Java框架搭建-Maven、Mybatis、Spring MVC整合搭建

Java框架搭建-Maven、Mybatis、Spring MVC整合搭建1. 下载eclipse到网站下载 http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/marsr选择自己所要的版本2. 新建Maven项目选择File –> New –> Maven Project可看到下面界面点击Next，可看到下面界面，我们选择maven-archetype-webapp点击Next，可看到。Group Id为包名，Artifact Id为项目名。这里我们输入Group Id=com.cjt, Artifact Id=MyMaven。最后点击Finish成功创建项目 3. 项目运行前准备工作新建项目之后，可以看到错误，这是build path与没有引入javaee包引起的。1）设置build path右键项目 –> Build Path --> Configure Build Path…然后选择Libraries Maven默认是选择一个Library的，这个错误的，我们双击这个来Edit。下面界面我们选择Alternate JRE或者Workspace default JRE。这里我们选择Alternate JRE。2）引入javaee包在pom.xml上引入javaee包<！-- 导入java ee jar 包 --><dependency><groupId>javax</groupId><artifactId>javaee-api</artifactId><version>7.0</version></dependency>4. 项目配置文件设置1）设置pom.xml我们现在设置pom.xml，下载jar包，这个过程可能有点慢Pom.xml:<projectxmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>上面的文件都创建在resources文件夹下 5. 数据库代码自动生成1）新建表首先，我们新建表user_t，字段如下：2）下载包下载包有：mybatis-3.2.6.jar、mybatis-generator-core-1.3.3.jar、mysql-connector-java-5.1.39-bin.jar3）运行-自动生成代码新建一个文件夹，下面包括如下文件generatorConfig.xml是生成代码的xml文件，内容如下：<？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>
<！-- 数据库驱动-->
<classPathEntry location="mysql-connector-java-5.1.39-bin.jar"/>
<contextid="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<propertyname="suppressDate" value="true"/>
<！-- 是否去除自动生成的注释 true：是： false:否-->
<propertyname="suppressAllComments" value="true"/>
</commentGenerator>
<！--数据库链接URL，用户名、密码-->
<jdbcConnectiondriverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="">
</jdbcConnection>
<javaTypeResolver>
<propertyname="forceBigDecimals" value="false"/>
</javaTypeResolver>
<！-- 生成模型的包名和位置-->
<javaModelGeneratortargetPackage="com.cjt.domain" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
<propertyname="trimStrings" value="true"/>
</javaModelGenerator>
<！-- 生成映射文件的包名和位置-->
<sqlMapGeneratortargetPackage="com.cjt.mapping" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
</sqlMapGenerator>
<！-- 生成DAO的包名和位置-->
<javaClientGeneratortype="XMLMAPPER" targetPackage="com.cjt.dao" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
</javaClientGenerator>
<！-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
<tabletableName="user_t" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>然后我们用cmd命令进入到新建的文件夹下面，输入：

java -jar mybatis-generator-core-1.3.3.jar -configfile generatorConfig.xml -overwrite

最后，代码生成了。备注：代码自动生成这里通过命令行的方式，读者也可以通过eclipse的插件方式生成。 6. 代码开始新建包，如下：（箭头的都是上面自动生成的代码）IUserService.javapublic interface IUserService {public User getUserById（int id）;}UserServiceImpl.java@Service
public class UserServiceImpl implements IUserService {

@Autowired
private IUserDao userDao;

public UserServiceImpl（） {
System.out.println（"UserServiceImpl"）;
}

public User getUserById（int id） {
return userDao.selectByPrimaryKey（id）;
}

}UserController.java@Controller
@RequestMapping（"/user"）
public class UserController {

public UserController（） {
System.out.println（"UserController"）;
}

@Resource
private IUserService userService;

@RequestMapping（"/showUser"）
public String toIndex（HttpServletRequest request,Model model） {
System.out.println（"UserController showUser"）;
int id = Integer.parseInt（request.getParameter（"id"））;
User user= userService.getUserById（id）;
model.addAttribute（"user", user）;
return "showUser";
}

}在WEB-INF下新建一个目录jsp，下面新建文件showUser.jspshowUser.jsp<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" import="java.util.*,com.cjt.domain.*"%>
<！DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
