后的指令web Roo的网站如下：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的参考文档（https://docs.spring.io/spring-roo/docs/2.0.x/reference/html/#using-spring-roo-create-boot-app）
描述作为这一行动有结果是两个罐子创建。
target/foo-1.0.0.BUILD-SNAPSHOT.jar
target/foo-1.0.0.BUILD-SNAPSHOT-exec.jar
说明说用命令
java -jar target/foo-1.0.0.BUILD-SNAPSHOT.jar
运行它，这一切顺利。但是在点击网页上的列表项后，我收到一个异常。

注：这是使用
mvn spring-boot:run
任何想法，运行不出现的情况下，应用什么，我做错了什么？
