SSM框架通过mybatis-generator自动生成代码,

一、首先eclipse配置好maven环境,并且创建好一个SSM框架的工程

二、在pom.xml中添加plugin

    <build>
        <finalName>ssm_web</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/mybatis-generator/generatorConfig.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>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.40</version>
                        <scope>runtime</scope>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
        </pluginManagement> 
    </build>

注意:

1、pom中添加插件要在<build></build>标签里面,并且在这里指定数据库驱动,那么在下一步配置generatorConfig.xml的时候就不用在指定数据库驱动的本地路径;

2、src/main/resources/mybatis-generator/generatorConfig.xml指定的是generatorConfig.xml配置文件的路径,大家可以根据自己的实际情况调整;

三、generatorConfig.xml配置文件

<?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>
 <!-- <classPathEntry location="E:/maven/repository/mysql/mysql-connector-java/5.1.40/mysql-connector-java-5.1.40.jar"/> -->
 <context id="my" targetRuntime="MyBatis3">
  <commentGenerator>
   <property name="suppressDate" value="false" />
   <property name="suppressAllComments" value="true" />
  </commentGenerator>

  <jdbcConnection driverClass="com.mysql.jdbc.Driver"
   connectionURL="jdbc:mysql://127.0.0.1:3306/crm" userId="root"
   password="root" />

  <javaModelGenerator targetPackage="com.xdw.model"
   targetProject="F:/javawebworkspace/ssm_web/src/main/java">
   <property name="enableSubPackages" value="true" />
   <property name="trimStrings" value="true" />
  </javaModelGenerator>

  <sqlMapGenerator targetPackage="com.xdw.mapping"
   targetProject="F:/javawebworkspace/ssm_web/src/main/java">
   <property name="enableSubPackages" value="true" />
  </sqlMapGenerator>

  <javaClientGenerator targetPackage="com.xdw.dao"
   targetProject="F:/javawebworkspace/ssm_web/src/main/java" type="XMLMAPPER">
   <property name="enableSubPackages" value="true" />
  </javaClientGenerator>

  <table tableName="house_type" domainObjectName="HouseType">
   <!-- <property name="useActualColumnNames" value="true"/> -->
  </table>

 </context>
</generatorConfiguration>

配置讲解:

1、classPathEntry location在这里可以不用配置,因为之前pom中已经配置了数据库驱动;

2、jdbcConnection按照自己的数据库配置相应的驱动类,URL,用户名和密码;

3、javaModelGenerator,sqlMapGenerator,javaClientGenerator配置相应要生成的pojo类,DAO类和mapper对应的xml文件,targetPackage属性指定包名,targetProject指定自己工程的路径,

4、table标签配置数据库表和实体类的映射,tableName属性指定表名,domainObjectName指定生成的pojo类名;<property name="useActualColumnNames" value="true"/>如果配置的话,那么生成的实体类的属性名称就和数据库

  表的每个字段的名称一样,如果不配置,会将数据表里面的字段名称通过_连接的字段自动生成经典的驼峰表示法,比如我这里有个字段名为type_id,生成的属性名称为typeId;

   建议大家在数据库建表的时候采用_将单词分隔;

 

四、创建好之后点击maven build

在goals中填入mybatis-generator:generate,然后点击Run

也可以用maven命令行输入mvn mybatis-generator:generate

 

五、执行结果如下:
