spring-springmvc-mybatis-maven整合的简单工程

本文主要介绍技术，新手专用，大神绕过

本文作者所用：所有东西的版本

MyEClipse 2016
Spring 4.0.2.RELEASE（最新）
Mybatis 3.2.8（最新）
1.maven工程的创建










第一次新建MAVEN项目的筒子，你们在这里要稍微等一哈，MAVEN要去下载依赖






选中上面的maven-archetype-webapp点击next






Group Id实际上生成的是公司包名,意义不大，Artifact Id是工程名称，输入完后点击Finish。

在main里添加java包，java代码就写到这里边，在webapp>WEB-INF下添加jsp，这里是jsp界面

spring、mybatis等的配置文件放在resources里边。如下，这是我加完东西后的工程






2.现在开始添加和修改配置文件

2.1首先是pom.xml。jar包的引入

<properties>
<spring.version>4.0.2.RELEASE</spring.version>
<!-- mybatis版本号 -->
<mybatis.version>3.2.8</mybatis.version>
<!-- log4j日志文件管理包版本 -->
<slf4j.version>1.7.12</slf4j.version>
<log4j.version>1.2.17</log4j.version>
</properties>

2.2 springmvc的配置

红色部分是需要注意的地方，第一个红色代码是指到你controller放置的地方，第二个红色是 你jsp页面的位置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

</beans>

2.3 mybatis配置文件

红色部分是你需要注意和根据自己工程来修改的地方，另外需要注意的是你在使用mysql数据库的时候需要配置dataSource里的红色配置，否则mysql在长时间不连接的时候（大约是2个小时左右），之后第一次连接会失败，之后就会正常。还有就是需要做回滚的时候，mysql数据库里的对应表的类型需要改为InnoDB，否则回滚不会生效。

<?xml version="1.0" encoding="UTF-8"?>

3. jdbc.properties的配置

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://130.13.10.236:3306/maven
username=maven
password=sj0729
#初始化连接大小
initialSize=20
#连接池最大数量
maxActive=100
#连接池最大空闲
maxIdle=30
#连接池最小空闲
minIdle=1
#获取连接最大等待时间
maxWait=20000

4.log4j.properties输出日志的配置

##############  PRODUCT ##############
#log4j.rootLogger=INFO,Console,File
##############  UAT  ####################
log4j.rootLogger=DEBUG,Console,File,BGController,FpResultServiceImpl

5.web.xml的配置

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

6.使用mybatis-generator-core-1.3.2自动生成相关的表信息

可自动生成dao,mapping,pojo文件将其导入到java.com.ys.maven中

生成工程可查看

http://blog.csdn.net/u014709028/article/details/56838798

7.创建service

在java中创建com.ys.maven.service包,创建IUserService的接口

public interface IUserService {
int deleteByPrimaryKey(Integer id);

int insert(User record);

int insertSelective(User record);

User selectByPrimaryKey(Integer id);

int updateByPrimaryKeySelective(User record);

int updateByPrimaryKey(User record);
}

com.ys.maven.service.impl包添加UserServiceImpl实现IUserService

@Service("userService")
public class UserServiceImpl implements IUserService{

@Resource
private UserMapper userMapper;

public int deleteByPrimaryKey(Integer id) {
// TODO Auto-generated method stub
return userMapper.deleteByPrimaryKey(id);
}

public int insert(User record) {
// TODO Auto-generated method stub
return userMapper.insert(record);
}

public int insertSelective(User record) {
// TODO Auto-generated method stub
return userMapper.insertSelective(record);
}

public User selectByPrimaryKey(Integer id) {
// TODO Auto-generated method stub
return userMapper.selectByPrimaryKey(id);
}

public int updateByPrimaryKeySelective(User record) {
// TODO Auto-generated method stub
return userMapper.updateByPrimaryKeySelective(record);
}

public int updateByPrimaryKey(User record) {
// TODO Auto-generated method stub
return userMapper.updateByPrimaryKey(record);
}

}

8.创建controller控制层

在java.com.ys.maven.controller中创建UserController.java

@Controller
@RequestMapping("/sys/user")
public class UserController extends BaseController{

@Resource
private IUserService userService;

@RequestMapping("/show")
public ModelAndView show(HttpServletRequest request, HttpServletResponse response) throws IOException {

User user = userService.selectByPrimaryKey(1);
Map<String, Object> map = new HashMap<String, Object>();
map.put("name", user.getName());

return new ModelAndView("show", map);
//show为跳转的jsp页面名称。对应WEB-INF/jsp/show.jsp
}
}

public class BaseController {
public static final String CMD_EDIT = "edit";
public static final String CMD_NEW = "new";
public static final String MODEL = "model";
protected String idField;
protected String statusField;
protected static ObjectMapper mapper = new ObjectMapper();
protected static JsonFactory factory = mapper.getJsonFactory();

protected void writeJSON(HttpServletResponse response, String json) throws IOException {
response.setContentType("text/html;charset=utf-8");
response.getWriter().write(json);
}

protected void writeJSON(HttpServletResponse response, Object obj) throws IOException {
response.setContentType("text/html;charset=utf-8");
JsonGenerator responseJsonGenerator = factory.createJsonGenerator(response.getOutputStream(), JsonEncoding.UTF8);
responseJsonGenerator.writeObject(obj);
}

}

9.创建view视图层

在WEB-INF/jsp文件夹中创建show.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'show.jsp' starting page</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->

</head>

<body>
${name}
</body>
</html>

最后工程的总的目录结构如下



10.项目测试

在tomcat上部署工程，输入如下url ，IP地址及端口号换成自己的






数据库中表的数据






ok数据显示正常，打完收工。
