本篇文章主要介紹了手把手Maven搭建SpringMVC+Spring+MyBatis框架(超級(jí)詳細(xì)版),具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

SSM（Spring+SpringMVC+Mybatis），目前較為主流的企業(yè)級(jí)架構(gòu)方案。標(biāo)準(zhǔn)的MVC設(shè)計(jì)模式，將整個(gè)系統(tǒng)劃分為顯示層、Controller層、Service層、Dao層四層，使用SpringMVC負(fù)責(zé)請求的轉(zhuǎn)發(fā)和視圖管理，Spring實(shí)現(xiàn)業(yè)務(wù)對象管理, MyBatis作為數(shù)據(jù)對象持久化引擎。

一. 框架詳情

Spring是一個(gè)輕量級(jí)的Java開發(fā)框架，它是為了解決企業(yè)應(yīng)用開發(fā)的復(fù)雜性而創(chuàng)建的。Spring的用途不僅限于服務(wù)器端的開發(fā)。從簡單性、可測試性和松耦合的角度而言，任何Java應(yīng)用都可以從Spring中受益。簡單來說，Spring是一個(gè)輕量級(jí)的控制反轉(zhuǎn)（IoC）和面向切面（AOP）的容器框架

SpringMVC屬于SpringFrameWork的后續(xù)產(chǎn)品，分離了控制器、模型對象、分派器以及處理程序?qū)ο蟮慕巧?，這種分離讓它們更容易進(jìn)行定制

MyBatis是一個(gè)基于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）它消除了幾乎所有的JDBC代碼和參數(shù)的手工設(shè)置以及結(jié)果集的檢索。MyBatis 使用簡單的 XML或注解用于配置和原始映射，將接口和 Java映射成數(shù)據(jù)庫中的記錄

二. 創(chuàng)建Maven項(xiàng)目

1、Eclipse中用Maven創(chuàng)建項(xiàng)目

2、按默認(rèn)Next

3、找到maven-archetype-webapp后，點(diǎn)擊next

4、填寫相應(yīng)的信息，GroupID是項(xiàng)目組織唯一的標(biāo)識(shí)符，實(shí)際對應(yīng)JAVA的包的結(jié)構(gòu)。ArtifactID就是項(xiàng)目的唯一的標(biāo)識(shí)符，實(shí)際對應(yīng)項(xiàng)目的名稱，就是項(xiàng)目根目錄的名稱。Package填了默認(rèn)給你建一個(gè)包，不寫也可以。

5、剛建好的目錄如下

6、Maven規(guī)定必須添加以下Source Folder：

src/main/resources
src/main/java
src/test/resources
src/test/java

在這步之前最好先項(xiàng)目上右鍵選擇properties，然后點(diǎn)擊java build path，在Librarys下，編輯JRE System Library，選擇workspace default jre。

7、分別修改輸出路徑為，對應(yīng)關(guān)系如下：

8、將項(xiàng)目轉(zhuǎn)換成Dynamic Web Project，在項(xiàng)目上右鍵Properties，在左側(cè)選擇 Project Facets。

9、設(shè)置部署時(shí)的文件發(fā)布路徑，刪除test的兩項(xiàng)，因?yàn)閠est是測試使用，并不需要部署。

設(shè)置將Maven的jar包發(fā)布到lib下。Add -> Java Build Path Entries -> Maven Dependencies -> Finish

三. Maven引入需要的JAR包

為了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 編寫數(shù)據(jù)訪問對象 (DAO)的代碼,MyBatis-Spring 提供了一個(gè)動(dòng)態(tài)代理的實(shí)現(xiàn):MapperFactoryBean。這個(gè)類可以讓你直接注入數(shù)據(jù)映射器接口到你的 service 層 bean 中。當(dāng)使用映射器時(shí),你僅僅如調(diào) 用你的 DAO 一樣調(diào)用它們就可以了,但是你不需要編寫任何 DAO 實(shí)現(xiàn)的代碼,因?yàn)?MyBatis-Spring 將會(huì)為你創(chuàng)建代理。

五. 利用MyBatis Generator自動(dòng)創(chuàng)建實(shí)體類、映射文件以及DAO接口

MyBatis屬于一種半自動(dòng)的ORM框架，所以主要的工作就是配置Mapping映射文件，但是由于手寫映射文件很容易出錯(cuò)，所以可利用MyBatis生成器自動(dòng)生成實(shí)體類、DAO接口和Mapping映射文件。這樣可以省去很多的功夫，將生成的代碼copy到項(xiàng)目工程中即可。

生成代碼需要的文件和jar并建立如下目錄結(jié)構(gòu)：

在generatorl.xml中配置相關(guān)的數(shù)據(jù)庫連接，已經(jīng)數(shù)據(jù)庫表：

    </sqlMapGenerator> 
    <!-- 生成DAO的包名和位置 --> 
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.yingjun.test.dao"  
       targetProject="src"> 
       <property name="enableSubPackages" value="true" /> 
    </javaClientGenerator> 
    <!-- 要生成的表 tableName是數(shù)據(jù)庫中的表名或視圖名 domainObjectName是實(shí)體類名 --> 
    <table tableName="other_list" domainObjectName="OtherList" 
      enableCountByExample="fasle" enableUpdateByExample="false" 
      enableDeleteByExample="false" enableSelectByExample="false" 
      selectByExampleQueryId="false" > 
    </table> 
  </context> 
</generatorConfiguration>

打開CMD窗口進(jìn)入該目錄結(jié)構(gòu)，輸入命令行：

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

運(yùn)行完成后會(huì)生成相應(yīng)的dao mapper 和model，是不是很爽。

六. 建立Service層以及conrorller層

package com.yingjun.test.service; 
public interface OtherServiceI {    
  public String getOterList(); 
 
}

package com.yingjun.test.service; 
import java.util.ArrayList; 
import java.util.Arrays; 
import java.util.HashSet; 
import java.util.List; 
import java.util.Map; 
import java.util.Set;  
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service;  
import com.alibaba.fastjson.JSON; 
import com.alibaba.fastjson.serializer.SerializerFeature; 
import com.yingjun.test.dao.OtherListMapper; 
import com.yingjun.test.model.OtherList; 
import com.yingjun.test.model.OtherListDomain; 
@Service 
public class OtherServiceImpl implements OtherServiceI {    
  @Autowired 
  private OtherListMapper otherListMapper; 
  @Override 
  public String getOterList() { 
    Set<String> set=new HashSet<String>(); 
    List<OtherList> list=otherListMapper.selectAll(); 
    List<OtherListDomain> jsonList=new ArrayList<OtherListDomain>(); 
    for(OtherList other:list){ 
      String title=other.getTitle(); 
      if(set.contains(title)){ 
        continue; 
      }else{ 
        List<OtherList> t_list=new ArrayList<OtherList>(); 
        for(OtherList data:list){ 
          if(title.equals(data.getTitle())){ 
            t_list.add(data); 
          } 
        } 
        OtherListDomain domain=new OtherListDomain(); 
        domain.setTitle(title); 
        domain.setItems(t_list); 
        jsonList.add(domain); 
        set.add(other.getTitle()); 
      } 
    } 
    return JSON.toJSONString(jsonList, SerializerFeature.WriteMapNullValue); 
  } 
 
}

package com.yingjun.test.controller; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.ResponseBody;  
import com.alibaba.fastjson.JSON; 
import com.yingjun.test.service.OtherServiceI; 
import com.yingjun.test.service.StockStatusServiceI; 
@Controller 
@RequestMapping(value = "/") 
public class TSSController { 
   
  @Autowired 
  private OtherServiceI otherService; 
   
  @RequestMapping(value="/getOtherList",produces="text/html;charset=UTF-8" )  
  @ResponseBody 
  private String getOtherList(){ 
    String json=otherService.getOterList(); 
    return json; 
  } 
}

七. 建立測試類

import java.util.List; 
import org.apache.log4j.LogManager; 
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; 
@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations = {"classpath:spring.xml"}) 
public class TestMybatis { 
 
  @Autowired 
  private OtherServiceI service; 
 
  @Test 
  public void test() { 
      String list=service.getOterList(); 
      logger.info(list); 
  } 
   
}

八. 通過瀏覽器進(jìn)行驗(yàn)證

http://localhost:8080/TzyjStateService/getOtherList

至此，測試成功，SSM三大框架的整合就完成了，有什么其他需求可以在此基礎(chǔ)繼續(xù)添

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
