手把手Maven搭建SpringMVC+Spring+MyBatis框架(超級詳細版)html
SSM(Spring+SpringMVC+Mybatis),目前較爲主流的企業級架構方案。標準的MVC設計模式,將整個系統劃分爲顯示層、Controller層、Service層、Dao層四層,使用SpringMVC負責請求的轉發和視圖管理,Spring實現業務對象管理, MyBatis做爲數據對象持久化引擎。java
一. 框架詳情mysql
Spring是一個輕量級的Java開發框架,它是爲了解決企業應用開發的複雜性而建立的。Spring的用途不只限於服務器端的開發。從簡單性、可測試性和鬆耦合的角度而言,任何Java應用均可以從Spring中受益。 簡單來講,Spring是一個輕量級的控制反轉(IoC)和麪向切面(AOP)的容器框架。web
SpringMVC屬於SpringFrameWork的後續產品,分離了控制器、模型對象、分派器以及處理程序對象的角色,這種分離讓它們更容易進行定製。spring
MyBatis是一個基於Java的持久層框架。MyBatis提供的持久層框架包括SQL Maps和Data Access Objects(DAO)它消除了幾乎全部的JDBC代碼和參數的手工設置以及結果集的檢索。MyBatis 使用簡單的 XML或註解用於配置和原始映射,將接口和 Java映射成數據庫中的記錄。sql
二. 建立Maven項目數據庫
Eclipse中用Maven建立項目apache
按默認Nextjson
找到maven-archetype-webapp後,點擊next設計模式
填寫相應的信息,GroupID是項目組織惟一的標識符,實際對應JAVA的包的結構。ArtifactID就是項目的惟一的標識符,實際對應項目的名稱,就是項目根目錄的名稱。Package填了默認給你建一個包,不寫也能夠。
剛建好的目錄以下
Maven規定必須添加如下Source Folder:
src/main/resources
src/main/java
src/test/resources
src/test/java
在這步以前最好先項目上右鍵選擇properties,而後點擊java build path,在Librarys下,編輯JRE System Library,選擇workspace default jre。
分別修改輸出路徑爲,對應關係以下:
將項目轉換成Dynamic Web Project,在項目上右鍵Properties,在左側選擇 Project Facets。
設置部署時的文件發佈路徑,刪除test的兩項,由於test是測試使用,並不須要部署。
設置將Maven的jar包發佈到lib下。Add -> Java Build Path Entries -> Maven Dependencies -> Finish
三. Maven引入須要的JAR包

爲了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 編寫數據訪問對象 (DAO)的代碼,MyBatis-Spring 提供了一個動態代理的實現:MapperFactoryBean。這個類 可讓你直接注入數據映射器接口到你的 service 層 bean 中。當使用映射器時,你僅僅如調 用你的 DAO 同樣調用它們就能夠了,可是你不須要編寫任何 DAO 實現的代碼,由於 MyBatis-Spring 將會爲你建立代理。

###Console ###
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern = %d %p[%C:%L]- %m%n
### debug ###
log4j.appender.debug = org.apache.log4j.DailyRollingFileAppender
log4j.appender.debug.File = log/debug.log
log4j.appender.debug.Append =true
log4j.appender.debug.Threshold = DEBUG

log4j.appender.debug.layout = org.apache.log4j.PatternLayout

log4j.appender.error.layout = org.apache.log4j.PatternLayout
log4j.appender.error.layout.ConversionPattern =%d %p[%c:%L] - %m%n
五. 利用MyBatis Generator自動建立實體類、映射文件以及DAO接口
MyBatis屬於一種半自動的ORM框架,因此主要的工做就是配置Mapping映射文件,可是因爲手寫映射文件很容易出錯,因此可利用MyBatis生成器自動生成實體類、DAO接口和Mapping映射文件。這樣能夠省去不少的功夫,將生成的代碼copy到項目工程中便可。
生成代碼須要的文件和jar並創建以下目錄結構:
在generatorl.xml中配置相關的數據庫鏈接,已經數據庫表:
Xml代碼
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
connectionURL="jdbc:mysql://192.168.1.194:3306/noc"
userId="root"password="root">
targetProject="src">
targetProject="src">
targetProject="src">
enableCountByExample="fasle"enableUpdateByExample="false"
enableDeleteByExample="false"enableSelectByExample="false"
selectByExampleQueryId="false">
打開CMD窗口 進入該目錄結構,輸入命令行:
java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite
運行完成後會生成相應的dao mapper 和model,是否是很爽。
六. 創建Service層以及conrorller層
Java代碼
packagecom.yingjun.test.service;
publicinterfaceOtherServiceI {
publicString getOterList();
}
Java代碼
packagecom.yingjun.test.service;
importjava.util.ArrayList;
importjava.util.Arrays;
importjava.util.HashSet;
importjava.util.List;
importjava.util.Map;
importjava.util.Set;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.stereotype.Service;
importcom.alibaba.fastjson.JSON;
importcom.alibaba.fastjson.serializer.SerializerFeature;
importcom.yingjun.test.dao.OtherListMapper;
importcom.yingjun.test.model.OtherList;
importcom.yingjun.test.model.OtherListDomain;
@Service
publicclassOtherServiceImplimplementsOtherServiceI {
@Autowired
privateOtherListMapper otherListMapper;
@Override
publicString getOterList() {
Set set=newHashSet();
List list=otherListMapper.selectAll();
List jsonList=newArrayList();
for(OtherList other:list){
String title=other.getTitle();
if(set.contains(title)){
continue;
}else{
List t_list=newArrayList();
for(OtherList data:list){
if(title.equals(data.getTitle())){
t_list.add(data);
}
}
OtherListDomain domain=newOtherListDomain();
domain.setTitle(title);
domain.setItems(t_list);
jsonList.add(domain);
set.add(other.getTitle());
}
}
returnJSON.toJSONString(jsonList, SerializerFeature.WriteMapNullValue);
}
}
Java代碼
packagecom.yingjun.test.controller;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.stereotype.Controller;
importorg.springframework.web.bind.annotation.RequestMapping;
importorg.springframework.web.bind.annotation.ResponseBody;
importcom.alibaba.fastjson.JSON;
importcom.yingjun.test.service.OtherServiceI;
importcom.yingjun.test.service.StockStatusServiceI;
@Controller
@RequestMapping(value ="/")
publicclassTSSController {
@Autowired
privateOtherServiceI otherService;
@RequestMapping(value="/getOtherList",produces="text/html;charset=UTF-8")
@ResponseBody
privateString getOtherList(){
String json=otherService.getOterList();
returnjson;
}
}
七. 創建測試類
Java代碼
importjava.util.List;
importorg.apache.log4j.LogManager;
importorg.apache.log4j.Logger;
importorg.junit.Test;
importorg.junit.runner.RunWith;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.test.context.ContextConfiguration;
importorg.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring.xml"})
publicclassTestMybatis {
@Autowired
privateOtherServiceI service;
@Test
publicvoidtest() {
String list=service.getOterList();
logger.info(list);
}
}
