话不多说.如下图显示,idea的结构

idea+maven+ssm整合随手案例

由上至下给大家分享一下SSM整合的一个流程,首先配置maven中的pom文件加载jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

 <build>
        <finalName>springmvc</finalName>
    </build>
</project>

这里把注释打开即可使用

首先是配置文件jdbc.propertis

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/a?characterEncoding=utf-8   连接数据库改为自己的
jdbc.username=root
jdbc.password=root   这里密码改为自己的密码

接下来就是日志文件 log4j.properties,这里不需要做改动,直接copy即可

### set log levels ###
log4j.rootLogger = info , Console , D
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=INFO
log4j.logger.java.sql.Statement=INFO
log4j.logger.java.sql.PreparedStatement=INFO
#output2file
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = D\:/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO \#\# \u00E8\u00BE\u0093\u00E5\u0087\u00BAinfo\u00E7\u00BA\u00A7\u00E5\u0088\u00A\
  B\u00E4\u00BB\u00A5\u00E4\u00B8\u008A\u00E7\u009A\u0084\u00E6\u0097\u00A5\u00E5\u00BF\u0097
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH\:mm\:ss} [ %t\:%r ] - [ %p ] %m%n
接下来是SqlMapConfig.xml这个文件,不整合前有用,整合之后里面也没东西了 

<?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>

</configuration>

接下来就是重点了spring和mbatis的整合spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
   http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
   http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
   http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">

    <context:property-placeholder location="classpath:config/jdbc.properties" /> 
    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          destroy-method="close">
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="maxActive" value="10" />
        <property name="minIdle" value="5" />
    </bean>
    <!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 加载mybatis的全局配置文件 -->
        <property name="configLocation" value="classpath:config/SqlMapConfig.xml" />
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.yanlei.mapper" />  改成自己的文件包名
    </bean>

    <!--
           4. 事务管理 : DataSourceTransactionManager dataSource:引用上面定义的数据源
       -->
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!-- 5. 使用声明式事务
         transaction-manager：引用上面定义的事务管理器
     -->
    <tx:annotation-driven transaction-manager="transactionManager" />

</beans>

接下来是spring和mvc的整合 spring-mvc.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:p="http://www.springframework.org/schema/p"
       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-4.2.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <context:component-scan base-package="com.yanlei.controller"/> 改成自己的文件包名

    <mvc:annotation-driven/>
    <mvc:default-servlet-handler />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/html/"/>
        <property name="suffix" value=".html"/>
    </bean>
    
    <!-- 文件上传配置 -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 默认编码 -->
        <property name="defaultEncoding" value="UTF-8"/>
        <!-- 上传文件大小限制为31M ,31*1024*1024 -->
        <property name="maxUploadSize" value="32505856"/>
        <!-- 内存中最大值 -->
        <property name="maxInMemorySize" value="4096"/>
    </bean>
</beans>

接下来就是web.xml的配置加载,这里是配置文件的加载是有顺序的(注意!)

<!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>

    <!--加载配置文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/spring-mybatis.xml</param-value>
    </context-param>
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:/config/log4j.properties</param-value>
    </context-param>

    <!--编码过滤器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>spring-mvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring-mvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

配置完了就到了测试阶段了

package com.yanlei.controller;

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

@Controller
public class Test {

    @RequestMapping(value = "/")
    public String showIndex(){
        return "/index";
    }
}

HTML如下


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <title>Title</title>
</head>
<body>
<h3>123456</h3>
</body>
</html>


测试结果如下图显示,完美结束.
