SpringBoot基于Maven的打包与部署

### jar方式启动 ###

我们知道SpringBoot内置了tomcat，可以直接通过jar方式启动与部署，不过在打包前，需要在POM文件中添加spring-boot-maven-plugin插件。

<build>
            <plugins>
                ...
    
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <mainClass>com.hujy.dubbo.dubboclient.DubboClientApplication</mainClass>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>

启动类

@SpringBootApplication
    public class DubboClientApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(DubboClientApplication.class, args);
        }
    }

再定义一个web访问入口。

@RestController
    public class DubboController {
    
        @GetMapping("/test")
        public String test() {
            return "测试一下";
        }
    }

通过Maven打包：mvn clean package

启动target/目录下生成的jar包：java -jar dubbo-client-1.0.0.jar

### 外置tomcat启动 ###

首先在POM文件中将打包方式改为war，然后引入tomcat相关依赖，spring-boot-starter-web中包含了spring-boot-starter-tomcat。

<packaging>war</packaging>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>javax.servlet-api</artifactId>
                <version>3.1.0</version>
                <scope>provided</scope>
            </dependency>
        </dependencies>

将启动类继承SpringBootServletInitializer类，重写configure方法。

@SpringBootApplication
    public class DubboClientApplication extends SpringBootServletInitializer {
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder applicationBuilder){
            return applicationBuilder.sources(DubboClientApplication.class);
        }
    
        public static void main(String[] args) {
            SpringApplication.run(DubboClientApplication.class, args);
        }
    
    }

通过Maven进行打包：mvn clean package

将target/目录下生成的war包（dubbo-client-1.0.0.war）复制到tomcat的webapps路径下。

通过命令或批处理启动tomcat

输入地址，测试一下。

注意这里需要加上项目名，即war包的名称，否则会报404。
