1.pom.xml

(因?yàn)閟pring-boot-starter-thymeleaf包含了spring-boot-starter-web,所以不用引入了)

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2.增加一個(gè)類,如果新建項(xiàng)目的時(shí)候選的war,這步可以略過(guò):

package com.yunchuang;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Demo8Application.class);
    }
}

3.application.yml 定義端口號(hào)和path

server:
#  端口號(hào)
  port: 8008
  context-path: /demo8

4.thymeleaf緩存設(shè)置為false

spring:
  thymeleaf:
    cache: false

以上是代碼部分,配置完畢.下面是idea配置部分.

點(diǎn)擊工具欄上的EditConfigurations
