Maven+ssm框架简单增删改查
语录：在开发一个项目时，一定要注意细节，谨慎严密，多查多问，保持足够耐心。
世上无难事，只怕有心人
一：创建一个Maven项目
注意: 1.Build Path-Configure Build Path 修改成对应的jdk版本
二：pom.xml导入相应的包

三.spring-mvc.xml文件配置
四.创建generatorConfig.xml文件并maven-build
五.在eclipse对generatorConfig.xml进行Maven-build，生成表对应的model以及dao接口以及配置文件
代码就不写下来了
六.整合mabaties，在spring-mabaties.xml文件中配置事务
七.配置日志文件log4j.properties和common-logging.properties,以及jdbc.properties
1.log4j.properties

2.common-logging.properties
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
3.jdbc.properties
#创建连接
driverClassName=com.mysql.jdbc.Driver
#地址
url=jdbc:mysql://localhost:3306/mysql
#用户名
username=root
#密码
password=199701
##以下可以不配
#初始化连接
initialSize=10
#最大连接数量
maxActive=300
#最大空闲连接
maxIdle=20
#最大空闲连接
minIdle=1
#等待时间
maxWait=60000
八.配置web.xml
spring_fate
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath:spring-mybatis.xml,classpath:spring-mvc.xml
springMVC
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:spring-mybatis.xml,classpath:spring-mvc.xml
1
springMVC
/
org.springframework.web.util.IntrospectorCleanupListener
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding
UTF-8
forceEncoding
true
encodingFilter
/*
index.html
index.htm
index.jsp
default.html
default.htm
default.jsp
九.建立service以及service实现（Userservice.java UserserviceImpl)
package com.test.service;
import java.util.List;
import model.User2;
public interface UserService {
void insert(User2 user2);
boolean update(User2 user2);
boolean delete(int user2Id);
User2 select(int user2Id);
List findAll();
}
package com.test.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import dao.User2Mapper;
import model.User2;
@Service
@Transactional
//此处不再进行创建SqlSession和提交事务，都已交由spring去管理了。
public class UserServiceImpl implements UserService {
@Resource
private User2Mapper mapper;
public void insert(User2 user2) {
mapper.insert(user2);
}
public boolean update(User2 user2) {
return mapper.update(user2);
}
public boolean delete(int user2Id) {
return mapper.delete(user2Id);
}
public User2 select(int user2Id) {
User2 user2=mapper.select(user2Id);
return user2;
}
public List findAll() {
List findlist=mapper.findAll();
return findlist;
}
} 十.建立控制层(Usercontroller.java)
package com.test.controller;
import java.util.List;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.ibatis.reflection.SystemMetaObject;
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.test.service.UserService;
import model.User2;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
/**
* 获取所有用户列表
*
* @param request
* @return
*/
@RequestMapping("/getAllUser")
public String getAlluser(HttpServletRequest request, Model model) {
List user = userService.findAll();
System.out.println(user);
model.addAttribute("userlist", user);
request.setAttribute("userlist", user);
return "/allUser";
}
/**
* 跳转到添加用户界面
*
* @param request
* @return
*/
@RequestMapping("/toAddUser")
public String toAddUser() {
return "/addUser";
}
/**
* 添加用户并重定向
*
* @param user
* @param request
* @return
*/
@RequestMapping("/addUser")
public String addUser(User2 user, Model model) {
userService.insert(user);
return "redirect:/user/getAllUser";
}
/*
* 编辑用户
*
* @param user
*
* @param request
*
* @return
*/
@RequestMapping("/updateUser")
public String updateUser(User2 user2, HttpServletRequest request, Model model) {
if (userService.update(user2)) {
user2 = userService.select(user2.getUser2Id());
request.setAttribute("user", user2);
model.addAttribute("user", user2);
return "redirect:/user/getAllUser";
} else {
return "/error";
}
}
/*
* 根据id查询单个用户
*
* @param id
*
* @param request
*
* @return
*/
@RequestMapping("/getUser")
public String getUser(int id, HttpServletRequest request, Model model) {
request.setAttribute("user", userService.select(id));
model.addAttribute("user", userService.select(id));
return "/editUser";
}
/**
* 删除用户
*
* @param id
* @param request
* @param response
*/
@RequestMapping("/delUser")
public String delUser(int id, HttpServletRequest request, HttpServletResponse response) {
String result = "/error";
if(userService.delete(id)){
result = "forward:/user/getAllUser";
}
return result;
}
} 十一.创建视图层(index.jsp,addUser,allUser,editUser)
1.index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path=request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
首页
进入用户管理系统
2.allUser.jsp
<%@ page language="java" import="java.util.*" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path=request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort() + path + "/";%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
用户列表
添加用户
姓名
职位
操作
${user1.userName }
${user1.passWord }
编辑
删除
3.editUser.jsp
<%@ page language="java" import="java.util.*" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path=request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort() + path + "/";%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
编辑用户
4.addUser.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path=request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort() + path + "/";%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
添加用户
添加用户
以上就是所有代码，目录如下
需要从外导入的有 jQuery-3.31.min.js
数据库如下:
