最近看見網(wǎng)上整理的Spring+SpringMVC+MyBatis+Maven太low,正好今天有時(shí)間，于是整理了下守呜，那么開始吧！

1、使用的工具

• STS下載地址 http://www.springsource.org/downloads/sts-ggts
• Tomcat
• JDK
• Mybatis generator

• 若使用Eclipse開發(fā)(需要配置Maven,Maven配置好后原杂，在命令行下輸入mvn -v,顯示下圖代表配置成功)

  
  

2、Generator的結(jié)構(gòu)

• 首先得有數(shù)據(jù)庫(kù)表
• src文件夾為生成模型的位置(dao,mapping,model)

• generator.xml配置

  
  
• mybatis-generator-core-1.3.2.jar核心包
• 生成語句復(fù)制您机，右鍵在此處打開命令行(注意路徑不能用中文)

• 生成結(jié)果如下圖所示

  
  

3穿肄、打開Eclipse新建Maven項(xiàng)目

• 如圖紅色箭頭所示，選擇默認(rèn)的空間际看，next

• 最后Finish

• 最后生成項(xiàng)目結(jié)構(gòu)如下圖所示

• 項(xiàng)目建立后被碗，首先我會(huì)把編碼改成utf-8,省的以后有麻煩。
• 你會(huì)發(fā)現(xiàn)項(xiàng)目目錄沒有顯示出來仿村，那么我們選擇屬性如圖

• 這時(shí)你會(huì)發(fā)現(xiàn)目錄還是沒有變化，那么接下來我們?cè)谡{(diào)試兴喂，默認(rèn)是J2SE-1.5

• 那么我們?cè)诰庉嬛付ㄒ幌滤遥鐖D

• 這時(shí)在回過頭來看項(xiàng)目目錄，以完整衣迷。

4畏鼓、項(xiàng)目建立完畢，引入Spring和MyBatis需要的jar包

• 打開pom.xml

• 如果引入的時(shí)候壶谒，記不住groupId和版本號(hào)云矫，其實(shí)在Eclipse里面有一個(gè)如圖所示，當(dāng)然這種方法不好(請(qǐng)看下一種)

• 那么我們選擇手寫汗菜，打開瀏覽器輸入http://search.maven.org/
• 記住spring核心包spring-core
• mybatis
• mybatis-spring
• mysql-connector-java
• junit
• 數(shù)據(jù)源druid
• org.aspectj
• 記住后面還有jar包需要加入

pom.xml代碼

6菌瘪、這樣我們已經(jīng)將Spring和mybatis完全整合了腮敌，接下來上代碼

• 寫接口，查詢一個(gè)資產(chǎn)俏扩，肯定要返回一個(gè)Asset_Check

package dc_zaichi.service;

import dc_zaichi.model.Asset_Check;


public interface AssetCheckService {
    public   Asset_Check  getAssetCheckById(String id); 
    

}

• 接下來寫實(shí)現(xiàn)類

package dc_zaichi.service.Impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import dc_zaichi.dao.Asset_CheckMapper;
import dc_zaichi.model.Asset_Check;
import dc_zaichi.service.AssetCheckService;
//AssetCheckServiceImpl把他放到spring上下文環(huán)境中
@Service("AssetCheckService")
public class AssetCheckServiceImpl implements AssetCheckService{
    
    //AssetCheckServiceImpl處理業(yè)務(wù)邏輯后糜工，業(yè)務(wù)邏輯調(diào)用數(shù)據(jù)庫(kù)，就是dao,也就是mappper,要使用這個(gè)mapper录淡，一定要通過spring注入捌木，首先要有g(shù)et和set方法，那么如何將Asset_CheckMapper 注入到services里面呢赁咙？在set方法上加@Autowired注解

//當(dāng)然了钮莲，這個(gè)service還是一個(gè)普通的類免钻，因?yàn)闆]有放到spring上下文環(huán)境當(dāng)中，自動(dòng)掃描包后需要一個(gè)serviced的注解告訴掃描的那個(gè)地方崔拥，這個(gè)類是一個(gè)bean极舔。這樣spring上下文在啟動(dòng)的時(shí)候，就能加入到spring環(huán)境當(dāng)中了 
    
    private Asset_CheckMapper  asset_CheckMapper;

    public Asset_CheckMapper getAsset_CheckMapper() {
        return asset_CheckMapper;
    }
    //
    @Autowired
    public void setAsset_CheckMapper(Asset_CheckMapper asset_CheckMapper) {
        this.asset_CheckMapper = asset_CheckMapper;
    }
   public Asset_Check getAssetCheckById(String id) {
        // TODO Auto-generated method stub
        return asset_CheckMapper.selectByPrimaryKey(id);
    }

}

7链瓦、測(cè)試拆魏，因?yàn)槭?strong>Maven項(xiàng)目, 在src/test/java目錄下建立包名和測(cè)試類，通過junit測(cè)試

package mybatis.test;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import dc_zaichi.model.Asset_Check;
import dc_zaichi.service.AssetCheckService;

public class TestMyBatis {
    @Test
    public void test1(){
        ApplicationContext ac= 
                new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});
        AssetCheckService  bean = (AssetCheckService) ac.getBean("AssetCheckService");
    //這個(gè)bean就是實(shí)現(xiàn)類中的那個(gè)service注解
        Asset_Check assetCheckById = bean.getAssetCheckById("1");
        System.out.println(assetCheckById.getAcName());
        
    }
 
}

• 打印如下

8慈俯、設(shè)想下渤刃，測(cè)試類中有一個(gè)測(cè)試方法我們可以這樣寫， 如果有100個(gè)測(cè)試方法贴膘，那么這個(gè)速度難以忍受卖子，因?yàn)閟pring在初始化的時(shí)候，即耗資源又耗時(shí)間刑峡。那么我們可以這樣寫

package mybatis.test;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import dc_zaichi.model.Asset_Check;
import dc_zaichi.service.AssetCheckService;

public class TestMyBatis {
    private ApplicationContext ac;
    AssetCheckService  bean;
    
    @Before
    public void before(){
         
        ac=new ClassPathXmlApplicationContext(new String[]{"spring.xml","spring-mybatis.xml"});
        bean = (AssetCheckService) ac.getBean("AssetCheckService");
    }
    
    
    @Test
    public void test1(){
        Asset_Check assetCheckById = bean.getAssetCheckById("1");
        System.out.println(assetCheckById.getAcName());
        
    }
 
}
  

@Before的作用：在當(dāng)前這個(gè)類所有測(cè)試方法之前去執(zhí)行的這么一個(gè)方法洋闽。將所有初始化的東西放到這個(gè)放到這個(gè)方法之內(nèi)。那么只會(huì)執(zhí)行一次

到此突梦，說明spring和mybatis整合成功

接下里再看一種測(cè)試方法：添加spring-test的jar包依賴

package mybatis.test;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import dc_zaichi.model.Asset_Check;
import dc_zaichi.service.AssetCheckService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
        "classpath:spring-mybatis.xml" })
public class TestMyBatis {
    private AssetCheckService assetCheckService;

    public AssetCheckService getAssetCheckService() {
        return assetCheckService;
    }

    @Autowired
    public void setAssetCheckService(AssetCheckService assetCheckService) {
        this.assetCheckService = assetCheckService;
    }

    // private ApplicationContext ac;
    // AssetCheckService bean;

    // @Before
    // public void before(){
    //
    // ac=new ClassPathXmlApplicationContext(new
    // String[]{"spring.xml","spring-mybatis.xml"});
    // bean = (AssetCheckService) ac.getBean("AssetCheckService");
    // }
    //

    @Test
    public void test1() {
        Asset_Check assetCheckById = assetCheckService.getAssetCheckById("1");
        System.out.println(assetCheckById.getAcName());

    }

}

ok

• 接下來虚汛，我們建立一個(gè)包，和類如下圖

• 建立Controller類如下圖所示

package dc_zaichi.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import dc_zaichi.model.Asset_Check;
import dc_zaichi.service.AssetCheckService;

@Controller
// 加入到springmvc的上下文當(dāng)中
@RequestMapping("/assetCheckController")
// 這個(gè)東西就是訪問地址的一個(gè)配置
public class AssetCheckController {

    // 比如說執(zhí)行 http://127.0.0.1:8080/mybatis/assetCheckController.do 訪問此控制器

    private AssetCheckService assetCheckService;

    public AssetCheckService getAssetCheckService() {
        return assetCheckService;
    }

    @Autowired
    public void setAssetCheckService(AssetCheckService assetCheckService) {
        this.assetCheckService = assetCheckService;
    }

    @RequestMapping("/showAssetCheck")
    public String showAssetCheck(String id, HttpServletRequest request) {

        // http://localhost:8080/mybatis/assetCheckController.do?id=1
        // 后臺(tái)接的時(shí)候畜吊，接到這個(gè)id,并且去數(shù)據(jù)庫(kù)查找這個(gè)資產(chǎn)泽疆，也就是AssetCheckController訪問數(shù)據(jù)庫(kù)，不能直接
        // 訪問玲献，得通過業(yè)務(wù)邏輯service
        // 訪問此控制器里的一個(gè)方法
        // http://127.0.0.1:8080/mybatis/assetCheckController.showAssetCheck.do

        Asset_Check assetCheckById = assetCheckService.getAssetCheckById(id);
        System.out.println(assetCheckById.getAcName());
        // 把a(bǔ)ssetCheckById存到Request中
        request.setAttribute("Asset_Check", assetCheckById);
        return "showAssetCheck";// 返回一個(gè)jsp,不用howAssetCheck.jsp,已經(jīng)在spring-mvc中配置好

    }
