自己没有一步步去搭框架,也是看了别人之后才明白了一些。非常感谢那个人。
一、准备环境:
maven:apache-maven-3.2.3
jdk:jdk1.8.0_25
tomcat:tomcat-6.0.37
二、配置Maven、jdk
1、Window——>Preferences——>Maven——>设置自己的Settings
2、Window——>Preferences——>Java——>Installed JREs——>Add
配置好maven之后,就可以在本地设置好的地方看到对应的Maven文件了,还有包含resp文件夹
三、新建Maven项目:
1、右击——>New(或者是File——>New)——>other——>Maven——>Maven Project——>Next
2、这时候,我们就成功创建出一个Maven项目了,项目结构如下图:
3、右击项目,选择Properties进行一些配置:
到这里,我们的Maven项目就建好了,接下来,我们来整合搭建SSM(spring MVC + Spring + Mybatis)
首先我们来配置一些整合框架所必须要的jar包,也就是来配置我们的pom文件,然后直接alt+f5,保存后,就会自动下载,存放在之前配置好的本地maven仓库中。

2、在src/main/resources下添加配置文件:applicationContext.xml:

- <context:component-scan base-package="com.ssm" />
- <import resource="spring-dao.xml"/>
- <import resource="spring-db.xml"/>
- <import resource="spring-tx.xml"/>
- beans>
配置数据库连接池:jdbc.properties
- driver=com.mysql.jdbc.Driver
- url=jdbc:mysql://localhost:3306/maven_ssm
- username=root
- password=root
- #定义初始连接数
- initialSize=0
- #定义最大连接数
- maxActive=20
- #定义最大空闲
- maxIdle=20
- #定义最小空闲
- minIdle=1
- #定义最长等待时间
- maxWait=60000
配置日志:log4j.properties
- #定义LOG输出级别
- log4j.rootLogger=INFO,Console,File
- #定义日志输出目的地为控制台
- log4j.appender.Console=org.apache.log4j.ConsoleAppender
- log4j.appender.Console.Target=System.out
- #可以灵活地指定日志输出格式,下面一行是指定具体的格式
- log4j.appender.Console.layout = org.apache.log4j.PatternLayout
- log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
- #文件大小到达指定尺寸的时候产生一个新的文件
- log4j.appender.File = org.apache.log4j.RollingFileAppender
- #指定输出目录
- log4j.appender.File.File = logs/ssm.log
- #定义文件最大大小
- log4j.appender.File.MaxFileSize = 10MB
- # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
- log4j.appender.File.Threshold = ALL
- log4j.appender.File.layout = org.apache.log4j.PatternLayout
- log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
配置我们的ioc注入:spring-dao.xml

到这里,我们的ssm框架就完成了,下面,我们来个实现:
在src/main/java下分别添加我们的dao包,service包,还有controller包.包里面添加相应的类,效果图如下:
UserController.java:
- package com.ssm.controller;
- import java.util.List;
- 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.dto.User;
- import com.ssm.service.IUserService;
- @Controller
- @RequestMapping("/user")
- public class UserController {
- @Resource
- private IUserService userService;
- @RequestMapping("/userList")
- public String userList(HttpServletRequest request,Model model){
- List
uList = userService.getAllUser(); - model.addAttribute("uList", uList);
- return "userList";
- }
- @RequestMapping("/showUser")
- public String showUser(HttpServletRequest request,Model model){
- int userId = Integer.parseInt(request.getParameter("id"));
- User user = userService.getUserById(userId);
- model.addAttribute("user", user);
- return "showUser";
- }
- @RequestMapping("/addUserUI")
- public String addUserUI(){
- return "addUser";
- }
- @RequestMapping("/addUser")
- public String addUser(HttpServletRequest request,Model model){
- User user = new User();
- user.setName(String.valueOf(request.getParameter("name")));
- user.setPassword(String.valueOf(request.getParameter("password")));
- user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));
- userService.addUser(user);
- return "redirect:/user/userList";
- }
- }
IUserDao.java:
- package com.ssm.dao;
- import java.util.List;
- import java.util.Map;
- import com.ssm.dto.User;
- public interface IUserDao {
- public User queryByPrimaryKey(Integer id);
- public List
queryUserByBatch(Map params); - public void insertUser(User user);
- public void insertUserByBatch(List
list); - public void deleteByPrimaryKey(Integer id);
- public void delteUserByBatch(Map
params); - public void updateByPrimaryKey(Integer id);
- public List
getAllUser(); - }
User.java:
- package com.ssm.dto;
- public class User {
- private Integer id;
- private String name;
- private String password;
- public Integer getId() {
- return id;
- }
- public void setId(Integer id) {
- this.id = id;
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPassword() {

- }
- public void setPassword(String password) {
- this.password = password == null ? null : password.trim();
- }
- }

IUserService.java:
- package com.ssm.service;
- import java.util.List;
- import com.ssm.dto.User;
- public interface IUserService {
- public User getUserById(int userId);
- public void insertUser(User user);
- public void addUser(User user);
- public List
getAllUser(); - }
UserServiceImpl.java:
- package com.ssm.service.Impl;
- import java.util.List;
- import javax.annotation.Resource;
- import org.springframework.stereotype.Service;
- import com.ssm.dao.IUserDao;
- import com.ssm.dto.User;
- import com.ssm.service.IUserService;
- @Service("userService")
- public class UserServiceImpl implements IUserService {
- @Resource
- private IUserDao userDao;
- public User getUserById(int userId) {
- return userDao.queryByPrimaryKey(userId);
- }
- public void insertUser(User user) {
- userDao.insertUser(user);
- }
- public void addUser(User user) {
- userDao.insertUser(user);
- }
- @Override
- public List
getAllUser() { - return userDao.getAllUser();
- }
- }
接下来就是我们的静态页面了jsp文件了,在WEB-INF文件夹下新建jsp文件夹,添加userinfo.jsp
userinfo.jsp:
- <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
- <%
- String path = request.getContextPath();
- String basePath=request.getSSScheme()+"://request.getServerName()"+":"+request.getServerPort+Path+
- "/"%>
- >
- <html>
- <head>
- <base href="<%=basePath%>">
- <title>My JSP 'userinfo.jsp' starting pagetitle>
- <meta http-equiv="pragma" content="no-cache">
- <meta http-equiv="cache-control" content="no-cache">
- <meta http-equiv="expires" content="0">
- <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
- <meta http-equiv="description" content="This is my page">
- head>
- <body>
- <form id="addUser" action="user/addUser" method="post">
- userName: <input id="name" name="name" /><br/>
- password: <input id="password" name="password" /><br/>
- <input type="submit" value="添加新用户"/>
- form>
- body>
- html>
哦,忘记配置tomcat,配置一下tomcat,然后部署发布项目,进行测试
到此,框架成
