篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了总结文件配置相关的知识,希望对你有一定的参考价值。
总体大概目录
主要 配置:pom.xml 配置、web.xml配置、applicationContext.xml配置、springmvc.xml配置
日志log4j2.xml、xxMapper.xml配置;
对三层的MVC搭建:entity层、service层、controller层;
对象和SQL映射mapper层;
第一部分:文件初始化,文件配置
1 对pom.xml依赖下载

3、对web.xml进行配置
<?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">
<!-- 将前端配置文件注入 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:META-INF/applicationContext.xml</param-value>
</context-param>
<!-- 配置核心组件:前端控制器-->
<servlet>
<servlet-name>mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 初始化参数 servlet的声明周期 -->
<init-param>
<!-- 配置springmvc的核心配置文件-->
<param-name>contextConfigLocation</param-name>
<param-value>classpath:META-INF/springmvc.xml</param-value>
</init-param>
<!-- 配置服务器在启动的时候加载 <servlet> -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc</servlet-name>
<!-- 所有的servlet都生效-->
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 过滤器配置-->
<filter>
<filter-name>encoding</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>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 监听器配置 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<listener>
<listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
</listener>
<!-- 将log4j2.xml导入 -->
<context-param>
<param-name>log4jConfiguration</param-name>
<!--默认是classpath下的log4j2.xml-->
<param-value>classpath:log4j2.xml</param-value>
</context-param>
</web-app>
4、对applicationContext.xml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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
<!-- 1、 开启包扫描 主要是扫描mapper service 可以配置将controller排除掉-->
<context:component-scan base-package="org.lsj">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.RestController"/>
</context:component-scan>
<!--2、写数据源配置-->
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource">
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/patient?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8"></property>
<property name="username" value="root"></property>
<property name="password" value="123456"></property>
<!-- 数据库连接池中最大连接数量-->
<property name="maximumPoolSize" value="20"></property>
<!-- 配置测试连接是否可用的查询语句-->
<property name="connectionTestQuery" value="select 1"></property>
</bean>
<!-- 3、配置 SqlSessionFactory mybatis-spring-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- (1)、提供数据源-->
<property name="dataSource" ref="dataSource"></property>
<!-- (2)、mapper 的位置 相当于mybatis框架的mapper注册-->
<property name="mapperLocations" value="classpath:org/lsj/**/*.xml"></property>
</bean>
<!-- 4、mapper接口的扫描器,目的是将mybatis接口的实现类纳入spring容器-->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
<!-- (2)、要扫描的基础包:在基础包下进行递归扫描,找接口[会把service接口一并扫描]-->
<property name="basePackage" value="org.lsj"></property>
<!-- (3)、只扫描带有@mapper 的接口,过滤掉service接口-->
<property name="annotationClass" value="org.apache.ibatis.an以上是关于总结文件配置的主要内容,如果未能解决你的问题,请参考以下文章
