搭建基于SpringMVC+MyBatis+Maven的web项目

一 开发前准备

1.1 开发环境

Jdk1.6

MyEclipse 10

Tomcat7

MySQL5

1.2 创建表

CREATE TABLE `user` (  

  `ID` int(11) NOT NULL AUTO_INCREMENT,  

  `NAME` char(30) NOT NULL,  

  `PASSWORD` char(30) NOT NULL,  

  PRIMARY KEY (`ID`),  

  KEY `IDX_NAME` (`NAME`)  

) ENGINE=InnoDB DEFAULT CHARSET=utf8

1.3 插入测试数据

INSERT INTO user (ID, NAME, PASSWORD) VALUES (1, 'admin', '123456');  

INSERT INTO user (ID, NAME, PASSWORD) VALUES (2, '张三', '88888');  

INSERT INTO user (ID, NAME, PASSWORD) VALUES (3, '李四', '[email protected]');  

二 创建项目

File->New->Other

 

 

 

 

 

 

 

添加文件夹

src/main/java

src/main/resources

src/test/java

src/test/resources

 

 

 

检查以下3处的jdk版本，保持一致

 

 

 

 

三 配置POM文件

<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">

六 测试

整个项目文件结构如下

 

 

打开浏览器访问http://localhost:8080/test/

访问结果
