idea generate persistence mapping 生成dao bean实例

1.新建一个hibernate项目

2.添加一个数据库连接

3，配置数据表和mapping bean映射

生成后的结果：

4 ， hibernate persistence mapping和mybatis-generator 比较各有利弊吧，看个人喜好选择。

2）generator-config.xml文件配置

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

        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

                        password="bwuser">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->

            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="mapper" targetProject="D:/pizazz/IdeaProjects/iSport/dao/src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="org.pizazz.dao.mapper" targetProject="D:/huayunsky/IdeaProjects/iSport/dao/src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 要生成哪些表-->
        <!--<table tableName="admin" domainObjectName="Admin" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
      
    </context>

配置完成运行即可
