我尝试使用不同的配置文件通过maven构建项目。
我存储数据以连接到文件jdbc.properties
中的数据库:
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql://${db.connectionURL}/shopsstore?useUnicode=yes&characterEncoding=UTF-8
jdbc.username=${db.username}
jdbc.password=${db.password}
这是我的mvc-dispatcher.xml
<bean id="propertyConfig"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
p:location="WEB-INF/jdbc.properties" />
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
p:driverClassName="${jdbc.driverClassName}"
p:url="${jdbc.databaseurl}" p:username="${jdbc.username}"
p:password="${jdbc.password}" />
pom.xml
<profiles>
<profile>
<id>dev</id>
<properties>
<db.username>root</db.username>
<db.password>root</db.password>
<db.connectionURL>localhost:3306</db.connectionURL>
<db.driverClass>com.mysql.jdbc.Driver</db.driverClass>
</properties>
</profile>
<profile>
<id>prod</id>
<properties>
<db.username>prod-root</db.username>
<db.password>prod-admin</db.password>
<db.connectionURL>localhost:3306</db.connectionURL>
<db.driverClass>com.mysql.jdbc.Driver</db.driverClass>
</properties>
</profile>
</profiles>
当我运行构建时,我得到以下异常:
org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]: Could not resolve placeholder 'db.password' in string value "${db.password}"
似乎属性不可用。有什么想法会发生什么? P.S我使用的是Intellij IDEA

答案 0 :(得分:0)
您必须使用maven-resources-plugin
根据配置文件中设置的属性在构建期间自动更新jdbc.properties
。
参考 http://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html
您必须设置<filtering>true</filtering>
以在资源文件中启用属性替换
在使用网络资源时,请尝试将maven-war-plugin配置更改为
<configuration>
<webResources>
<resource>
<directory>${basedir}/src/main/webapp/WEB-INF</directory>
<filtering>true</filtering>
<targetPath>WEB-INF</targetPath>
<includes>
<include>**/jdbc.properties</include>
</includes>
</resource>
</webResources>
</configuration>
