SpringMVC4 + MyBatis3 + SQL Server 2014整合教程（含增删改查分页）

前言

说起整合自然离不开ssm，我本身并不太喜欢ORM,尤其是MyBatis，把SQL语句写在xml里，尤其是大SQL，可读性不高，出错也不容易排查。

开发环境

idea2016、SpringMVC4、Mybatis3

项目结构

SSM整合

1、pom.xml

2、web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
 <display-name>Archetype Created Web Application</display-name>
 <!--告知javaEE容器，有那些内容需要添加到上下文里去-->
 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath:applicationContext.xml</param-value>
 </context-param>
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
 <!--spring 前端控制器-->
 <servlet>
 <servlet-name>SpringMVC</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <init-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:springmvc-servlet.xml</param-value>
 </init-param>
 </servlet>
 <servlet-mapping>
 <servlet-name>SpringMVC</servlet-name>
 <url-pattern>/</url-pattern>
 </servlet-mapping>
</web-app>

3、applicationContext.xml无配置内容所以忽略

4、springmvc-servlet.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:mvc="http://www.springframework.org/schema/mvc"
  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.xsd
  http://www.springframework.org/schema/mvc
  http://www.springframework.org/schema/mvc/spring-mvc.xsd
">

 <!--从配置文件加载数据库信息-->
 <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="locations" value="classpath:config/jdbc.properties"/>
  <property name="fileEncoding" value="UTF-8"/>
 </bean>

 <!--配置数据源，这里使用Spring默认-->
 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName" value="${sqlserver.driver}"/>
  <property name="url" value="${sqlserver.url}"/>
  <property name="username" value="${sqlserver.username}"/>
  <property name="password" value="${sqlserver.password}"/>
 </bean>

 <!--扫描Mapper-->
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  <property name="basePackage" value="com.autohome.mapper"/>

 </bean>

 <!--配置sqlSessionFactory-->
 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  <property name="configLocation" value="classpath:springmvc-mybatis.xml"/>
  <property name="dataSource" ref="dataSource"/>
 </bean>

 <!--启用最新的注解器、映射器-->
 <mvc:annotation-driven/>

 <!--扫描Controller注解类-->
 <context:component-scan base-package="com.autohome.controller" />
 <!--扫描Service注解类-->
 <context:component-scan base-package="com.autohome.service"/>

 <!--配置视图解析器-->
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix" value="/WEB-INF/views/"/>
  <property name="suffix" value=".jsp"/>
 </bean>

</beans>

5、springmvc-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

 <!-- 实体类,简称 -设置别名 -->
 <typeAliases>
  <typeAlias alias="User" type="com.autohome.model.User" />
 </typeAliases>


 <mappers>
  <mapper resource="mapper/UserMapper.xml" />
 </mappers>

</configuration>

6、dao接口层、mapper（dao接口实现层）、Biz层、 model层忽略不计(id,name,address3个测试字段)。 mapper文件让我踩了坑，后恍然大悟，mapper.xml要放在resources包下。

public interface UserMapper {

 List<User> listAllUser();

 List<User> listPagedUser(@Param("pageIndex") int pageIndex,@Param("pageSize") int pageSize);

 int count();

 int updateUser(User user);

 int deleteUser(int id);

 int insertUser(User user);

 User getUserById(int id);

 

}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--命名空间和接口保持一致-->
<mapper namespace="com.autohome.mapper.UserMapper">
 <select id="listAllUser" resultType="User">
  select * from t_userinfo
 </select>

 <select id="listPagedUser" resultType="User">
  select top ${pageSize} * from t_userinfo where id not in (select top (${pageSize} * (${pageIndex} -1)) id from t_userinfo)
 </select>

 <select id="count" resultType="int">
  select count(*) from t_userinfo
 </select>

 <insert id="insertUser" parameterType="User">
  insert into t_userinfo VALUES (#{name},#{address})
 </insert>

 <update id="updateUser" parameterType="User">
  UPDATE t_userinfo set name=#{name},address=#{address} where id=#{id}
 </update>

 <delete id="deleteUser" parameterType="int">
  DELETE FROM t_userinfo where id=#{id}
 </delete>

 <select id="getUserById" resultType="User" parameterType="int">
  select * from t_userinfo where id=#{id}
 </select>

</mapper>

public interface IUserBiz {

 List<User> listAllUser();

 List<User> listPagedUser(@Param("pageIndex") int pageIndex, @Param("pageSize") int pageSize);

 int count();

 int updateUser(User user);

 int deleteUser(int id);

 int insertUser(User user);

 User getUserById(int id);

}

package com.autohome.service;

 

import com.autohome.model.User;

import com.autohome.mapper.UserMapper;

import org.apache.ibatis.annotations.Param;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

 

import java.util.List;

import java.util.Map;

 

 

@Service

public class UserBizImpl implements IUserBiz {

 

 @Autowired

 private UserMapper userMapper;

 

 public List<User> listAllUser() {

  return userMapper.listAllUser();

 }

 

 public List<User> listPagedUser(@Param("pageIndex") int pageIndex,@Param("pageSize") int pageSize) {

  return userMapper.listPagedUser(pageIndex,pageSize);

 }

 

 public int count() {

  return userMapper.count();

 }

 

 public int updateUser(User user) {

  return userMapper.updateUser(user);

 }

 

 public int deleteUser(int id) {

  return userMapper.deleteUser(id);

 }

 

 public int insertUser(User user) {

  return userMapper.insertUser(user);

 }

 

 public User getUserById(int id) {

  return userMapper.getUserById(id);

 }

}

7、Controller。我新建了一个UserController，在这里调用了增删改查分页的操作

package com.autohome.controller;

 

import com.autohome.service.IUserBiz;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

 

import com.autohome.model.User;

 

 

@Controller

@RequestMapping("/User")

public class UserController {

 

 @Autowired

 private IUserBiz userBiz;

 

 @RequestMapping("/index")

 public ModelAndView index(){

  //System.out.println("size:"+userBiz.listAllUser().size());

 

  System.out.println("size:"+userBiz.count());

//

//  User user =new User();

//  user.setName("张三");

//  user.setAddress("shanxi");

//

//  int result = userBiz.insertUser(user);

//  if(result>0)

//  {

//   System.out.println("insert success");

//  }else{

//   System.out.println("insert err");

//  }

 

  int result = userBiz.deleteUser(39);

  if(result>0)

  {

   System.out.println("delete success");

  }else{

   System.out.println("delete err");

  }

 

//  User user =new User();

//  user.setId(35);

//  user.setName("张三11111");

//  user.setAddress("china");

//

//  int result = userBiz.updateUser(user);

//  if(result>0)

//  {

//   System.out.println("update success");

//  }else{

//   System.out.println("update err");

//  }

 

 

  //System.out.println("size:"+userBiz.listPagedUser(1,10).size());

 

 

 

  ModelAndView mav=new ModelAndView("index");

 

  return mav;

 }

}

总结

做这个demo前我看的ssm整合教程全部是基于myeclipse开发的，而且教程把dao接口和dao实现是全部放在src java目录下的，也就是mapper目录包括了mapper接口和mapper.xml。我做第一个demo时在idea里也是这么做的，demo运行始终不成功，一直提示找不到mapper.xml里的方法，后来编译的时候我发现target/classes里确实找不到mapper.xml。不知道用myeclipse整合开发时是否遇到这个问题，后我把mapper.xml文件放到resources目录中，编译后target文件总就能找到mapper.xml。方法运行也搞定了。写demo写了半个小时，debug这个问题花了2个小时，好在demo跑起来了，也算是有收获的。

好了，以上就是这篇文章的全部内容了，希望本文的内容对大家的学习或者工作能带来一定的帮助，如果有疑问大家可以留言交流，谢谢大家对的支持。
