Spring+SpringMVC+Mybatis+Oracle+Maven整合開發詳解

先說一下，這個搭建之前用的項目名叫mybatis，但是在做項目（blogs）的時候發現有些地方需要修改，也就是配置的不合理，同時也解決了一些實際上的報錯問題，所以你可能看到的配置文件的包名有的是 cy.** 有的是com.andyc.** 。我都上傳了實際項目中的配置，你只需要根據你自己的項目名稱來修改成一致即可，配置問文件！

一、準備工作：

1、JDK、Eclipse（MyEclipse）、Tomcat、MySql或其他數據庫、Navicat等數據庫管理軟件

2、如果不清楚需要哪些jar包、或者不是用Maven，可下載jar包，下載地址

3、查找jar包版本信息網址推薦：

1)、導jar包推薦網址1：https://mvnrepository.com/artifact/org.springframework
2)、導jar包推薦網址2：https://search.maven.org/

4、下載好mybatis-generator的jar包(版本可自行選擇)，本人使用的是1.3.7版本：mybatis-generator-core-1.3.7.jar

下載地址：https://github.com/mybatis/generator/releases

5、準備好生成語句，jar包版本替換爲自己下載的版本：

java -jar mybatis-generator-core-1.3.7.jar -configfile generator.xml -overwrite

6、新建generator.xml文件，代碼如下，請自行更改。

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

</commentGenerator>

</jdbcConnection>

</javaTypeResolver>

</javaModelGenerator>

</sqlMapGenerator>

</javaClientGenerator>

</context>

</generatorConfiguration>

7、生成generator.xml中配置中所需要的文件

生成的文件如下：

8、Maven加載oracle驅動：ojdbc6.jar

注：使用Oracle數據庫，稍微麻煩點，要用到此步驟，MySQL就不需要此步驟！

1)、確認安裝Oracle JDBC Driver的路徑，如我的是：

D:\app\Administrator\product\11.2.0\dbhome_1\jdbc\lib

2)、運行CMD，切換到該路徑下，執行以下命令：

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=ojdbc6.jar

3)、執行成功如下圖所示：

二、創建Maven工程：Ctrl+N

就這樣，Maven的web項目創建完成，然後處理編碼格式、報錯等一系列問題。

1、處理工程編碼格式：UTF-8

2、解決cannot change version of project facet Dynamic Web Module to 3.0問題？先看報錯，如下圖！

3、解決辦法：

1)、Window -> Show View -> Navigator

2)、在Navigator下打開項目.settings目錄下org.eclipse.wst. common.project.facet.core.xml打開修改如下圖：

2)、再次重複第2步即可

3)、解決STS等編輯器自身原因，不出來的文件夾

4)、修改編譯版本

5)、如果你的編輯工具沒有集成Tomcat，因此jsp文件就會有紅叉，添加你的tomcat即可，如下圖：

6)、當上面的步驟都處理了，你會發現項目文件夾上依舊有紅叉，解決辦法如下：

輸入Problems

就這樣，雖然過程很曲折，膽Maven工程還是創建好了！

7)、展示最後Maven工程結構圖

三、引入spring和mybatis需要的jar包

1、引入jar包時，不知道名稱及版本，可使用以下地址查詢

查看jar包版本信息網址：https://search.maven.org/

1)、首先導入spring的包，在框中spring-core

2)、導入mybatis的包，輸入mybatis

3)、導入mybatis-spring整合包：如mybatis-spring

4)、spring 注入Bean依賴包，此包用於@Autowired，輸入：

spring-beans

5)、由於mybatis是操作數據庫的，所以需要加載驅動包

(1)、MySQL驅動包，輸入mysql-connector-java

(2)、Qracle驅動包，輸入com.oracle，這個找不到11.2的版本

6)、junit測試包，輸入junit

7)、引入druid數據源jar包

8)、導入spring-context的jar包，因爲要使用@Service

9)、除上述jar包外，還需要如下jar包，導入方式同上：

spring-tx、spring-jdbc、servlet-api、log4j、fastjson、spring-test、aspectjweaver、commons-fileupload、

jackson-mapper-asl、spring-webmvc、jstl

最後附上所需的基本jar包圖：

10)、pom.xml代碼：

四、將使用mybatis的gengerator工具生成的包整合到Maven項目中

1、將生成文件複製到src/main/java文件夾下，修改添加測試代碼及結構圖如下：

測試成功了，控制檯也展示了我查詢的數據！這說明Spring+Mybatis整合成功了，接下來就整合SpringMVC了！

2、編譯Maven項目：maven install

看到以下結果，就說明編譯也成功了！

3、配置文件：

1)、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://java.sun.com/xml/ns/javaee"

   <servlet>
       <servlet-name>springMvc</servlet-name>

   </welcome-file-list>

   
   <session-config>
       <session-timeout>60</session-timeout>
   </session-config>

</web-app>

4、發佈項目到Tomcat服務器

5、寫好service、controller，並測試

6、輸入http://localhost:8080/currency/usersController/

userInfo.do?id=1 進行測試

說明spring+springMVC+mybatis+maven整合成功了，下面就附上代碼。

7、附上service、controller、test代碼

A、IusersService.java接口代碼

package cy.service;

import cy.model.Users;

/**

* @author Administrator

* @描述用戶Service接口

public interface IUsersService {

/**

* 根據id查詢用戶信息

* @param id

* @return

public Users getUsersById(Integer id);

/**

* 插入用戶信息

* @param users

* @return

public int insertData(Users users);

}

B、UsersServiceImpl.java代碼

package cy.service;

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

import org.springframework.stereotype.Service;

import cy.dao.UsersMapper;

import cy.model.Users;

/**

* @author Administrator

* @描述用戶Service接口實現類

@Service("UsersService") //在spring.xml文件中配置自動掃描service、即啓動時自動注入到spring.xml中

public class UsersServiceImpl implements IUsersService {

private UsersMapper usersMapper;

public UsersMapper getUsersMapper() {

return usersMapper;

}

/**

* 將UsersMapper注入到Service中

* @param usersMapper

* 自動注入

@Autowired

public void setUsersMapper(UsersMapper usersMapper) {

this.usersMapper = usersMapper;

}

/**

C、UserTest.java代碼

package test;

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 cy.model.Users;

import cy.service.IUsersService;

/**

* @描述測試方法3:spring + junit

* @author [email protected]

* 需要導jar包：spring-test

* 注入Service

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {"classpath:spring.xml", "classpath:spring-mybatis.xml"})

public class UserTest {

// 注入Service

private IUsersService service;

public IUsersService getService() {

return service;

}

@Autowired

public void setService(IUsersService service) {

this.service = service;

}

@Test

public void test01() {

Users users = service.getUsersById(1);

System.out.println(users);

System.out.println(users.getUsername());

System.out.println(users.getTelphone());

}

D、UsersController.java代碼

package cy.controller;

import javax.servlet.http.HttpServletRequest;

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

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import cy.model.Users;

import cy.service.IUsersService;

/**

* @author Administrator

* @描述用戶控制器

@Controller // 註解到spring-mvc.xml中，才能自動掃描

@RequestMapping("/usersController") // 訪問路徑(控制器)

public class UsersController {

private IUsersService iUsersService;

public IUsersService getiUsersService() {

return iUsersService;

}

/**

* 自動注入Service

* @param iUsersService

@Autowired

public void setiUsersService(IUsersService iUsersService) {

this.iUsersService = iUsersService;

}

/**

* 根據id查詢用戶詳細信息

* @param id

* @param request

* @return

* 訪問路徑：http://localhost:8080/currency/usersController/userInfo.do?id=1

* @PathVariable - REST風格的URI

* 加上@PathVariable，代表id爲變量

* 訪問路徑1：http://localhost:8080/currency/usersController/userInfo/1.do

* 訪問路徑2：http://localhost:8080/currency/usersController/1/userInfo.do

@RequestMapping("/{id}/userInfo")

// @RequestMapping("/userInfo/{id}") // 訪問userInfo()方法

public String userInfo(@PathVariable Integer id, HttpServletRequest request){

// 根據條件查詢用戶

Users users = iUsersService.getUsersById(id);

// 將查詢信息保存到HttpServletRequest中

request.setAttribute("user", users);

return "admin/userInfo"; // 返回到userInfo.jsp頁面

}

8、userInfo.jsp代碼

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

<!DOCTYPE html >

<html>

<head>

<title>測試springMVC</title>

</head>

<body>

<h1>${user.username}</h1><br>

<h1>${user.telphone}</h1><br>

<h1>我是admin下的userInfo.jsp文件</h1>

</body>

</html>
