spring boot 部署到tomcat

網上很多文章描述過，當我按步驟做時會拋各種錯誤，最后記錄下我的做法(成功發布到本地 Tomcat9 ):

1.將項目的啟動類Application.java繼承SpringBootServletInitializer並重寫configure方法

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;

import javax.servlet.MultipartConfigElement;


@SpringBootApplication
public class Application extends SpringBootServletInitializer {

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(Application.class);
	}

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

2.在pom.xml文件中，project下面增加package標簽

<packaging>war</packaging>

 

完成以上2步我就可以打包了

1.先進入項目根目錄(eg: D:\jhipster_project\demo )，執行 mvn clean package ,將項目打包為war包。

2. 將target 目錄中的 demo-0.0.1-SNAPSHOT.war 文件復制到你所安裝的tomcat目錄中webapps目錄中,然后去掉工程后邊的后綴，變成 demo.war

   需要注意的是這樣部署的request url需要在端口后加上項目的名字才能正常訪問

  eg:  http://localhost:8080/demo/***

 

最后記錄下我的pom.xml

其實也可以在創建 spring boot 項目時選擇 Packaging:war
