1 部署到外部Tomcat中

	<groupId>com.user</groupId>
	<artifactId>zjsz-user</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>



	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<!-- 移除tomcat插件 -->
			<exclusions>
				<exclusion>

				</exclusion>
			</exclusions>
		</dependency>
		<!-- 移除之后会报错，加入下面的依赖 -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<scope>provided</scope>
		</dependency>
		
	</dependencies>

	<build>
		<plugins>

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<warName>user</warName>  <!--外部访问到项目名 http://localhost:8080/user/.....-->
				</configuration>
			</plugin>
		</plugins>

		<!--将xml打包进去-->
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.xml</include>
				</includes>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
			</resource>
		</resources>
	</build>

</project>

然后在修改一下spring boot入口，继承重新SpringBootServletInitializer 里面打configure方法

@SpringBootApplication
public class ZjszUserApplication extends SpringBootServletInitializer {

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

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

}

都添加好后，打一个war出来，然后放到Tomcat中去。启动完成。。

2 已jar包方式启动

<packaging>jar</packaging>
.......................
<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<fork>true</fork>
				</configuration>
			</plugin>

			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.7.0</version>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
				</configuration>
			</plugin>

			<!-- maven打包跳过测试类-->
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<version>2.21.0</version>
				<configuration>
					<skipTests>true</skipTests>
				</configuration>
			</plugin>

		</plugins>

		<!--将xml打包进去--> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/resources</directory> </resource> </resources>
	</build>

最下面打resources最好都加一下，因为有的时候打出来都jar包并不包含resources这个文件夹，会导致启动找不到对应都配置信息。

打包完成后，java -jar xxxxx.jar 启动。效果如下
