IDEA springboot 打成war包，并在本地tomcat部署

1. 修改pom.xml

    1.1修改打包类型为war

[code]<packaging>war</packaging>

   1.2 屏蔽tomcat

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

  或者

[code]<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>

2. 修改启动类

    增加SpringApplicationBuilder configure方法

[code]@SpringBootApplication
public class TestApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(TestApplication.class);
}

}

3, 通过maven project package 打包成war包

4 ，放入tomcat里面的websapp里面，启动tomcat即可

FAQ：1. 在屏蔽tomcat后，根据代码的写法可能出现打war包出现javax.servlet.http不存在

               此时，需要手动导入tomcat/lib/servlet-api.jar 

               导入File ->project structure ->Libraries ->add 

          2. 屏蔽tomcat后，yml里面配置的端口就无用了。
