後的指令web Roo的網站如下：Spring Roo的2部署
mkdir hello
cd hello
roo.sh
roo> project setup --topLevelPackage com.foo
roo> jpa setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY
roo> entity jpa --class ~.domain.Timer
roo> field string --fieldName message --notNull
roo> repository jpa --all
roo> service --all
roo> web mvc setup
roo> web mvc view setup --type THYMELEAF
roo> web mvc controller --all --responseType THYMELEAF
roo> web mvc controller --all --pathPrefix /api
roo> quit
我跑
mvn package
在Roo的參考文檔（https://docs.spring.io/spring-roo/docs/2.0.x/reference/html/#using-spring-roo-create-boot-app）
描述作爲這一行動有結果是兩個罐子創建。
target/foo-1.0.0.BUILD-SNAPSHOT.jar
target/foo-1.0.0.BUILD-SNAPSHOT-exec.jar
說明說用命令
java -jar target/foo-1.0.0.BUILD-SNAPSHOT.jar
運行它，這一切順利。但是在點擊網頁上的列表項後，我收到一個異常。

注：這是使用
mvn spring-boot:run
任何想法，運行不出現的情況下，應用什麼，我做錯了什麼？
