这篇文章用来总结一下spring,springmvc,spring+mybatis,spring+hibernate的配置文件
要使用spring,必须在web.xml中定义分发器等信息,基本的配置信息如下:
<?xml version="1.0" encoding= "UTF-8"?>
<web-app version= "3.0" 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_3_0.xsd" >
<!-- 配置spring分发器,spring表示对应的 servlet【名可以改】配置文件为spring-servlet.xml -->
<servlet >
<servlet-name >spring </servlet-name >
<servlet-class >org.springframework.web.servlet.DispatcherServlet </servlet-class >
</servlet >
<servlet-mapping >
<!-- 会拦截.do请求-->
<servlet-name >spring </servlet-name >
<url-pattern >*.do </url-pattern >
</servlet-mapping >
< display-name></display-name >
< welcome-file-list>
<welcome-file >index.jsp </welcome-file >
</ welcome-file-list>
</web-app>
<!-- 该配置文件为spring的基本配置文件, springmvc,aop ,transaction等的配置均在此基础上进行 -->
<beans xmlns= "http://www.springframework.org/schema/beans" xmlns:context= "http://www.springframework.org/schema/context" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" 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 " >
<!-- 对com包下进行扫描,以完成对bean的创建和自动依赖注入 -->
<context:component-scan base-package ="com"/>
</beans>
<!-- 该配置文件为 springmvc的基本配置文件 -->
<!-- 相比较spring,增加了 mvc的命名空间与注解驱动 -->
<beans xmlns= "http://www.springframework.org/schema/beans" xmlns:context= "http://www.springframework.org/schema/context" xmlns:mvc= "http://www.springframework.org/schema/mvc" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" 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 " >
<!-- 对com包下进行扫描,以完成对bean的创建和自动依赖注入 -->
<context:component-scan base-package ="com"/>
<!-- mvc层提供的注解驱动[注册用于解析@ResponseBody注解的类] 当controller中的方法需要返回 json数据时,需要用到@ResponseBody注解,此时需呀添加此驱动 -->
<mvc:annotation-driven />
</beans>
以下为springmvc+hibernate的配置文件,去掉mvc命名空间等配置即为spring+hibernate的配置文件
<!-- 该配置文件为 springmvc+hibernate 的基本配置文件 -->
<!-- 相比较springmvc,增加了hibernate 的配置 -->
<beans xmlns= "http://www.springframework.org/schema/beans" xmlns:context= "http://www.springframework.org/schema/context" xmlns:mvc= "http://www.springframework.org/schema/mvc" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" 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 " >
<!-- 对com包下进行扫描,以完成对bean的创建和自动依赖注入 -->
<context:component-scan base-package ="com"/>
<!-- mvc层提供的注解驱动[注册用于解析@ResponseBody注解的类] 当controller中的方法需要返回 json数据时,需要用到@ResponseBody注解,此时需呀添加此驱动 -->
<mvc:annotation-driven />
<!-- 配置hibernate 开始 -->
<bean id ="ht" class= "org.springframework.orm.hibernate3.HibernateTemplate" >
<!-- 指向session工厂 -->
<property name ="SessionFactory" ref= "sf"></property >
</bean >
<!-- 配置session工厂 a setAnnotatedClasses(Class[] claes) 指向映射实体bean列表 每在工程中添加一个映射实体bean,就需要在list元素下添加一个value子元素指向该实体bean b setPackagesToScan(String package) 扫描实体bean所在的包结构,在包下查找所有的映射实体 -->
<bean name ="sf" class= "org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" >
<property name ="dataSource" ref="ds"></ property>
<!-- 映射实体bean 配置bean所在的包-->
<property name ="packagesToScan" value= "com.po,com.ngsh.bean"></property ><!-- 如果有多个包有映射实体,都在value中写,用逗号隔开 -->
<property name ="hibernateProperties">
<props >
<prop key= "hibernate.show_sql">true</prop >
</props >
</property >
</bean >
<!-- hibernate的数据源 -->
<bean id ="ds" class= "org.springframework.jdbc.datasource.DriverManagerDataSource" >
<property name ="driverClassName" value= "com.mysql.jdbc.Driver"></property >
<property name ="url" value= "jdbc:mysql://localhost:3306/demo?characterEncoding=utf-8" ></property >
<property name ="username" value="root"></ property>
<property name ="password" value="root"></ property>
</bean >
</beans>
去掉mvc的相关配置即为spring+mybatis的配置文件
<!-- 该配置文件为 springmvc+mybatis 的基本配置文件 -->
<!-- 相比较springmvc,增加了mybatis 的配置 -->
<beans xmlns= "http://www.springframework.org/schema/beans" xmlns:context= "http://www.springframework.org/schema/context" xmlns:mvc= "http://www.springframework.org/schema/mvc" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" 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 " >
<!-- 对com包下进行扫描,以完成对bean的创建和自动依赖注入 -->
<context:component-scan base-package ="com"/>
<!-- mvc层提供的注解驱动[注册用于解析@ResponseBody注解的类] 当controller中的方法需要返回 json数据时,需要用到@ResponseBody注解,此时需呀添加此驱动 -->
<mvc:annotation-driven />
<!-- 配置mybatis 开始 -->
<!-- 在ioc容器中配置sqlSessionFactory -->
<bean id ="ssf" class= "org.mybatis.spring.SqlSessionFactoryBean" >
<!-- 配置数据源 指向 ds -->
<property name ="dataSource" ref="ds"></property>
<!-- 配置映射文件 当有多个时 在list中添加-->
<property name ="mapperLocations">
<list >
<!-- classpath +映射文件的路径 -->
<value> classpath:com.dao.UserDao-mapper.xml</value >
</list >
</property >
</bean >
<!-- mybatis的数据源 -->
<bean id ="ds" class= "org.springframework.jdbc.datasource.DriverManagerDataSource" >
<property name ="driverClassName" value= "com.mysql.jdbc.Driver"></property >
<property name ="url" value= "jdbc:mysql://localhost:3306/demo" ></property >
<property name ="username" value="root"></property>
<property name ="password" value="root"></property>
</bean >
<!-- 配置mapper.xml所映射的接口,-->
<!-- 方法一 每增加一个接口类就得新增一个对应的bean进行注册 -->
<!-- <bean id ="userDao" class= "org.mybatis.spring.mapper.MapperFactoryBean" > 指向sessionFactory <property name ="sqlSessionFactory" ref= "ssf"></property > <property name ="mapperInterface" value= "com.dao.UserDaoIf"></property > </bean > -->
<!-- 方法二 直接扫描dao包 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.dao" />
<property name="sqlSessionFactoryBeanName" value="ssf"></property>
</bean>
</beans>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 声明命名空间即其所映射的接口 -->
<mapper namespace= "com.dao.UserDaoIf">
<!-- parameterType指定参数类型,多个参数使用map resultMap指定结果集 -->
<select id ="selectById" parameterType="java.util.map" resultMap= "user">
select * from user where name=#{name} and pw=#{pw };
</select >
<!-- resultType表示返回int 型 -->
<select id ="selectUserCount" resultType= "java.lang.Integer">
select count(*) from user;
</select >
<!-- 修改 -->
<update id ="uppw" parameterType="java.util.Map" >
update user set pw=#{pw} where id=#{id};
</update >
<delete id ="removeById" parameterType="java.lang.Integer">
delete from user where id=#{id};
</delete >
<!-- 定义返回的结果集 使用select查询时可以使用resultType[返回类型如java.lang.String],也可以使用resultMap, 但两者不可以同时使用,可定义多个,通过id区分 -->
<resultMap type ="com.bean.User" id="user">
<result property ="id" column="id"/>
<result property ="name" column="name"/>
<result property ="pw" column="pw"/>
</resultMap >
</mapper>
