1. 首先看下pom.xml里面的东西

1.1 依赖

<dependencies>
    <!--  Web  -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

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

    <!--  Tomcat for jsp  -->
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>

    <!--  Servlet  -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <scope>provided</scope>
    </dependency>
    <!--  JSTL  -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>

    <!--  开发时页面修改后会立即生效  -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
</dependencies>

1.1 分享下项目结构

1.3 核心部分

需要注意1.spring-boot-maven-plugin 一定要引入，会导致404报错。版本1.4.2的才可以

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>1.4.2.RELEASE</version>
        </plugin>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/**</include>
            </includes>
            <!-- 开启过滤，用指定的参数替换directory下的文件中的参数 -->
            <filtering>false</filtering>
        </resource>

        <resource>
            <!--指定resources插件处理哪个目录下的资源文件-->
            <directory>src/main/webapp</directory>
            <!--注意此次必须要放在此目录下才能访问到-->
            <targetPath>META-INF/resources</targetPath>
            <includes>
                <include>**/**</include>
            </includes>
        </resource>
    </resources>
</build>

2. 打包

3. 然后在控制台去target目录下输入

直接java -jar xxxx.jar 运行即可。完成收工。
