大家好,又见面了,我是你们的朋友全栈君。
通过maven创建springboot项目启动出现404
-
application.properties
配置
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
- 项目结构
- 控制器方法
package com.example.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
@RequestMapping("/")
public String index() {
return "index";
}
}
- 启动项目访问
localhost:8080
,出现404
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
解决方法
-
pom.xml
添加依赖
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
-
clean
并刷新maven
- 重启并访问
localhost:8080
打包为jar
运行仍然出现404
- 打包插件版本设置为
1.4.2.RELEASE
,并且配置好资源目录
<build>
<resources>
<resource>
<directory>src/main/webapp</directory>
<!--这里必须是META-INF/resources-->
<targetPath>META-INF/resources</targetPath>
<includes>
<include>**/**</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.4.2.RELEASE</version>
</plugin>
</plugins>
</build>
