最近比较闲,复习搭建一下项目,这次主要使用Spring+SpringMVC+Mybatis。项目持久层使用Mybatis3,控制层使用SpringMVC4.1,使用Spring4.1管理控制器,数据库连接池使用druid数据源,该项数据库暂使用MySQL。
数据表非常的简单(不是重点),如下:
创建maven项目,详细见上一篇maven创建(http://blog.csdn.net/fengshizty/article/details/43019561),创建Maven Project时,将Filter选择为org.apache.maven.archetypes。填写完相关项目坐标信息后项目结构如下:
注:若无src/main/java,src/test/java,src/test/resources时,创建这个几个Source Folder。
这儿将全部使用的Maven依赖贴出了,对应什么作用上面都有解释,如下:

自动生成表的Model,Mapping,Dao文件,先关使用见文章 http://blog.csdn.net/fengshizty/article/details/43086833
并将其导入到项目的src/main/java包中。
其中生成的Model中UserInfo如下:
UserInfo.java(其中List
package org.andy.shop.model;
import java.util.List;
public class UserInfo {
private Integer id;
private String uname;
private Integer unumber;
private List courseInfos;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname == null ? null : uname.trim();
}
public Integer getUnumber() {
return unumber;
}
public void setUnumber(Integer unumber) {
this.unumber = unumber;
}
public List getCourseInfos() {
return courseInfos;
}
}
package org.andy.shop.dao;
import java.util.List;
import org.andy.shop.model.UserInfo;
public interface UserInfoMapper {
int deleteByPrimaryKey(Integer id);
int insert(UserInfo record);
int insertSelective(UserInfo record);
UserInfo selectByPrimaryKey(Integer id);
int updateByPrimaryKeySelective(UserInfo record);
int updateByPrimaryKey(UserInfo record);
List selectAll();
}
id, uname, unumber
delete from
user_info
where id = #{id,jdbcType=INTEGER}
insert into user_info (id,
uname, unumber
)
values (#{id,jdbcType=INTEGER},
#{uname,jdbcType=VARCHAR},
#{unumber,jdbcType=INTEGER}
)
insert into user_info
id,
uname,
unumber,
#{id,jdbcType=INTEGER},
#{uname,jdbcType=VARCHAR},
#{unumber,jdbcType=INTEGER},
update user_info
uname = #{uname,jdbcType=VARCHAR},
unumber = #{unumber,jdbcType=INTEGER},
where id = #{id,jdbcType=INTEGER}
update user_info
set uname = #{uname,jdbcType=VARCHAR},
unumber =
#{unumber,jdbcType=INTEGER}
where id = #{id,jdbcType=INTEGER}
在src/main/resources创建spring的配置文件,这里创建了spring.xml,信息如下:
配置连接池配置信息在config.properties中,如下:
#mysql version database druid setting
validationQuery=SELECT 1
jdbc.url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=12345
以下是mybatis的配置信息:spring-mybatis.xml(ps:名字可随便起)
在src/main/resources中添加log4j日志配置信息:
log4j.properties
### set log levels ###
log4j.rootLogger = INFO , C , D , E
### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc-mybatis-demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc-mybatis-demo_error.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [sspringmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
在src/main/java中创建相关的org.andy.shop.service包和org.andy.shop.service.Impl包。
UserService接口:
package org.andy.shop.service;
import java.util.List;
import org.andy.shop.model.UserInfo;
/**
* 创建时间:2015-1-27 下午5:15:03
* @author andy
* @version 2.2
*/
public interface UserService {
UserInfo getUserById(int id);
List getUsers();
int insert(UserInfo userInfo);
}
UserServiceImpl实现Service:
package org.andy.shop.service.impl;
import java.util.List;
import org.andy.shop.dao.UserInfoMapper;
import org.andy.shop.model.UserInfo;
import org.andy.shop.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* 创建时间:2015-1-27 下午5:22:59
*
* @author andy
* @version 2.2
*/
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
private UserInfoMapper userInfoMapper;
@Override
public UserInfo getUserById(int id) {
return userInfoMapper.selectByPrimaryKey(id);
}
@Override
public List getUsers() {
return userInfoMapper.selectAll();
}
@Override
public int insert(UserInfo userInfo) {
int result = userInfoMapper.insert(userInfo);
System.out.println(result);
return result;
}
}
在src/test/java中写测试类,检测是否能够读出数据,若能读出则证明Spring+Mybatis整合成功。
TestUserService测试类:
package org.andy.shop.service;
import java.util.List;
import org.andy.shop.model.UserInfo;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.alibaba.fastjson.JSON;
/**
* 创建时间:2015-1-27 下午10:45:38
*
* @author andy
* @version 2.2
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
"classpath:spring-mybatis.xml" })
public class TestUserService {
private static final Logger LOGGER = Logger
.getLogger(TestUserService.class);
@Autowired
private UserService userService;
@Test
public void testQueryById1() {
UserInfo userInfo = userService.getUserById(1);
LOGGER.info(JSON.toJSON(userInfo));
}
@Test
public void testQueryAll() {
List userInfos = userService.getUsers();
LOGGER.info(JSON.toJSON(userInfos));
}
@Test
public void testInsert() {
UserInfo userInfo = new UserInfo();
userInfo.setUname("xiaoming");
userInfo.setUnumber(4);
int result = userService.insert(userInfo);
System.out.println(result);
}
}
SpringMVC的配置信息主要包括控制层Controller的bean管理,视图层和控制层配置等等,下面是spring-mvc.xml信息:
text/html;charset=UTF-8
UTF-8
32505856
4096
web容器配置启动加载的配置文件,设置SpringMVC拦截的请求(此处拦截.htmls结尾的url请求)
springmvc_mybatis_demo
contextConfigLocation
classpath:spring.xml,classpath:spring-mybatis.xml
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding
utf-8
forceEncoding
true
encodingFilter
/*
org.springframework.web.context.ContextLoaderListener
org.springframework.web.util.IntrospectorCleanupListener
spring mvc servlet
rest
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:spring-mvc.xml
1
rest
*.htmls
30
index.jsp
在org.andy.shop.controller创建控制层,如UserController.java
package org.andy.shop.controller;
import java.util.List;
import org.andy.shop.model.UserInfo;
import org.andy.shop.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
/**
* 创建时间:2015-1-28 下午1:17:27
* @author andy
* @version 2.2
*/
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/showInfo/{userId}")
public String showUserInfo(ModelMap modelMap, @PathVariable int userId){
UserInfo userInfo = userService.getUserById(userId);
modelMap.addAttribute("userInfo", userInfo);
return "/user/showInfo";
}
@RequestMapping("/showInfos")
public @ResponseBody Object showUserInfos(){
List userInfos = userService.getUsers();
return userInfos;
}
}
在WEB-INF创建视图总目录views(为了安全起见一般都在WEB-INF下创建),创建/user/showInfo.jsp视图文件。
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
userInfo
姓名: ${userInfo.uname}
到此为demo以及基本创建完成总目录如下:
将项目编译,Maven build...输入clean compile package,部署到Tomcat服务器,启动项目。
测试1:测试第一个url, http://localhost:8080/springmvc_mybatis_demo/user/showInfo/1.htmls
测试2:测试第二个json数据返回的url, http://localhost:8080/springmvc_mybatis_demo/user/showInfos.htmls
ok,数据正常显示,SpringMVC+Mybatis搭建成功。
