2.整合mvc
2.1配置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:p="http://www.springframework.org/schema/p" 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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.javen.controller" /> <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 --> <mvc:annotation-driven/> <!-- 静态资源处理 css js imgs --> <mvc:resources location="/resources/**" mapping="/resources"/> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --> </list> </property> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> <!-- 启用是为了推迟文件解析，以便捕获文件大小异常 --> <property name="resolveLazily" value="true"/> </bean> <!-- 配置ViewResolver 。可用多个ViewResolver 。使用order属性排序。 InternalResourceViewResolver 放在最后--> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="1"></property> <property name="mediaTypes"> <map> <!-- 告诉视图解析器，返回的类型为json格式 --> <entry key="json" value="application/json" /> <entry key="xml" value="application/xml" /> <entry key="htm" value="text/htm" /> </map> </property> <property name="defaultViews"> <list> <!-- ModelAndView里的数据变成JSON --> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" /> </list> </property> <property name="ignoreAcceptHeader" value="true"></property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
2.2配置web.xml文件
配置的spring-mvc的Servlet就是为了完成SpringMVC+MAVEN的整合。
web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <!-- <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> --> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring监听器 --> <!-- <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> --> <!-- 防止Spring内存溢出监听器 --> <!-- <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> --> <!-- Spring MVC servlet --> <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> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
3.Spring与MyBatis的整合
3.1建立JDBC属性文件
jdbc.pro
driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///invoicingsystem
user=root
password=123
3.2建立application-mybatis.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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--加載屬性文件--> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <array> <value>classpath*:*.properties</value> </array> </property> </bean> <!--配置数据源--> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="url" value="${url}"></property> <property name="driverClassName" value="${driver}"></property> <property name="username" value="${user}"></property> <property name="password" value="${password}"></property> </bean> <!--配置SqlSessionFactoryBean--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="mapperLocations" value="classpath*:mapper/*.xml"></property> <property name="typeAliasesPackage" value="cn.Project.entity"></property> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageHelper"> <property name="properties"> <value> <!-- 数据库方言 --> dialect=mysql </value> </property> </bean> </array> </property> </bean> <!--包扫描--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.Project"></property> </bean> <!--事务管理器--> <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!--开启各种注解配置--> <tx:annotation-driven/> <context:annotation-config/> <context:component-scan base-package="cn.Project"></context:component-scan> </beans>
4.创建Usersentity实现类
private int uid; private String userName; private String password; private String realName;
5.创建Dao层接口
@Repository("iUsersDao")
public interface IUsersDao {
//登录
Users getlogin(@Param("userName") String userName,@Param("password") String password);
}
6.编写UersDao.xml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"> <!--namespace需要指向接口全路径--> <mapper namespace="cn.Project.dao.IUsersDao"> <!--登录--> <select id="getlogin" resultType="cn.Project.entity.Users"> SELECT * FROM users WHERE userName=#{userName} AND PASSWORD=#{password} </select> </mapper>
7.创建Service接口
public interface IUsersService { //登录 Users getlogin(String userName, String password); }
8.创建ServiceImpl实体类
@Service("iUsersService")
public class IUsersServiceImpl implements IUsersService {
@Resource(name = "iUsersDao")
private IUsersDao iUsersDao;
@Override
public Users getlogin(String userName, String password) {
return iUsersDao.getlogin(userName,password);
}
}
9.进行测试
