Question

提问by charles

Recently I use spring STS with roo 1.2.0.M1 to build a web project. I set up the jpa and create a entity with some field and create a repository and a service layer for the entity, and then when I perform tests, it gives me the following error:

最近在用spring STS和roo 1.2.0.M1搭建一个web项目。我设置了 jpa 并创建了一个带有某个字段的实体，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：

I use the following commands to build the project:

我使用以下命令来构建项目：

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

This is the configuration of the maven plugin:

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>

After I finish the above job, and run perform teststhrough STS roo shell, and I get the above error.

完成上述工作后，并perform tests通过 STS roo shell运行，出现上述错误。

Is there anyone know that why this exception occurs? Do I do something wrong? And how to fix it?

有没有人知道为什么会发生这个异常？我做错了什么吗？以及如何修复它？

Please help me!

请帮我！

Thank you in advance!

先感谢您！

One or more tests are not working.

一项或多项测试无效。

Have a look at the files located at: /Users/charlesli/Documents/workspace-spring/WebApplication/target/surefire-reports(usually the bigger files contain a problem)

查看位于以下位置的文件：（ /Users/charlesli/Documents/workspace-spring/WebApplication/target/surefire-reports通常较大的文件包含问题）

There you will find the test results, and the test that is broken. The Stacktrace containing in this file will guide you to the problem.

在那里你会找到测试结果，以及被破坏的测试。此文件中包含的 Stacktrace 将引导您解决问题。

(BTW: you can run the tests in eclipse via JUnit plugin (Package explorer, right click, run as JUnit) too, then you will see the stack trace in the IDE and do not need to search in the files.)

（顺便说一句：您也可以通过 JUnit 插件（Package explorer，右键单击，作为 JUnit 运行）在 eclipse 中运行测试，然后您将在 IDE 中看到堆栈跟踪，而无需在文件中搜索。）

I guess, that the DB connection is not correct. But this is only a guess.

我猜，数据库连接不正确。但这只是一个猜测。

Right click on Project-> Properties--> select project facets--> choose Java correct version which is installed on your system. Then it will works fine.

右键单击项目-> 属性--> 选择项目方面--> 选择系统上安装的 Java 正确版本。然后它会正常工作。

You can replace the environment from jre to jdk as follows if it also shows compiler unavailable :

如果还显示编译器不可用，您可以将环境从 jre 替换为 jdk，如下所示：

project_name > Build Path > Configure Build Path > Libraries > (double-click) JRE System Libraries > Alternate Jre : jdk 1.8 >ok
Then from Installed JRES option in Libraries select jdk 1.8
Project > Clean
Maven > Update

项目名称 > 构建路径 > 配置构建路径 > 库 >（双击）JRE 系统库 > 备用 Jre：jdk 1.8 >ok
然后从库中的已安装 JRES 选项中选择 jdk 1.8
项目 > 清洁
Maven > 更新
