            <version>${jackson.version}</version>

        </dependency>

    </dependencies>

</project>

三、配置springMVC

在resources文件夹下建立spring-mvc.xml,如下图

具体内部配置如下：

<?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:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

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

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd

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

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

    <!-- 自动扫描该包，使用SpringMVC认为包下用了@Controller注解的类是控制器,避免扫描@Service导致事务不能使用 -->

    <context:component-scan base-package = "fv">

        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>

    </context:component-scan>

    <!--避免IE执行AJAX时，返回JSON出现下载文件 -->

    <bean id = "mappingJacksonHttpMessageConverter"

          class = "org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

        <property name = "supportedMediaTypes">

            <list>

                <value>text/html;charset=UTF-8</value>

            </list>

        </property>

    </bean>

    <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->

    <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">

        <property name="order" value="1"/>

        <property name="defaultViews">

            <list>

                <!-- JSON View -->

                <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">

                </bean>

            </list>

        </property>

    </bean>

    <!-- 定义跳转的文件的前后缀 ，视图模式配置-->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <!-- 自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->

        <property name="prefix" value="/WEB-INF/page/" />

        <property name="suffix" value=".jsp" />

        <!-- <property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/>   -->

    </bean>

    <!-- 文件上传 -->

    <!-- <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <property name="maxUploadSize" value="102400000"></property>

    </bean> -->

   <!-- <mvc:interceptors>

        <mvc:interceptor>

            <mvc:mapping path="/mvc/**"/>

            <bean class="test.SpringMVC.Interceptor.MyInterceptor"></bean>

        </mvc:interceptor>

    </mvc:interceptors> -->

    <!-- 添加后可以显示welcome-file界面 -->

    <mvc:default-servlet-handler/>

    <!-- 启动注解 -->

    <mvc:annotation-driven />

</beans>

四、整合mybatis

在resource文件夹下建立spring-mybatis.xml文件夹，配置内容如下：

<?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-3.1.xsd

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

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd

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

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

    <!-- 自动扫描 -->

    <context:component-scan base-package="fv">

        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

    </context:component-scan>

    <!-- 引入数据库配置文件 -->

    <bean id = "propertyConfigurer"

          class = "org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">

        <property name = "location" value="classpath:jdbc.properties" />

    </bean>

    <!-- 连接池 -->

    <bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource"

          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="${jdbc.initialSize}" />

        <!-- 连接池最大数量 -->

        <property name="maxActive" value="${jdbc.maxActive}"/>

        <!-- 连接池最大空闲 -->

        <property name="maxIdle" value="${jdbc.maxIdle}" />

        <!-- 连接池最小空闲 -->

        <property name="minIdle" value="${jdbc.minIdle}" />

        <!-- 获取连接最大等待时间 -->

        <property name="maxWait" value="${jdbc.maxWait}" />

    </bean>

    <!-- 结合Spring和Mybatis -->

    <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dataSource" />

        <!-- 自动扫描mapping.xml文件 -->

        <property name = "mapperLocations" value="classpath:fv/mapping/*.xml" />

    </bean>

    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->

    <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name = "basePackage" value="fv.dao" />

        <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" />

    </bean>

    <!-- 定义事务 -->

    <bean id = "transactionManager"

          class = "org.springframework.jdbc.datasource.DataSourceTransactionManager">

        <property name = "dataSource" ref = "dataSource" />

    </bean>

    <!-- 使用注解定义事务 -->

    <tx:annotation-driven transaction-manager = "transactionManager" />

</beans>

　五、配置属性文件

在此总共有两个属性文件，一个是log4j.properties,另一哥是数据库连接文件jdbc.properties;

log4j.properties文件内容如下：

#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

jdbc.properties文件如下:

jdbc.driver=oracle.jdbc.driver.OracleDriver

jdbc.url=jdbc:oracle:thin:@192.168.1.213:1521:orcl

jdbc.username=KYYS

jdbc.password=kyys

#定义初始连接数

jdbc.initialSize=0

#定义最大连接数

jdbc.maxActive=20

#定义最大空闲

jdbc.maxIdle=20

#定义最小空闲

jdbc.minIdle=1

#定义最长等待时间

jdbc.maxWait=60000

　在webapp/WEB-INF/下web.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<web-app 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"

         version="3.1">

    <display-name>Archetype Created Web Application</display-name>

    <!-- Spring和Mybatis的配置文件 -->

    <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:spring-mybatis.xml</param-value>

    </context-param>

    <!-- 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-</param-value>

        </init-param>

    </filter>

    <filter-mapping>

        <filter-name>encodingFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- configure the HiddenHttpMethodFilter,convert the post method to put or delete -->

  <!-- <filter>

      <filter-name>HiddenHttpMethodFilter</filter-name>

      <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

  </filter>

  <filter-mapping>

      <filter-name>HiddenHttpMethodFilter</filter-name>

      <url-pattern>/*</url-pattern>

  </filter-mapping> -->

    <!-- 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>

    <!-- Spring MVC servlet -->

    <servlet>

        <servlet-name>SpringMVC</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>classpath:spring-mvc.xml</param-value>

        </init-param>

        <!-- 容器在启动时就加载这个servlet -->

        <load-on-startup>1</load-on-startup>

        <async-supported>true</async-supported>

    </servlet>

    <servlet-mapping>

        <servlet-name>SpringMVC</servlet-name>

        <url-pattern>/</url-pattern>

    </servlet-mapping>

   <!--  设置默认首页 -->

    <welcome-file-list>

        <welcome-file>/index.jsp</welcome-file>

    </welcome-file-list> 

</web-app>

六、程序内容

程序目录结构如下如：

index.jsp页面内容：

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

测试框架<a href="test/index"  method ="POST">登录</a>

    <form action= "test/indexPost" method ="POST">

           <input type= "submit" value ="测试登录"/>

     </form >

     <form action= "home/gohome" >

           <input type= "text" id="id" name="id" value ="0"/>

           <input type= "submit" value ="测试登录"/>

     </form >

     <form action= "home/index" >

           <input type= "submit" value ="测试登录"/>

     </form >

</body>

</html>

　　Controller控制器

package fv.controller;

import org.springframework.stereotype.Controller;

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

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.bind.annotation.ResponseBody;

@Controller

@RequestMapping(value = "/home")

public class HomeController {

	@RequestMapping(value = "/gohome", method = RequestMethod.GET)

    @ResponseBody

    public String  goToHome(@RequestParam("id") String id) {

        return "this is my home";//Integer.parseInt(id)

    }

	@RequestMapping(value = "/index",method = RequestMethod.GET)

    public String index()

    {

    	return "/admin";

    }

}

package fv.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.stereotype.Controller;

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

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.bind.annotation.ResponseBody;

import fv.Service.TestService;

@Controller

@RequestMapping("/test")

public class TestController {

	    //@Autowired

	    private TestService testServiceImp;//    

	    @RequestMapping(value = "/get", method = RequestMethod.GET)

	    @ResponseBody

	    public String  getTestByName(@RequestParam("id") String id) {

	        return testServiceImp.getByName(0L);//Integer.parseInt(id)

	    }

	    @RequestMapping(value = "/hello", method = RequestMethod.GET)

	    @ResponseBody

	    public String  HellowWorld(@RequestParam("id") String id) {

	        return "Hello World";//Integer.parseInt(id)

	    }

	    @RequestMapping(value = "/index",method = RequestMethod.GET)

	    public String index()

	    {

	    	return "/admin";

	    }

	    @RequestMapping(value = "/indexPost")

	    public String indexPost()

	    {

	    	return "/admin";

	    }

}

　dao层Mapper接口：

package fv.dao;

public interface HomeMapper {

	String getByName(Long id);

}

package fv.dao;

public interface TestMapper {

	 String getByName(Long id);

}
