Maven搭建SpringMVC+Mybatis專案詳解【轉】

weixin_34087301發表於2016-09-10

最近比較閒,複習搭建一下專案,這次主要使用Spring+SpringMVC+Mybatis。專案持久層使用Mybatis3,控制層使用SpringMVC4.1,使用Spring4.1管理控制器,資料庫連線池使用druid資料來源,該項資料庫暫使用MySQL。

1、 資料庫表結構以及maven專案結構

資料表非常的簡單(不是重點),如下:

2650014-fef0ff88156e9223.png

建立maven專案建立Maven Project時,將Filter選擇為org.apache.maven.archetypes。填寫完相關專案座標資訊後專案結構如下:

2650014-b335096b7c236102.png

注:若無src/main/java,src/test/java,src/test/resources時,建立這個幾個Source Folder。

2、修改pom.xml新增對應的包依賴

這兒將全部使用的Maven依賴貼出了,對應什麼作用上面都有解釋,如下:

pom.xml

3、使用Generator自動生成Mybatis相關表資訊

自動生成表的Model,Mapping,Dao檔案

並將其匯入到專案的src/main/java包中。

其中生成的Model中UserInfo如下:

UserInfo.java(其中List courseInfos手動新增的)

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 中的配置檔案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並配置相關屬性

在src/main/resources建立spring的配置檔案,這裡建立了spring.xml,資訊如下:


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並配置資料連線池等資訊

5.1、資料連線池druid配置資訊

配置連線池配置資訊在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相關資訊

以下是mybatis的配置資訊:spring-mybatis.xml(ps:名字可隨便起)


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" />

主要配置資料連線池,事務管理, mybatis關聯對映等,事務採用aop的宣告式事務。

6、引入日誌

在src/main/resources中新增log4j日誌配置資訊:

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、建立Service

在src/main/java中建立相關的org.andy.shop.service包和org.andy.shop.service.Impl包。

UserService介面:

package org.andy.shop.service;

import java.util.List;

import org.andy.shop.model.UserInfo;

/**

* 建立時間: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實現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;

/**

* 建立時間: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、測試Spring和Mybatis配置

在src/test/java中寫測試類,檢測是否能夠讀出資料,若能讀出則證明Spring+Mybatis整合成功。

TestUserService測試類:

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;

/**

* 建立時間: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);

}

}

若是測試成功,那證明已經成功了一半了。

9、引入SpringMVC

9.1 配置SpringMVC配置資訊

SpringMVC的配置資訊主要包括控制層Controller的bean管理,檢視層和控制層配置等等,下面是spring-mvc.xml資訊:


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

自動掃描org.andy.shop.controller報下還有@Controller的控制層,注入為bean。

9.2、Web容器web.xml配置

web容器配置啟動載入的配置檔案,設定SpringMVC攔截的請求(此處攔截.htmls結尾的url請求)


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控制層

在org.andy.shop.controller建立控制層,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;

/**

* 建立時間: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、檢視層

在WEB-INF建立檢視總目錄views(為了安全起見一般都在WEB-INF下建立),建立/user/showInfo.jsp檢視檔案。

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

userInfo

姓名: ${userInfo.uname}

9.5、專案總目錄結構

到此為demo以及基本建立完成總目錄如下:

2650014-aefd0d3f4581a83f.png

10、專案測試

將專案編譯,Maven build...輸入clean compile package,部署到Tomcat伺服器,啟動專案。

測試1:測試第一個url,  http://localhost:8080/springmvc_mybatis_demo/user/showInfo/1.htmls

2650014-31dfa50eb49b9d01.png

測試2:測試第二個json資料返回的url,  http://localhost:8080/springmvc_mybatis_demo/user/showInfos.htmls

2650014-dd00c480bafb88da.png

核心技術:Maven,Springmvc mybatis shiro, Druid, Restful, Dubbo, ZooKeeper,Redis,FastDFS,ActiveMQ,Nginx
