SpringBoot(7) SpringBoot启动方式

第一种启动方式:对含有main方法的类进行 Run As Java Application

第二种方式:对项目“Maven Install”  生成jar包 在target目录下(java -jar xxxx.jar)

在pom中添加maven插件:

1 <build>
2   <plugins>
3     <plugin>
4       <groupId>org.springframework.boot</groupId>
5       <artifactId>spring-boot-maven-plugin</artifactId>
6     </plugin>
7   </plugins>
8 </build>

如果没有加,则执行jar包 ,报错如下
java -jar spring-boot-demo-0.0.1-SNAPSHOT.jar no main manifest attribute, in spring-boot-demo-0.0.1-SNAPSHOT.jar

第三种方式:war包方式启动

步骤1:

在pom.xml中将打包形式 jar 修改为war <packaging>war</packaging>

构建项目名称 <finalName>xdclass_springboot</finalName>

步骤2:修改启动类

 1 @SpringBootApplication 
 2 public class XdclassApplication extends SpringBootServletInitializer {
 3 
 4     @Override
 5     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
 6         return application.sources(XdclassApplication.class);
 7     }
 8 
 9     public static void main(String[] args) throws Exception {
10         SpringApplication.run(XdclassApplication.class, args);
11     }
12 
13 }

步骤3:maven install后,将打包出来的war包放在tomcat下,启动tomcat
