- 先指定jsp目录，右键项目选择properties（注意的是第三步，如果之前选中第二步的话，要去掉，apply之后再选中才会出现第三步）
第二步.pom.xml调整
2.1 打包方式修改
<packaging>jar</packaging>
变更为
<packaging>war</packaging>
2.2. 添加依赖
重点：scope是provided
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
2.3. 排除嵌入式tomcat
不排除也没影响，多个jar而已
<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>
2.4. 注释spring-boot-maven-plugin，使用maven-war-plugin
<!--
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>bing.AuthorityApplication</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin> -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
第三.启动类修改
继承SpringBootServletInitializer覆盖configure方法，示例：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
第四. 省略项目名部署方法
修改TOMCAT的server.xml，demo是项目文件夹（将path值清空就可以了）
<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">
...
<Context path="" docBase="D:/opt/demo" debug="0" reloadable="true"/>
...
</Host>
