Mybatis+maven自动构建dao、mapper、model

1.Pom.xml文件配置：

代码：

<plugins>

            <!-- Mybatis generator代码生成插件 配置 -->

            <plugin>

                <groupId>org.mybatis.generator</groupId>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <version>${plugin.mybatis.generator}</version>

                <configuration>

                    <configurationFile>${mybatis.generator.generatorConfig.xml}</configurationFile>

                    <overwrite>true</overwrite>

                    <verbose>true</verbose>

                </configuration>

            </plugin>

 

2.在resource目录下创建generatorConfig.properties和generatorConfig.xml两个文件。

 

2.1 .generatorConfig.properties文件配置

# 数据库驱动jar 路径

drive.class.path=C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.30\mysql-connector-java-5.1.30.jar

# 数据库连接参数

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8

jdbc.username=simple

jdbc.password=1234

# 包路径配置 

根据项目的包路径设置成自己的路径

model.package=com.ln.web.model   

dao.package=com.ln.web.dao

xml.mapper.package=com.ln.web.mapper

target.project=src/main/java

2.2.generatorConfig.xml文件配置

<?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">

<!-- 配置Run As Maven build : Goals 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true -->

<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->

<generatorConfiguration>

    <!-- 配置文件路径 -->

    <properties url="${mybatis.generator.generatorConfig.properties}"/>

    <!--数据库驱动包路径 -->

    <classPathEntry location="${drive.class.path}"/>

    <context id="DB2Tables" targetRuntime="MyBatis3">

        <!--关闭注释 -->

        <commentGenerator>

            <property name="suppressAllComments" value="true"/>

        </commentGenerator>

        <!--数据库连接信息 -->

        <jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}"

                        password="${jdbc.password}">

        </jdbcConnection>

        <!--生成的model 包路径 -->

        <javaModelGenerator targetPackage="${model.package}" targetProject="${target.project}">

            <property name="enableSubPackages" value="ture"/>

            <property name="trimStrings" value="true"/>

        </javaModelGenerator>

        <!--生成xml mapper文件 路径 -->

        <sqlMapGenerator targetPackage="${xml.mapper.package}" targetProject="${target.project}">

            <property name="enableSubPackages" value="ture"/>

        </sqlMapGenerator>

        <!-- 生成的Dao接口 的包路径 -->

        <javaClientGenerator type="XMLMAPPER" targetPackage="${dao.package}" targetProject="${target.project}">

            <property name="enableSubPackages" value="ture"/>

        </javaClientGenerator>

        <!--对应数据库表名 -->

        <table tableName="user_table"></table> 

    </context>

</generatorConfiguration>

3.运行

项目右键-->run as-->maven build
