====springmvc和mybatis整合、

===========》准备《====================

---导入jar包：

jar包明细如下：

commons-logging-1.1.1.jar

jstl-1.2.jar

//如果tomcat服务器不支jstl-1.2.jar标签----》请将此jar包放在tomcat的lib（apache-tomcat-7.0.57\lib）目录下

spring-aop-3.2.0.RELEASE.jar

spring-aspects-3.2.0.RELEASE.jar

spring-beans-3.2.0.RELEASE.jar

spring-context-3.2.0.RELEASE.jar

spring-context-support-3.2.0.RELEASE.jar

spring-jdbc-3.2.0.RELEASE.jar

spring-orm-3.2.0.RELEASE.jar

spring-test-3.2.0.RELEASE.jar

spring-tx-3.2.0.RELEASE.jar

spring-web-3.2.0.RELEASE.jar

spring-webmvc-3.2.0.RELEASE.jar

aopalliance-1.0.jar 通常Spring等其它具备动态织入功能的框架依赖此包

asm-3.3.1.jar

aspectjweaver-1.6.11.jar

cglib-2.2.2.jar

commons-dbcp-1.2.2.jar dbcp连接池

commons-pool-1.3.jar

junit-4.9.jar

log4j-1.2.17.jar

log4j-api-2.0-rc1.jar

log4j-core-2.0-rc1.jar

mybatis-3.2.7.jar

mybatis-spring-1.2.2.jar

mysql-connector-java-5.1.7-bin.jar 连接mysql数据库的jar包

slf4j-api-1.7.5.jar

slf4j-log4j12-1.7.5.jar

创建数据库mybatis 数据建表items;和插入测试数据：

CREATE DATABASE mybatis DEFAULT CHARACTER SET utf8 ;

USE mybatis;

DROP TABLE IF EXISTS items;

CREATE TABLE items (

id INT(11) NOT NULL AUTO_INCREMENT,

NAME VARCHAR(32) NOT NULL COMMENT '商品名称', --COMMENT '商品名称'设置字段描述

price FLOAT(10,1) NOT NULL COMMENT '商品定价',

detail TEXT COMMENT '商品描述',

pic VARCHAR(64) DEFAULT NULL COMMENT '商品图片',

createtime DATETIME NOT NULL COMMENT '生产日期',

PRIMARY KEY (`id`)

) ENGINE=INNODB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

/*Data for the table `items` */

INSERT INTO items(`id`,`name`,`price`,`detail`,`pic`,`createtime`) VALUES

(1,'台式机',3000.0,'该电脑质量非常好！！！！',NULL,'2015-02-03 13:22:53'),

(2,'笔记本',6000.0,'笔记本性能好，质量好！！！！！',NULL,'2015-02-09 13:22:57'),

(3,'背包',200.0,'名牌背包，容量大质量好！！！！',NULL,'2015-02-06 13:23:02');

===============源码=======================

--------(1:)写PO类 Items.java

package cn.ssm.po;

import java.util.Date;

public class Items {

private Integer id;

private String name;

private Float price;

private String pic;

private Date createtime;

private String detail;

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name == null ? null : name.trim();

}

public Float getPrice() {

return price;

}

public void setPrice(Float price) {

this.price = price;

}

public String getPic() {

return pic;

}

public void setPic(String pic) {

this.pic = pic == null ? null : pic.trim();

}

public Date getCreatetime() {

return createtime;

}

public void setCreatetime(Date createtime) {

this.createtime = createtime;

}

public String getDetail() {

return detail;

}

public void setDetail(String detail) {

this.detail = detail == null ? null : detail.trim();

/* if(detail == null)

{

this.detail = null;

}else{

this.detail = detail.trim();

}*/

}

}

(2)======mybatis======>使用的是Mapper代理<=======================

说明：a:ItemsMapper.java 和 ItemsMapper.xml名字相同：后缀不一样

b:ItemsMapper.xml的命名空间为所在包名cn.ssm.mapper.ItemsMapper

c:ItemsMapper.java 和 ItemsMapper.xml在同一包下

d:ItemsMapper.java的方法名和ItemsMapper.xml对应sql语句名称一致

以上条件缺一出现如下异常

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

cn.ssm.mapper.ItemsMapper.findItemsList

// 返回ModelAndView

// 相当于request的setAttribut，在jsp页面中通过itemsList取数据

// 指定视图

// 下边的路径，如果在视图解析器中配置jsp路径的前缀和jsp路径的后缀，修改为

// modelAndView.setViewName("/WEB-INF/jsp/items/itemsList.jsp");

// 上边的路径配置可以不在程序中指定jsp路径的前缀和jsp路径的后缀
