最近我使用spring STS和roo 1.2.0.M1来构建一个web项目。我设置了jpa并创建了一个带有一些字段的实体，并为该实体创建了一个存储库和一个服务层，然后当我执行测试时，它给了我以下错误：

我使用以下命令构建项目：
jpa setup --database MYSQL --provider HIBERNATE --databaseName App --hostName localhost --password root --persistenceUnit app --transactionManager appTransactionManager --userName root
entity --class ~.app.domain.DomainObjBaseModel --mappedSuperclass --persistenceUnit app --transactionManager appTransactionManager
// After running the above command, I manually add the following stuff in DomainObjBaseModel, because I don't know how to customise the roo auto generate stuff
@Id @GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy = "uuid")
@Column(unique = true, name = "id", nullable = false, length=32)
private String id;
// After this action, I continue run the following commands.
entity --class ~.app.domain.Application --extends com.crazysoft.web.app.domain.DomainObjBaseModel --persistenceUnit app --transactionManager appTransactionManager --serializable --testAutomatically
repository jpa --interface ~.app.repository.ApplicationRepository --entity ~.app.domain.Application
service --interface ~.app.service.ApplicationService --entity ~.app.domain.Application
这是maven插件的配置：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
完成上述工作后，通过STS roo shell运行perform tests，我收到上述错误。
有没有人知道为什么会发生此异常？我做错了吗？以及如何解决它？
请帮助我！
提前谢谢！

一项或多项测试无效。
查看位于/Users/charlesli/Documents/workspace-spring/WebApplication/target/surefire-reports的文件（通常较大的文件包含问题）
在那里你会发现测试结果，以及破坏的测试。包含在此文件中的Stacktrace将指导您解决问题。
（顺便说一句：你可以通过JUnit插件在eclipse中运行测试（包浏览器，右键单击，以JUnit运行），然后你将在IDE中看到堆栈跟踪，而不需要在文件中搜索。）
我猜，数据库连接不正确。但这只是猜测。

右键点击Project-＆gt;属性 - ＆GT;选择项目方面 - ＆gt;选择系统上安装的Java正确版本。然后它会正常工作。

如果还显示编译器不可用，则可以按照以下方式将环境从jre替换为jdk：
