Spring + SpringMVC + Mybatis整合流程

1      需求

1.1     客户列表查询

1.2     根据客户姓名模糊查询

2      整合思路

第一步：整合dao层

Mybatis和spring整合，通过spring管理mapper接口，使用mapper扫描器自动扫描mapper接口，并在spring中进行注册。

第二步：整合service层

通过spring管理service层，service调用mapper接口。使用配置方式将service接口配置在spring配置文件中，并且进行事务控制。

第三步：整合springMVC

由于springMVC是spring的模块，不需要整合。

3      准备环境

3.1     数据库版本

mysql5.7

3.2

编译器

eclipse

3.3

Jar 包

3.3.1

spring的jar包

3.3.2

3.3.3

mybatis的jar包

3.3.4

数据库驱动包

3.3.5

log4j包

3.3.6

log4j配置文件

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target=System.err

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=debug, stdout

3.3.7     dbcp数据库连接池包

3.3.8     jstl包

4      整合dao

4.1      sqlMapconfig.xml

mybatis的配置文件：

/p>

PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

4.2      db.properties数据库配置文件

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/haohan1?characterEncoding=utf8&useSSL=false

jdbc.username=root

jdbc.password=123456

4.3     applicationContext-dao.xml

spring在这个xml文件中配置dbcp连接池，sqlSessionFactory，mapper的批量扫描。

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/aop

http://www.springframework.org/schema/aop/spring-aop.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd">

4.4     逆向工程生成po类和mapper接口和mapper.xml文件

生成如下图的文件：

4.5     自定义mapper接口和xml文件，以及po的包装类

4.5.1     CustomMapper.java

public interfaceCustomMapper {public List findAllCustom(HhCustomVo hhCustomVo)throwsException;

}

4.5.1     CustomMapper.xml

/p>

PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

name like '%${hhCustom.name}%'

SELECT

* FROM hh_custom

4.5.2     HhCustomVo

//客户的包装类

public classHhCustomVo {//客户信息

privateHhCustom hhCustom;publicHhCustom getHhCustom() {returnhhCustom;

}public voidsetHhCustom(HhCustom hhCustom) {this.hhCustom =hhCustom;

}

}

4.6     数据库表结构

5      整合service

5.1     定义service接口

public interfaceCustomService {public HhCustom findCustomById(Integer id)throwsException;public List findAllCustom(HhCustomVo hhCustomVo)throwsException;

}

5.2     service接口实现

public class CustomServiceImpl implementsCustomService{

@Autowired

HhCustomMapper hhCustomMapper;

@Autowired

CustomMapper customMapper;

@Overridepublic HhCustom findCustomById(Integer id) throwsException {//TODO Auto-generated method stub

returnhhCustomMapper.selectByPrimaryKey(id);

}

@Overridepublic List findAllCustom(HhCustomVo hhCustomVo) throwsException {//TODO Auto-generated method stub

returncustomMapper.findAllCustom(hhCustomVo);

}

}

5.3     在spring容器配置service(applicationContext-service)

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/aop

http://www.springframework.org/schema/aop/spring-aop.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd">

5.4   事务控制(applicationContext-transaction)

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/aop

http://www.springframework.org/schema/aop/spring-aop.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd">

6      整合springMVC

6.1      springmvc.xml

在springmvc.xml中配置适配器映射器、适配器处理器、视图解析器

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/aop

http://www.springframework.org/schema/aop/spring-aop.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc.xsd">

6.2     配置前端控制器(web.xml)

springmvc

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath:spring/springmvc.xml

springmvc

*.action

6.3     编写controller

@Controllerpublic classCustomController {

@Autowired

CustomService customService;//模糊查询客户

@RequestMapping("/findAllCustom")public ModelAndView findAllCustom(HhCustomVo hhCustomVo) throwsException {

List customlist =customService.findAllCustom(hhCustomVo);

ModelAndView modelAndView= newModelAndView();

modelAndView.addObject("customlist", customlist);

modelAndView.setViewName("customlist");returnmodelAndView;

}//根据客户id查询

public ModelAndView findCustomByid(Integer id) throwsException {

HhCustom hhCustom=customService.findCustomById(id);

ModelAndView modelAndView= newModelAndView();

modelAndView.addObject("hhCustom", hhCustom);

modelAndView.setViewName("customlist");returnmodelAndView;

}

}

6.4     编写jsp

客戶列表

查询条件：

客戶名称：

客戶类型：

${customType.value}

--%>

查询

客戶列表：

选择客戶名称客戶邮箱客戶电话客户类型${custom.name }${custom.mail }${custom.phoneNumber }${custom.category }修改 --%>

7      加载spring容器(web.xml)

contextConfigLocation

classpath:spring/applicationContext-*.xml

org.springframework.web.context.ContextLoaderListener

8      Post方法中文乱码(web.xml)

CharacterEncodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

UTF-8

CharacterEncodingFilter

/*

9      结果

9.1     客户查询列表

9.2     根据模糊
