一、准备

  • JAVA环境JDK1.7，官方下载地址：http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html


  • Tomcat环境Tomcat7，官方下载地址：http://tomcat.apache.org/download-70.cgi


  • Maven环境，官方下载地址：http://maven.apache.org/download.cgi


  • Eclipse，官方下载地址：http://www.eclipse.org/downloads/


  • Eclipse插件springsource-tool-suite

  • Eclipse插件mybatis generator

二、JDK安装与环境变量配置
教程：http://jingyan.baidu.com/article/6dad5075d1dc40a123e36ea3.html

三、Tomcat安装

 
四、Maven安装与eclipse配置
教程：http://jingyan.baidu.com/article/295430f136e8e00c7e0050b9.html

springsource-tool-suite所有版本下载地址： http://spring.io/tools/sts/all

六、创建test数据库，lgb_bigdata_user用户表
test数据库，默认已经创建
创建lgb_bigdata_user数据表 
CREATE TABLE `lgb_bigdata_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(20) DEFAULT '' COMMENT '用户名',
  `password` varchar(50) DEFAULT '' COMMENT '用户密码',
  `email` varchar(50) DEFAULT '' COMMENT '邮箱地址',
  `createtime` datetime DEFAULT NULL COMMENT '注册时间',
  `updatetime` datetime DEFAULT NULL COMMENT '修改时间',
  `status` tinyint(1) unsigned zerofill DEFAULT '0' COMMENT '状态 0禁用1正常',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户表';

七、mybatis generator eclipse插件的安装

mybatisGenrator.xml 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
 PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
 "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
	<context id="DB2Tables"	targetRuntime="MyBatis3">

	<table tableName="lgb_bigdata_user" domainObjectName="LgbBigdataUserEntity" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
	</context>
</generatorConfiguration>


八、eclipse搭建动态WEB项目
  1. 创建项目

    File -> New -> Dynamic Web project  填写项目名称 project name: springmvctest


    next -> remove src  -> add Folder -> src/main/java、src/main/resource、src/test/java、src/test/resource


    next -> 勾选Generate web.xml deployment descriptor -> finish

    下图springmvctest项目结构图

  2. 创建maven配置文件pom.xml

    springmvctest -> 右键 -> Configure -> Convert to Maven Project -> finish


    pom.xml
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  3. 数据库连接池配置文件，src/main/resource内创建jdbc.properties
    driver=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8
user=root
password=123456
idleConnectionTestPeriod=60
maxIdleTime=240
initialPoolSize=100
acquireIncrement=5
maxPoolSize=500
minPoolSize=10
  4. 日志配置文件，src/main/resource内创建log4j.properties
    # DEBUG,INFO,WARN,ERROR,FATAL
LOG_LEVEL=INFO

#C-console, I-INFO, E-ERROR
log4j.rootLogger=${LOG_LEVEL},C,I,E

log4j.appender.C=org.apache.log4j.ConsoleAppender
log4j.appender.C.Threshold = INFO
log4j.appender.C.Encoding=utf-8
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss} (%F:%L):%m%n

log4j.appender.I=org.apache.log4j.DailyRollingFileAppender
log4j.appender.I.File=${catalina.base}/logs/eidserver/info/log_daily
#log4j.appender.I.File=c://eidserver/info/log_daily
log4j.appender.I.Threshold = INFO	
log4j.appender.I.Append = true
log4j.appender.I.Encoding=utf-8
log4j.appender.I.DatePattern='_'yyyy-MM-dd'.log'
log4j.appender.I.layout=org.apache.log4j.PatternLayout
log4j.appender.I.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH\:mm\:ss} (%F\:%L)\:%m%n
log4j.appender.I.MaxFileSize = 50MB
log4j.appender.I.MaxBackupIndex = 7

log4j.appender.E=org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File=${catalina.base}/logs/eidserver/error/log_error
#log4j.appender.E.File=c://eidserver/error/log_error
log4j.appender.E.Append = TRUE

log4j.appender.E.layout=org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH\:mm\:ss} (%F\:%L)\:%m%n 
log4j.appender.E.MaxFileSize = 50MB
  5. src/main/resource内创建spring.xml
    <?xml version="1.0" encoding="UTF-8"?>

	</aop:config>

</beans>
  7. srpringmvc配置文件，spring-mvc.xml
    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="maxInMemorySize" value="40960" />
	</bean>
	</beans>
     
 
 

  8. 配置web.xml
  
<?xml version="1.0" encoding="UTF-8"?>
<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">
  <display-name>springmvctest</display-name>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>
  <servlet>
    <servlet-name>springMvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <error-page>
    <error-code>404</error-code>
    <location>/resources/views/404.jsp</location>
  </error-page>
</web-app>

  
 
 
 

 

 
 

  到此，springmvc + mybatis + maven 项目配置完毕，下面创建controller和service层，添加一条数据到lgb_bigdata_user表测试项目。
 
 
 

  
 
 
 
 

  九，测试
 
 
 
 
  
  1. 创建com.lgbproject.bigdata.user.controller包，UserController.java文件
     
    package com.lgbproject.bigdata.user.controller;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import com.lgbproject.bigdata.user.model.LgbBigdataUserEntity;
import com.lgbproject.bigdata.user.service.UserService;

@Controller
public class UserController {
	
	@Autowired
	private UserService userService;
	
	@RequestMapping("user.html")
	public String user(ModelMap model, HttpServletRequest request) {
		LgbBigdataUserEntity record = new LgbBigdataUserEntity("xiaoming", "123456", "xiaoming@163.com", new Date(), new Date(), true);
		int result = userService.insertData(record);
		String id = "";
		
		model.addAttribute("id", String.valueOf(result));
		return "user/user";
	}
	
}


     
     
  2. 创建WebContent/WEB-INF/views/user/目录，user.jsp文件
     
    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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>User</title>
</head>
<body>
<h1>Hello User Page</h1>
<br>
${id }
</body>
</html>

     
     
  3. 创建com.lgbproject.bigdata.user.service包，UserService.java文件
     
    package com.lgbproject.bigdata.user.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.lgbproject.bigdata.user.dao.LgbBigdataUserEntityMapper;
import com.lgbproject.bigdata.user.model.LgbBigdataUserEntity;

@Service
public class UserService {
	
	@Autowired
	private LgbBigdataUserEntityMapper lgbBigdataUserEntityMapper;
	
	
	public int insertData(LgbBigdataUserEntity record) {
		return lgbBigdataUserEntityMapper.insert(record);
	}

}
