SSM框架整合---實(shí)現(xiàn)簡(jiǎn)單登錄注冊(cè)功能 2017年06月25日 18:13:02 閱讀數(shù)：58920 1、新建工程，整合jar包 2、數(shù)據(jù)庫（oracle）鍵表，包含id，name，password三個(gè)字段 3、配置db.propertise文件，用于配置數(shù)據(jù)源 [plain] view plain copy url=jdbc:oracle:thin:@localhost:1521:XE user=oracle passwd=123 driver=oracle.jdbc.OracleDriver
3、配置spring相關(guān)文件，取名為spring.xml，放在src目錄下，詳見配置文件 [html] view plain copy <?xml version='1.0' encoding='UTF-8'?> <beans xmlns='http://www./schema/beans' xmlns:xsi='http://www./2001/XMLSchema-instance' xmlns:context='http://www./schema/context' xmlns:aop='http://www./schema/aop' xmlns:tx='http://www./schema/tx' xsi:schemaLocation='http://www./schema/beans http://www./schema/beans/spring-beans.xsd http://www./schema/context http://www./schema/context/spring-context.xsd http://www./schema/aop http://www./schema/aop/spring-aop.xsd http://www./schema/tx http://www./schema/tx/spring-tx.xsd'> <!--引入propertise文件 --> <!--傳統(tǒng)方式引入 --> <!-- <bean class='org.springframework.beans.factory.config.PropertyPlaceholderConfigurer'> --> <!-- <property name='locations' value='classpath:db.properties'></property> --> <!-- </bean> --> <!--簡(jiǎn)化方式 --> <context:property-placeholder location='classpath:db.properties'/> <!--1.配置數(shù)據(jù)源:c3p0 --> <bean id='dataSource' class='com.mchange.v2.c3p0.ComboPooledDataSource'> <property name='driverClass' value='${driver}' /> <property name='jdbcUrl' value='${url}' /> <property name='user' value='${user}' /> <property name='password' value='${passwd}' /> </bean> <!--2.配置mybatis的SqlSession的工廠: SqlSessionFactoryBean dataSource:引用數(shù)據(jù)源 --> <bean id='sqlSessionFactory' class='org.mybatis.spring.SqlSessionFactoryBean'> <property name='dataSource' ref='dataSource'></property> <property name='typeAliasesPackage' value='com.ssm.bean' /> </bean> <!-- 3. 自動(dòng)掃描mybatis映射文件和接口的包 --> <bean class='org.mybatis.spring.mapper.MapperScannerConfigurer'> <property name='basePackage' value='com.ssm.dao'></property> </bean> <!--4.配置事務(wù)管理器 --> <bean id='transactionManager' class='org.springframework.jdbc.datasource.DataSourceTransactionManager'> <property name='dataSource' ref='dataSource'></property> </bean> <!--5.開啟注解進(jìn)行事務(wù)管理 transaction-manager：引用上面定義的事務(wù)管理器--> <tx:annotation-driven transaction-manager='transactionManager'/> </beans>
4、配置springmvc相關(guān)文件，取名為springmvc.xml,同樣放在src目錄下 [html] view plain copy <?xml version='1.0' encoding='UTF-8'?> <beans xmlns='http://www./schema/beans' xmlns:xsi='http://www./2001/XMLSchema-instance' xmlns:mvc='http://www./schema/mvc' xmlns:context='http://www./schema/context' xsi:schemaLocation=' http://www./schema/beans http://www./schema/beans/spring-beans.xsd http://www./schema/mvc http://www./schema/mvc/spring-mvc.xsd http://www./schema/context http://www./schema/context/spring-context.xsd'> <!--1.開啟Springioc 自動(dòng)掃描注解包 --> <context:component-scan base-package='com.ssm'/> <!--2. 開啟注解 --> <mvc:annotation-driven /> <!--3.配置視圖解析器 --> <bean class='org.springframework.web.servlet.view.InternalResourceViewResolver'> <property name='prefix' value='/'></property> <property name='suffix' value='.jsp'></property> </bean> <!--4.注解映射器（可?。?nbsp; --> <!-- <bean class='org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping'></bean> --> <!--5.配置適配器（不需時(shí)可?。?nbsp; --> <!-- <bean class='org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter'> 在業(yè)務(wù)方法的返回值和權(quán)限之間使用@ResponseBody注解表示返回值對(duì)象需要轉(zhuǎn)成JSON文本 <property name='messageConverters'> <list> <bean class='org.springframework.http.converter.json.MappingJackson2HttpMessageConverter'/> </list> </property> </bean> --> </beans>
5、web.xml配置 [html] view plain copy <?xml version='1.0' encoding='UTF-8'?> <web-app xmlns:xsi='http://www./2001/XMLSchema-instance' xmlns='http://java./xml/ns/javaee' xsi:schemaLocation='http://java./xml/ns/javaee http://java./xml/ns/javaee/web-app_3_0.xsd' id='WebApp_ID' version='3.0'> <display-name>ssm</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!--Spring核心監(jiān)聽器 --> <!--在服務(wù)器啟動(dòng)時(shí)加載Spring容器，且只會(huì)加載一次 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param> <!--配置Springmvc核心控制器 --> <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:springmvc.xml</param-value> </init-param> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> <!--配置由Spring 提供的針對(duì)中文亂碼的編碼過濾器 --> <!-- 編碼過濾器 --> <filter> <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
6、持久層功能實(shí)現(xiàn) userDao.java （映射接口） [java] view plain copy package com.ssm.dao.user; import org.apache.ibatis.annotations.Param; import com.ssm.bean.User; /** * 持久層映射接口 * @author Nocol * */ public interface UserDao { //添加用戶 public void addUser(User user); //根據(jù)用戶名和密碼查詢用戶 //注解的兩個(gè)參數(shù)會(huì)自動(dòng)封裝成map集合，括號(hào)內(nèi)即為鍵 public void findUserByNameAndPwd(@Param('name')String name, @Param('password')String password); }
UserDao.xml （映射文件） [html] view plain copy <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE mapper PUBLIC '-////DTD Mapper 3.0//EN' 'http:///dtd/mybatis-3-mapper.dtd'> <mapper namespace='com.ssm.dao.user.UserDao'> <!--注意sql語句沒有分號(hào)結(jié)尾 --> <insert id='addUser' parameterType='User'> insert into t_user(id,name,password) values(#{id},#{name},#{password}) </insert> <!--注意這里的參數(shù)類型是parameterType而不是parameterMap，因?yàn)榉祷氐氖菃蝹€(gè)類型 --> <select id='findUserByNameAndPwd' parameterType='map' resultType='User'> select t.name,t.password from t_user t where name=#{name} and password=#{password} </select> </mapper>
7、業(yè)務(wù)層功能實(shí)現(xiàn) UserService.java [java] view plain copy package com.ssm.service; import com.ssm.bean.User; public interface UserService { //用戶注冊(cè) void regist(User user); //用戶登錄 void login(String name, String password); }
UserServiceImpl.java [java] view plain copy package com.ssm.service.Imp; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.ssm.bean.User; import com.ssm.dao.user.UserDao; import com.ssm.service.UserService; /** * 業(yè)務(wù)層 * @author Nocol * */ @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; @Override public void regist(User user) { // TODO Auto-generated method stub userDao.addUser(user); } @Override public void login(String name, String password) { // TODO Auto-generated method stub userDao.findUserByNameAndPwd(name,password); } }
8、控制層功能實(shí)現(xiàn) UserAction.java [java] view plain copy package com.ssm.controller.user; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import com.ssm.bean.User; import com.ssm.service.UserService; /** * 控制層 * @author Nocol * */ @Controller @RequestMapping('/user') public class UserAction { //注入Service @Autowired private UserService userService; @RequestMapping('regist') public String regist(User user,Model model){ System.out.println('用戶注冊(cè)：'+user.getName()+user.getPassword()); user.setId(1); userService.regist(user); model.addAttribute('msg', '注冊(cè)成功'); //注冊(cè)成功后跳轉(zhuǎn)success.jsp頁面 return 'success'; } @RequestMapping('login') public String login(String name,String password,Model model){ System.out.println('用戶登錄：'+name+password); /*Map<String, String> map=new LinkedHashMap<String,String>(); map.put('name', user.getName()); map.put('password', user.getPassword());*/ userService.login(name,password); model.addAttribute('msg', '登錄成功'); return 'success'; } }
9、jsp頁面實(shí)現(xiàn) regist.jsp [javascript] view plain copy <%@ page language='java' contentType='text/html; charset=UTF-8' pageEncoding='UTF-8'%> <!DOCTYPE html PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www./TR/html4/loose.dtd'> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> <title>用戶注冊(cè)</title> </head> <body> <form action='${pageContext.request.contextPath }/user/regist.action'> <table border='1'> <tr> <td>用戶名</td> <td><input type='text' name='name'></td> </tr> <tr> <td>密碼</td> <td><input type='text' name='password'></td> </tr> <tr> <td><input type='submit' value='注冊(cè)'></td> </tr> </table> </form> </body> </html>
login.jsp [javascript] view plain copy <%@ page language='java' contentType='text/html; charset=UTF-8' pageEncoding='UTF-8'%> <!DOCTYPE html PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www./TR/html4/loose.dtd'> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> <title>用戶登錄</title> </head> <body> <form action='${pageContext.request.contextPath }/user/login.action'> <table border='1'> <tr> <td>用戶名</td> <td><input type='text' name='name'></td> </tr> <tr> <td>密碼</td> <td><input type='text' name='password'></td> </tr> <tr> <td><input type='submit' value='登錄'></td> </tr> </table> </form> </body> </html>
success.jsp [javascript] view plain copy <%@ page language='java' contentType='text/html; charset=UTF-8' pageEncoding='UTF-8'%> <!DOCTYPE html PUBLIC '-//W3C//DTD HTML 4.01 Transitional//EN' 'http://www./TR/html4/loose.dtd'> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> <title>登錄成功</title> </head> <body> ${msg }</br> <a href='${pageContext.request.contextPath }/login.jsp'>去登錄</a> </body> </html>
