Eclipse+maven SSM框架整合 Eclipse+Maven整合SSM SSM（Spring+SpringMVC+MyBatis）框架集由Spring、MyBatis两个开源框架整合而成（SpringMVC是Spring中的部分内容）。常作为数据源较简单的web项目的框架。（一）用Eclipse创建Maven项选择使用骨架 maven-archetype-webapp ，这是我们创建一个Web 比较常用的骨架，然后下一步。 GroupID 是项目组织唯一的标识符，一般来说可以设置的与包结构一致，也就是 main 目录里java 的目阅读详情

Eclipse+Maven+SSM整合

一、准备工作：
maven：apache-maven-3.2.3
jdk：jdk1.8.0_25
tomcat：tomcat-8.5
MySQL- 5.7

二、细节准备：
1.调整Dynamic Web Module 版本
maven自带的Dynamic Web Module版本是2.3，需要修改成Dynamic Web Module 3.0版本（创建更完整的web项目结构）
步骤：
1.1：创建一个maven web 工程
在这里插入图片描述
1.2：选中项目名称，右击选择Proprities选项，进入：

这里显示Dynamic Web Module 为2.3，java版本为1.5，但是我们用的是1.8，所以可以先改过来，同时把Dynamic Web Module前面的选项去掉，然后点击Apply应用一下。

接下来，再勾选中Dynamic Web Module，先不要着急点Apply
在这里插入图片描述
点击Further configuration available 输入src/main/webapp 并选中复选框

1.3:注意jre使用的版本

修改方式：

接着配置Build build path 和java compiler ,都设置为JDK1.8,点击Apply and close.

问题：关于创建的maven web工程Java Resources 一直出现红色小叉号
在这里插入图片描述
解决方式：
第一步：首先使用cmd查看自己的jdk版本

第二步：打开项目属性，

第三步：修改完错误还在，就选择更新项目，选中项目名，右击选择maven选项，

修改完基本上就没有了红色叉号了。

如果还是有错误，接下来是解决办法：

打开windows–>show view–> problems
在这里插入图片描述

Description	                                                        Resource	Path	Location	Type
Cannot change version of project facet Dynamic Web Module to 2.5.	cms-web		line 1	Maven Java EE C

错误的原因大概是当前web.xml版本是2.5而maven的web.xml的版本是2.3所以会提示版本不一致
解决方式也很简单：
创建普通的web项目在创建的时候选择web版本为3.0（因为项目中选择的是3.0）
在这里插入图片描述
然后把当前创建web.xml复制放在maven项目的web-info里面，刷新项目，错误就会消失

另外一种解决方式：maven项目升级为3.0
在这里插入图片描述

然后在eclipse里右键该工程–maven–updateProject即可。这时候项目有可能报红x，打开windows–>show view–> problems错误信息为

Dynamic Web Module 3.0 requires Java 1.6 or newer.

解决方式：
直接选中项目，选择properties选项，

在项目的pom.xml的标签中加入：（可以不添加）

<plugins>  
    <plugin>  
        <groupId>org.apache.maven.plugins</groupId>  
        <artifactId>maven-compiler-plugin</artifactId>  
        <version>2.3.2</version>  
        <configuration>  
            <source>1.6</source>  
            <target>1.6</target>  
        </configuration>  
    </plugin>  
</plugins>

1.4：注意项目的编码问题：
在这里插入图片描述

到这里，Maven项目就建好了，接下来，我们来整合搭建SSM（Spring MVC + Spring + Mybatis）

2.整合ssm

创建一个maven web基本框架，接下来就是配置pom.xml，导入相关的jar文件
第一步：
pom.xml

第二步：
在src/main/resources文件夹下创建配置文件
在这里插入图片描述
具体的配置属性：注意配置文件名尽量不改动，不然配置文件中的一些位置需要改动
applicationContext.xml

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/实例名
jdbc.username=root
jdbc.password=1234

到这基本上所有的属性文件的配置就已经完成了，接下来就是配置相关的测试实例
这里给出一个基本的例子，在src/main/java文件夹下创建如下
在这里插入图片描述
具体代码如下：
dao层的Admindao.java,这里一般不需要进行注解

package org.tele.dao;
import org.tele.entity.Admin;
public interface AdminDao {	
	public  Admin selectAdmin(Admin admin);
}

mapper层的映射文件admindao.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="org.tele.dao.AdminDao" >
	<select id="selectAdmin"  resultType="Admin">
		select * from tc_admin where aname=#{aname} and password=#{password}
	</select>
</mapper>

service层的adminService接口

package org.tele.service;
import org.tele.entity.Admin;
public interface AdminService {	
		public Admin selectAdmin(Admin admin);
}

service的实现类adminServiceImpl.java

package org.tele.service.impl;

import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import org.tele.dao.AdminDao;
import org.tele.entity.Admin;
import org.tele.service.AdminService;
@Service
public class AdminServiceImpl implements AdminService {

	@Resource
	private AdminDao admindao;
	
	@Override
	public Admin selectAdmin(Admin admin) {
		// TODO Auto-generated method stub
		Admin adm=admindao.selectAdmin(admin);
		System.out.println(adm);
		return adm;
	}
}

controller层的AdminController.java

package org.tele.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.tele.entity.Admin;
import org.tele.service.AdminService;

@Controller
public class AdminController {
	@Resource //依赖注入，注入service
	private AdminService adminservice;
	
	@RequestMapping("/login.do")
	public String login(Admin admin,HttpServletRequest request){
		Admin admin1=(Admin) adminservice.selectAdmin(admin);
		System.out.println(admin1);
		if(admin1==null){
			request.setAttribute("admin", admin);
			request.setAttribute("msg", "用户名或密码错误");
			return "login";
		}else{
			HttpSession session = request.getSession();
			session.setAttribute("rightadmin", admin1);
			return "success";
		}
		}
}

最后是一些调试的简单页面内容
在这里插入图片描述
login.jsp的内容

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"  prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Login</title>
<script type="text/javascript" src="./WEB-INF/assets/js/jquery-3.4.1.min.js"></script>
</head>
<body>
<form action="${pageContext.request.contextPath}/login.do" method="post">
	username:<input type="text" name="aname" value="${admin.aname}"><br>
	password:<input type="password" name="password" value="${admin.password }"><br>
	<input type="submit" value="login"><font color="red">${msg}</font>
</form>
</body>
</html>

下面是跳转成功的显示页面success.jsp的内容

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core"  prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
Welcom to Login!${rightadmin.aname}
