SSM三大框架整合：

目的：使用SSM将数据库的所有信息显示在jsp页面，成功证明SSM环境搭配成功。
前戏：导入32个包、建立config的source folder文件夹、里面有四个文件
1、在web.xml里面配置：

<!-- 配置监听器，上下文加载监听器 -->
<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 指明applicationContext.xml文件位置 -->
<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<!-- 配置spring自带的字符编码过滤器 -->
<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>
</filter>
<filter-mapping>
	<filter-name>encodingFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 配置springmvc核心 -->
<servlet>
	<servlet-name>springmvc</servlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class>
	<!-- 因为springmvc的配置文件不在默认位置，所以要指明 -->
	<init-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:springmvc-servlet.xml</param-value>
	</init-param>
</servlet>
<servlet-mapping>
	<servlet-name>springmvc</servlet-name>
	<url-pattern>/</url-pattern>
</servlet-mapping>

2、在applicationContext.xml里面配置：

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

<!-- 引入外部数据库连接 -->
<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

	<property name="username" value="${jdbc.username}"></property>
	<property name="password" value="${jdbc.password}"></property>
</bean>

<!-- 配置事务管理器 -->

</bean>

<!-- 配置mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	<property name="basePackage" value="com.officn.mapper"></property>
	<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>

<!-- 配置sqlSessionFactoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<!--配置数据源属性  -->
	<property name="dataSource" ref="dataSource"></property>
	<!-- 配置mybatis文件在控制台打印sql语句 -->
	<property name="configLocation" value="classpath:mybatis-config.xml"></property>
	<!-- 配置pageHelper -->
	<property name="plugins">
		<array>
			<bean class="com.github.pagehelper.PageInterceptor">
				<property name="properties">
					<value>param1=value1</value>
				</property>
			</bean>
		</array>
	</property>
</bean>

<!-- 管理注解信息 -->
<context:annotation-config/>

<!-- 扫描指定包下配置了注解的类，除了controller包 -->
<context:component-scan base-package="com.officn.*">
	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!-- 给业务层配置事务 -->
<tx:annotation-driven transaction-manager="txManager"/>

3、在springmvc-servlet.xml里面配置：

<?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:mvc="http://www.springframework.org/schema/mvc"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
				       http://www.springframework.org/schema/beans/spring-beans.xsd
				       http://www.springframework.org/schema/mvc 
					   http://www.springframework.org/schema/mvc/spring-mvc.xsd
				       http://www.springframework.org/schema/context
				       http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 配置静态资源访问 -->
<mvc:default-servlet-handler />

<!-- 自动注入组件 -->
<mvc:annotation-driven conversion-service="conversionService" >

</mvc:annotation-driven>

<!-- 配置controller扫描 -->
<context:component-scan
	base-package="com.offcn.house.controller" />

<!-- 配置视图解析器 -->
<bean
	class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/"></property>
	<property name="suffix" value=".jsp"></property>
</bean>

<!-- 日期转换器 -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
	<property name="converters">
		<list>
			<bean class="com.offcn.house.converter.DateConverter"></bean>
		</list>
	</property>
</bean>

4、在mybatis-config.xml里面：

<?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>
	<settings>
 	  	 <!-- 打印查询语句 -->
  	 	 <setting name="logImpl" value="STDOUT_LOGGING" />
	 </settings>
</configuration>

5、在pojo类里写：

private int tid;
private String tname;

public int getTid() {
	return tid;
}
public void setTid(int tid) {
	this.tid = tid;
}
public String getTname() {
	return tname;
}
public void setTname(String tname) {
	this.tname = tname;
}
@Override
public String toString() {
	return "Topic [tid=" + tid + ", tname=" + tname + "]";
}

6、在service接口里写：

List<Topic>  findAllTopic();

7、在mapper接口里写：

List<Topic>  findAllTopic();

8、在mapper.xml里面配置：

<mapper namespace="com.officn.mapper.TopicMapper">
	<select id="findAllTopic" resultType="com.officn.pojo.Topic">
		select * from topic 
	</select>
</mapper>

9、在serviceimpl类里写：

@Service("topicService")
public class TopicServiceImpl implements ITopicService {
	@Resource
	private TopicMapper topicMapper;	
	@Override
	public List<Topic> findAllTopic() {		
		return topicMapper.findAllTopic();
	}
}

10、在controller类里面写：

@Controller
public class TopicController {
	@Resource
	private ITopicService topicService;	
	@RequestMapping("/showTopic")
	public String showTopic(HttpSession session){
		List<Topic> list = topicService.findAllTopic();	
		session.setAttribute("list", list);
		return "redirect:/index.jsp";
	}
}

11、前端${list}接收，输入地址是http://localhost:8080/ssmenvironment/showTopic，数据出来了，成功。

12、需要资源的可以底下留言哈，以上配置可直接粘贴使用。。。
