概述
1.Spring Boot聚合工程打包war部署Tomcat
2.Spring Boot打包Jar,通过Java -jar直接运行.
3.提供完整pom.xml测试项目 至github
解决问题
1.xxxx中没有主清单属性
2.解决没有web.xml而报错
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project provider: Error assembling WAR: webxml attribute is required(or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]
版本
1.JDK 1.8
2.Spring Boot 1.5.8
3.apache-tomcat-8.5.23
一.
打包war部署tomcat
1.改写App类 继承SpringBootServletInitializer
2.重写configure方法,返回builder.sources(YouApp.class);
3.添加pom.xml ,如下图
4.修改<packaging>war</packaging>
5.package命令打包
6.可参考 github--> releases--> v0.1 中blog-main-service 它是一个可打包jar且通过java -jar运行的完整项目配置
地址:https://github.com/mmdsyl/BLOG-Microservice/releases
public class ManagerApplication extends SpringBootServletInitializer{
// for tomcat
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(ManagerApplication.class);
}
public static void main(String[] args) throws InterruptedException {
SpringApplication application = new SpringApplication(ManagerApplication.class);
//application.setBannerMode(Banner.Mode.OFF);
application.run(args);
}
}
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<!--用于解决没有web.xml报错-->
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
</plugin>
二.
打包Jar执行运行
1.标准的Application,不要继承SpringBootServletInitializer
2.修改pom,如图
3.package命令打包
4.可参考 github--> releases--> v0.1.1 中blog-main-web ,它是一个可打包war可部署tomcat中的完整配置
地址:https://github.com/mmdsyl/BLOG-Microservice/releases
<!--打包成jar-->
