jboss錯誤中的彈簧部署

我只是想將spring框架添加到我的項目中，但是當我嘗試在jboss 6.1.0 Final中部署我的war文件時，它提供了一個錯誤。我得到以下錯誤，jboss錯誤中的彈簧部署

11:01:46,556 INFO [STDOUT] ERROR: org.springframework.web.context.ContextLoader - Context initializ 
ation failed 
11:01:46,557 INFO [STDOUT] org.springframework.beans.factory.BeanCreationException: Error creating 
bean with name 'com.tapgift.merchant.integration.spring.DaoFactoryPostProcessor#0' defined in class 
path resource [config/dao-defs.xml]: Cannot resolve reference to bean 'DAOFactory' while setting bea 
n property 'daoFactory'; nested exception is org.springframework.beans.factory.BeanCreationException 
: Error creating bean with name 'DAOFactory' defined in class path resource [config/dao-defs.xml]: I 
nvocation of init method failed; nested exception is java.lang.NullPointerException

這道def.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"> 

    <!-- All DAO bean definitions goes here --> 
    <bean id="DAOFactory" 
     class="com.tapgift.merchant.integration.db.dao.jdbc.JdbcDaoFactoryImpl" /> 

    <bean class="com.tapgift.merchant.integration.spring.DaoFactoryPostProcessor"> 
     <property name="daoFactory" ref="DAOFactory" /> 
    </bean> 

    <bean id="merchantDao" 
     class="com.tapgift.merchant.integration.db.dao.jdbc.JdbcMerchantDao"> 
     <property name="dataSource" ref="dataSource" />  
     <property name="queryFactory" ref="QueryFactory" />   
    </bean> 

</beans>

這是應用程序的context.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> 

    <context:annotation-config /> 
    <context:component-scan base-package="com.tapgift.merchant" /> 

    <import resource="classpath:config/spring-integration.xml" /> 
    <import resource="classpath:config/dao-defs.xml" /> 
    <import resource="classpath:config/query-defs.xml" /> 
    <import resource="classpath:config/spring-support.xml" /> 


</beans>

最後這是web.xml中

<!-- The definition of the Root Spring Container shared by all Servlets and Filters --> 
<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>classpath:config/application-context.xml 
       /WEB-INF/spring/root-context.xml</param-value> 
</context-param>

哎呀，差點錯過了pom，

我可以看到編譯和彙編到war文件的所有文件。感謝，如果春天的專家能指出我這個部署錯誤的原因。

編輯：新增DaoFactoryImpl

package com.tapgift.merchant.integration.db.dao.jdbc; 

import java.lang.reflect.ParameterizedType; 
import java.util.HashMap; 
import java.util.Map; 

import org.springframework.beans.BeansException; 
import org.springframework.beans.factory.InitializingBean; 
import org.springframework.context.ApplicationContext; 
import org.springframework.context.ApplicationContextAware; 

import com.tapgift.merchant.integration.db.dao.BaseDao; 
import com.tapgift.merchant.integration.db.dao.DaoFactory; 
import com.tapgift.merchant.integration.db.dao.EntityBaseDao; 

/** 
* Class <code>CaseServiceImpl</code> is an implementation of the <tt>DaoFactory</tt> interface. 
*/ 
public class JdbcDaoFactoryImpl implements DaoFactory, InitializingBean, ApplicationContextAware 
{ 
    private ApplicationContext m_appCtx; 
    private Map<String, EntityBaseDao<?>> m_daoMap = new HashMap<String, EntityBaseDao<?>>(); 

    /** 
    * {@inheritDoc}. 
    */ 
    @Override 
    @SuppressWarnings("rawtypes") 
    public void afterPropertiesSet() throws Exception 
    { 
     Map<String, BaseDao> beanMap = m_appCtx.getBeansOfType(BaseDao.class); 
     for (final BaseDao dao : beanMap.values()) 
     { 
      m_daoMap.put(((EntityBaseDao) dao).getEntityType().getName(), (EntityBaseDao) dao); 
     } 
    } 

    /** 
    * {@inheritDoc}. 
    */ 
    @Override 
    public BaseDao getDao(String name) 
    { 
     return this.m_daoMap.get(name); 
    } 

    /** 
    * {@inheritDoc}. 
    */ 
    @Override 
    public <T> T getEntityDao(Class<T> clazz) 
    { 
     String entityName = ((Class) ((ParameterizedType) clazz.getGenericInterfaces()[0]).getActualTypeArguments()[0]) 
      .getSimpleName().toUpperCase(); 
     return clazz.cast(this.m_daoMap.get(entityName)); 
    } 

    /** 
    * Set method for m_appCtx 
    */ 
    @Override 
    public void setApplicationContext(ApplicationContext appCtx) throws BeansException 
    { 
     this.m_appCtx = appCtx; 
    } 

}

更新2 這個問題似乎被創建JdbbcDaoFactoryimpl例如，當我刪除了 <bean id="DAOFactory" class="com.tapgift.merchant.integration.db.dao.jdbc.JdbcDaoFactoryImpl" />與它的依賴，我可以沒有任何問題進行部署。我檢查了戰爭文件，所有彈簧罐都屬於同一版本。拼命地需要幫助。

沒關係，我能夠解決它，與Ajinkya顯示的有點相關。 對此代碼的JdbcDaoFactoryImpl問題是m_daoMap.put(((EntityBaseDao) dao).getEntityType().getName()。((EntityBaseDao) dao).getEntityType()沒有返回任何值，但爲空。我忘了重寫/刪除實際的dao實現類的特定方法。一旦我刪除該方法，我就能夠部署它，而不會面臨任何問題。

無論如何感謝您的支持。

問題：

無法解析參考豆 'DAOFactory' 同時設定豆 財產 'daoFactory';

原因：

錯誤創建名爲 'DAOFactory' 類路徑限定 資源[配置/ DAO-defs.xml]豆：init方法的調用失敗; 嵌套的例外是顯示java.lang.NullPointerException

春天不能創建的DAOFactory即JdbcDaoFactoryImpl對象，因爲它遇到了NullPointerException在初始化對象。
添加一些有助於找出確切原因的相關代碼。

更新： 看起來像下面的行導致了問題

Map<String, BaseDao> beanMap = m_appCtx.getBeansOfType(BaseDao.class);

春節沒能找到BaseDao類型的豆。確保你已經定義了一個類型的豆BaseDao

嗨Ajinkya，謝謝，用'JdbcDaoFactoryImpl'來源更新了這個問題。 – bluelabel
