由于工作主要是前端开发,做后端的项目比较少,最近自己做个项目,发觉好多的都忘了,这里写篇博客整理下maven工程下整合spring+mybatis+freemarker相关内容。

新建个Archetype为maven-archetype-webapp的maven项目(安装maven插件:http://download.eclipse.org/technology/m2e/releases),在pom文件添加相关依赖:

新建source folder:src/main/resource,新建一个mysql的属性文本src/main/resource/prop/mysql.properties:

jdbc.url=jdbc:mysql://localhost:3306/sport
jdbc.username=root

创建mysql示例数据库sport:

-- ----------------------------
--  Table structure for `user_login`
-- ----------------------------
DROP TABLE IF EXISTS `user_login`;
CREATE TABLE `user_login` (
  `user_id` int(11) NOT NULL AUTO_INCREMENT,
  `user_name` varchar(50) NOT NULL,
  `password` varchar(100) NOT NULL,
  `email` varchar(100) NOT NULL,
  PRIMARY KEY (`user_id`,`email`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

-- ----------------------------
--  Records of `user_login`
-- ----------------------------
BEGIN;
INSERT INTO `user_login` VALUES ('1', 'ee', '111111111', 'ddsd@126.com'), ('2', 'ww', '33333', 'ddddasssss@163.com');
COMMIT;
新建实体类UserLoginEntity.java:

package com.sport.entity;

import java.io.Serializable;

public class UserLoginEntity implements Serializable{
	
	private static final long serialVersionUID = 1L;
	private int userId;
	private String userName;
	private String email;
	private String password;
	
	public int getUserId() {
		return userId;
	}
	public void setUserId(int userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public static long getSerialversionuid() {
		return serialVersionUID;
	}
	
	
	
}
新建dao接口IUserLoginDao.java:

package com.sport.dao;

import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.sport.entity.UserLoginEntity;

@Repository
@Transactional
public interface IUserLoginDao {

	public UserLoginEntity getUserLogin(int userId);

}
新建对应的mybatis配置文件com.sport.mapper/UserLoginMapper.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 这里的namespace名字必须为执行该sql的dao地址 -->
<mapper namespace="com.sport.dao.IUserLoginDao">
	
	<resultMap type="UserLoginEntity" id="userLoginResultMap">  
        <id property="userId" column="user_id"/>  
        <result property="password" column="password"/>  
        <result property="userName" column="user_name"/>  
        <result property="email" column="eamil"/>
    </resultMap>
     
	<select id="getUserLogin" parameterType="String" resultType="UserLoginEntity" resultMap="userLoginResultMap">  
        <![CDATA[ 
            select * from user_login where user_id =  #{userId}
        ]]>   
    </select>
    
</mapper>

再新建简单的service接口IUserLoginService.java:

package com.sport.service;

import com.sport.entity.UserLoginEntity;

public interface IUserLoginService {

	public UserLoginEntity checkLogin(int userId);
	
}

UserLoginServiceImpl.java:

package com.sport.service.impl;

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

import com.sport.dao.IUserLoginDao;
import com.sport.entity.UserLoginEntity;
import com.sport.service.IUserLoginService;

@Service("userLoginService")
public class UserLoginServiceImpl implements IUserLoginService {
	
	@Autowired
	private IUserLoginDao userLoginDao;

	public UserLoginEntity checkLogin(int userId) {
		UserLoginEntity userLogin= userLoginDao.getUserLogin(userId);
		return userLogin;
	}
	
	

}

新建controller类UserLogin.java:

package com.sport.web.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.sport.entity.UserLoginEntity;
import com.sport.service.IUserLoginService;


@Controller
@RequestMapping("userLogin")
public class UserLogin {
	
	@Autowired
	private IUserLoginService userLoginService;

	@RequestMapping("test.do")
	public ModelAndView test(){
		ModelAndView m=new ModelAndView(); 
		UserLoginEntity userLoginEntity=userLoginService.checkLogin(1);
		m.addObject("result", userLoginEntity);
		m.setViewName("test");
		return m;
	}
	
}

整合freemarker,新建配置文件src/main/resources/freemarker.properties:

tag_syntax=auto_detect
template_update_delay=2
default_encoding=UTF-8
output_encoding=UTF-8
locale=zh_CN
date_format=yyyy-MM-dd
time_format=HH:mm:ss
datetime_format=yyyy-MM-dd HH:mm:ss

在src/main/resources/dispatcher-servlet.xml中加入freemarker配置:

        <!-- 设置freeMarker的配置文件路径 -->
	<bean id="freemarkerConfiguration"
		class="org.springframework.beans.factory.config.PropertiesFactoryBean">
		<property name="location" value="classpath:prop/freemarker.properties" />
	</bean>

	<bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape" />

	<!-- 配置freeMarker的模板路径 -->
	<bean id="freemarkerConfig"
		class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
		<property name="templateLoaderPath">
			<value>/WEB-INF/views/</value>
		</property>
		<property name="freemarkerVariables">
			<map>
				<entry key="xml_escape" value-ref="fmXmlEscape" />
			</map>
		</property>
	</bean>


	<!-- 配置freeMarker视图解析器 -->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" />
		<property name="contentType" value="text/html; charset=utf-8" />
		<property name="cache" value="true" />
		<property name="prefix" value="" />
		<property name="suffix" value=".ftl" />
		<property name="exposeSpringMacroHelpers" value="true"></property>
		<property name="exposeRequestAttributes" value="true"></property>
	</bean>

新建测试页面src/main/webapp/WEB-INF/views/test.ftl:

<html>  
<head>  
<title>test</title>
</head>
<body>
test:userId:${result.userId};userName:${result.userName};email:${result.email};
</body>
</html>

启动jetty服务器(runjettyrun插件:http://run-jetty-run.googlecode.com/svn/trunk/updatesite),浏览器输入http://localhost:8080/sport-web/userLogin/test.do可以看到如下结果:

test:userId:1;userName:ee;email:ddsd@126.com;

maven学习之maven与eclipse集成

- - ITeye博客
    在上一篇博文中讲到了maven的配置,今天要讲maven与eclipse的集成. 现在在java开发中,eclipse占据了绝大部分的市场份额. 其他的关于NetBeans,IDEA中的关于maven的配置,读者可参阅相关资料. (注:关于IDEA,据说是款非常强大的集成开发环境,但是据说对svn的支持不是很好,道听途说而已).

Maven最佳实践:划分模块

- - 企业架构 - ITeye博客
“分天下为三十六郡,郡置守,尉,监” —— 《史记·秦始皇本纪》. 所有用Maven管理的真实的项目都应该是分模块的,每个模块都对应着一个pom.xml. 它们之间通过继承和聚合(也称作多模块,multi- module)相互关联. 我们明明在开发一个项目,划分模块后,导入Eclipse变成了N个项目,这会带来复杂度,给开发带来 不便.

从Maven仓库中导出jar包

- - 企业架构 - ITeye博客
从Maven仓库中导出jar包:进入工程pom.xml 所在的目录下,. 输入以下命令:mvn dependency:copy-dependencies -DoutputDirectory=lib. 更简单的  mvn dependency:copy-dependencies    会导出到target\dependency 下面.

Maven 3 入门 -- 核心概念

- - 开源软件 - ITeye博客
例如上篇helloworld的pom.xml配置文件中的. 其实就是坐标,那么Maven的坐标元素包括groupId、artifactId、version、packaging、classifier. 当一个项目通过依赖,插件或者父项目引用与另外一个项目关联的时候,Maven通过坐标来精确定位一个项目.

简单的Maven模块结构

- - 研发管理 - ITeye博客
简单的Maven模块结构是这样的:. 上述简单示意图中,有一个父项目(app-parent)聚合很多子项目(app-util, app-dao, app-service, app-web). 每个项目,不管是父子,都含有一个pom.xml文件. 而且要注意的是,小括号中标出了每个项目的打包类型. 父项目是pom,也只能是pom.

maven导出项目依赖的jar包

- - 互联网 - ITeye博客
在进行项目部署时,需要将maven项目所依赖的jar导出到指定目录,本文讲解如何导出项目依赖的jar包. 一、导出到默认目录 targed/dependency .     从Maven项目中导出项目依赖的jar包:进入工程pom.xml 所在的目录下,执行如下命令:.        或在eclipse中,选择项目的pom.xml文件,点击右键菜单中的Run As,见下图红框中,在弹出的Configuration窗口中,输入  dependency:copy-dependencies 后,点击运行.

Maven使用archetype生成项目

- -
Archtype指项目的骨架, Maven中的 maven-archetype-plugin插件使用户可以方便的生成所需的项目骨架.. ###1.命令行调用maven插件. 如果不加任何参数,命令窗口显示的会有上千中项目骨架可够选择,我们可以使用 -DarchetypeCatalog, -Dfilter选择过滤项目骨架,参数赋值的格式跟JAVA设置系统属性一样 -D=.
