1.在pom.xml中替换如下的内容

2.在“resources”文件中添加jdbc.properties、log4j.properties、spring-mvc.xml、spring-mybatis.xml
(1) jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver #jdbc.url=jdbc:mysql://localhost:3306/guoanyaoyejdbc.url=jdbc\:mysql\://localhost\:3306/guoanyaoye?useUnicode\=true&characterEncoding\=utf-8jdbc.username=rootjdbc.password=1234#\u5B9A\u4E49\u521D\u59CB\u8FDE\u63A5\u6570 jdbc.initialSize=0 #\u5B9A\u4E49\u6700\u5927\u8FDE\u63A5\u6570 jdbc.maxActive=20 #\u5B9A\u4E49\u6700\u5927\u7A7A\u95F2 jdbc.maxIdle=20 #\u5B9A\u4E49\u6700\u5C0F\u7A7A\u95F2 jdbc.minIdle=1 #\u5B9A\u4E49\u6700\u957F\u7B49\u5F85\u65F6\u95F4 jdbc. jdbc.maxWait=60000(2)log4j.properties

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><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> <!-- 单点登录 --> <!--<filter>--> <!--<filter-name>CAS Authentication Filter</filter-name>--> <!--<filter-class>org.jasig.cas.client.authentication.AuthenticationFilter</filter-class>--> <!--<init-param>--> <!--<param-name>casServerLoginUrl</param-name>--> <!--<param-value>https://cas.mydomain.com/cas/login</param-value>--> <!--</init-param>--> <!--<init-param>--> <!--<param-name>serverName</param-name>--> <!--<param-value>http://localhost:8084</param-value>--> <!--</init-param>--> <!--</filter>--> <!--<filter>--> <!--<filter-name>CAS Validation Filter</filter-name>--> <!--<filter-class>org.jasig.cas.client.validation.Cas10TicketValidationFilter </filter-class>--> <!--<init-param>--> <!--<param-name>casServerUrlPrefix</param-name>--> <!--<param-value>https://cas.mydomain.com/cas</param-value>--> <!--</init-param>--> <!--<init-param>--> <!--<param-name>serverName</param-name>--> <!--<param-value>http://localhost:8084</param-value>--> <!--</init-param>--> <!--<init-param>--> <!--<param-name>redirectAfterValidation</param-name>--> <!--<param-value>true</param-value>--> <!--</init-param>--> <!--</filter>--> <!--<filter>--> <!--<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>--> <!--<filter-class>org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class>--> <!--</filter>--> <!--<filter-mapping>--> <!--<filter-name>CAS Authentication Filter</filter-name>--> <!--<url-pattern>/*</url-pattern>--> <!--</filter-mapping>--> <!--<filter-mapping>--> <!--<filter-name>CAS Validation Filter</filter-name>--> <!--<url-pattern>/*</url-pattern>--> <!--</filter-mapping>--> <!--<filter-mapping>--> <!--<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>--> <!--<url-pattern>/*</url-pattern>--> <!--</filter-mapping>--> <session-config> <session-timeout> 30 </session-timeout> </session-config> <!-- 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>5.在main下创建java文件夹，再创建com、ssm,并创建controller、dao、entity、mapper、service每个层所在的package
6.在mapper下创建AdminMapper.xml
<?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.ssm.dao.IAdminDao"> <resultMap id="BaseResultMap" type="com.ssm.entity.Admin" > <id column="id" property="id" jdbcType="BIGINT" /> <result column="admin_name" property="adminName" jdbcType="VARCHAR" /> <result column="admin_pwd" property="adminPwd" jdbcType="VARCHAR" /> </resultMap> <select id="selectByNameAndPwd" resultMap="BaseResultMap" parameterType="java.lang.String" > select * from admin where admin_name = #{adminName} and admin_pwd = #{adminPwd} </select></mapper>7.在entity创建Admin
package com.ssm.entity;public class Admin { private long id; private String adminName; private String adminPwd; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getAdminName() { return adminName; } public void setAdminName(String adminName) { this.adminName = adminName; } public String getAdminPwd() { return adminPwd; } public void setAdminPwd(String adminPwd) { this.adminPwd = adminPwd; } }8.在dao层下创建IAdminDao
package com.ssm.dao;import java.util.List;import org.apache.ibatis.annotations.Param;import com.ssm.entity.Admin;public interface IAdminDao { List<Admin> selectByNameAndPwd(@Param("adminName") String adminName, @Param("adminPwd") String adminPwd);}9.在service层下新建impl包，并创建AdminService
package com.ssm.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.ssm.dao.IAdminDao;import com.ssm.entity.Admin;import com.ssm.service.IAdminService;@Service("adminService")public class AdminService implements IAdminService{ @Autowired private IAdminDao adminDao; public Admin getByNameAndPwd(String adminName,String adminPwd){ return adminDao.selectByNameAndPwd(adminName, adminPwd).get(0); }}10.在service层下创建IAdminService
package com.ssm.service;import com.ssm.entity.Admin;public interface IAdminService { Admin getByNameAndPwd(String adminName, String adminPwd);
}
11在controller层下创建AdminController
package com.ssm.controller;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.ssm.entity.Admin;
import com.ssm.service.IAdminService;
@Controller
@RequestMapping("/admin")
public class AdminController {
@Resource
private IAdminService adminService;
@RequestMapping("/showUser")
public String toIndex(HttpServletRequest request, Model model) {
System.out.println("-----------------------------------------------------------------");
// int userId = Integer.parseInt(request.getParameter("id"));
Admin user = adminService.getByNameAndPwd("1", "1");
model.addAttribute("user", user);
return "showUser";
}
}
