eclipse+maven搭建ssm

1）Windows 7 旗舰版

2）JDK 1.8.0_131

3）Eclipse Java EE IDE for Web Developers  Version: Neon.3 Release (4.7.3)

4）Tomcat 8.5

1、下载maven，配置maven环境变量。

maven的下载地址：http://maven.apache.org/download.cgi

解压后放在D盘最好，因为我C盘安装的固态，所以我放在C盘了

配置maven环境变量，

在环境变量中，新增系统变量名：MAVEN_HOME，变量值：C:\apache-maven-3.5.3C:\apache-maven-3.5.3

在Path中追加：%MAVEN_HOME%\bin;

在命令行窗口中输入：mvn –v，如果看见下图则说明maven安装配置完毕

2、设置eclipse自带maven整合工具，在Preferences中找到Maven节点，观察User Settings项的设置是否正确

点击Installations节点，添加maven runtime

我的已经配置过了。所以显示名字重复错误。

3、创建maven项目，

创建出的maven项目如下图

在eclipse中设置Server为Tomcat，注意JRE设置为安装的JDK的jre

添加tomcat

在项目上右键，查看项目信息

默认的Dynamic Web Module为2.3，使用Tomcat 8.5，需要修改为3.1

修改方法：

① maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml

将下图的2.3改成3.1

② maven工程下的web.xml文件修改为

③ pom.xml文件中修改build节点，添加如下内容

       
              org.apache.maven.plugins
              maven-compiler-plugin
              
                     1.8
                     1.8
              
       

④ 修改后，在项目上右键，找到Maven属性下的Update Project，点击

⑤ 选择该项目进行更新，如果怕不能强制更新，可以勾选Force Update of Snapshots/Releases

⑥ 点击OK后更新maven项目，再观察项目属性，Module已经变为3.1

4、下载ssm框架所需jar包

5、完善项目结构

因为服务端maven项目的标准结构有四个子包：src/main/java、src/main/resources、src/test/java、src/test/resources，这里缺少了src/test/resources，所以手动补上。

在项目中新建Source Folder

创建src/test/resources目录后，工程如下图所示

6、具体文件代码

UserDao.java

package cn.temptation.dao;

import cn.temptation.domain.User;

public interface UserDao {
	  public abstract User findByUsername(String username);
}

 

UserMapper.xml

    
        SELECT * FROM userinfo WHERE username=#{username}
    

User.java

package cn.temptation.domain;

public class User {

	  private Integer userid;
	    private String username;
	    private String password;

	    // 构造函数
	    public User() {
	        super();
	    }

	    public User(Integer userid, String username, String password) {
	        super();
	        this.userid = userid;
	        this.username = username;
	        this.password = password;
	    }

	    // 成员方法
	    public Integer getUserid() {
	        return userid;
	    }

	    public void setUserid(Integer userid) {
	        this.userid = userid;
	    }

	    public String getUsername() {
	        return username;
	    }

	    public void setUsername(String username) {
	        this.username = username;
	    }

	    public String getPassword() {
	        return password;
	    }

	    public void setPassword(String password) {
	        this.password = password;
	    }
	}

UserController.java

package cn.temptation.web;

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import cn.temptation.dao.UserDao;
import cn.temptation.domain.User;

@Controller
@RequestMapping(value = "/user")
public class UserController {
    @Resource
    private UserDao userDao;

    @RequestMapping("/view")
    public String view() {
        return "main/login";
    }

    @RequestMapping("/indexview")
    public String index() {
        return "main/index";
    }

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public ModelAndView login(User model, HttpSession session) {
        User user = userDao.findByUsername(model.getUsername());

        if (user == null || !user.getPassword().equals(model.getPassword())) {
            return new ModelAndView("redirect:/login.jsp");
        } else {
            session.setAttribute("user", user);
            ModelAndView mav = new ModelAndView();
            mav.setViewName("index");
            return mav;
        }
    }
}
