二.Spring核心配置文件（applicationContext.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"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="

<!--配置数据源-->
<bean class="com.alibaba.druid.pool.DruidDataSource" name="dataSource">
<property name="driverClassName" value="${driverClassName}"/>
<property name="url" value="${url}"/>
<property name="username" value="${user}"/>
<property name="password" value="${password}"/>
<!-- 初始化连接大小 -->
<property name="initialSize" value="0" />
<!-- 连接池最大使用连接数量 -->
<property name="maxActive" value="30" />
<!-- 连接池最小空闲 -->
<property name="minIdle" value="0" />
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="60000" />
</bean>
<!--================== Spring和MyBatis的整合 =============== -->
<!--配置sqlSessionFactoryBean-->
<bean class="org.mybatis.spring.SqlSessionFactoryBean" name="sqlSessionFactory">
<!--数据库连接池-->
<property name="dataSource" ref="dataSource"/>
<!--加载mybatis的全局配置文件-->

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开-->
<property name="basePackage" value="com.java.dao"/>
</bean>
<!-- =============== 事务控制的配置 ================ -->
<!--spring的声明式事务管理XML方式，思想：AOP-->
<!--创建事务管理器对象-->
<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--使用注释事务 -->
<tx:annotation-driven transaction-manager="transactionManager" />
<!--配置事务增强对象, 事务通知-->
<tx:advice transaction-manager="transactionManager" id="txAdvice">
<tx:attributes>
<!--传播行为，其中*为通配符，即代表以sel为开头的所有方法，即表示符合此命名规则的方法作为一个事务-->
<tx:method name="*" rollback-for="java.lang.RuntimeException"/>
<tx:method name="find*" read-only="true"/>
<tx:method name="*" isolation="DEFAULT"/>

</tx:advice>
<!--配置AOP增强-->

<!--配置事物增强-->
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
</beans>
三.MyBatis核心配置文件（mybatis-config.xml）
<?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>
<!--全局配置-->
<settings>
<!--是否允许使用列别名-->
<setting name="useColumnLabel" value="false"/>
<!--是否允许获取自增值-->
<setting name="useGeneratedKeys" value="true"/>
<!--配置日志类-->
<setting name="logImpl" value="LOG4J"/>
<!--配置懒加载（）-->
<setting name="lazyLoadingEnabled" value="true"/>
<!--开启二级缓存-->
<setting name="cacheEnabled" value="true"/>
</settings>
<!--配置别名，为实体类起一个别名-->
<typeAliases>
<package name="com.java.entity"/>
</typeAliases>
<!--配置分页插件-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<!--mysql方言-->
<property name="helperDialect" value="mysql"/>
<!--合理化-->
<property name="reasonable" value="true"/>
</plugin>
</plugins>
</configuration>
mybatis配置懒加载时需要在所有相关的类前加上@JsonIgnoreProperties, 作用是json序列化时忽略bean中的一些属性序列化和反序列化时抛出的异常
@JsonIgnoreProperties(value = {"handler"})
四.SprigMVC核心配置文件（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: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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--引入spring配置-->
<import resource="classpath:applicationContext.xml"/>
<!--配置JSP（JSTL）视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--前缀-->
<property name="prefix" value="/WEB-INF/pages/"/>
<!--后缀-->
<property name="suffix" value=".jsp"/>
</bean>
<!--过滤静态资源-->
<mvc:resources mapping="/css/*" location="/css/"/>
<mvc:resources mapping="/images/*" location="/images/"/>
<mvc:resources mapping="/js/*" location="/js/"/>
<!--不拦截静态资源（html,css,js,jpg,png....）-->
<mvc:default-servlet-handler/>
<!--配置允许直接访问的jsp页面-->
<mvc:view-controller path="/index" view-name="index"/>
<!--对文件上传的解析-->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />
<!--配置spring mvc的注解驱动-->
<mvc:annotation-driven/>
<!-- 设置返回json的编码格式 -->
<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonConverter"/>
</list>
</property>
</bean>
</beans>
五.web.xml
<?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_4_0.xsd"
version="4.0">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!--配置SpringMVC-->
<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>
<!--配置SpringMVC什么时候启动，参数必须为整数,如果小于0，则在第一次请求进来的时候启动,如果为0或者大于0，则springMVC随着容器启动而启动-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!--所有的请求都进入springMVC-->
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置SpringMVC的字符集过滤器-->
<filter>
<filter-name>CharsetFilter</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>CharsetFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
六.database.properties配置文件
driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/demo?characterEncoding=utf8
user=root
password=123456
注意这里有个坑：
mysql 5.5 驱动是 com.mysql.jdbc.Driver
mysql 5.6 驱动是 com.mysql.cj.jdbc.Driver
七.log4j.properties配置文件
#debug->info->warn->error->fatal
#log4j.rootLogger=debug, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[%-5p]:(%t)%m %n
### 把日志信息输出到文件：log.html ###
log4j.appender.f1=org.apache.log4j.FileAppender
log4j.appender.f1.File=log.html
log4j.appender.f1.layout=org.apache.log4j.HTMLLayout
### 把日志信息输出到数据库 ###
log4j.appender.sql=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.sql.Driver=com.mysql.jdbc.Driver
log4j.appender.sql.URL=jdbc:mysql://127.0.0.1:3306/db9?useUnicode=true&characterEncoding=utf8
log4j.appender.sql.User=root
log4j.appender.sql.Password=123456
log4j.appender.sql.Sql=insert into `log4j`(`time`,`level`,`message`, `thread`) values(now(),'%p','%m','%t')
### 根记录器：设置优先级别、以及输出源 ###
log4j.rootLogger=debug,A1
八.JUnit4单元测试
package com.java.dao;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class CinemaDaoTest {
@Resource
private CinemaDao cinemaDao;
@Test
public void cinemaListAndHall() {
System.out.println(cinemaDao.cinemaListAndHall());
}
}
九.Mybatis映射文件头部约束（mapper）
<?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" >
<mapper>
</mapper>
十.Mybatis配置头部约束(config)
<?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>
十一.全局异常
package com.java.advice;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
@ControllerAdvice
@ResponseBody
public class MyExceptionHandler {
/**
* 原理AOP，捕获全局异常
*
* @param ex
* @return
*/
@ExceptionHandler(value = Exception.class)
private ModelAndView exHandler(Exception ex) {
ModelAndView mav = new ModelAndView("error");
mav.addObject("msg", ex.getMessage());
return mav;
}
}
