springboot 部署到外部tomcat

• 入口类继承SpringBootServletInitializer
• 并重写protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)方法 如下

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
@ServletComponentScan
public class MoviesApplication extends SpringBootServletInitializer {

public static void main(String[] args) {
SpringApplication.run(MoviesApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// 注意这里要指向原先用main方法执行的Application启动类
return builder.sources(MoviesApplication.class);
}
}

• 必须创建一个war项目
• 在pom.xml文件中将嵌入式Tomcat指定为provided

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