springboot labeled war package, pro-test (anti-dementia)

 1. The first packaging of jar into war

<packaging>war</packaging>

2. Add dependence

<!--添加servlet-api的依赖,用来打war包  -->
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <scope>provided</scope>
</dependency>

3. Remove or modify the built-tomcat built for the external toncat

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!--移除嵌入式tomcat插件-->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<! - use springboot comes with tomcat ->

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

4. Start Modify SpringBootServletInitializer class inherits and overrides a method in which configure

 The method of rewriting code:

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builber){
    //此处Application.class替换为springboot默认启动类
    return builber.sources(KndApplication.class);
}

5.IDEA use maven command first and then clean package, clean look, the smaller the chance of error,

If the eclipse right-click the project, select run as-> maven clean, then run as-> maven install.
