Spring MVC + Mybatis 整合实例

刚才写了半天图片都出错了，干脆全删了重新写了一遍。

我这里用的Myeclipse 10 Oracle 11g 

首先导入Sping jar包 等等

jar包下载地址:http:// p a n .baidu.com/s/1hqxIw4k 去掉空格即可

配置appcationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans default-autowire="byName" xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd ">
	<!-- spring组件注解扫描 -->
	<context:component-scan base-package="*.impl,web.action"></context:component-scan>
	<!-- 数据源 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
		<property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property>
		<property name="username" value="system"></property>
		<property name="password" value="ok"></property>		
	</bean>
	<!-- 会话工厂 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<!-- sql注解映射扫描 -->
	<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="dao"></property>
	</bean>	
	<!-- 声名式事务 -->
	<bean id="tran" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<tx:annotation-driven transaction-manager="tran"/>
</beans>

在导入sping - context 3.1.xsd这个文件 还有一个 spring-tx-3.1.xsd 

在Web.xml中的<web-app>中加入

  <display-name></display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
    <servlet>
        <servlet-name>mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>0</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>mvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

声明BIz :@Service("")

package biz.impl;

import org.springframework.stereotype.Service;

import biz.UserBiz;

import dao.UsersDao;
import entity.Users;

@Service("userbiz")
public class UserBizImpl extends BaseBizImpl<UsersDao> implements UserBiz {

	@Override
	public Users login(Users user) {
		return super.getFactory().getDao(UsersDao.class).findByParam(user);
	}

	@Override
	public int adduser(Users user) {
		return super.getFactory().getDao(UsersDao.class).addbyParam(user);
	}

	@Override
	public Users selectUser(String username) {
		// TODO Auto-generated method stub
		return super.getFactory().getDao(UsersDao.class).findbyuser(username);
	}

}

声明控制器：@Controller("") 在action中 @RequestMapping("")声明方法

package web.action;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.SessionAttributes;

import entity.Users;

import biz.UserBiz;

@Controller("useraction")
@SessionAttributes("listls")
public class UsersAction {

	private UserBiz userbiz;

	public UserBiz getUserbiz() {
		return userbiz;
	}

	public void setUserbiz(UserBiz userbiz) {
		this.userbiz = userbiz;
	}

	@RequestMapping("/Login")
	public String LoginAcion(Users users, ModelMap map) {
		Users u = userbiz.login(users);
		if (u != null) {
			System.out.println("登陆成功!");
			map.put("listls", users);
			map.put("oks", 1);
			System.out.println(u.getU_id());
			return "login.jsp";
		} else {
			map.put("dl", "登陆失败，账号或者密码错误！");
			return "login.jsp";
		}

	}



}
