hibernate4.0+spring3.1+struts2.2.3集成问题

Question

hibernate4.0+spring3.1+struts2.2.3集成问题，自己配置数据源datasSource值和hibernate.cfg.xml中的值是一样的运行没有问题，但是配置SessionFactory的configLocation属性时出现异常：
hibernate.cfg.xml如下：
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/oa</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">5589</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.show_sql" >true</property>
<mapping resource="interview/test/bean/Person.hbm.xml"/>
</session-factory>
</hibernate-configuration>application-common.xml如下：<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" scope="prototype">
  <property name="configLocation" >
  <value>classpath:hibernate.cfg.xml</value>
  </property>
  </bean> 
  <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
  <property name="sessionFactory">
  <ref bean="sessionFactory"/>
  </property>
  </bean>
异常：

Answer 1

Error creating bean with name 'personManager'这一句personManager这个bean有问题
Invocation of init method failed; nested exception is java.lang.NullPointerException
初始化失败，空指针异常

Answer 2

试试在application-common.xml的最后面加上自动default-autowire="byName"试试
<beans
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" default-autowire="byName">

Answer 3

我查了一下
org.springframework.orm.hibernate4.LocalSessionFactoryBean里面并没有mappingLocation这个属性，只有一个mappingLocations，楼主，你是不是写错了？

Answer 4

晕，我拷贝错了，
是configLocations，不是configLocation。把configLocation改为configLocations。

Answer 5

personManager这个bean有问题要是有问题的话，在自己配置数据源datasSource里也会报错，应该不是这的问题

Answer 6

把configLocation改为configLocations。异常一样如下

Answer 7

你的sessionFactory配置有问题啊，dataSource都没引入。

Answer 8

不是说配置了下面这个属性就不用在配数据源了吗
<property name="configLocation" >
  <value>classpath:hibernate.cfg.xml</value>
  </property>

Answer 9

那你的mappingResources在哪里呢？

Answer 10

连接的基本信息都可以在hibernate.cfg.xml中读取，另外配数据源的方案已经运行了没有问题，我是想试试这种方式为什么就运行不了

Answer 11

csdn里就没有人能帮我解决这个问题吗？下面这段代码测试可以导出表
public void testExport(){
Configuration cfg=new Configuration().configure();
SchemaExport ext=new SchemaExport(cfg);
ext.create(true,true);




}下面这段代码测试出异常：
public void testSpringHibernate(){
ClassPathXmlApplicationContext cxt=new ClassPathXmlApplicationContext("applicationContext-*.xml");
PersonManager personManager=(PersonManager)cxt.getBean("personManager");
System.out.println(personManager);
DataSource dataSource=(DataSource)cxt.getBean("dataSource");
System.out.println(dataSource);
// SessionFactory sessionFactory=(SessionFactory)cxt.getBean("sessionFactory");
// System.out.println(sessionFactory);

try {
System.out.println(dataSource.getConnection());
String string1=dataSource.getConnection().getMetaData().getUserName();
System.out.println(dataSource.getConnection().getClientInfo());
System.out.println(string1);


} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
