[英]Configuration issue : Bean name “dataSource” is already used in this <beans> element
Here is my problem, I want to define 2 Maven profiles, 这是我的问题,我想定义2个Maven配置文件,
one for the dev environment
and 一个用于
dev environment
,
one for the prod environment
. 一种适用于
prod environment
。
In my pom.xml, I so defined 2 profiles : 在pom.xml中,我定义了2个配置文件:
<!-- pom.xml -->
<profiles>
.....
<profile>
<id>dev</id>
<activation>
<property>
<name>environment</name>
<value>dev</value>
</property>
<activeByDefault>true</activeByDefault>
</activation>
</profile>
<profile>
<id>prod</id>
<activation>
<property>
<name>environment</name>
<value>prod</value>
</property>
</activation>
</profile>
</profiles>
and in my context.xml file, I want to use a different dataSource
according to which profile I choosed : 并且在我的context.xml文件中,我想根据选择的配置文件使用不同的
dataSource
:

I for sure did something wrong in the configuration or the utilisation of theses profiles... but I don't know what... 我肯定在配置或这些配置文件的利用方面出了点问题...但是我不知道...
I'm building with maven by using the command : 我正在通过使用命令使用maven进行构建:
mvn -e -Denvironment=dev clean package tomcat7:redeploy
But I got the error : 但是我得到了错误:
Configuration problem : Bean name "dataSource" is already used in this <beans> element.
If someone can tell me what is wrong :/ Because I test a lot of things, but it's just giving different errors, I don't know exactly what to do to fix it. 如果有人可以告诉我什么地方不对://因为我测试了很多东西,但是它只是给出了不同的错误,所以我不知道该怎么做才能解决它。
Thanks in advance ! 提前致谢 !
Profiles in xml are defined in the following way : xml中的配置文件以以下方式定义:
Your dev profile beans here : 您的开发人员档案bean在这里:
<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:@127.0.0.1:1522:******" />
<property name="username" value="******" />
<property name="password" value="******" />
</bean>
</beans>
Your Prod profile bean here : 您的产品概要文件bean在这里:
<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:@xxxx.xxxx.xxxx.xxxx:1521:******" />
<property name="username" value="******" />
<property name="password" value="******" />
</bean>
</beans>
and Common beans here : 和普通豆在这里:
<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>
</beans>
For activating a particular profile you need to set System Property as spring.profiles.active
as <your profile name>
. 要激活特定的配置文件,您需要将System Property设置为
spring.profiles.active
作为<your profile name>
。 It can also be achieved through web.xml by : 也可以通过以下方式通过web.xml实现:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>spring.profiles.active</param-name>
<param-value>production</param-value>
</init-param>
