Hibernate、Mybatis 通过数据库表反向生成java类和配置

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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.jacksoft.mybatis</groupId> <artifactId>mybatis-generator</artifactId> <version>0.0.1-SNAPSHOT</version> <properties> <mybatis-generator.version>1.3.1</mybatis-generator.version> <mysql.version>5.1.13</mysql.version> <mybatis.version>3.0.3</mybatis.version> </properties> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>${mybatis-generator.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> </dependencies> <build> <finalName>mybatis-generator</finalName> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>${mybatis-generator.version}</version> <dependencies> <!-- 数据库驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> </dependencies> <!-- 自动生成 --> <executions> <execution> <id>Generate MyBatis Artifacts</id> <goals> <goal>generate</goal> </goals> <configuration> <configurationFile>src/main/resources/mysqlGeneratorConfig.xml</configurationFile> <overwrite>true</overwrite> <jdbcDriver>com.mysql.jdbc.Driver</jdbcDriver> <jdbcURL>jdbc:mysql://localhost:3306/springmvc_mybatis</jdbcURL> <jdbcUserId>root</jdbcUserId> <jdbcPassword></jdbcPassword> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> </project>

3、添加mysqlGeneratorConfig.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">

<generatorConfiguration>

    <context id="mysqlTables" targetRuntime="MyBatis3">
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/springmvc_mybatis" userId="root"
            password="" />

        <!-- 指定生成的类型为java类型，避免数据库中number等类型字段 -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- 生成model模型，对应的包，存放位置可以指定具体的路径,如/ProjectName/src，也可以使用MAVEN来自动生成 -->
        <javaModelGenerator targetPackage="com.wjy.model"
            targetProject="MAVEN">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!--对应的xml mapper文件 -->
        <sqlMapGenerator targetPackage="com.wjy.mapper"
            targetProject="MAVEN">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!-- 对应的dao接口 -->
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.wjy.dao" targetProject="MAVEN">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>


        <table tableName="user_info" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
        <table tableName="course_info" domainObjectName="Course" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
        <table tableName="course_user_info" domainObjectName="CourseUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
    </context>
</generatorConfiguration>

4、生成
