Maven項目中，使用mybatis,根據資料庫自動產生pojo實體類、dao、mapper

標籤：

一、首先，用eclipse建立一個maven項目。

二、其次，在pom.xml檔案下，加入如下外掛程式配置：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.liyi.test</groupId>  <artifactId>hello-mybatis</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>hello-mybatis Maven Webapp</name>  <url>http://maven.apache.org</url>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>  </dependencies>  <build>    <finalName>hello-mybatis</finalName>      <pluginManagement>           <plugins>              <plugin>            <groupId>org.mybatis.generator</groupId>            <artifactId>mybatis-generator-maven-plugin</artifactId>            <version>1.3.2</version>            <configuration>                <configurationFile>src/main/resources/generator.xml</configurationFile>                <verbose>true</verbose>                <overwrite>true</overwrite>             </configuration>             <executions>                <execution>                    <id>Generate MyBatis Artifacts</id>                    <goals>                        <goal>generate</goal>                    </goals>                </execution>             </executions>             <dependencies>                <dependency>                    <groupId>org.mybatis.generator</groupId>                    <artifactId>mybatis-generator-core</artifactId>                    <version>1.3.2</version>                </dependency>             </dependencies>            </plugin>        </plugins>         </pluginManagement>     </build></project>

三、從pom.xml中找到configurationFile標籤，按照標籤上的路徑（src/main/resources/generator.xml）放入以下產生代碼的核心設定檔，generator.xml：

<?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">

四、cmd開啟dos視窗，到項目的根路徑，比如我的

      cd D:\Program Files\eclipseworkspace\cn-chejinbao-ecommerce

       執行mvn mybatis-generator:generate(前提是你的電腦配置了maven的環境變數，可以用mvn命令)

       重新整理項目就有以下效果了。

Maven項目中，使用mybatis,根據資料庫自動產生pojo實體類、dao、mapper
