spring boot jsp 404 的解決方案
1,pom.xml 通過packaging 爲jar方式
- maven spring-boot 版本
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<packaging>jar</packaging>
```
2.依賴包
```

<!-- 打包時將jsp文件拷貝到META-INF目錄下 -->
<resource>
<!-- 指定resources插件處理哪個目錄下的資源文件 -->

<!--注意此次必須要放在此目錄下才能被訪問到 -->
<targetPath>META-INF/resources</targetPath>

- application.properties
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
- 創建webapp/WEB-INF/views目錄,views目錄裏面創建jsp
- 啓動程序
@Controller
public class IndexController {
@RequestMapping("/index")
public String index() {
return "test";
}
}
@SpringBootApplication
public class Springboot2xApplication {
public static void main(String[] args)
SpringApplication.run(Springboot2xApplication.class, args);
}
}
- 右鍵啓動
2,pom.xml 通過packaging 爲war方式
build 節點不一樣
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<packaging>war</packaging>

打包出來的文件是差距的
1,創建webapp/WEB-INF/views/目錄,properties 也是一樣的,啓動方式不同
