Java异常处理004:Springboot项目在tomcat下正常启动,但是无法访问(页面和接口)
解决方案:
第一步,在POM.XML文件引入依赖
<!-- 打war包时加入此项, 告诉spring-boot tomcat相关jar包用外部的,不要打进去 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<!-- springboot自带的tomcat并没有携带tomcat-embed-jasper的依赖,如果不引入tomcat-embed-jasper依赖,使用SPringboot启动项目则会无法成功-->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
第二部,修改Springboot启动类,继承SpringBootServletInitializer类(作用是为了支持可以不使用web.xml)
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
改成
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
对SpringBootServletInitializer类的理解,请参考:https://blog.csdn.net/zq17865815296/article/details/79464403 |
