问题描述
小弟想用spring mvc 整合hibernate 但是spring总是如法注入。 spring配置文件如下<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans><bean id="jdbcPropertyConfiger"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:jdbc.properties</value></list></property></bean><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass"><value>${datasource.driverClassName}</value></property><property name="jdbcUrl"><value>${datasource.url}</value></property><property name="user"><value>${datasource.username}</value></property><property name="password"><value>${datasource.password}</value></property><property name="acquireIncrement"><value>${c3p0.acquireIncrement}</value></property><property name="initialPoolSize"><value>${c3p0.initialPoolSize}</value></property><property name="minPoolSize"><value>${c3p0.minPoolSize}</value></property><property name="maxPoolSize"><value>${c3p0.maxPoolSize}</value></property><property name="maxIdleTime"><value>${c3p0.maxIdleTime}</value></property><property name="idleConnectionTestPeriod"><value>${c3p0.idleConnectionTestPeriod}</value></property><property name="maxStatements"><value>${c3p0.maxStatements}</value></property><property name="numHelperThreads"><value>${c3p0.numHelperThreads}</value></property></bean><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource"><ref bean="dataSource" /></property></bean><bean id="transactionInterceptor"class="org.springframework.transaction.interceptor.TransactionInterceptor"><property name="transactionManager" ref="transactionManager"></property><property name="transactionAttributes"><props><prop key="query*">PROPAGATION_REQUIRED,readOnly</prop><prop key="save*">PROPAGATION_REQUIRED</prop><prop key="delete*">PROPAGATION_REQUIRED</prop><prop key="update*">PROPAGATION_REQUIRED</prop></props></property></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="mappingResources"><list><value>classpath:ac02.hbm.xml</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop></props></property></bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="QscDBService" class ="com.qsc.m.QscDBServiceImpl"><property name="sessionFactory" ref="sessionFactory" /><property name="hibernateTemplate" ref="hibernateTemplate" /></bean><bean id="ControllerJoin" class="com.qsc.c.ControllerJoin"><property name="QscDBService" ref="QscDBService"></property> </bean></beans>QscDBservice类如下package com.qsc.m;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.jdbc.datasource.DataSourceUtils;import org.springframework.orm.hibernate3.HibernateTemplate;import com.qsc.pojo.ac02;public class QscDBServiceImpl extends JdbcTemplate implements QscDBService {private HibernateTemplate hibernateTemplate;public HibernateTemplate getHibernateTemplate() {return hibernateTemplate;}public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {this.hibernateTemplate = hibernateTemplate;}public void sava(ac02 ac02) {hibernateTemplate.save(ac02);}ControllerJoin类如下package com.qsc.c;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;import com.qsc.m.QscDBService;import com.qsc.pojo.ac02;import com.qsc.spring.ContextLoaderListener;public class ControllerJoin implements Controller {private QscDBService qsc;public QscDBService getQsc() {return qsc;}public void setQsc(QscDBService qsc) {this.qsc = qsc;}public ModelAndView handleRequest(HttpServletRequest arg0,HttpServletResponse arg1) throws Exception {//final QscDBService qsc = (QscDBService)ContextLoaderListener.getBean("QscDBService");ac02 ac02 = new ac02();String aac001 = arg0.getParameter("account");String aac002 = arg0.getParameter("name");String aac003 = arg0.getParameter("age");String aac004 = arg0.getParameter("email");String aac005 = arg0.getParameter("phone");String aac006 = arg0.getParameter("pass");ac02.setAac001(aac001);ac02.setAac002(aac002);ac02.setAac003(Integer.parseInt(aac003));ac02.setAac004(aac004);ac02.setAac005(aac005);ac02.setAac006(aac006);qsc.sava(ac02);return new ModelAndView("success");}}debug后发现 qsc和hibernatetemplate 这两个全是null 说明spring没注入成功，这是为啥啊？谢谢
解决方案
注入的名字要和配置文件中一致 比如qsc，你在 <property name="qsc" ref="QscDBService"></property>
