  1. 主要三个配置文件分别对应spring-mvc.xml、spring-service、spring-mybatis.xml,三个文件分别管理控制层action、服务层service和数据库持久层dao，三个配置如下：

spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
    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.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-3.0.xsd">
    <!-- 扫描action相关的bean -->
    <context:component-scan base-package="com.sven.ssm.action" />
    <mvc:annotation-driven />
    
    <!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理：js,gif,png (2)允许使用"/"做整体映射 -->
    <mvc:default-servlet-handler/>
    
    <!-- 3.配置jsp 显示ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/" />
        <property name="suffix" value=".html" />
    </bean>
</beans>

spring-service.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:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!-- 扫描service包下所有使用注解的类型 -->
    <context:component-scan base-package="com.sven.ssm.service" />

    <!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 配置基于注解的声明式事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
   <import resource="classpath:spring-mybatis.xml" />
</beans>

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:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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">
    <!-- 配置整合mybatis过程 -->
    <!-- 1.配置数据库相关参数properties的属性：${url} -->
    <context:property-placeholder location="classpath:jdbc.properties" />
    
    <!-- 2.数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!-- 初始化连接大小 -->
        <property name="initialSize" value="${initialSize}"/>
        <!-- 连接池最大数量 -->
        <property name="maxActive" value="${maxActive}"/>
        <!-- 连接池最大空闲 -->
        <property name="maxIdle" value="${maxIdle}"/>
        <!-- 连接池最小空闲 -->
        <property name="minIdle" value="${minIdle}"/>
        <!-- 获取连接最大等待时间 -->
        <property name="maxWait" value="${maxWait}"/>
    </bean>
    
    <!-- 3.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 配置MyBaties全局配置文件:classpath:SqlMapConfig.xml -->
        <property name="configLocation" value="classpath:SqlMapConfig.xml" />
        <!-- 扫描entity包 使用别名 -->
        <property name="typeAliasesPackage" value="com.sven.ssm.dao.domain" />
        <!-- 扫描sql配置文件:mapper需要的xml文件 -->
        <property name="mapperLocations" value="classpath:com/sven/ssm/mapper/*.xml" />
    </bean>
    
    <!-- 4.配置扫描Dao接口包，动态实现Dao接口，注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.sven.ssm.dao" />
    </bean>
</beans>

2.配置需要的属性文件jdbc.properties和次要配置文件SqlMapConfig.xml

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/db_springsecurity_ssm
jdbc.username=root
jdbc.password=root12345
#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

SqlMapConfig (什么都没有配置)

<?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>
  1. 然后配置web.xml的文件（主要通过servlet加载三个配置文件）

web.xml

<web-app metadata-complete="true"
    version="3.1"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
    
        <!-- Spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 防止Spring内存溢出监听器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>
    <!-- 配置DispatcherServlet -->
    <!-- 编码过滤器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <async-supported>true</async-supported>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 配置springMVC需要加载的配置文件 spring-dao.xml,spring-service.xml,spring-web.xml Mybatis
            - > spring -> springmvc -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>  
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <!-- 默认匹配所有的请求 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    
    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>
    
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

  1. 至于pom配置文件就不介绍了（网上好多，随便copy过来）

  2. 整合slf4j（主要就是加了一个依赖slf4j）如下：

<!-- 日志处理 -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.21</version>
        </dependency>

然后使用的话就如下使用

TestAction

package com.sven.ssm.action;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/test")
public class TestAction
{
    private Logger logger = LoggerFactory.getLogger(TestAction.class);
    @RequestMapping("/index")
    public String index(){
        logger.info("test");
        System.out.println("test");
        return "hello world";
    }
}

然后向配置一些特殊的个性化就在resource目录下加一个log4j.properties配置文件

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

log4j.appender.File.DatePattern=yyyy-MM-dd'.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
  1. 整合freemarker
    添加freemarker的依赖
              <!-- freemarker -->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>${freemarker.version}</version>
        </dependency>

然后在spring-mvc中添加freemarker相关的配置

spring-service.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:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!-- 扫描service包下所有使用注解的类型 -->
    <context:component-scan base-package="com.sven.ssm.service" />

    <!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 配置基于注解的声明式事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" /><bean id="freeMarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/pages/" />
        <property name="freemarkerSettings">
            <props>
                <prop key="template_update_delay">1</prop>
                <prop key="locale">zh_CN</prop>
                <prop key="datetime_format">yyyy-MM-dd</prop>
                <!-- 时间格式化 -->
                <prop key="date_format">yyyy-MM-dd</prop>
                <prop key="number_format">#.##</prop>
            </props>
        </property>
    </bean>
    
<!--    <bean id="freemarkerConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:freemarker.properties"></property>
    </bean> -->
    
    <bean id="freeMarkerViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="cache" value="true" />
        <property name="suffix" value=".html" />        
        <property name="contentType" value="text/html;charset=UTF-8" />
<!--        <property name="allowSessionOverride" value="true" />
        <property name="allowRequestOverride" value="true" />
        <property name="exposeSpringMacroHelpers" value="true" />
        <property name="exposeRequestAttributes" value="true" />
        <property name="exposeSessionAttributes" value="true" />
        <property name="requestContextAttribute" value="request" /> -->
    </bean>
    
    
</beans>

然后在控制器中如下使用

TestAction

package com.sven.ssm.action;

import java.io.UnsupportedEncodingException;
import java.util.ArrayList;
import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import com.sven.ssm.domain.User;

@RestController
@RequestMapping("/test")
public class TestAction
{
    private Logger logger = LoggerFactory.getLogger(TestAction.class);
    @RequestMapping("/index")
    public String index(){
        logger.info("test");
        System.out.println("test");
        return "hello world";
    }
    
    @RequestMapping(value="/test")
    @ResponseBody
    public ModelAndView test(@RequestParam(value = "a", required = false) String a) throws UnsupportedEncodingException{
        ModelAndView mv = new ModelAndView();
        User user = new User("may", 21);
        List<String> list = new ArrayList<String>();
        list.add("Jack1");
        list.add("Jack2");
        list.add("Jack3");
        mv.addObject("list", list);
        mv.addObject("user", user);
        mv.addObject("param", new String(a.getBytes("iso8859-1"), "utf-8"));
        mv.setViewName("test");
        return mv;
    }
}
