SSM框架系列学习总结0之IDEA+Maven+SSM整合

这是我系列总结的最后一篇, 终于弄完了!
虽然有点累, 但是很充实, 很开心, 送一张图片给自己, 哈哈!

使用IDEA和Maven创建Java Web项目

下面演示直接截图:

创建Maven项目时, 这里需要加入一个参数, 否则后面会创建失败:
Properties:
archetypeCatalog=internal

创建成功:

然后配置Tomcat服务器, 注意创建的时候选择本地的.

运行成功:

Github与IntelliJ IDEA整合

参考: http://www.cnblogs.com/MrJun/p/3351478.html

配置Maven依赖

在pom.xml中加入:

Spring各模块配置

首先配置Mybatis的全局配置文件 sqlMapConfig.xml:

<configuration> 
    

    
    <typeAliases>
        <package name="com.wtu.model"/>
    typeAliases>
configuration>

spring-mapper.xml:

<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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

    
    <context:property-placeholder location="classpath:jdbc.properties"/>

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${driver}"/>
        <property name="jdbcUrl" value="${url}"/>
        <property name="user" value="${user}"/>
        <property name="password" value="${password}"/>
    bean>

    
    <bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis/sqlMapConfig.xml"/>
        
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    bean>

    
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.wtu.dao"/>
        
        <property name="sqlSessionFactoryBeanName" value="factory"/>
    bean>
beans>

数据库连接配置的属性文件 jdbc.properties:

driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///ssm-demo
user=root
password=lxy

Spring配置service层

spring-service.xml

<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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

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

    
    <tx:advice id="tx_advice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*"/>
        tx:attributes>
    tx:advice>

    
    <aop:config proxy-target-class="true">
        <aop:pointcut id="xxx"
                      expression="execution(* com.wtu.service.impl.UserServiceImpl.*(..))"/>
        <aop:advisor advice-ref="tx_advice" pointcut-ref="xxx"/>
    aop:config>

    
    <context:annotation-config/>

    
    <context:component-scan base-package="com.wtu.service"/>
beans>

然后配置log4j:
直接在类路径下添加log4j.properties:

#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-Demo.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

建表的SQL语句

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,  
  `user_name` varchar(40) NOT NULL,  
  `password` varchar(255) NOT NULL,  
  `age` int(4) NOT NULL,  
  PRIMARY KEY (`id`)  
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;  

/* Data for the table `user` */

insert  into `user`(`id`,`user_name`,`password`,`age`) values (1,'小阳','666',21);

SSM框架——使用MyBatis Generator自动创建代码

最后配置springmvc.xml和web.xml

springmvc.xml:

<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"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"

    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd 
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

    
    
    <context:component-scan base-package="com.wtu.controller"/>

    
    <mvc:annotation-driven />

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        
        <property name="prefix" value="/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>

web.xml:

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

Controller中的方法:

/**
 * User类的控制器, 视图显示
 *
 * menglanyingfei
 * on 2017.11.02 17:34
 */

@Controller
@RequestMapping("/user")
public class UserController {
    @Resource
    private UserService userService;

    @RequestMapping("/showUser")
    public String toIndex(HttpServletRequest request, Model model) {
        // 应该这样输入/user/showUser?id=1
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = userService.getUserById(userId);
        model.addAttribute("user", user);
        return "/showUser";

//        return "forward:/jsp/showUser.jsp";
    }

    @RequestMapping("/showUser1")
    public ModelAndView home(HttpServletRequest request, Model model) {
        // 应该这样输入/user/showUser1?id=1
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = userService.getUserById(userId);
        model.addAttribute("user", user);

        ModelAndView mav = new ModelAndView();

        mav.setViewName("/showUser");

        return mav;
    }
}

然后在浏览器输入
http://localhost:8080/项目名/user/showUser1?id=1
