imooc.firstappdemo.FirstAppDemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

用 mvn -Dmaven.test.skip -U clean package 再次打包，打包成功

三 jar包启动，启动成功

四测试

五 war打包方式

<?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/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>first-app-demo</artifactId>
        <groupId>com.imooc</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>web</artifactId>
    <!--將packaging值（默认：jar）调整成war
    -->
    <packaging>war</packaging>
    <!--web依赖于persistence-->
    <!--增加persistence依赖-->
    <dependencies>
        <dependency>
            <groupId>com.imooc</groupId>
            <artifactId>persistence</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.imooc.firstappdemo.FirstAppDemoApplication</mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

六执行打包命令

mvn -Dmaven.test.skip -U clean package

出现错误
