Maven Web项目配置Mybatis

时间：2022-04-06 05:13:33

一、添加Mybatis和数据库相关的包

1 pom.xml中添加的包有spring-jdbc,mybatis，mybatis-spring，druid，mysql-connector-java，commons-io，reflectasm

完整的pom.xml内容为

<project xmlns="http://maven.apache.org/POM/4.0.0"

2 /src/main/webapp/WEB-INF/lib/中添加cglib-3.1.jar

Maven Web项目配置Mybatis

二、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>jade_admin</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/config/spring/applicationContext-config.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>

<!-- 添加Spring-Security过滤器 -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/service/*</url-pattern>
</filter-mapping>

    <servlet>  
        <servlet-name>dispatcher</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>/WEB-INF/classes/config/spring/applicationContext-mvc.xml</param-value>  
        </init-param>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>dispatcher</servlet-name>  
        <url-pattern>/service/*</url-pattern>  
    </servlet-mapping>

</web-app>

三、配置applicationContext-config.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:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

<import resource="classpath*:config/spring/applicationContext-security.xml" />
<import resource="classpath*:config/spring/applicationContext-resources.xml" />

</beans>

四、配置applicationContext-resource.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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-3.2.xsd  
http://www.springframework.org/schema/tx  
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">


    <!-- 阿里 druid数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">  
         <!-- 数据库基本信息配置 -->
         <property name="url" value="jdbc:mysql://127.0.0.1:3306/jade?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&zeroDateTimeBehavior=convertToNull" />  
         <property name="username" value="root" />  
         <property name="password" value="123456" />  
         <property name="driverClassName" value="com.mysql.jdbc.Driver" />  
         <property name="filters" value="stat" />  
    <!-- 最大并发连接数 -->
         <property name="maxActive" value="20" />
         <!-- 初始化连接数量 -->
         <property name="initialSize" value="1" />
         <!-- 配置获取连接等待超时的时间 -->
         <property name="maxWait" value="60000" />
         <!-- 最小空闲连接数 -->
         <property name="minIdle" value="10" />  
    <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
         <property name="timeBetweenEvictionRunsMillis" value="60000" />
         <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
         <property name="minEvictableIdleTimeMillis" value="300000" />  
         <property name="validationQuery" value="SELECT 'x'" />  
         <property name="testWhileIdle" value="true" />  
         <property name="testOnBorrow" value="false" />  
         <property name="testOnReturn" value="false" />  
         <property name="maxOpenPreparedStatements" value="20" />
         <!-- 打开removeAbandoned功能 -->
         <property name="removeAbandoned" value="true" />
         <!-- 1800秒，也就是30分钟 -->
         <property name="removeAbandonedTimeout" value="1800" />
         <!-- 关闭abanded连接时输出错误日志 -->   
         <property name="logAbandoned" value="true" />
</bean> 

<bean id="txManager"  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="txTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref="txManager" />
</bean>
<bean id="SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:config/mybatis/configuration.xml"/>
        <property name="mapperLocations" value="classpath*:config/mybatis/mapper/*Mapper.xml" />
        <property name="typeAliasesPackage" value="com.zheng.bean" />  
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.zheng.dao"/>
    <property name="sqlSessionFactory" ref="SqlSessionFactory" />
    </bean>

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

</beans>

五、配置configuration.xml

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE configuration   PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"   "http://ibatis.apache.org/dtd/ibatis-3-config.dtd">

<!-- "http://ibatis.apache.org/dtd/ibatis-3-config.dtd" -->
<!-- 
    plugins在配置文件中的位置必须符合要求，否则会报错，顺序如下:
    properties?, settings?, 
    typeAliases?, typeHandlers?, 
    objectFactory?,objectWrapperFactory?, 
    plugins?, 
    environments?, databaseIdProvider?, mappers?
-->
<configuration>
<properties>
</properties>
<!-- mybatis的内部配置 -->
<settings>
<!--使全局的映射器启用缓存  -->
<setting name="cacheEnabled" value="true" />
<!--启用延迟加载 ,当禁用时，所有关联对象都会即时加载 -->
<setting name="lazyLoadingEnabled" value="false" />
<!-- 当启用时，有延迟加载属性的对象在被调用时将会完全加载任意属性。否则，每种属性将会按需要加载  -->
<setting name="aggressiveLazyLoading" value="true" />
<!--允许多结果集返回, 允许或不允许多种结果集从一个单独的语句中返回（需要适合的驱动）-->
<setting name="multipleResultSetsEnabled" value="true" />
<!--使用列标签代替列名,不同的驱动在这方便表现不同。参考驱动文档或充分测试两种方法来决定所使用的驱动  -->
<setting name="useColumnLabel" value="true" />
<!--不能用生成键  -->
<setting name="useGeneratedKeys" value="false" />
<!-- 指定MyBatis如何自动映射列到字段/属性。PARTIAL只会自动映射简单，没有嵌套的结果。FULL会自动映射任意复杂的结果（嵌套的或其他情况）  -->
<setting name="autoMappingBehavior" value="PARTIAL" />
<!--默认执行器为SIMPLE,SIMPLE执行器没有什么特别之处。REUSE执行器重用预处理语句。BATCH执行器重用语句和批量更新   -->
<setting name="defaultExecutorType" value="SIMPLE" />
<!--超时时间2500毫妙,它决定驱动等待一个数据库响应的时间  -->
<setting name="defaultStatementTimeout" value="25000" />

<setting name="proxyFactory" value="CGLIB"/>
</settings>

</configuration>
