springboot打包部署的那些事
一、打成jar部署
利用springboot的插件打包
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>打jar的小细节
当有引入本地jar配置，如下图
pom.xml配置如下
<dependency>
<groupId>eis_protobuf</groupId>
<artifactId>eis_protobuf</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/eis_protobuf.jar</systemPath>
</dependency>springboot-maven-plugin打包的第一级目录为Boot-INF，如果不做任何配置，直接mvn clean package会发现无法把本地的jar打进Boot-INF中，则此时要做如下配置
方法一
在pom.xml的resources节点添加如下内容
<resource>
<directory>lib</directory>
<targetPath>BOOT-INF/lib/</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>ps： 如果遇到一些外部配置文件比如mybatis的mapper文件或者activiti生成器的json文件，则也要把相应的文件打进resources中，否则项目启动会因找不到配置文件，而报错，配置文件如下
<resource>
<directory>${basedir}/src/main/java</directory>
<filtering>false</filtering>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
<resource>
<directory>${basedir}/src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>templates/**</exclude>
<exclude>static/**</exclude>
</excludes>
<includes>
<include>**/*.xml</include>
<include>**/*.yml</include>
<include>**/*.yaml</include>
<include>**/*.properties</include>
<include>**/*.key</include>
<include>**/*.des</include>
<include>**/*.template</include>
<include>**/*.json</include>
</includes>
</resource>方法二
在spring-boot-maven-plugin插件中设置includeSystemScope参数
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
</plugins>
</build>二 把sprinboot部署到外部tomcat
1、修改打包方式，把jar改成war，改成如下配置
<packaging>war</packaging>2、引入tomcat依赖jar，scope范围为provided，并排除springboot内嵌的tomcat依赖jar，其实不排除也没关系，不影响项目运行
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>3、修改打包插件，不使用spring-boot-maven-plugin插件打包，因为这个打包插件会把jar打包在Boot-INF目录下导致别的项目引用时引用不到，此时改用maven-war-plugin打包，具体配置如下
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>4、修改启动类，启动类继承SpringBootServletInitializer，并重写configure方法
@SpringBootApplicationpublic class SpringbootDemo extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SpringbootDemo.class);
}
public static void main(String[] args) {
new SpringApplicationBuilder(SpringbootDemo.class).web(true).run(args);
}
