ssm简单增删改查案例

此文章仅供新手参考或老手温习

一、创建maven web项目，这里就不多讲了.

二、添加pom文件信息

  	4.3.10.RELEASE
  	2.6
  	1.2
  	3.4.5
  	1.3.1
  	5.1.10
  	1.0.14
  	1.2.17
  	1.2
  	2.2
  	3.1.0
  	1.8.13
  
  
  
  	
  		org.springframework
  		spring-core
  		${spring.version}
  	
  	
  		org.springframework
  		spring-beans
  		${spring.version}
  	
  	
  		org.springframework
  		spring-context
  		${spring.version}
  	
  	
  		org.springframework
  		spring-web
  		${spring.version}
  	
  	
  		org.springframework
  		spring-webmvc
  		${spring.version}
  	
  	
  		org.springframework
  		spring-tx
  		${spring.version}
  	
  	
  		org.springframework

  		commons-logging
  		${commons-logging.version}
  	
  	
  		org.mybatis
  		mybatis
  		${mybatis.version}
  	
  	
  		org.mybatis
  		mybatis-spring
  		${mybatis-spring.version}
  	
  	
  		mysql
  		mysql-connector-java
  		${mysql.version}
  	
  	
  		com.alibaba
  		druid
  		${druid.version}
  	
  	
  		log4j
  		log4j
  		${log4j.vresion}

  	
  	
  		jstl
  		jstl
  		${jstl.version}
  	
  	
  		javax.servlet.jsp
  		jsp-api
  		${jsp-api.version}
  	
  	
  		javax.servlet
  		javax.servlet-api
  		${servlet-api.version}
  	
  	
  		org.aspectj

  		${aspectjweaver.version}
  	
  	
  	
  	
	    org.apache.maven.plugins
	    maven-resources-plugin
	    2.5
	
  

三、添加web.xml文件信息

        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
        
            forceEncoding
            true
        
    
     
         encodingFilter
         /*
     
     
     
	
		contextConfigLocation
		classpath:spring/spring-*.xml
	

	
		org.springframework.web.context.ContextLoaderListener
	
  
	
		springDispatcherServlet
		org.springframework.web.servlet.DispatcherServlet
		
			contextConfigLocation
			classpath:spring/springmvc.xml
		
		1
	

	
		springDispatcherServlet
		/
	

四、springmvc.xml

五、spring-dao.xml

六、spring-service.xml

七、database.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

八、Java代码部分

1.PageController

@Controller
public class PageController {

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

2.UserController

@Controller
@RequestMapping("/users")
public class UsersController {

	@Autowired
	private UserService userServie;
	
	@RequestMapping("/toAddUser")
	public String toAddUser() {
		return "addUser";
	}
	
	@RequestMapping("/toUpdateUser/{uid}")
	public String toUpdateUser(@PathVariable("uid")Integer uid,Map map) {
		if(uid != null) {
			try {
				Users users = userServie.findOne(uid);
				map.put("user", users);
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
		return "updateUser";
	}
	
	@RequestMapping("/userinfo")
	public String user(Map map) {
		List findAll = userServie.findAll();
		map.put("userList", findAll);
		return "userinfo";
	}
	
	@RequestMapping("/addUser")
	@ResponseBody
	public String addUser(Users users) {
		if(users != null) {
			try {
				userServie.addUsers(users);
				return "success";
			} catch (Exception e) {
				e.printStackTrace();
				return "error";
			}
		}else {
			return "not null";
		}
	}
	
	@RequestMapping("/updateUser")
	@ResponseBody
	public String updateUser(Users users) {
		if(users != null) {
			try {
				userServie.updateUsers(users);
				return "success";
			} catch (Exception e) {
				e.printStackTrace();
				return "error";
			}
		}else {
			return "not null";
		}
	}
	
	@RequestMapping("/deleteUser/{uid}")
	@ResponseBody
	public String deleteUser(@PathVariable("uid")Integer uid) {
		if(uid != null) {
			try {
				userServie.deleteUsers(uid);
				return "success";
			} catch (Exception e) {
				e.printStackTrace();
				return "error";
			}
		}else {
			return "not null";
		}
	}
}

3.实体类

public class Users {
    private Integer uid;

    private String name;

    private String username;

    private String password;

    private String gender;

    private Integer age;

    private Date createdate;

    private Date lastlogindate;

    private Integer locked;
    
    get set.......
}

4.service和mapper就不贴出来了（mybatis逆向工程就可以直接搞定mapper和pojo）

九、JSP部分

  1.userinfo.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>








	
Show User
	

	
		
<%-- 			 --%>
			
<%-- 			 --%>
			

		


			
name
			
username

			
gender
			
age
			
createDate
			
lastLoginDate
			
locked
			
操作
		
		
${user.uid}
${user.name}
			
${user.username}
${user.password}
${user.gender}
			
${user.age}
			

			

			
${user.locked}
			
删除
		
		
	
	
	

2.其他JSP页面就只是画页面而已就不贴了

十、最后完整的项目结构
