使用IDEA配置Maven + SpringMVC + Mybatis 【一步一步踩坑詳細配置完成】

本文轉載自查看原文 2018-04-02 14:57 1535 Java

PS:初學，想使用Maven配置一個SpringMVC的開發環境，照着網上的各種圖文解說，配置了好久都沒成功，有些寫的不夠詳細，有些只有寫一半，走了不少彎彎繞繞，踩了不少的坑，此文將正確配置成功的步驟全部記錄下來。

1、環境

IDEA 2017.3
Maven 使用了 IDEA自帶Maven，亦可以不用自帶的（沒什么大區別），不用IDEA自帶的可以先去下載maven安裝並設置。

　　 Maven 安裝配置 http://www.cnblogs.com/yangdaxian/p/8676373.html

JDK 1.8 　　　　JDK需要先下載安裝配置好
Spring
Mybatis
MySQL 5.1.41　　MySQL需要保證可用
Tomcat 8

2、SSM整合

新建數據庫表

CREATE TABLE `user` (
  `id` varchar(10) NOT NULL,
  `name` varchar(20) DEFAULT NULL,
  `sex` varchar(5) DEFAULT NULL,
  `age` varchar(3) DEFAULT NULL,
  `address` varchar(100) DEFAULT NULL,
  `phone` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8；

INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('1', '張三', '男', '18', '共住地球村', '18888888881');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('2', '李四', '男', '16', '共住地球村', '18888888882');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('3', '洪五', '女', '22', '共住地球村', '18888888883');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('4', '馬六', '女', '17', '共住地球村', '18888888884');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('5', '孫七', '女', '23', '共住地球村', '18888888885');
INSERT INTO mytest.`user`(id, name, sex, age, address, phone) VALUES('6', '趙八', '男', '38', '共住地球村', '18888888886');

新建maven項目

選擇好自己的JDK路徑

設置項目的group id， artifactid， version等信息

設置maven倉庫路徑，我這邊偷懶直接使用了idea自帶的

項目名設置，然后Finish

等待后生成結構如下，右下角選擇 Enable Auto-import 自動導入；

如果沒有自動導入這個選項，pom.xml配置完成后可以在右側邊緣找到 Maven Projects 打開后點擊第一個類似刷新的按鈕進行下載

新建結構目錄如下（若想要包分層結構顯示在,上面齒輪那的第二行菜單，【Hide Empty Middle Packages】，將以選中的勾去掉就行）
新建的 java 文件需要對它轉一下， java文件夾上右擊 --> Make Diretorys as --> Sources Root (藍色) /Test Sources Root (綠色)

【pom.xml 配置】

在<build>中添加如下信息

　　　　<!--plugins添加逆向工程插件-->
　　　　<plugins>
　　　　...  默認信息
　　　　<!--mybatis逆向工程插件-->
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>

      </plugin>

      <plugin>

          <!-- 設置JDK版本 -->
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>

    <finalName>springmvc</finalName>

    <!--若不配置，可能會發送打包不全-->
    <resources>
      <resource>
        <!--需要打包的目錄-->
        <directory>src/main/java</directory>
        <!--目錄中的文件類型-->

          <include>**/*.properties</include>
        </includes>
      </resource>
    </resources>

在 <dependencies>之前設置變量參數

  <!-- 設置變量參數 -->
  <properties>
    <!-- 設置項目編碼編碼 -->
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

配置 log4j.properties

在resources下新建，根據實際路徑更改輸出日志路徑（D:/WorkSpace/idea_workSpase/springmvc/src/main/webapp/WEB-INF/log/log.txt）

#日志輸出級別
log4j.rootLogger=debug,stdout,D,E

#設置stdout的日志輸出控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#輸出日志到控制台的方式，默認為System.out
log4j.appender.stdout.Target = System.out
#設置使用靈活布局
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#靈活定義輸出格式
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p]  method:[%c (%rms)] - %m%n

#每天產生一個日志文件
log4j.appender.D=org.apache.log4j.DailyRollingFileAppender
#設置的輸出日志
log4j.appender.D.File=D:/WorkSpace/idea_workSpase/springmvc/src/main/webapp/WEB-INF/log/log.txt
#設置的日志最大限制
log4j.appender.D.MaxFileSize=6000KB
#最多只保存20個備份文件
log4j.appender.D.MaxBackupIndex=20
#輸出INFO級別以上的日志
og4j.appender.D.Threshold=debug
log4j.appender.D.Append = true
log4j.appender.D.ImmediateFlush = true
#log4j.appender.D.DatePattern ='.'yyyy-MM-dd
#設置使用靈活布局
log4j.appender.D.layout=org.apache.log4j.PatternLayout
#靈活定義輸出格式
log4j.appender.D.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p]  method:[%l (%rms)] - %m%n

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =D:/WorkSpace/idea_workSpase/springmvc/src/main/webapp/WEB-INF/log/error/error.txt
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR
#log4j.appender.E.DatePattern = '_'yyyyMMdd'.log'
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss,SSS} -[%p]  method:[%l (%rms)] - %m%n

配置 jdbc.properties

在resources下新建；需要更改本地驅動路徑與數據庫連接信息

jdbc.driverLocation=C:\\Users\\yq\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.41\\mysql-connector-java-5.1.41.jar
jdbc.driverClasss=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.56.107:3306/mytest?useUnicode=true&characterEncoding=UTF-8
#聲明使用username可能會與系統jvm沖突
jdbc.username=demo
jdbc.password=demo

驅動包路徑查看方式：找到對應驅動后右擊 --> copy path

配置generatorConfig.xml

mybatis逆向工程配置文件generatorConfig.xml，此配置文件名稱不要改變

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

在這邊你可能遭遇（沒遇到請跳過）

http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd 識別不到的問題，可進行如下操作，File --> Setting 添加未識別的項

測試逆向生成是否成功

配置完成后，可以測試逆向生成是否配置成功了~

點擊左上角綠色的 + ，設置好 Name(自定義) 與 Command line

選中剛才設置的，點擊執行，如果正確配置了能看到在 dao 與 model中均生成了如下文件，這個User表是在generatorConfig.xml中配置的；如果出現錯誤了，排查下配置文件

測試查詢數據庫是否成功

在test --> dao 目錄下新建一個測試類，測試下現在能否讀取到數據庫內容

package com.yq.dao;

import com.yq.model.User;
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({"classpath:spring-mybatis.xml"})
public class UserQueryTest {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void queryUserName() {
        String id = "1";
        User user = userMapper.selectByPrimaryKey(id);
        System.out.println(user.getName());
    }
}

webapp文件下創建index.jsp文件

Hello World！ 你的配置是正確噠！！！~~~

配置Tomcat

配置完成，啟動看看~~

從數據庫取數據來展示

現在上面已經配置成功了，接下去就要試試從數據庫取數據來展示了
創建UserService

package com.yq.service;

import com.yq.dao.UserMapper;
import com.yq.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;

    public User getUserById(String id){
        return userMapper.selectByPrimaryKey(id);
    }
}

創建UserController

package com.yq.controller;

import com.yq.model.User;
import com.yq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/userInfo")
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/getUser")
    public ModelAndView getUser(String id){
        ModelAndView modelAndView = new ModelAndView();
        User user = userService.getUserById(id);
        modelAndView.addObject("userInfo",user);
        modelAndView.setViewName("userInfo/getUser");
        return modelAndView;
    }
}

創建jsp文件，我們在spring-mvc.xml中配置了目錄

因此我們要在 WEB-INF下新建個jsp文件夾

getUser.jsp

<body>
<p>編號： ${userInfo.id}</p>
<p>姓名：${userInfo.name}</p>
<p>性別：${userInfo.sex}</p>
<p>年齡：${userInfo.age}</p>
<p>地址：${userInfo.address}</p>
<p>電話： ${userInfo.phone}</p>

</body>

</html>

訪問 http://localhost:8080/springmvc/userInfo/getUser?id=2

完成，沒毛病；配置期間如果由於環境問題會出現一些異常錯誤，一般拷貝錯誤度娘下都能解決掉，都不是什么大問題。共勉~
