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。
1、 数据库表结构以及maven项目结构
数据表非常的简单(不是重点),如下:
创建maven项目创建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。
2、修改pom.xml添加对应的包依赖
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:
pom.xml

3、使用Generator自动生成Mybatis相关表信息
自动生成表的Model,Mapping,Dao文件
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 courseInfos手动添加的)
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;
}
}
Dao包中的UserInfoMapper.java
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();
}
mapping 中的配置文件UserInfoMapper.xml
id, uname, unumber
parameterType="java.lang.Integer">
select
from user_info
where id = #{id,jdbcType=INTEGER}
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}
extends="BaseResultMap">
ofType="org.andy.shop.model.CourseInfo">
select u.id, u.uname,
u.unumber, c.id course_id, c.cname, c.caddress from user_info u left
join course_user_info cu on u.id = cu.uid
left join course_info c on
cu.cid = c.id
4、引入Spring并配置相关属性
在src/main/resources创建spring的配置文件,这里创建了spring.xml,信息如下:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd">
5、引入Mybatis并配置数据连接池等信息
5.1、数据连接池druid配置信息
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
5.2、配置Mybatis相关信息
以下是mybatis的配置信息:spring-mybatis.xml(ps:名字可随便起)
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
">
init-method="init" destroy-method="close">
value="33" />
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
expression="execution(* org.andy.shop.service..*Impl.*(..))" />
advice-ref="transactionAdvice" />
主要配置数据连接池,事务管理, mybatis关联映射等,事务采用aop的声明式事务。
6、引入日志
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
7、创建Service
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;
}
}
8、测试Spring和Mybatis配置
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);
}
}
若是测试成功,那证明已经成功了一半了。
9、引入SpringMVC
9.1 配置SpringMVC配置信息
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:
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
text/html;charset=UTF-8
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
value="org.springframework.web.servlet.view.JstlView" />
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
UTF-8
32505856
4096
自动扫描org.andy.shop.controller报下还有@Controller的控制层,注入为bean。
9.2、Web容器web.xml配置
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)
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
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
9.3、Controller控制层
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;
}
}
9.4、视图层
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}
9.5、项目总目录结构
到此为demo以及基本创建完成总目录如下:
10、项目测试
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
核心技术:Maven,Springmvc mybatis shiro, Druid, Restful, Dubbo, ZooKeeper,Redis,FastDFS,ActiveMQ,Nginx
