关于SSM框架搭建以及简单的增删改查

第一步.Maven框架的搭建

第二步.搭建完Maven后，我们来进行ssm框架的xml文件配置

<?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: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.xsd"> <!--启用spring的一些annotation --><context:annotation-config/><!-- 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.frank.controller"><!-- 扫描符合@Service @Repository的类 --><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!--HandlerMapping 无需配置，springmvc可以默认启动--><!--但是项目部署到linux下发现WEB-INF的静态资源会出现无法解析的情况，但是本地tomcat访问正常，因此建议还是直接把静态资源放在webapp的statics下，映射配置如下--><!--<mvc:resources mapping="/css/**" location="/statics/css/"/>--><!--<mvc:resources mapping="/js/**" location="/statics/js/"/>--><!--<mvc:resources mapping="/image/**" location="/statics/images/"/>--><!-- 配置注解驱动 可以将request参数与绑定到controller参数上 --><mvc:annotation-driven/><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀(如果最后一个还是表示文件夹,则最后的斜杠不要漏了) 使用JSP--><!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- --><bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="viewClass"4000value="org.springframework.web.servlet.view.JstlView"/><property name="prefix" value="/WEB-INF/views/"/><!--设置JSP文件的目录位置--><property name="suffix" value=".jsp"/></bean><!--springmvc文件上传需要配置的节点--><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="maxUploadSize" value="20971500"/><property name="defaultEncoding" value="UTF-8"/><property name="resolveLazily" value="true"/><!-- 是否使用延迟加载--></bean></beans>

<!--配置springmvc DispatcherServlet-->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!--Sources标注的文件夹下需要新建一个spring文件夹-->
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/configs/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=你的密码

#配置根Logger 后面是若干个Appender
log4j.rootLogger=DEBUG,A1,R
#log4j.rootLogger=INFO,A1,R

# ConsoleAppender 输出
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%c]-[%p] %m%n

# File 输出 一天一个文件,输出路径可以定制,一般在根路径下
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=logs/log.txt//log日志文件存储位置
log4j.appender.R.MaxFileSize=500KB
log4j.appender.R.MaxBackupIndex=10
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c] [%p] - %m%n

<?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:aop="http://www.springframework.org/schema/aop"

<!--1.1 引用注解-->
<context:component-scan base-package="com.frank"/>

<!--1.1 关联jdbc.properties-->
<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 01.配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>

<!-- mybatis和spring完美整合，不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:mapping/*.xml"></property>
</bean>

<!-- 03.生成dao代理對象-->//这里没有配置好的话注解找不到对象
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
<property name="basePackage" value="com.frank.dao"></property>
</bean>

</beans>

xml配置完成后 在web.xml 进行相同的文件声明

<!--配置Spring--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param>

<!-- 注册ServletContext监听器，创建容器对象，并且将ApplicationContext对象放到Application域中 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 防止spring内存溢出监听器，比如quartz --><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener>

配置完成后 ，我们的ssm框架算是已经稍微成型了

第三步  搭建mapper 映射首先创建实体类 User

public class User {private  int userID;private String userName;private String password;public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public int getUserID() {return userID;}public void setUserID(int userID) {this.userID = userID;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}}

package com.frank.dao;import com.frank.bean.User;import org.mybatis.spring.annotation.MapperScan;import org.springframework.stereotype.Component;import org.springframework.stereotype.Repository;import java.util.List;@Repository<!--这里使用注解-->public interface UserMapper {public void save(User user);public void update(User user);public User findById(int id);public List<User> findAll();public void deleteById(int id);}

<?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：必须与对应的接口全类名一致  UserMapper.javaid ：必须与对应接口的某个对应的方法名一致即必须要和UserMapper.java接口中的方法同名。--><mapper namespace="com.frank.dao.UserMapper"><resultMap id="StudentList" type="com.frank.bean.User"><id property="userID" column="userID"/><result property="userName" column="userName"/><result property="password" column="password"/></resultMap><insert id="save" parameterType="com.frank.bean.User">INSERT  into user(userName,passWord)  VALUES (#{userName},#{password})</insert><update id="update" parameterType="com.frank.bean.User">UPDATE  user SET userName=#{userName},passWord=#{password} where userID=#{userID}</update><select id="findByID" parameterType="int" resultType="com.frank.bean.User">SELECT * FROM  user WHERE userID=#{id}</select><select id="findAll" resultMap="StudentList">SELECT  * from user</select><delete id="deleteById" parameterType="int">DELETE  FROM USER  WHERE userID=#{id}</delete></mapper>

package com.frank.service;import com.frank.bean.User;import com.frank.dao.UserMapper;import org.springframework.beans.factory.annotation.Autowired;import java.util.List;public interface UserService {public void save(User user);public void update(User user);public User findById(int id);public List<User> findAll();public void deleteById(int id);}

package com.frank.servicelmpl;import com.frank.bean.User;import com.frank.dao.UserMapper;import com.frank.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import java.util.List;@Servicepublic class UserServicelmpl implements UserService {@Autowired()private UserMapper userMapper;public void save(User user) {userMapper.save(user);}public void update(User user) {userMapper.update(user);}public User findById(int id) {return userMapper.findById(id);}public List<User> findAll() {return userMapper.findAll();}public void deleteById(int id) {userMapper.deleteById(id);}}
