Maven搭建SpringMVC+Mybatis项目详解【转】

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
