我使用Eclipse& Maven开发了一个Spring + Hibernate webapp,在我的pom.xml
我有几个具有不同属性的配置文件,我注入了.properties
文件。这个文件在applicationContext.xml
中用于配置Spring,当我想启动应用程序时,我不得不在Eclipse外部运行的tomcat上部署它。以下是我的代码的一些部分:
pom.xml:
...
<profile>
<id>development</id>
<properties>
<db.driverClassName>com.mysql.jdbc.Driver</db.driverClassName>
<db.name>mydbname</db.name>
<db.params>?createDatabaseIfNotExist=true&amp;useUnicode=true&amp;characterEncoding=utf-8</db.params>
<hibernate.hbm2ddl.auto>update</hibernate.hbm2ddl.auto>
<hibernate.show_sql>true</hibernate.show_sql>
<log4j.spring.level>WARN</log4j.spring.level>
<log4j.hibernate.level>WARN</log4j.hibernate.level>
</properties>
</profile>
...
application.properties:
...
# JDBC Information
# Some properties are in my .m2/settings.xml
jdbc.driver.classname=${db.driverClassName}
jdbc.url=${db.url}/${db.name}${db.params}
jdbc.user=${db.username}
jdbc.pass=${db.password}
...
applicationContext.xml:
...
<!-- JDBC Data Source -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver.classname}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.user}" />
<property name="password" value="${jdbc.pass}" />
</bean>
...
使用Tomcat7 Maven插件,通过mvn tomcat7:deploy
进行部署可以正常工作,但是当我选择&#34时,右键单击&gt;以&gt;运行在服务器&#34; 上运行,我得到了很多与占位符相关的例外:

中获取日志?
感谢您的帮助。

发现它!
当我使用Maven Eclipse插件时,我有一个&#34; Maven&#34;项目属性下的条目(项目&gt;属性&gt; Maven)。我只需要激活&#34;开发&#34;简介,它工作!
