Question

我对Java及其工具完全不熟悉，我想使用Dropwizard框架。我在其repository中找到了一个示例，但我无法运行它。

正如README.md中所述，我需要运行mvn package。但是，据我所知，Maven尝试运行集成测试，但抛出了异常。堆栈跟踪如下：

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 5.975 sec << FAILURE! - in com.example.helloworld.IntegrationTest
com.example.helloworld.IntegrationTest  Time elapsed: 5.974 sec  <<< ERROR!

我认为它在语言环境方面存在一些问题，因为我的操作系统是 OS X 10.11土耳其语，我们将字符串'i'大写为'İ' ，而非'我'。

我正在使用 IntelliJ IDEA ，您能告诉我如何更改被测试人员的当前区域设置（我不知道它是 JVM 或< em> Maven 或其他东西......）？

根据要求，我的migrations.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
         http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.1.xsd">

    <changeSet id="1" author="codahale">
        <createTable tableName="people">
            <column name="id" type="bigint" autoIncrement="true">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="fullName" type="varchar(255)">
            <constraints nullable="false"/>
            </column>
            <column name="jobTitle" type="varchar(255)"/>
        </createTable>
    </changeSet>
</databaseChangeLog>

Answer 1

它应该是由Java虚拟机（JVM）的区域设置引起的。

只需打开终端或控制台（对于Windows）并运行以下命令，即可将您的语言环境更改为英语。

plot(Score, y, type="l") polygon(c( Score[Score>=1250], max(Score), 1250 ), c(y[Score>=1250],0, 0 ), col="skyblue")

要使其自动化，您可能需要在终端启动脚本中导出环境变量，例如set JAVA_ARGS=-Duser.language=en -Duser.region=US %JAVA_ARGS%。
