关于spring+springMVC+myBatis的一些基础配置以及整合

一、WEB.XML文件主要配置

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">  <welcome-file-list>      <welcome-file>index.jsp</welcome-file>  </welcome-file-list>    <!--设置session过期的时间-->  <session-config>      <session-timeout>20</session-timeout>  </session-config>    <!--读取spring的配置文件-->  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:config/spring.xml;classpath:config/spring-myBatis.xml</param-value>  </context-param>    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <listener>      <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  </listener>    <!--设置字符编码，将所有的字符编码同意设置为utf-8-->  <filter>      <filter-name>filterEncoding</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>filterEncoding</filter-name>      <url-pattern>/</url-pattern>  </filter-mapping>    <!--生成一次性验证码的servlet-->  <servlet>      <servlet-name>verifyCode</servlet-name>      <servlet-class>com.longhang.tool.verifyCode.VerifyCodeServlet</servlet-class>  </servlet>    <!--将所有*.do的请求交给springMVC的DispatcherServlet来处理-->  <servlet>      <servlet-name>DispatcherServlet</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:config/springMVC-config.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>  </servlet>    <servlet-mapping>      <servlet-name>verifyCode</servlet-name>      <url-pattern>/verifyCode</url-pattern>  </servlet-mapping>    <servlet-mapping>      <servlet-name>DispatcherServlet</servlet-name>      <url-pattern>*.do</url-pattern>  </servlet-mapping></web-app>

二、SPRINGMVC的配置文件

<?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:p="http://www.springframework.org/schema/p"            xmlns:context="http://www.springframework.org/schema/context"  xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd          http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd          http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <!--配置自动扫描的包，让其扫描com.longhang,controller下面的所有包-->  <context:component-scan base-package = "com.longhang.controller"></context:component-scan> <!--配置视图解析器将视图逻辑名解析为/*.jsp-->  <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">     <property name = "prefix" value = "/"></property>     <property name = "suffix" value = ".jsp"></property>  </bean></beans>

三、spring.xml的配置

<?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" xsi:schemaLocation="       http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd       http://www.springframework.org/schema/context       http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <context:property-placeholder location="classpath:config/druid.properties" />    <!-- 自动扫描(自动注入) -->    <context:component-scan base-package = "com.longhang.service"></context:component-scan></beans>

四、spring-myBatis.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: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-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">    <!-- 配置数据源 --><!--    <bean name = "datasource" class = "com.alibaba.druid.pool.DruidDataSource" init-method = "init" destroy-method = "close">        <property name ="url" value = "${jdbc_url}"></property>        <property name="username" value="${jdbc_userName}" />        <property name="password" value="${jdbc_password}" />    </bean>-->    <bean name = "datasource" class = "com.alibaba.druid.pool.DruidDataSource" init-method = "init" destroy-method = "close">        <property name ="url" value = "jdbc:mysql://localhost:8000/bookShopping"></property>        <property name="username" value="root" />        <property name="password" value="13072399672" />    </bean>        <!--配置sqlSessionFactory 并读取mybatis的一些配置-->    <bean name = "sqlSessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean">        <property name = "dataSource" ref = "datasource"></property>        <property name="mapperLocations" value="classpath:mapper/*.xml"/>    </bean>        <!--自动扫描 将Mapper接口生成代理注入到Spring-->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.longhang.dao" />        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />    </bean>        <!--配置事物-->    <bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name = "dataSource" ref = "datasource"></property>    </bean>        <!--<tx:annotation-driven transaction-manager = "transactionManager"/>-->      <!--事物的具体内容-->    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">        <tx:attributes>            <tx:method name="add*" propagation="REQUIRED" />            <tx:method name="append*" propagation="REQUIRED" />            <tx:method name="insert*" propagation="REQUIRED" />            <tx:method name="save*" propagation="REQUIRED" />            <tx:method name="update*" propagation="REQUIRED" />            <tx:method name="modify*" propagation="REQUIRED" />            <tx:method name="edit*" propagation="REQUIRED" />            <tx:method name="delete*" propagation="REQUIRED" />            <tx:method name="remove*" propagation="REQUIRED" />            <tx:method name="repair" propagation="REQUIRED" />            <tx:method name="delAndRepair" propagation="REQUIRED" />            <tx:method name="get*" propagation="SUPPORTS" />            <tx:method name="find*" propagation="SUPPORTS" />            <tx:method name="load*" propagation="SUPPORTS" />            <tx:method name="search*" propagation="SUPPORTS" />            <tx:method name="datagrid*" propagation="SUPPORTS" />            <tx:method name="*" propagation="SUPPORTS" />        </tx:attributes>    </tx:advice>    <!--定义一个切面,在定义的切面上加入事物-->    <aop:config>        <aop:pointcut id="transactionPointcut" expression="execution(* com.longhang.service..*Impl.*(..))" />        <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />    </aop:config></beans>

五、关于mybatis的映射文件

<?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 namespace="com.longhang.dao.userDao.UserDao" >  <resultMap id = "baseResultMap" type = "com.longhang.entity.user.User">      <id column = "uid" property = "uid" jdbcType = "CHAR"/>      <result column = "loginname" property = "loginname" jdbcType = "VARCHAR"/>      <result column = "loginpass" property = "loginpass" jdbcType = "VARCHAR"/>      <result column = "email" property = "email" jdbcType = "VARCHAR"/>      <result column = "status" property = "status" jdbcType = "VARCHAR"/>      <result column = "activationCode" property = "activationCode" jdbcType = "CHAR"/>  </resultMap>    <sql id = "base_column_list">      uid,loginname,loginpass,email,status,activationCode  </sql>   <!--根据id查询返回的类型为User-->  <select id="findById" resultMap="baseResultMap" parameterType="java.lang.String" >    select     <include refid="base_column_list" />    from l_user    where uid = #{uid,jdbcType=CHAR}  </select>    <!--根据activationCode查询返回值是User-->  <select id = "findByActivationCode" resultMap = "baseResultMap" parameterType = "java.lang.String">    select <include refid = "base_column_list"/>    from l_user    where activationCode = #{activationCode}  </select>    <!--根据loginname查看总条数-->  <select id = "countNumberByLoginName" resultType = "int" parameterType="java.lang.String">    select count(*) from l_user where loginname = #{loginname}  </select>    <!--根据email查看总条数-->  <select id = "countNumberByEmail" resultType = "int" parameterType = "java.lang.String">    select count(*) from l_user where email = #{email}  </select>     <select id = "isActivation" resultType = "int" parameterType = "java.lang.String">    select count(*) from l_user where activationCode = #{activationCode}  </select>  <delete id = "deleteById" parameterType = "java.lang.String">    delete from l_user where uid = #{uid,jdbcType=CHAR}  </delete>     <insert id = "addUser" parameterType = "com.longhang.entity.user.User">    insert into l_user(uid,loginname,loginpass,email,status,activationCode)    values(#{uid},#{loginname},#{loginpass},#{email},#{status},#{activationCode})  </insert> <!--  <insert id="insertSelective" parameterType="com.bky.model.Add" >    insert into tadd    <trim prefix="(" suffix=")" suffixOverrides="," >      <if test="id != null" >        id,      </if>      <if test="tname != null" >        tname,      </if>      <if test="tpwd != null" >        tpwd,      </if>    </trim>    <trim prefix="values (" suffix=")" suffixOverrides="," >      <if test="id != null" >        #{id,jdbcType=VARCHAR},      </if>      <if test="tname != null" >        #{tname,jdbcType=VARCHAR},      </if>      <if test="tpwd != null" >        #{tpwd,jdbcType=VARCHAR},      </if>    </trim>  </insert>-->  <!--  <update id="updateByPrimaryKeySelective" parameterType="com.bky.model.Add" >    update tadd    <set >      <if test="tname != null" >        tname = #{tname,jdbcType=VARCHAR},      </if>      <if test="tpwd != null" >        tpwd = #{tpwd,jdbcType=VARCHAR},      </if>    </set>    where id = #{id,jdbcType=VARCHAR}  </update>-->  <update id = "updateById" parameterType="com.longhang.entity.user.User">   update l_user   set uid = #{uid},     loginname = #{loginname},     loginpass = #{loginpass},     email = #{email},     status = #{status},     activationCode = #{activationCode}     where uid = #{uid}  </update>    <update id="updatePropByID">    update  l_user set  <foreach collection="prop" item="item" index="index" separator=",">     ${item.key} = #{item.value}  </foreach>  <where>     uid = #{uid}  </where>  </update>  <update id="updatePropByCondition">  <![CDATA[  update  l_user set]]>  <foreach collection="prop" item="item" index="index" separator=",">     ${item.key} = #{item.value}  </foreach>  <where>  <if test="condition != null">     ${condition}  </if>  </where>  </update>    <select id="getAll" resultMap="baseResultMap">    SELECT * FROM uid  </select></mapper>

六、接口

package com.longhang.dao.userDao;import java.util.List;import java.util.Map;import java.util.Set;import java.util.Map.Entry;import org.apache.ibatis.annotations.Param;import com.longhang.entity.user.User;public interface UserDao {    public User findById(String uid);    public int deleteById(String uid);    public int addUser(User user);    public int updateById(String uid);    public List<User> getAll();    public int countNumberByLoginName(String loginname);    public int countNumberByEmail(String email);    public int isActivation(String activationCode);    public User findByActivationCode(String activationCode);    public int updatePropByID(@Param("prop")Set<Entry<String, Object>> prop,@Param("uid")String id);    public int updatePropByCondition(@Param("prop")Set<Entry<String,Object>> prop,@Param("condition")String condition);}
