Spring与Mybatis整合


1.建立jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/sampledb
username=root
password=123456
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

2.建立spring-mybatis.xml


<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:cache="http://www.springframework.org/schema/cache" xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
     http://www.springframework.org/schema/aop
     http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
     http://www.springframework.org/schema/context

     http://www.springframework.org/schema/tx
     http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
     http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd">

    
    <context:component-scan base-package="cn.ly.ssm" />
    
    <bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties" />
    bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${driver}" />
        <property name="url" value="${url}" />
        <property name="username" value="${username}" />
        <property name="password" value="${password}" />
        
        <property name="initialSize" value="${initialSize}">property>
        
        <property name="maxActive" value="${maxActive}">property>
        
        <property name="maxIdle" value="${maxIdle}">property>
        
        <property name="minIdle" value="${minIdle}">property>
        
        <property name="maxWait" value="${maxWait}">property>
    bean>

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        
        <property name="mapperLocations" value="classpath:cn/ly/ssm/mapping/*.xml">property>
    bean>

    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.ly.ssm.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">property>
    bean>

    
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    bean>

3.Log4j的配置

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式,下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

4.利用MyBatisGenerator自动创建代码

整合spring mvc


1.配置spring-mvc.xml


<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    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-4.0.xsd  
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


    
    <context:component-scan base-package="cn.ly.ssm.controller" />

    
    <mvc:annotation-driven />

    
    
    
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    bean>

    
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        
        <property name="defaultEncoding" value="utf-8" />
        
        <property name="maxUploadSize" value="10485760000" />
        
        <property name="maxInMemorySize" value="40960" />
    bean>


beans>

2.配置web.xml文件


<web-app id="WebApp_ID" version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <display-name>Archetype Created Web Applicationdisplay-name>
    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:spring-mybatis.xmlparam-value>
    context-param>
    
    <filter>
        <filter-name>encodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <async-supported>trueasync-supported>

    <filter-mapping>
        <filter-name>encodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>
    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListenerlistener-class>

    <servlet>

        <init-param>

        init-param>
        <load-on-startup>1load-on-startup>

    servlet-mapping>
    <welcome-file-list>
        <welcome-file>/index.jspwelcome-file>
    welcome-file-list>
web-app>

3.新建jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<html>
  <head>
  <title>测试title>
  head>

  <body>
   ${user.userName}
  body>
html>

4.建立UserController类

package cn.ly.ssm.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.ly.ssm.model.User;
import cn.ly.ssm.service.IUserService;

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private IUserService userService;

    @RequestMapping("/showUser")
    public String toIndex(HttpServletRequest request,Model model){
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = this.userService.getUserById(userId);
        model.addAttribute("user", user);
        return "showUser";
    }
}
