我的配置檔案
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
#日志列印級别
logging.level.org.springframework=debug
logging.level.org.mybatis=debug
logging.level.org.apache.ibatis=debug
百度了半天終于發現原因
是因為jar依賴沒有導入，最後在pom檔案中添加
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
<version>4.4</version>
</dependency>
最終pom檔案是這樣的

<include>**/**</include>
</includes>
</resource>
</resources>

</project>
再次運作項目，就可以成功通路jsp頁面了。原因就是jar檔案沒有成功導入，還有一個配置需要注意
<resources>
<resource>
<!-- 指定處理哪個目錄下的資源檔案 -->
<directory>src/main/webapp</directory>
<!--注意此次必須要放在此目錄下才能被通路到-->
<targetPath>META-INF/resources</targetPath>
<includes>
<include>**/**</include>
</includes>
</resource>
</resources>
要不也加載不到jsp，需要注意。
以上就是我遇到的問題，希望對大家有幫助，同時自己也記錄一下，防止忘記。
