Spring Boot打包war jar 部署tomcat

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-->
    <!--https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html-->
    <plugin>
      <groupid>org.springframework.boot</groupid>
      <artifactid>spring-boot-maven-plugin</artifactid>
      <executions>
        <execution>
          <goals>
            <goal>repackage</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
