这是我的问题,
所以这是我在 pom.xml 中的个人资料:
<profiles>
<profile>
<id>dev</id>
<activation>
<property>
<name>environment</name>
<value>dev</value>
</property>
</activation>
</profile>
<profile>
<id>prod</id>
<activation>
<property>
<name>environment</name>
<value>prod</value>
</property>
</activation>
</profile>
</profiles>
当我使用这个 context.xml 时,我的应用程序运行良好:

dataSource
但是,如果我在生产或开发中,我希望能够改变我的风格。
所以这就是我现在得到的:
<beans profile="dev">
<bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" id="dataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1521:dev" />
<property name="username" value="*****" />
<property name="password" value="*****" />
</bean>
</beans>
<beans profile="prod">
<bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" id="dataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@xxx.xxx.xxx.xxx:1522:prod" />
<property name="username" value="*****" />
<property name="password" value="*****" />
</bean>
</beans>
<beans profile="dev, prod">
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
<property name="persistenceUnitName" value="carfleetPersistenceUnit" />
<property name="dataSource" ref="dataSource" />
</bean>
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<tx:annotation-driven />
</beans>
我通过使用mvn -e -P prod help:active-profiles
该配置文件prod
在每个包中是否处于活动状态来检查它是否处于活动状态。但最后,它不起作用,我得到错误:
Caused by : org.springframework.beans.factory.NoSuchBeanDefinitionException : No unique bean of type [javax.persistence.EntityManagerFactory] is defined: expected single bean but found 0.
肯定存在错误,因为这是从“应用程序正在运行”到“应用程序有错误”的唯一更改。
编辑
我现在明白我混淆了 Spring 配置文件和 Maven 配置文件,但我仍然想链接它们中的 2 个。因此,为此,我将属性放在我的 pom.xml > profiles :
<profiles>
<profile>
<id>dev</id>
<properties>
<environment>dev</environment>
</properties>
</profile>
<profile>
<id>prod</id>
<properties>
<environment>prod</environment>
</properties>
</profile>
</profiles>
我添加了我的 web.xml :
<context-param>
<param-name>spring.profiles.active</param-name>
<param-value>${environment}</param-value>
</context-param>
当我硬编码${environment}
或dev
它prod
完美地工作时。但是当我希望能够从 Maven 切换时:clean -Pprod package tomcat7:redeploy
我遇到了以下问题:
IllegalArgumentException : Could not resolve placeholder 'environment' in string value "${environment}`
