Springboot Project Fight War Package deployment Tomcat Tutorial

First, Introduction

Normally the Springboot project is started directly with a jar package, using its internal tomcat to implement MicroServices, but there may be a need to deploy to external Tomcat, and this tutorial explains how to do it.

Ii. Modification of Pom.xml

Set the Pom.xml file <packaging> node for the module to be deployed to the war

<!---<packaging>war</Packaging  >

It is possible to pack when you are prompted to find Maven-war-plugin. Add the following configuration to the <plugins> node in the Pom.xml

< plugin >    < Artifactid >maven-war-plugin</artifactid>    <version  >3.2.0</version></plugin >

Third, modify the main () method start class

Inherit the Springbootservletinitializer base class to initialize the Springboot, rewrite the Configure method inside and inject yourself in

Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;Importorg.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;ImportOrg.springframework.boot.builder.SpringApplicationBuilder;ImportOrg.springframework.boot.web.servlet.support.SpringBootServletInitializer;ImportOrg.springframework.context.annotation.ComponentScan; @ComponentScan ("Com.ysl.ts")//scan packages for common modules@SpringBootApplication (exclude = datasourceautoconfiguration.class)//Inherit the war package Springboot initialize the base class Public classWebbaseappextendsSpringbootservletinitializer {//overriding the configuration method@OverrideprotectedSpringapplicationbuilder Configure (Springapplicationbuilder application) {returnApplication.sources (Webbaseapp.class); }     Public Static voidMain (string[] args) {Springapplication.run (Webbaseapp.class, args); }}

Iv. disabling JMX internal bean monitoring (optional)

If there is a reference to a module in the war that we deploy, and the bean in this module has the following error, the two war registers the same bean.

Org.springframework.jmx.export.UnableToRegisterMBeanException:Unable to register MBean

Add the following configuration to disable JMX internal monitoring in Application.properties

Spring.jmx.enabled=false

V. Appendix Tomcat Installation

Download Tomcat Address: http://tomcat.apache.org/

Unzip to the specified directory: C:\apache-tomcat-8.5.33

1. Add Environment variables

variable Name: Catalina_home variable Value: C:\apache-tomcat-8.5.33Path added:%catalina_home%\bin

2. Enter the Tomcat directory and enter the bin to run Startup.bat (if you have a flashback, check that the environment variable is configured correctly)

Open the browser http://localhost:8080 you can see, as on behalf of the successful launch

3. Configuration Administrator

Open the Tomcat directory, enter the Conf directory, open the Tomcat-users.xml, you can add the following users, or the default comment is also OK, save the restart, close the Startup.bat window and then perform Shutdown.bat completely shut Tomcat before booting

<!--<role rolename= "Tomcat"/> <role rolename= "role1"/> <user username= "Tomcat" password= "< Must-be-changed> "roles=" Tomcat "/> <user username=" Both "password=" <must-be-changed> "roles=" Tomcat, Role1 "/> <user username=" role1 "password=" <must-be-changed> "roles=" Role1 "/> -<rolerolename= "Manager-gui"/><Userusername= "Admin"Password=""Roles= "Manager-gui"/>

Click on the Manager app to enter the admin password empty OK to enter, on behalf of the administrator configuration completed

4. Deploy the site

Put your war in a position and remember the path.

Open the Tomcat directory, enter the Conf directory, open Server.xml, and locate the host node to add the following nodes inside it

Path: Access to directory such as http://localhost:8080/ysl_web/

DocBase: The site War directory, which can be a relative path or an absolute path, will automatically decompress the war package and place it in the Tomcat WebApps directory

<path= "/ysl_web"  docBase= "d:/travelsupport/website/ Ysl-ts-web-base-1.0-snapshot.war "  debug=" 0 "  privileged=" true "  reloadable= "true"/>

Restart Tomcat, if the error is in the Tomcat logs directory to view the log, start success, click on the manager App, click/ysl_web to see your site
