ssm(spring4+springmvc4+mybatis3)maven环境搭建

1、创建maven项目，webapp。把下面依赖复制到pom.xml文件中

          
              
            4.0.2.RELEASE  
              
            3.2.6  
              
            1.7.7  
            1.2.17  
          
      
          
              
                junit  
                junit  
                4.11  
                  
                test  
              
              
              
                org.springframework

                org.springframework  
                spring-tx  
                ${spring.version}  
              
      
              
                org.springframework  
                spring-jdbc  
                ${spring.version}  
              
      
              
                org.springframework  
                spring-webmvc  
                ${spring.version}  
              
              
                org.springframework  
                spring-aop  
                ${spring.version}

                log4j  
                log4j  
                ${log4j.version}  
              
              
              
              
              
                com.alibaba

                1.1.41  
              
      
      
              
                org.slf4j  
                slf4j-api  
                ${slf4j.version}

                1.9.13  
              
              
              
                commons-fileupload  
                commons-fileupload  
                1.3.1

                commons-codec  
                1.9  
                           
          

2、创建jdbc.properties文件，配置MySQL数据库的基本信息

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/erp2
username=root
password=123456

3、修改web.xml文件

  
 
  Archetype Created Web Application
     
        contextConfigLocation  
        classpath:applicationContext.xml  
      
      
      
        encodingFilter  
        org.springframework.web.filter.CharacterEncodingFilter  
          
            encoding  
            UTF-8  
          
      
      
        encodingFilter  
        *.action  
        *.do  
        *.view  
      
      
      
        org.springframework.web.context.ContextLoaderListener  
      
      
      
        org.springframework.web.util.IntrospectorCleanupListener  
      
  
      
      
        SpringMVC  
        org.springframework.web.servlet.DispatcherServlet  
          
            contextConfigLocation  
            classpath:spring-mvc.xml  
          
        1  
      
      
        SpringMVC  
          
        /  
      
      
        /index.jsp  
      
  

3、创建spring-mybatis.xml

3、创建spring-mvc.xml文件

   
      
      
      
      
          
              
                text/html;charset=UTF-8  
              
          
      
      
      
          
              
                   
              
          
      
      
      
          
          
          
      
      
      
        
          
            
          
            
          
            
       
  
  

4、创建log4j.xml

 log4j.rootLogger=INFO,Console,File
#\u5B9A\u4E49\u65E5\u5FD7\u8F93\u51FA\u76EE\u7684\u5730\u4E3A\u63A7\u5236\u53F0
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#\u53EF\u4EE5\u7075\u6D3B\u5730\u6307\u5B9A\u65E5\u5FD7\u8F93\u51FA\u683C\u5F0F\uFF0C\u4E0B\u9762\u4E00\u884C\u662F\u6307\u5B9A\u5177\u4F53\u7684\u683C\u5F0F  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
  
#\u6587\u4EF6\u5927\u5C0F\u5230\u8FBE\u6307\u5B9A\u5C3A\u5BF8\u7684\u65F6\u5019\u4EA7\u751F\u4E00\u4E2A\u65B0\u7684\u6587\u4EF6  
log4j.appender.File = org.apache.log4j.RollingFileAppender
#\u6307\u5B9A\u8F93\u51FA\u76EE\u5F55  
log4j.appender.File.File = logs/ssm.log
#\u5B9A\u4E49\u6587\u4EF6\u6700\u5927\u5927\u5C0F
log4j.appender.File.MaxFileSize = 10MB
# \u8F93\u51FA\u6240\u4EE5\u65E5\u5FD7\uFF0C\u5982\u679C\u6362\u6210DEBUG\u8868\u793A\u8F93\u51FADEBUG\u4EE5\u4E0A\u7EA7\u522B\u65E5\u5FD7  
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

5、创建applicationContext.xml

6、创建controller ，包名cn.zkz.controller

package cn.zkz.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 cn.zkz.pojo.EmpModel;
import cn.zkz.service.EmpService;

@Controller
@RequestMapping("/emp")
public class EmpController {
	@Resource  
    private EmpService empService;
	@RequestMapping("/showEmp")  
    public String toIndex(HttpServletRequest request,Model model){  
        long empUuid = Integer.parseInt(request.getParameter("id"));  
        EmpModel em = this.empService.getEmById(empUuid);
        model.addAttribute("em", em);  
        return "emp";  
    }   
}

7、service层

package cn.zkz.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import cn.zkz.dao.EmpDao;
import cn.zkz.pojo.EmpModel;
import cn.zkz.service.EmpService;

public class EmpServiceImpl implements EmpService{

	@Resource
    private EmpDao empDao;

	@Override
	public EmpModel getEmById(Long empUuid) {
		
		return this.empDao.selectByPrimaryKey(empUuid); 
	}

}

8、dao层

package cn.zkz.dao.impl;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;

import cn.zkz.dao.EmpDao;
import cn.zkz.pojo.EmpModel;

public class EmpDaoImpl implements EmpDao {

	private SqlSessionFactory sqlSessionFactory;
	public SqlSessionFactory getSqlSessionFactory() {
		return sqlSessionFactory;
	}
	public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
		this.sqlSessionFactory = sqlSessionFactory;
	}

	@Override
	public EmpModel selectByPrimaryKey(long empUuid) {

		// 创建SqlSession
		SqlSession sqlSession = this.sqlSessionFactory.openSession();

		// 根据id查询用户信息
		EmpModel em = sqlSession.selectOne("findUserById", empUuid);

		return em;
	}

}

9、pojo

package cn.zkz.pojo;

public class EmpModel {

	private Long uuid;
	private String username;
	private String password;
	private String name;
	private String tele;
	private Integer gerder;
	public Long getUuid() {
		return uuid;
	}
	public void setUuid(Long uuid) {
		this.uuid = uuid;
	}
	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;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTele() {
		return tele;
	}
	public void setTele(String tele) {
		this.tele = tele;
	}
	public Integer getGerder() {
		return gerder;
	}
	public void setGerder(Integer gerder) {
		this.gerder = gerder;
	}
	
	
}

10、EmpModelMapper.xml

	
	
	
		SELECT * FROM tbl_emp WHERE uuid= #{id}
