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：

-- ----------------------------
-- 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;
