Question

我在pom.xml文件中包含了我的数据库配置，以便将它们用于我的项目测试，我使用unitils进行数据库集成我的pom.xml属性是

    <test.database.rules-satellite.driver>com.mysql.jdbc.Driver</test.database.rulessatellite.driver>
    <test.database.rules-satellite.server>localhost</test.database.rules-satellite.server>
    <test.database.rules-satellite.schema>R133_isp_copie_pdx</test.database.rules-satellite.schema>
    <test.database.rules-satellite.url>jdbc:mysql://${test.database.rules-satellite.server}/${test.database.rules-satellite.schema}</test.database.rules-satellite.url>

    <test.database.rules-satellite.username>junit</test.database.rules-satellite.username>
    <test.database.rules-satellite.password>junit</test.database.rules-satellite.password>

我的unitils配置如下：

# Properties for the`enter code here` PropertiesDataSourceFactory
database.driverClassName=com.mysql.jdbc.Driver
database.url=jdbc:mysql://${test.database.rules-satellite.server}/${test.database.rules-satellite.schema}

# This property specifies the underlying DBMS implementation. Supported values are 'oracle', 'db2', 'mysql' and 'hsqldb'.
# The value of this property defines which vendor specific implementations of DbSupport and ConstraintsDisabler are chosen.
database.dialect=mysql

# user properties
database.userName=${test.database.rules-satellite.username}
database.password=${test.database.rules-satellite.password}
database.schemaNames=${test.database.rules-satellite.schema}

当我运行测试时，我得到以下错误：

开始嵌入异常

java.net.UnknownHostException
MESSAGE: ${test.database.rules-satellite.server}

堆栈跟踪：

java.net.UnknownHostException: ${test.database.rules-satellite.server}
    at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
    at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:849)
    at java.net.InetAddress.getAddressFromNameService(InetAddress.java:1202)
    at java.net.InetAddress.getAllByName0(InetAddress.java:1153)
    at java.net.InetAddress.getAllByName(InetAddress.java:1083)
    at java.net.InetAddress.getAllByName(InetAddress.java:1019)

我认为maven属性没有被传播，这就是为什么unitils不能识别它们。

Answer 1

正如Marcin Krasowski所说，你需要使用资源插件，即只需添加

<build>
  <resources>
    <resource>
       <directory>(path to the parent directory of your unitils conf file)</directory>
       <filtering>true</filtering>
    </resource>
  </resources>
</build>

默认情况下，Maven不会替换所有文件中的${}变量，而是告诉它使用资源插件执行此操作。

您需要使用具有过滤选项的maven资源插件。可在此处找到更详细的说明：http://www.manydesigns.com/en/portofino/portofino3/tutorials/using-maven-profiles-and-resource-filtering/#TOC-Resource-filtering
