问题
I have a spring XML config file called appConfig.xml which contains a datasource bean and another JDBCtemplate to which datasource is passed as an argument:
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/test"/>
</bean>
<bean id="JDBCTemplate" class="com.myprojects.JDBCTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
I get an error :
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'JDBCTemplate' defined in file [appConfig.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'dataSource' threw exception; nested exception is java.lang.IllegalArgumentException: Property 'dataSource' is required
From what I see from this error, it is not able to pass dataSource to JDBCTemplate. The logs also says:
Loaded JDBC driver: com.mysql.jdbc.Driver
I have all dependencies mentioned in pom.xml and I verified that necessary jars for spring are loaded and mysql jdbc connector is also loaded. Any clues on what the issue may be?
I tried a different project where I manually added all spring dependencies and mysql jdbc connector as part of library. It worked fine there. But while trying to include dependencies via pom.xml, I'm facing this issue. So I'm assuming this is to do with some dependency not being pulled in or something. But unable to figure out which one from the error.
回答1:
It thinks your class JDBCTemplate does not have a property named dataSource
Perhaps you don't have a public method setDataSource() that has a single argument of the right type.
Perhaps it is private.
Perhaps it is spelled wrong.
