求問(wèn)：SpringBoot 2.0.3 通過(guò)編程方式整合jsp；jsp頁(yè)面沒(méi)有渲染而是直接返回整個(gè)頁(yè)面字符串

使用springBoot整合jsp，controller，mybatis都整合好了，但是在訪問(wèn)jsp頁(yè)面的時(shí)候發(fā)現(xiàn)頁(yè)面并沒(méi)有進(jìn)行渲染，而是直接返回了整個(gè)頁(yè)面字符串。

jsp頁(yè)面如下

controller如下

@Controller
public class UserCtrl {

    @Autowired
    AccountService AccountService;

    @RequestMapping("/hello")
    public String home (HttpServletRequest request){
        Account account = AccountService.getAccountByName("Langdon");
        System.out.println(account.getAccountName());
        request.setAttribute("account",account);
        return "/helloworld";
    }
}

jsp對(duì)應(yīng)的ViewResolver bean；

已確定該路徑是生效的，如果注釋下面代碼會(huì)出現(xiàn)500異常.

    /**
     * JstlView
     */
    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

訪問(wèn) http://localhost:8080/hello 結(jié)果如下

從結(jié)果中可以看到頁(yè)面并沒(méi)有渲染
嘗試過(guò)在properties直接寫下面配置，但得到結(jié)果一樣。嘗試用別的瀏覽器訪問(wèn)，得到的結(jié)果也一樣。

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

    Accept-Ranges: bytes
    Content-Language: zh-CN
    Content-Length: 315

小曖昧

經(jīng)過(guò)1天的奮戰(zhàn)，看了很多springboot項(xiàng)目，終于找到原因；
maven配置問(wèn)題；

錯(cuò)誤配置如下：

        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>provided</scope>
            
        </dependency>

正確配置為

        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
            <scope>compile</scope>
        </dependency>

附上maven.scope的用法;
