我试图想出一个在spring框架中加载多个配置.xml文件的程序。
这是我遇到的错误:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'JDBCTemplateFileLog' defined in class path resource [BeansFileLog.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'dataSource' threw exception; nested exception is java.lang.IllegalArgumentException: Property 'dataSource' is required
这些是我的 xml 文件:
Beans-All-Modules.xml
<import resource="BeansJDBC.xml" /> <import resource="BeansFileLog.xml" /> <import resource="BeansCFAE.xml" />
BeansJDBC.xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/TEST"/> <property name="username" value="root"/> <property name="password" value="password"/> </bean>
BeansFileLog.xml
'<bean id="JDBCTemplateFileLog" class="in.customfileaccessevent.JDBCTemplateFileLog"> <property name="dataSource" ref="dataSource" /> </bean>`
BeansCFAE.xml
<bean id="customFileAccessEvent" class="in.customfileaccessevent.CustomFileAccessEvent"> <constructor-arg index="0" type="java.lang.String"> <value>E:/HelloWorld.doc</value> </constructor-arg> </bean>
`<bean id="customEventHandler" class="in.customfileaccessevent.CustomFileAccessEventHandler" /> <bean id="customFileAccessEventPublisher" class="in.customfileaccessevent.CustomFileAccessEventPublisher" />`
我已将外部 jar 文件“MysqlConnecterJ.. .jar”添加到程序中。我仍然无法弄清楚问题是什么?
MainApp.java 程序如下:
`公共类 MainAppAllModules {
public static void main(String args[]){
ConfigurableApplicationContext context =
new ClassPathXmlApplicationContext("Beans-All-Module.xml");
//ApplicationContext context = new ClassPathXmlApplicationContext(new String[] {"BeansCFAE.xml", "BeansJDBC.xml"});
CustomFileAccessEvent ce = (CustomFileAccessEvent) context.getBean("customFileAccessEvent");
CustomFileAccessEventPublisher cvp =
(CustomFileAccessEventPublisher) context.getBean("customFileAccessEventPublisher");
cvp.publish(ce);
/*ConfigurableApplicationContext context1 =
new ClassPathXmlApplicationContext("BeansJDBC.xml");*/
JDBCTemplateFileLog flogJDBCTemplate = (JDBCTemplateFileLog) context.getBean("JDBCTemplateFileLog");
System.out.println("File Log Creation");
flogJDBCTemplate.create("Sample", "Sample");
}
}`
