约定不等于承诺〃 2022-06-17 12:12 210阅读 0赞

1.打成jar

1.在工程目录下使用mvn package 命令

D:\workspace01\FarmerHome>mvn package
    [INFO] Scanning for projects...
    [INFO]
    [INFO] ------------------------------------------------------------------------
    [INFO] Building FarmerHome 0.0.1-SNAPSHOT

打完jar之后可以在target里面看到jar包

2.运行jar

D:\workspace01\FarmerHome\target>java -jar FarmerHome-0.0.1-SNAPSHOT-20170425.jar
    04-25 19:31:54.536 [main] INFO  com.huike.boot.StartApplication - 服务开始启动了
    04-25 19:31:55.322 [background-preinit] INFO  org.hibernate.validator.internal.util.Version - HV0000

      '  |____| .__|_| |_|_| |_\__, | / / / /
     =========|_|==============|___/=/_/_/_/
     :: Spring Boot ::        (v1.4.3.RELEASE)
    
    04-25 19:31:55.915 [main] INFO  com.huike.boot.StartApplication - No active profile set, falling bac

    seconds (JVM running for 5.917)

如上运行成功。

3.如果运行报错找不到依赖包的class,那是因为打jar包默认是不包括依赖的，需要在pom.xml里面配置

<build>
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>

二.打成war包

1.pom.xml中，

换成

2.添加

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

3.还需要类

package com.huike.boot;
    
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.support.SpringBootServletInitializer;
    
    public class ServletInitializer extends SpringBootServletInitializer{
    
    	@Override
    	protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
    		return application.sources(StartApplication.class);
    	}
    }

或者直接在启动类中修改：

package com.huike.boot;
    
    import javax.servlet.ServletContext;
    import javax.servlet.ServletException;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.support.SpringBootServletInitializer;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.ImportResource;
    
    @SpringBootApplication
    @ImportResource("classpath:/spring/applicationContext.xml")
    //@Configuration
    @EnableAutoConfiguration
    @ComponentScan("com.huike.mapper")
    // @EnableEurekaServer
    public class StartApplication extends SpringBootServletInitializer{
    
    	@Override
    	public void onStartup(ServletContext servletContext) throws ServletException {
    		log.info("服务开始启动了");
    		SpringApplication app = new SpringApplication(StartApplication.class);
    		super.onStartup(servletContext);
    		
    		
    	}
    
    	private static final Logger log = LoggerFactory.getLogger(StartApplication.class);
    	
    	   @Override
    	    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    	        return builder.sources(StartApplication.class);
    	    }
    	
    	public static void main(String[] args) {
    		log.info("服务开始启动了");
    		SpringApplication app = new SpringApplication(StartApplication.class);
    //		app.addListeners(new StartApplicationListener());
    		app.run(args);
    	}
    }

4.使用mvn package打包之后，可以在target下找到

5.把XXXXX.war放到tomcat下运行.
