Mybatis+SpringMVC+Spring整合

1,先添加spring支持:

    applicationContext.xml  配在WEBINF下,四个命名空间:aop,context,tx,p

    配Listener:ContextLoaderListener

2,添加SpringMVC支持:

    在web.xml中配servlet:DispatcherServlet    伪静态*.html

    在WEBINF下配MVC-servlet.xml  四个命名空间:aop,context,mvc,p

3,添加Mybatis支持:

    手动把Mybatis的相关类库添加到WEBINF下lib

    在src下新建mybatis.cfg.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>		<settings>		<setting name="logImpl" value="http://www.mamicode.com/STDOUT_LOGGING"/>	</settings>			<plugins>  	  <plugin interceptor="cn.bdqn.mybatis.plugin.PaginationInterceptor">	    	<property name="dialectClass" value="http://www.mamicode.com/cn.bdqn.mybatis.plugin.MySQLDialect"/>记得根据使用的数据库要修改方言	  </plugin>  </plugins></configuration>

 4,分包

5,MVC-servlet.xml中加东西  把验证类库放到lib下

<?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:aop="http://www.springframework.org/schema/aop"	xmlns:context="http://www.springframework.org/schema/context"	xmlns:mvc="http://www.springframework.org/schema/mvc"	xmlns:p="http://www.springframework.org/schema/p"	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">	<context:component-scan base-package="cn.bdqn.book.controller"/>		<!-- 视图解析器 -->	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"		p:prefix="/WEB-INF/view/"		p:suffix=".jsp"	/>	<!-- 基于注解的MVC配置 -->	<mvc:annotation-driven/>		<!-- 验证器 -->	 	<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">		<!-- 使用Hibernate验证框架进行验证 -->        <property name="providerClass"  value="http://www.mamicode.com/org.hibernate.validator.HibernateValidator"/>      验证器是由hibernate提供的     </bean>		<!-- 文件上传解析器 --> 	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" 		p:uploadTempDir="file:D:\temp"    	p:defaultEncoding="utf-8"    	p:maxUploadSize="209715200"	   	/></beans>

 6,applicationContext.xml 添加东西

<?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:aop="http://www.springframework.org/schema/aop"	xmlns:context="http://www.springframework.org/schema/context"	xmlns:p="http://www.springframework.org/schema/p"	xmlns:tx="http://www.springframework.org/schema/tx"	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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">		
      主容器一扫描就会把所有的对象加到自己的容器中,把子容器的也加进去,应该排除子容器中扫描
    <context:component-scan base-package="cn.bdqn.book"> <!-- 在主容器中扫描组件时,排除掉添加了@Cotroller注解的类 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" p:driverClassName="com.mysql.jdbc.Driver" p:url="jdbc:mysql:///Book" p:username="book" p:password="123456" /> <!-- 配置SQLSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" p:dataSource-ref="dataSource" p:mapperLocations="classpath:cn/bdqn/book/mapper/*.xml" p:typeAliasesPackage="cn.bdqn.book.entity" p:configLocation="classpath:mybatis.cfg.xml" /> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" p:dataSource-ref="dataSource" /> <!-- 事务增强 --> <tx:advice id="txAdvice"> <tx:attributes> <tx:method name="*"/> </tx:attributes> </tx:advice> <!-- 事务切面 --> <aop:config> <aop:pointcut expression="execution(* cn.bdqn.book.service..*.*(..))" id="txMethods"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txMethods"/> </aop:config> <!-- 扫描指定的包,根据映射自动生成Mapper实现类对象 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="cn.bdqn.book.mapper" /></beans>

 7,显示添加表单(po专门用来做数据持久化操作的,vo表单)

添加注解,配访问路径,以get方式显示表单

自己单独建表单对象,不要用实体类。有时候表单不一定就和实体类一一对应

package cn.bdqn.book.controller.book;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import cn.bdqn.book.form.BookForm;@Controller@RequestMapping("/")public class AddBookController {	//在执行请求处理方法之前会先调用getForm方法,把对象添加到数据模型中,再调用showForm方法,这个对象就可以到表单了	@ModelAttribute("form")	public BookForm getForm(){		return new BookForm();	} 		//显示添加图书表单	@RequestMapping(value="http://www.mamicode.com/add",method=RequestMethod.GET)	public String ShowForm(){		return "add";//	}}

 改造页面  form标签

写mapper包


 

动态下拉列表

<form:select path="pid" items="${publishers}" itemLabel="name" itemValue="http://www.mamicode.com/id"/>                	<%--                	<form:select path="pid" cssClass="text">                		<form:option value="">请选择出版社</form:option>                		<form:option value="http://www.mamicode.com/1">人民邮电出版社</form:option>                		<form:option value="http://www.mamicode.com/2">电子工业出版社</form:option>                		<form:option value="http://www.mamicode.com/3">机械工业出版社</form:option>                		<form:option value="http://www.mamicode.com/4">清华大学出版社</form:option>                		<form:option value="http://www.mamicode.com/5">水利出版社</form:option>                	</form:select>                    	 --%>   


package cn.bdqn.book.controller.book;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import cn.bdqn.book.entity.Publisher;
import cn.bdqn.book.form.BookForm;
import cn.bdqn.book.service.publihser.IPublihserService;

@Controller
@RequestMapping("/")
public class AddBookController {
    //把图书列表拿出来
    private IPublihserService publihserService;
    @Autowired
    public void setPublihserService(IPublihserService publihserService) {
        this.publihserService = publihserService;
    }
    
    //在执行请求处理方法之前会先调用getForm方法,把对象添加到数据模型中,再调用showForm方法,这个对象就可以到表单了
    @ModelAttribute("form")//将表单数据对象存入数据模型
    public BookForm getForm(){
        return new BookForm();
    }
    
    //把图书列表放进模型中,将
    @ModelAttribute("publishers")//将动态加载的出版社列表存入数据模型
    public List<Publisher> getPublishers(){
        return publihserService.findPublisher();
    }
    
    //显示添加图书表单
    @RequestMapping(value="http://www.mamicode.com/add",method=RequestMethod.GET)
    public String ShowForm(){
        return "add";//
    }
    
    //
}

 文件上传

导入  commons-io-1.3.2.jar  跟commons-upload  一起配合使用(不用自己导入了)

<form:form method="post" modelAttribute="form" enctype="multipart/form-data">

<!-- 文件上传解析器 --> 	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" 		p:uploadTempDir="file:D:\temp"    	p:defaultEncoding="utf-8"    	p:maxUploadSize="209715200"	   	/>

 在bookform类中

//图片
        private MultipartFile pic;
