SpringMVC-Spring-MyBatis-Freemarker整合+源码下载

前言：之前看过很多大神写的SSM整合，但一直没亲自动手去这搞过，对于这三个框架的整合脑子中也是模模糊糊，今天决定去弄一下，加深一下自己对他们的印象，而且我也会把最常用的前端框架FreeMarker整合到一起，以及拦截器和过滤器的使用，小弟也是第一次整合这几个常用的框架，如有错误，敬请包涵和指出。

框架版本：Spring4.0, Mybatis3.2.0, Freemarker 2.3.16

数据库：Oracle11g

服务器：Tomcat7.0

开发工具：MyEclipse

第一步：创建名称为ssm的web项目,并导入所需jar,整个项目结构以及所需所有jar如下图所示：



WebRoot目录下：



第二部：建表(我这里使用PL/SQL操作)、创建序列、插入数据

create table USERINFO
(
id        VARCHAR2(50) not null primary key,
name      VARCHAR2(50),
age       VARCHAR2(50),
loginname VARCHAR2(50),
password  VARCHAR2(50)
)

create sequence SEQ_ID
minvalue 1
maxvalue 99999
start with 22
increment by 1
cache 20
order;

insert into userInfo(id,name,age,loginName,password) values(seq_id.nextval,'超级管理员'，'26','admin','123456')

第三步：创建实体，映射接口及实现，相当于以前的dao层接口和dao层实现

package com.xujd.model;

/**
* 用户实体
* @ClassName User
* @Description TODO
* @author XuJD
* @date 2017-6-6
*/
public class User{

private String id;
private String name;
private String age;
private String loginName;
private String password;

public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

package com.xujd.mapper;

import java.util.List;

import com.xujd.model.User;

public interface UserMapper {
void save(User op);
boolean update(User op);
boolean delete(int id);
User findById(int id);
List<User> findAll();
User login(User user);
}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--
namespace：必须与对应的UserMapper.java接口全类名一致
id:必须与对应接口的某个对应的方法名一致
-->
<mapper namespace="com.xujd.mapper.UserMapper" >
<sql id="UPDATE_USERINFO_ITEMS">
<trim prefix="set" suffixOverrides=",">
<if test="name!=null and name!=''">
name=#{name},
</if>
<if test="age!=null and age!=''">
age=#{age},
</if>
<if test="loginName!=null and loginName!=''">
loginName=#{loginName},
</if>
<if test="password!=null and password!=''">
password=#{password},
</if>
</trim>
</sql>
<insert id="save" parameterType="User" flushCache="true">
insert into userInfo(id,name,age,loginName,password)
values(seq_id.nextval,#{name},#{age},#{loginName},#{password})
</insert>
<update id="update" parameterType="User" flushCache="true">
update userInfo
<include refid="UPDATE_USERINFO_ITEMS"/>
where id=#{id}
</update>
<delete id="delete" parameterType="int" flushCache="true">
delete userInfo where id=#{id}
</delete>
<select id="findById" parameterType="int" resultType="User" useCache="true" >
select * from userInfo where id=#{id}
</select>
<select id="findAll" resultType="User" useCache="true">
select * from userInfo
</select>
<select id="login" resultType="User" parameterType="User" useCache="true">
select * from userInfo where loginName=#{loginName} and password=#{password}
</select>
</mapper>

第四步：Mybatis配置文件

<?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>

<!-- 实体类,简称 -设置别名 -->
<typeAliases>
<typeAlias alias="User" type="com.xujd.model.User" />
</typeAliases>
<!-- 实体接口映射资源 -->
<!--
说明：如果xxMapper.xml配置文件放在和xxMapper.java统一目录下，mappers也可以省略，
因为org.mybatis.spring.mapper.MapperFactoryBean默认会去查找与xxMapper.java相同目录和名称的xxMapper.xml
-->
<mappers>
<mapper resource="com/xujd/mapper/UserMapper.xml" />
</mappers>

</configuration>

第五步：SpringMVC配置文件

<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> 
<!-- 开启注解 -->
<mvc:annotation-driven />
<mvc:default-servlet-handler />
<!-- 注解扫描包 -->
<context:component-scan base-package="com.xujd" />

<!--
配置静态资源，直接映射到对应的文件夹，不被DispatcherServlet处理，3.04新增功能，需要重新设置spring-mvc-3.0.xsd
-->
<mvc:resources mapping="/img/**" location="/img/" />
<mvc:resources mapping="/js/**" location="/js/" />
<mvc:resources mapping="/css/**" location="/css/" />
<mvc:resources mapping="/html/**" location="/html/" />
//配置拦截器
<mvc:interceptors>
<mvc:interceptor>
<!-- 需拦截的请求 -->
<mvc:mapping path="/bg/user/*"/>
<bean class="com.xujd.interceptor.LoginInterceptor"/>
</mvc:interceptor>
</mvc:interceptors>

<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<!-- Jsp视图解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面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="/jsp/" />
<property name="suffix" value=".jsp" />
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="order" value="1" /><!--jsp设置为1，ftl设置为0，表示先找ftl,没有再找jsp -->
</bean>

<!-- FreeMarker视图解析器 -->
<bean id="viewResolverFtl" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="order" value="0" />
<property name="suffix" value=".ftl" />
<property name="contentType" value="text/html;charset=utf-8" />
<property name="viewClass">
<value>org.springframework.web.servlet.view.freemarker.FreeMarkerView</value>
</property>
</bean>

<!-- 配置freeMarker的模板路径 -->
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<!-- <property name="templateLoaderPaths" > ftl多路径配置
<list>
<value>/ftl/user/</value>
<value>/ftl/test/</value>
</list>
</property> -->
<property name="templateLoaderPath" value="/ftl/"/>
<property name="freemarkerVariables">
<map>
<entry key="xml_escape" value-ref="fmXmlEscape" />
</map>
</property>
<property name="defaultEncoding" value="utf-8" />
<property name="freemarkerSettings">  <!-- 设置FreeMarker环境属性 -->
<props>
<prop key="template_update_delay">0</prop><!--刷新模板的周期，单位为秒 -->
<prop key="default_encoding">UTF-8</prop>  <!--模板的编码格式 -->
<prop key="locale">UTF-8</prop><!-- 本地化设置 -->

<prop key="date_format">yyyy-MM-dd</prop>
<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
<prop key="classic_compatible">true</prop>
<prop key="template_exception_handler">ignore</prop>
</props>
</property>
</bean>
<bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/>
</beans>

第六步：Spring-Common配置文件（Spring、Mybatis整合）

<?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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

<!-- 注册jdbc属性文件(1) -->
<!-- <context:annotation-config/>
<context:property-placeholder location="classpath:db.properties"/>  -->

<!-- 1. 数据源 : DriverManagerDataSource -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@192.168.2.17:1521:yx" />
<property name="username" value="ts_yx" />
<property name="password" value="ts_yx" />
</bean>

<!--
2. mybatis的SqlSession的工厂: SqlSessionFactoryBean dataSource:引用数据源
MyBatis定义数据源,同意加载配置
-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:config/mybatis-config.xml" />
</bean>

<!--
3. mybatis自动扫描加载Sql映射文件/接口 : MapperScannerConfigurer sqlSessionFactory
basePackage:指定sql映射文件/接口所在的包（自动扫描）
-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.xujd.mapper"></property>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>

<!--
4. 事务管理 : DataSourceTransactionManager dataSource:引用上面定义的数据源
-->
<bean id="txManager"
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="txManager" />

</beans>

第七步：web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
<!-- 设置Spring容器加载所有的配置文件的路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring-*.xml</param-value>
</context-param>

<!-- 配置SpringMVC核心控制器 -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置初始配置化文件,前面contextConfigLocation看情况二选一 -->
<!-- init-param 节点必须在 load-on-startup 节点以上 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring-mvc.xml</param-value>
</init-param>
<!-- 启动加载一次 -->
<load-on-startup>1</load-on-startup>
</servlet>

<!--为DispatcherServlet建立映射 -->
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 加载Spring容器配置 -->
<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>

<!-- 解决工程编码过滤器 -->
<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>

<welcome-file-list>
<welcome-file>/index.ftl</welcome-file>
</welcome-file-list>

<!-- session有效时间，单位分钟 -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>

<!--    过滤器配置 -->
<filter>
<filter-name>backFilter</filter-name>
<filter-class>com.xujd.filter.BackFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>backFilter</filter-name>
<url-pattern>/bg/*</url-pattern>//需要过滤的请求
</filter-mapping>
</web-app>

第八步：过滤器和拦截器比较简单，在配置文件中有详细说明，下面看效果图吧，界面很low，可以忽视







在这里，拦截器和过滤器的作用是作为一个登入校验，没有登入的情况下访问系统会直接跳转到登入页面

总结：这几个框架整合还是相对简单的，虽然当中遇到一些问题，但是解决了，其他代码我就不一一贴出来了，我会把源码贴出来。
