springboot 一般使用jar 的方式运行，我们需要将程序放到tomcat环境下运行。
步骤如下：
1.修改pom文件。
排除内置的tomcat
<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>
修改打包方式
<packaging>war</packaging>
jar的方式改成 war打包。
2.修改启动代码
@SpringBootApplication
@ImportResource("classpath:transaction.xml")
@MapperScan({"com.neo.dao"})
public class DemoApplication extends SpringBootServletInitializer { public static void main(String[] args) {
SpringApplication app=new SpringApplication(DemoApplication.class);
app.addListeners(new ApplicationStartedEventListener());
app.addListeners(new ApplicationStartingEventListener());
app.addListeners(new ApplicationStartedEventListener2()); app.run(args);
} @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
} }
增加代码
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
} 3.进行打包
将打包后的代码放到tomcat下执行就可以了。
